Revision history for Perl extension App::Sqitch

1.6.1  2026-01-06T18:07:23Z
     - Fixed some ancient typos in sqitchtutorial-sqlite, with thanks to @ovid
       for the report!
     - Updated ClickHouse logic to always specify "default" as the hostname
       when connecting and the URI includes not hostname. This ensures it
       doesn't try to use `DSN=sqitch`, which is unlikely to be a configured
       DSN, and to align with the behavior of the ClickHouse client.

1.6.0  2025-10-06T13:00:00Z
     - Refactored the parsing of arrays for engines that don't support arrays
       (e.g., SQLite & Firebird). A new method in DBIEngine, `_parse_array`,
       replaces inline uses of `split`. This allows the tests to more
       consistently compare arrays as arrays, though `search_events` must now
       always parse `tags`, `requires`, and `conflicts`.
     - Added support for ClickHouse. It relies on the `clickhouse` (or
       `clickhouse-client`) CLI and ODBC driver. Like MySQL, it uses a
       database for the registry schema, where the tables use the `MergeTree`
       engine. It supports client certificate authentication and the
       ClickHouse client configuration file format.

1.5.2  2025-04-29T15:13:35Z
     - Added missing German translations, thanks to @0xflotus for the PR
       (#873)!
     - Fixed bug where the location of reworked script files did not respect
       the `deploy_dir`, `revert_dir`, or `verify_dir` options. Thanks to Neil
       Freeman for the report (#875)!
     - Updated the MySQL engine's installation of the `checkit()` function so
       that it no longer depends on permission-checking, since the current
       user may not have such permission. It instead attempts to create the
       function and ignores a failure due to a lack of permission. Thanks to
       Alastair Douglas for the report and solution (#874)!
     - Added missing CockroachDB templates. Thanks to @Peterbyte for the
       report (#878)!
     - Removed support for the `SNOWSQL_PORT` environment variable, which has
       long been deprecated by Snowflake and likely never did anything.
     - Fixed the quoting of the role and schema names on connecting to
       Snowflake, which was silently failing and thus not properly using the
       registry schema, which lead to a failure to find the registry. Broken
       in v1.5.1.
     - Added redaction of passwords from Snowflake URL query parameters in the
       display URL. Any query parameter matching `pwd` will now appear as
       "REDACTED".
     - Expanded the documentation of Snowflake key pair authentication in
      `sqitch-authentication.pod` to recommend setting sensitive ODBC
       parameters in an `odbc.ini` file rather than connection URL query
       parameters.
     - Switched to key pair authentication in the Snowflake CI workflows.
     - Fixed another test failure with some Firebird configurations and
       improved diagnostic output when an engine cannot be integration-tested.

1.5.1  2025-03-16T26:55:17Z
     - Fixed a bug introduced in v1.5.0 where the MySQL engine connected to
       the target database instead of the registry database. Thanks to
       @tiberiusferreira for the report (#862)!
     - Fixed test failures with some Exasol and Firebird configurations.
       Thanks to Slaven Rezić for the report (#858)!
     - Added some missing German translations, thanks to @0xflotus (#873).

1.5.0  2025-01-08T03:22:40
     - Fix improperly nested Pod headers that were incrementing two levels
       relative to their parent headers, which messed with the HTML output on
       sqitch.org.
     - Banned "[" and "]" in names (changes, tags, projects) because they
       muck with dependency parsing of the plan file. Thanks to Žiga Leber for
       the bug report (#829).
     - Updated the IPC methods that interact with engine clients to raise
       exception objects rather than strings, for more consistent error
       handling throughout.
     - Removed duplicate DBI error handling code from engines and tests.
     - Fixed an order of operation issue that prevented Sqitch from detecting
       Yugabyte before attempting to create an advisory lock, which resulted
       in an error for more recent Yugabyte releases. Thanks to Stefano
       Ricciardi for the report (#841).
     - Removed a wayward mention of the long-deprecated `SQITCH_URI`
       environment variable from the Oracle tutorial. Thanks to Austin Hanson
       for the report (#845).
     - Improved unexpected error output by including any previous exception.
     - Changed the "unknown engine" error to a runtime error, rather than
       development time, with a localized error message. The error loading
       the engine package and the stack trace remain available by using
       triple verbosity (`-vvv`). Thanks to Martin Fischer for the report
       (#838).
     - Changed the default error code from Oracle `sqlplus` from `SQL.SQLCODE`
       to `4`, because otherwise the exit code is returned `modulo 256`,
       meaning it can end up `0` for success for an SQL error code like

       binary logging and Sqitch lacks super user permissions. Thanks to Scott
       Edwards for the report and to Janosch Peters for the solution (#824).
     - Taught the Snowflake engine to detect when the Sqitch user lacks
       permission to create a schema and to skip the creation of the registry
       schema. Useful for cases when the registry schema was created in
       advance. Thanks to Peter Wimsey for the suggestion (#826).
     - Switched the MySQL engine from DBD::mysql to DBD::MariaDB for better
       compatibility with older versions of the MySQL client library and for
       its Unicode improvements. Thanks to Mark Tyrrell for the report and
       @tiberiusferreira and Perl Monks `1nickt` and`InfiniteSilence` for the
       feedback (#825).

1.4.1  2024-02-04T16:35:32Z
     - Removed the quoting of the role and warehouse identifiers that was
       added to the Snowflake engine in v1.4.0. Turns out Snowflake allows a
       warehouse to be specified in a different database, in which case dots
       are valid in the name and should not be quoted! So users must properly
       quote when necessary, but added notes to `sqitchtutorial-snowflake.pod`
       on the need to use URI escapes for special characters. Thanks to
       Patrick Sabo for the find, and to @marc-marketparts for validating
       that URI encoding works.
     - Added notes on URL encoding database URLs to `sqitch-target.pod`, the
       main reference for database URLs in the Sqitch documentation.
     - Fixed the output of the list of changes to be deployed or reverted to
       actually require `--verbose` twice, as described in the v1.4.0 changes,
       and not just once. Thanks to Erik Wienhold for the PR (#785)!
     - Removed the duplicate change name from the output of the list of
       changes to be deployed or reverted with `-VV`. Thanks to Erik Wienhold
       for the PR (#787)!
     - Fixed invalid template resolution when adding a singe change to
       multiple engines at once. Thanks to Christian Riedel for the detailed
       bug report (#795)!
     - Fixed Oracle and Firebird test failures due to incorrect use of `chmod`.
       Thanks to Slaven Rezić for the report and the fix (#807)!
     - Tests now require Test::Warn 0.31 or later, as newline handling issues
       cause test failures in earlier versions. Thanks to Slaven Rezić for the
       test reports and for identifying the issue.
     - Updated the locale configuration to fix issues in more recent versions
       of Perl, and added tests to ensure that the sqitch CLI executes and
       properly emits localized messages (except on Windows, where the language
       codes are incompatible).
     - Fixed an issue where the MySQL engine failed to recognize the MariaDB
       `mysql` client installed by Homebrew on macOS. Thanks to Carlos Ramos
       for the bug report and PR (#791)!

1.4.0 2023-08-01T23:37:30Z
     - Fixed Snowflake warehouse and role setup to properly quote identifiers
       unless they're valid unquoted identifiers or already quoted. Thanks to
       @marc-marketparts for the report (#685).
     - Fixed a bug reworking a change when a rework directory is configured
       but not created. Thanks to @jfeaver for the report (#686).
     - Output the list of changes to be deployed or reverted when `--verbose`
       is specified at least twice. Thanks to @vectro for the PR (#702).
     - Fixed the formatting of the log and plan commands to allow empty or `0`
       separators in lists of things (such as `%{0}t` for a list of tags).
       Thanks to @web-vertalo for the pull request (#703).
     - Updated the MySQL Tutorial to use 5.7 features. Thanks to Vlad
       Safronov for the PR (#705).
     - Deprecated the `no_prompt` and `no_prompt` attributes of
       App::Sqitch::Engine in favor of passing booleans to the `revert` and
       `verify` methods. The attributes still exist for reverse compatibility,
       but now emit warnings and will be removed in the future. Thanks to
       Thanks to @vectro for the PR (#704).
     - Added a warning for a double extension on the file names created
       by the `add` command. Thanks to @blairjordan for the PR (#724)!
     - Added the `revert.strict` boolean configuration variable which, when
       set to true, requires the specification of a change to revert to. It
       also disables the `rebase` and `checkout` commands, though the
       `rebase.strict` and `checkout.strict` variables, respectively, may
       override it. Use `revert.strict` to prevent accidental reverts in
       sensitive environments. Thanks to @vectro for the PR (#719; revised in
       #735)!
     - Fixed test failures due to a bug fix in the Perl URI module
       (libwww-perl/URI#13). Thanks to @bobfang for the report (#744)!
     - Fixed test failures due to a change in the generation of DBI DSN by
       URI::Oracle introduced by libwww-perl/URI-db#23.
     - Added a format option `%F` to `sqitch plan` that prints the path for
       the deploy file for each migration in the plan.
     - Changed the default location for the Oracle `sqlplus` client when the
       `ORACLE_HOME` environment variable is set. It now returns either
       `$ORACLE_HOME/bin/sqlplus` or `$ORACLE_HOME/sqlplus` if it exists
       and is executable (and ends in `.exe` on Windows). Otherwise it simply
       returns `sqlplus` as before, assuming it will be found in the path.
       Thanks to @vectro for the suggestion (#747).
     - Increased the required version of DBI to 1.631 or higher and removed
       a MySQL engine workaround for older versions.
     - Added detection of a missing registry schema on connect and conditions
       to avoid querying it when it does not exist. Fixes an issue where
       Sqitch might find a project record in the current schema instead of the
       expected registry schema. Thanks to @vectro for the report and
       investigation (#668)!
     - Fixed Snowflake and MySQL to properly raise errors on session query
       failures immediately after connection.
     - Fixed the handling of unique violations for deploy script hash
       uniqueness so that it no longer returns a database error but properly
       reports the issue in a more human-friendly error message. Thanks to
       Stefan Badenhorst for the reminder (#630).
     - Updated the registry SQL scripts for Vertica to always enable primary
       key and unique constraints. Unique constraints are now enabled for
       all database engines except Exasol and Snowflake.
     - Dropped support for Vertica 7.1, as unique constraint enforcement was
       not added until Vertica 7.2.
     - Increased minimum SQLite versions to 3.8.6, when unique constraint
       enforcement was added.
     - Removed remaining uses of the smartmatch operator, thus eliminating
       the Perl 5.38 warnings about its deprecation. (#769)
     - Added Cockroach to the list of valid engines recognized in command-line
       arguments (and a test to ensure new engines won't be omitted in the
       future). Thanks to @NOBLES5E for the spot (#772)!

1.3.1  2022-10-01T18:49:30Z
     - Fixed a bug introduced in v1.3.0 where the Postgres engine would
       always pass the port to `psql`, thus ignoring the `PGPORT` environment
       variable. Thanks to Cam Feenstra for the spot (#675)!
     - Fixed test failures on OSes where the local time zone cannot be
       determined. Thanks to Slaven Rezić for the test reports, and to
       Dave Rolsky for the solution (#672).
     - Updated the MySQL deploy/revert lock to be specific to the target
       database. This allows multiple instances of Sqitch to run at the
       same time on the same server as long as they're connecting to different
       databases. Thanks to Dmytro Kh for the report and discussion of the

       `sqitch-authentication`, as well as `$SNOWSQL_PRIVATE_KEY_PASSPHRASE`
       in `sqitch-environment`. Thanks to Casey Largent for figuring it out
       (#441).
     - Added the German localization. Thanks to Thomas Iguchi for the pull
       request (#451).
     - Renamed the French localization from "fr" to "fr_FR", so that systems
       will actually find it.
     - Added the `ask_yes_no()` method as a replacement for `ask_y_n()`, which
       is now deprecated. The new method expects localized responses from the
       user when translations are provided. Defaults to the English "yes" and
       "no" when no translation is available. Suggested by German translator
       Thomas Iguchi (#449).
     - Fixed a bug where only project without a URI was allowed in the
       registry. Thanks to Conding-Brunna for the report (#450).
     - Clarified the role of project URIs for uniqueness: They don't allow
       multiple projects with the same name, but do prevent the deployment of
       a project with the same name but different URI.
     - Fixed an issue where target variables could not be found when a target
       name was not lowercase. Thanks to @maximejanssens for the report
       (#454).
     - Now require Config::GitLike 1.15 or higher.
     - Fixed the indentation of variables emitted by the `show` actions of the
       `target` and `engine` commands, fixing a "Negative repeat count does
       nothing" warning in the process. Thanks to @maximejanssens for the
       report (#454).
     - Fixed a Snowflake test failure when the current system username has a
       space or other character requiring URI escaping. Thanks to Ralph
       Andrade for the report (#463).
     - Fixed an issue where a wayward newline in some versions of SQLite
       prevented Sqitch from parsing the version. Thanks to Kivanc Yazan
       for the report (#465) and the fix (#465)!
     - Fixed an error when Sqitch was run on a system without a valid
       username, such as some Docker environments. Thanks to Ferdinand Salis
       for the report (#459)!
     - When Sqitch finds the registry does not exist on PostgreSQL, it now
       sends a warning to the PostgreSQL log reporting that it will initialize
       the database. This is to reduce confusion for folks watching the
       PostgreSQL error log while Sqitch runs (#314).

0.9999 2019-02-01T15:29:40Z
     [Bug Fixes]
     - Fixed a test failure with the MySQL max limit value, mostly exhibited
       on BSD platforms.
     - Removed fallback in the PostgreSQL engine on the `$PGUSER` and
       `$PGPASSWORD` environnement variables, as well as the system username,
       since libpq does all that automatically, and collects data from other
       sources that we did not (e.g., the password and connection service
       files). Thanks to Tom Bloor for the report (issue #410).
     - Changed dependency validation to prevent an error when a change required
       from a different project has been reworked. Previously, when requiring a
       change such as `foo:greeble`, Sqitch would raise an error if
       `foo:greeble` was reworked, suggesting that the dependency be
       tag-qualified to eliminate ambiguity. Now reworked dependencies may be
       required without tag-qualification, though tag-qualification should still
       be specified if functionality as of a particular tag is required.
     - Added a workaround for the shell quoting issue on Windows. Applies to
       IPC::System::Simple 1.29 and lower. See
       [pjf/ipc-system-simple#29](https://github.com/pjf/ipc-system-simple/pull/29)
       for details (#413).
     - Fixed an issue with the MariaDB client where a deploy, revert, or
       verify failure was not properly propagated to Sqitch. Sqitch now passes
       `--abort-source-on-error` to the Maria `mysql` client to ensure that
       SQL errors cause the client to abort with an error so that Sqitch can
       properly handle it. Thanks to @mvgrimes for the original report and,
       years later, the fix (#209).
     - Fixed an issue with command argument parsing so that it truly never
       returns a target without an engine specified, as documented.
     - Removed documentation for methods that don't exist.
     - Fixed test failures due to a change in Encode v2.99 that's stricter
       about `undef` arguments that should be defined.

     [Improvements]
     - The Snowflake engine now consults the `connections.warehousename`,
       `connections.dbname`, and `connections.rolename` variables in the
       SnowSQL configuration file (`~/.snowsql/config`) before falling back on
       the hard-coded warehouse name "sqitch" and using the system username as
       the database name and no default for the role.
     - Switched to using a constant internally to optimize windows-specific
       code paths at compile time.
     - When `deploy` detects undeployed dependencies, it now eliminates
       duplicates before listing them in the error message.
     - Now requiring IO::Pager v0.34 or later for its more consistent
       interface.
     - Added notes about creating databases to the tutorials. Thanks to Dave
       Rolsky for the prompt (#315).
     - Added a status message to tell the user when the registry is being
       updated, rather than just show each individual update. Thanks to Ben
       Hutton for the suggestion (#276).
     - Added support for a `$SQITCH_TARGET` environment variable, which takes
       precedence over all other target specifications except for command-line
       options and arguments. Thanks to @mvgrimes for the suggestion (#203).
     - Fixed target/engine/change argument parsing so it won't automatically
       fail when `core.engine` isn't set unless no targets are found. This
       lets engines be determined strictly from command-line arguments --
       derived from targets, or just listed on their own -- whether or not
       `core.engine` is set. This change eliminates the need for the
       `no_default` parameter to the `parse_args()` method of App::Sqitch
       Command. It also greatly reduces the need for the core `--engine`
       option, which was previously required to work around this issue (see
       below for its removal).
     - Refactored config handling in tests to use a custom subclass of
       App::Sqitch::Config instead of various mocks, temporary files, and the
       like.
     - Added advice to use the PL/pgSQL `ASSERT()` function for verify scripts
       to the Postgres tutorial. Thanks to Sergii Tkachenko for the PR (#425).

     [Target Variables]
     - The `verify` command now reads `deploy.variables`, and individual
       `verify.variables override `deploy.variables`, on the assumption that
       the verify variables in general ought to be the same as the deploy
       variables. This makes `verify` variable configuration consistent with
       `revert` variable configuration.
     - Variables set via the `--set-deploy` option on the `rebase` and
       `checkout` commands no longer apply to both reverts and deploys, but
       only deploys. Use the `--set` option to apply a variable to both
       reverts and deploys.
     - Added support for core, engine, and target variable configuration. The
       simplest way to use them is via the `--set` option on the `init`,
       `engine`, and `target` commands. These commands allow the configuration
       of database client variables for specific engines and targets, as well
       as defaults that apply to all change execution commands (`deploy`,
       `revert`, `verify`, `rebase`, and `checkout`). The commands merge the
       variables from each level in this priority order:
       * `--set-deploy` and `--set-revert` options on `rebase` and `checkout`
       * `--set` option
       * `target.$target.variables`
       * `engine.$engine.variables`
       * `deploy.variables`, `revert.variables`, and `verify.variables`
       * `core.variables`
       See `sqitch-configuration` for general documentation of of the
       hierarchy for merging variables and the documentation for each command
       for specifics.

     [Options Unification]
     - Added the `--chdir`/`--cd`/`-C` option to specify a directory to change
       to before executing any Sqitch commands. Thanks to Thomas Sibley for
       the suggestion (#411).
     - Added the `--no-pager` option to disable the pager (#414).
     - Changed command-line parsing to allow core and command options to
       appear anywhere on the line. Previously, core options had to come
       before the command name, and command options after. No more. The caveat
       is that command options that take arguments should either appear after
       the command or use the `--opt=val` syntax instead of `--opt val`, so
       that Sqitch doesn't think `val` is the command. Even in that case, it
       will search the rest of the arguments to find a valid command.
       However, to minimize this challenge, the documentation now suggests
       and demonstrates putting all options after the command, like so:
       `sqitch [command] [options]`.
     - Simplified and clarified the distinction between core and command
       options by removing all options from the core except those that affect
       output and runtime context. The core options are:
       * -C --chdir --cd <dir>  Change to directory before performing any actions
       *    --etc-path          Print the path to the etc directory and exit
       *    --no-pager          Do not pipe output into a pager
       *    --quiet             Quiet mode with non-error output suppressed
       * -V --verbose           Increment verbosity
       *    --version           Print the version number and exit
       *    --help              Show a list of commands and exit
       *    --man               Print the introductory documentation and exit
     - Relatedly, single-letter core options will now always be uppercase,
       while single-letter command options will be lowercase. As such, `-V`
       has been added as an alias for `--version`, although `-v` remains for
       now, undocumented. It may be removed in the future should a compelling
       use for `-v` in a command be discovered.
     - All other options have been moved to the commands they affect. Their
       use should remain mostly unchanged now that command options are parsed
       from anywhere on the command-line, although we recommend that all
       options come after commands. The options were moved as follows:
       * `--registry`, `--client`, `--db-name`, `--db-user`, `--db-host`, and
         `--db-port` (and their aliases) have been moved to the `checkout`,
         `deploy`, `log`, `rebase`, `revert`, `status`, `upgrade`, and
         `verify` commands.
       * `--plan-file` and `--top-dir` (deprecated; see below) have been moved
         to the `add`, `bundle`, `checkout`, `deploy`, `rebase`, `revert`,
         `rework`, `show`, `status`, `tag`, and `verify` commands. They were
         already supported by the `init`, `engine`, and `target` commands
         (where `--top-dir` is not deprecated).
     - Because some command options conflicted with core options, a few
       options have been removed altogether, including:
       * The `--verbose` option on the `--engine` and `--target` commands has
         been removed, but no visible change should be apparent, since those
         commands now read the core `--verbose` option.
       * The undocumented `--dir` alias for `--top-dir` has been removed, as
         it conflicted with the option of the same name but different meaning
         in the `init`, `engine`, and `target` commands.
       * The `-d` alias for `--set-deploy` in the `rebase` and `checkout`
         commands has been changed to `-e` so as not to conflict with the `-d`
         alias for `--db-name`.
       * Added tests for all commands to ensure none of their options conflict
         with core options. Will help prevent conflicts in the future.

     [Deprecations & Removals]
     - Deprecated the `--top-dir` option in favor of `--chdir` with a warning
       except when used for configuration in the `init`, `engine`, and
       `target` commands.
     - Removed the core `--deploy-dir`, `--revert-dir`, and `--verify-dir`
       options, which have been deprecated and triggering warnings since
       v0.9993 (August 2015). The `--dir` option to the `init`, `engine`, and
       `target` commands remains the favored interface for specifying script
       directories.
     - Removed the deprecated core `--engine` option. The `init` command still
       supports it, while other commands are able to parse the engine name as
       an argument --- e.g., `sqitch deploy mysql` --- or implicitly as part
       of a target, as in `sqitch revert db:pg:tryme`. When Sqitch is unable
       to determine the engine for a command, the error message no longer
       mentions `--engine` and instead suggests specifying the engine via the
       target. This option never triggered an error, but demonstration of its
       use has been limited to `init` examples.
     - Removed support for reading the `core.$engine` configuration, which has
       been deprecated with warnings in favor of `engine.$engine` since 0.997
       (November 2014). The `sqitch engine update-config` action remains
       available to update old configurations, but may be removed in the
       future.
     - Removed the `--deploy`, `--revert`, and `--verify` options on the `add`
       command, as well as their `--no-*` variants. They have been deprecated
       with warnings in favor of the `--with` and `--without` options since
       v0.990 (January 2014).
     - Removed the `--deploy-template`, `--revert-template`, and
       `--verify-template` options to the `add` command. They have been
       deprecated with warnings in favor of the `--use` option since v0.990
       (January 2014).
     - Removed the `add.deploy_template`, `add.revert_template`, and
	   `add.verify_template` configuration settings. They have been deprecated
	   with warnings in favor of the `add.templates` configuration section
       since v0.990 (January 2014).
     - Removed the `@FIRST` and `@LAST` symbolic tags, which have been
       deprecated with warnings in favor of `@ROOT` and `@HEAD`, respectively,
       since 0.997 (November 2014).
     - Removed the command-specific options with the string "target" in them,
       such as `--to-target`, `--upto-target`, which have been deprecated with
       warnings in in favor of options containing the string "change", such as
       `--to-change` and `--upto-change`, since v0.997 (November 2014).
     - Remove the `engine` and `target` command `set-*` actions and their
       corresponding methods, which have been deprecated in favor of the
       `alter` action since v0.9993 (August 2015).
     - Removed the automatic updating of change and tag IDs in the Postgres
       engine. This functionality was added in v0.940 (December 2012), when
       Postgres was the only engine, and the SHA-1 hash for change and tag IDs
       was changed. There were very few deployments at the time, and all
       should long since have been updated.

     [API Changes]
     - Added the URI-overriding parameters `user`, `host`, `port`, and
       `dbname` to App::Sqitch::Target so that command options can be used to
       easily set them.
     - Added support for passing attribute parameters to the `all_targets`
       group constructor on App::Sqitch::Target, so that command-line options
       can be used to assign attributes to all targets read from the
       configuration.
     - Aded the `target_params` method to App::Sqitch::Command and updated all
       commands to use it when constructing targets. This allows commands to
       define options for Target parameters, as required for moving options to
       commands as described above.
     - Added the `class_for` method to App::Sqitch::Command so that the new
       options parser described above can load a command class without
       instantiating an instance. Useful for searching command-line arguments
       for a command name.
     - Added the `create` constructor to App::Sqitch::Command to let Sqitch
       instantiate an instance of a command once it finds one via `class_for`.
       Previously, Sqitch used the `load` method, which handled the
       functionality of both `class_for` and `create`. That method still
       exists but is used only in tests.
     - Added the ConnectingCommand role to define database connection options
       for the commands that need them.
     - Added the ContextCommand role to define command options for the
       location of the plan file and top directory. This is also where use of
       the deprecated form of `--top-dir` triggers a warning.
     - Removed the `verbosity` attribute from App::Sqitch::Command::engine and
       App::Sqitch::Command::target, since the `--verbose` option is no longer
       needed. These commands now rely on the core `--verbose` option.
     - Removed the copying of core options from the target class and
       TargetConfigCommand role, since the attributes fetched from there are
       no longer core options, but provided as attribute parameters to the
       constructors by commands.
     - Removed documentation for the optional `config` parameter to the
       `all_targets` constructor of App::Sqitch::Target, since it was never
       used by Sqitch. It always fetched the config from the required `sqitch`
       parameter. Support for the `config` parameter has not been removed,
       since third-parties might use it.
     - Removed the `set_*` methods in the `engine` and `target` commands,
       which have been deprecated in favor of the new `alter` method since
       v0.9993 (August 2015).
     - Removed the `old_id` and `old_info` methods from Change and Tag, which

       with the specified engine. Pass once for each engine. See the README
       for the list of supported engines.
     - Added a check for Hash::Merge 0.298 during installation, since that
       release has a fatal bug that breaks Sqitch. If it's installed, the
       installer will issue a warning and added v0.299 to its list of
       dependencies. Thanks to Slaven Rezić for the suggestion (#377).
     - Fixed the PostgreSQL engine so it properly checks the `psql` client
       version to determine whether or not the `:registry` variable is
       supported. Previously it relied on the server version, which would fail
       if the server version was greater than 8.4 but the `psql` client was
       not. Thanks to multiple folks reporting issues with registry names and
       search paths (#314).
     - The plan parser will now complain if a change specifies a duplicate
       dependency. This should be less confusing than a database unique
       violation. Thanks to Eric Bréchemier for the suggestion (#344).
     - Moved the project to its own GitHub organization,
       [Sqitchers](https://github.com/sqitchers).
     - Fixed likely cause of Oracle buffer allocation bug when selecting
       timestamp strings. Thanks to @johannwilfling for the bug report and to
       @nmaqsudov for the analysis and solution (#316).
     - Changed the way the conninfo string is passed to `psql` to eliminate
       argument ordering problems on Windows. Thanks to @highlowhighlow for
       the report (#384).
     - Added `$SQITCH_USERNAME` environment variable to complement
       `$SQITCH_PASSWORD`. It can be used to override the username set in
       for a target.
     - Added the `$SQITCH_FULLNAME` and `$SQITCH_EMAIL` environment
       variables, which take precedence over the values of the `user.name` and
       `user.email` config variables.
     - Added the `$SQITCH_ORIG_SYSUSER`, `$SQITCH_ORIG_FULLNAME` and
       `$SQITCH_ORIG_EMAIL` environment variables. For those situations when
       Sqitch attempts to read OS data for user information, These new
       environment variables override these system-derived values. The
       intention is to allow an originating host to set these values on
       another host where Sqitch will actually execute.
     - Fixed an error triggered by whitespace trailing an engine name in the
       configuration. Thanks to Jeremy Simkins for the report (#400).
     - Refactored the engine-specific username and password attributes to
       support a consistent search for values. Sqitch searches first for one
       of its own environment variables (`$SQITCH_USERNAME` and
       `$SQITCH_PASSSWORD`), then the target URI, and finally any engine-
       specific values, which might include additional environment variables,
       configuration files, the system user, or none at all.
     - Database engines that implicitly relied on username and/or password
       environment variables or on the system username now explicitly rely on
       them. These include the Firebird, MySQL, Postgres, and Vertical
       engines. This change should exhibit no change in the behavior of these
       engines.
     - Added support for the `$MYSQL_HOST` and `$MYSQL_TCP_PORT` environment
       variables to the MySQL engine.
     - Documented all supported engine-specific environment variables in the
       sqitch-environment guide.
     - Renamed the sqitch-passwords guide to sqitch-authentication and added a
       section on username specification.
     - Updated all URLs to use the https scheme. Only exceptions are tt2.org,
       which doesn't support TLS, and conferences.embarcadero.com, which
       appears to be down.

0.9997 2018-03-15T21:13:52Z
     - Fixed the Firebird engine to properly detect multiple instances of a
       change specified to `revert` and `verify`, matching the behavior of
       displaying tag-qualified alternates added to the other engines in
       v0.9996.
     - Fixed test failure on Windows.
     - Updated the MySQL and PostgreSQL tests to use process-specific database
       names, to try to avoid conflicts when tests are being run by multiple
       processes on the same box, as happens with CPAN smoke testing boxes.
     - Fixed an issue where Sqitch would sometimes truncate the registry
       version number fetched from Postgres, most likely because the Perl
       runtime was using 32-bit integers. Fixed by casting the version to text
       in the query, before Perl ever see it. Thanks to Malte Legenhausen for
       the report (#343).
     - The MySQL engine will now read the username from MySQL configuration
       files. Thanks to Eliot Alter for the bug report (#353).
     - Added Italian translation, with thanks to Luca Ferrari and @BeaData!
     - Improved multi-value config examples in the `sqitch-config`
       documentation to be a bit less confusing. Thanks to Emil for reporting
       where he got confused!
     - Added the Exasol engine. Thanks to Johan Wärlander for the PR (#362)!
     - Fixed an issue where URI::db needed to be explicitly loaded. Thanks to
       Hugh Esco for the report (#370)!
     - Changed the exit value for `rebase` and `revert` from 1 to 0 when there
       is no work to do. This is to match the expectation of non-zero exit
       statuses only when a command is unsuccessful, as well as the behavior
       of `deploy` as of v0.995. Nothing to do is considered successful.
       Thanks to Paul Williams for the PR (#374)!
     - Update `psql` options to use a conninfo string to honor connection
       parameter key words for PostgreSQL targets. It can now take advantage
       of the connection service file using `db:pg:///?service=$PGSERVICE` as
       well as other connection parameters. Thanks to Paul Williams for the PR
       (#375)!

0.9996 2017-07-17T18:33:12Z
     - Fixed an error where Oracle sometimes truncated timestamp formats so
       that date parsing failed. Thanks to Johann Wilfling for the report and
       @nmaqsudov for the solution (#316).
     - Added pager configuration, prioritizing the new `core.pager`
       configuration variable over the `$PAGER` environment variable. The new
       `$SQITCH_PAGER` environment variable trumps all. Thanks to Yati Sagade
       for the pull request (#329).
     - Documented the `core.editor` configuration variable.
     - Updated PostgreSQL registry detection to avoid errors when not running
       Sqitch as a superuser and the registry schema already exists. Done by
       looking for the `changes` table in the `pg_tables` view instead of
       looking for the registry schema in the `pg_namespace` catalog table,
       and by using `CREATE SCHEMA IF NOT EXISTS` on PostgreSQL 9.3 and
       higher. Thanks to @djk447 for the pull request (#307).
     - Updated PostgreSQL registry detection to avoid errors when the `psql`
       client is newer than the server version. Sqitch now fetches the version
       from the server instead of parsing it from the client.
     - Removed `no Moo::sification`, to allow modules to be used by Moose
       applications. Replaced with tests to make sure Sqitch itself never uses
       Moose. Thanks to @perigrin for the PR (#332).
     - Specifying a change before a target name on the command-line no longer
       ignores the target (#281).
     - The `--db-*` options are now more consistently applied to a target,
       including when the target is specified as a URI (#293).
     - `HEAD` and `ROOT` are now properly recognized as aliases for `@HEAD`
       and `@ROOT`, when querying the database. This was supposedly done in
       v0.991, but due to a bug, it wasn't really. Sorry about that.
     - The `revert` and `verify` commands will now fail if a change is
       specified and matches multiple changes. This happens when referencing a
       reworked change only by its name. In this case, Sqitch will emit an
       error listing properly tag-qualified changes to use. Suggested by Jay
       Hannah (#312).
     - Sqitch no longer returns an error when a target name is passed to a
       command and the default target's plan file does not exist (#324).
     - Added missing options to the `rework` usage statement. Thanks to Jay
       Hannah for the PR (#342).
     - Passing an engine name or plan file as the `<database>` parameter to
       the `log`, `status`, and `upgrade` commands now works correctly,
       matching what the documentation has said for some time (#324).
     - Added the `--target` option to the `plan` and `show` commands.
     - Added the `<database>` parameter to the `plan` command.
     - Sqitch now loads targets from all config files, not just the local
       file, when trying to determine if a `<database>` parameter is a plan
       file name.
     - Improved the error message when a change is found more than once in a
       plan, typically a reworked changed referenced only by name. The error
       will no longer be "Key at multiple indexes", but "Change is ambiguous.
       Please specify a tag-qualified change:", followed by a list of
       tag-qualified variants of the change.
     - Fixed a bug where the verify command would return a database error when
       it finds no registry. Now it reports that the registry wasn't found in
       the database.

0.9995 2016-07-27T09:23:55Z
     - Taught the `add` command not to ignore the `--change` option.
     - The `add` command now emits a usage statement when no change name is
       passed to it.
     - The `add` command now helpfully suggests using the --change option when
       attempting to add a change with the same name as a target. Thanks to
       Ivan Nunes for the report!
     - The `tag` command now helpfully suggests using the --tag option when
       attempting to add a tag with the same name as a target.
     - Added `--global` as an alias for `--user` to the `config` command. This
       alias benefits the muscle memory of Git users.
     - Added a note for Git users to the `sqitch-revert` documentation, to
       head off potential confusion with `git revert`. Thanks to Eric
       Bréchemier for the "time travel" analogy and wording.
     - Fixed an "uninitialized value" error when creating a registry database
       on Windows. Thanks to Steven C. Buttgereit for the report (Issue #289).
     - Fixed editor selection to prioritize the `core.editor` configuration
       variable over the `$EDITOR` environment variable. The `$SQITCH_EDITOR`
       environment variable still trumps all. Thanks to Jim Nasby for the pull
       request (#296).
     - Added detection of the `$VISUAL` environment variable to Editor
       selection, prioritized after the `core.editor` configuration variable
       and before the `$EDITOR` environment variable. Thanks to Jim Nasby for
       the pull request (#296).
     - Updated the DateTime code to set the locale via `set_locale()` instead
       of `set()`, as the latter may actually change the local time
       unintentionally, and has been deprecated since DateTime v1.04. Thanks
       to Dave Rolsky for the pull request (#304).

0.9994 2016-01-08T19:46:43Z
     - Reduced minimum required MySQL engine from 5.1.0 to 5.0.0. Thanks to
       @dgc-wh for testing it (Issue #251).
     - Fixed floating-point rounding issue with SQLite registry versions on
       Perls with 16-byte doubles. Thanks to H. Merijn Brand for the report
       and testing.
     - Fixed an error when adding an engine with the `engine` command. Thanks
       to Victor Mours for the report and fix!
     - Updated the Oracle engine to support Oracle Wallet connection strings,
       where no username or host is in the connection URI. Thanks to Timothy
       Procter for the patch!
     - Improved the installer's selection of the prefix in which to install
       `etc` files to better match the `--installdirs` option, which defaults
       to the "site" directories. Thanks to @carragom for the pull request
       (#265).
     - Added missing dash to `-engine` in sample calls to `sqitch init` in the
       tutorials. Thanks to Andrew Dunstan for the spot (Issue #268).
     - Fixed broken Vertica documentation links.
     - Attempting to revert a database with no associated registry no longer
       reports the registry as version 0, but correctly reports that no
       registry can be found. Thanks to Arnaldo Piccinelli for the spot (Issue
       #271).
     - Fixed the search for change IDs in engines to match the search for
       changes. Specifically, change ID search now properly handles the
       offset characters `~` and `^`. This bug mainly affected the `verify`
       command, but it's good to address the inconsistency, done mainly by
       adding the `find_change_id` and `change_id_offset_from_id` methods to
       complement the `find_change` and `change_offset_from_id` methods.
       Thanks to Andrew Dunstan for the spot (Issue #272).
     - Fixed the `flips` table example in the MySQL tutorial. It was
       inappropriately copied from the PostgreSQL tutorial at some point.
       Thanks to Jeff Carpenter for the spot (Issue #254)!

0.9993  2015-08-17T17:55:26Z
     [Bug Fixes]
     - Eliminated test failures due to warnings from DateTime::Locale when
       `LC_TIME` is set to C.UTF-8. Thanks to Shantanu Bhadoria for the report
       and Dave Rolsky for the workaround.
     - Fixed an error checking the registry version when the local uses a
       comma for decimal values. Thanks to Steffen Müller for the report
       (Issue #234).
     - Worked around an error setting the MySQL storage engine using versions
       of DBI prior to 1.631. Thanks to melon-babak for the report!
     - Fixed an error from the Oracle engine when deploying more than 1000
       changes. Thanks to Timothy Procter and Minh Hoang for the report and
       testing the fix.
     - Fixed a bunch of typos in error messages, comments, and documentation.
       Thanks to Dmitriy for the pull request!
     - Fixed test failures due to new warnings from File::Path on Perl
       5.23.1.
     - On Firebird, Looking up a change and tag in the database (via the
       `--onto` option to `rebase` or the `--to` option to `revert`, among
       others) would sometimes return the incorrect change if the change has
       been reworked two or more times. Was fixed for the other engines in
       v0.9991.
     - Fixed the `--all` option used to apply a command to all known targets
       so that it loads only targets specified by the local configuration.
       Otherwise, user and system configuration can get in the way when they
       specify engines and targets not used by the current project.
     [Improvements]
     - Added support for the `--set` option when deploying to MySQL. Thanks to
       Chris Bandy for figuring out how to do it!
     - Added support for a "reworked directory". By default, reworked change
       scripts live in the deploy, revert, and verify directories along with
       all the other change scripts. But if that starts to get too messy, or
       you simply don't want to see them, add a `reworked_dir` setting to the
       core, engine, or target config and reworked scripts will be stored
       there, instead. Also supported are `reworked_deploy_dir`,
       `reworked_revert_dir`, and `reworked_verify_dir`.
     - Added the `--dir` option to the `init`, `engine`, and `target`
       commands.
     - Copied the core configuration options (`--engine`, `--target`,
       `--plan-file`, `--registry`, etc.) to the `init`, `engine`, and
       `target` commands. This means that they can be specified after the
       command, which is a bit more natural. It also means that the
       `--registry` and `--client` options of the `target` are no longer
       deprecated.
     - The `init` command no longer writes out commented values for the
       `deploy_dir`, `revert_dir`, or `verify_dir` settings. I think these
       settings are not commonly used, and it would start to get crowded if we
       also added their "reworked" variants, which will be used still less.
     - Added the `alter` action to the `engine` and `target` commands to set
       engine and target properties.
     - Added support for setting reworked directories to the `engine` and
       `target` commands.
     - Reformatted the output of the `engine` and `target` command `show`
       actions to include reworked directories, and to bit a bit less flat.
     - Attempting to add or alter an engine with a target URI that connects to
       a different engine now triggers an error. For example, you can't set
       the target for engine `pg` to `db:sqlite:`.
     - The `add` and `alter` actions of the `engine` and `target` commands
       now create script directories if they don't already exist.
     - The `add` action of the `engine` and `target` commands now creates a
       plan file if one does not exist in the specified location for the
       engine or target.
     - Added the `deploy_dir`, `revert_dir`, and `verify_dir` methods to
       App::Sqitch::Plan::Change. Each points to the proper directory for the
       target depending on whether or not the change has been reworked.
     - In the MySQL engine, the following URI query params will be converted
       to options passed to the command-line client, if they're present:
       * mysql_compression=1   => --compress
       * mysql_ssl=1           => --ssl
       * mysql_connect_timeout => --connect_timeout
       * mysql_init_command    => --init-command
       * mysql_socket          => --socket
       * mysql_ssl_client_key  => --ssl-key
       * mysql_ssl_client_cert => --ssl-cert
       * mysql_ssl_ca_file     => --ssl-ca
       * mysql_ssl_ca_path     => --ssl-capath
       * mysql_ssl_cipher      => --ssl-cipher
     [Documentation]
     - Added the "Overworked" section to sqitch-configuration guide with an
       example of how to move reworked change scripts into a `reworked_dir`.
     [Deprecations]
     - Deprecated the `set-*` actions in the `engine` and `target` commands in
       favor of the new `alter` action.
     - The core `--deployed-dir`, `--revert-dir`, and `--verify-dir` options
       are deprecated in favor of the `--dir` option on the `init`, `engine`,
       and `target` command.

     - On PostgreSQL, Sqitch now sets the `client_encoding` parameter to
       `UTF8` for its own connection to the database. This ensures that data
       sent to and from the database should always be properly encoded and
       decoded. Users should still set the proper encodings for change scripts
       as appropriate.
     - Fixed test failures due to path differences on Windows.
     - DateTime::TimeZone is now explicitly required in an attempt to head off
       "Cannot determine local time zone" errors.
     - Corrected some typos and thinkos in `sqitchtutorial-oracle`, thanks to
       George Hartzell.
     - Improved the script to upgrade an Oracle registry to v1.0 to support
       versions prior to Oracle 12, thanks to Timothy Procter.
     - Added missing closing parenthesis to the "Nothing to deploy" message.
       Thanks to George Hartzell for the pull request (Issue #226).
     - Replaced the unique constraint on the `script_hash` column in the
       `changes` registry table with a unique constraint on `project` and
       `script_hash`. This is to allow a deploy script to be used in more than
       one project in a single database. This change increments the registry
       version to v1.1. Thanks to Timothy Procter for the report.
     - Updated the registry check constraints to have consistent names on the
       engines that support them. This will make it easier to modify the
       constraints in the future.
     - Fixed precision issues with the registry version on MySQL and Firebird.
     - Added comment to sqitch-passwords guide that MySQL::Config is required
       to read passwords from the MySQL configuration files. Thanks to
       Sterling Hanenkamp for the patch!

     [Improvements]
     - Reduced minimum required MySQL engine from 5.6.4 to 5.1.0. Versions
       prior to 5.6.4 lose the following features:
       * Versions earlier than 5.6.4 is fractional second precision on
         registry `DATETIME` columns. Since the ordering of those timestamps
         is so important to the functioning of Sqitch, it will sleep in 100 ms
         increments between logging changes to the registry until the time has
         ticked over to the next second. Naturally, reverts and deploys will
         be a little slower on versions of MySQL before 5.6.4, but accurate.
       * Versions earlier than 5.5.0 lose the `checkit()` functions, which
         would otherwise be used to emulate CHECK constraints in the registry,
         as well as in user-created verify scripts, as recommended in the
         MySQL tutorial, `sqitchtutorial-mysql`.
     - Added a script to update the `DATETIME` columns in a MySQL Sqitch
       registry that was upgraded to MySQL 5.6.4 or higher. It will be
       installed as `tools/upgrade-registry-to-mysql-5.6.4.sql` in the
       directory returned by `sqitch --etc`.
     - Added a script to add the `checkit()` function and registry triggers to
       emulate CHECK constraints to a MySQL Sqitch registry that was upgraded
       to MySQL 5.5.0 or higher. It will be installed as
       `tools/upgrade-registry-to-mysql-5.5.0.sql` in the directory returned
       by `sqitch --etc`.
     - The `init` command now throws an error when the plan file already
       exists and is invalid or defined for a different project. Thanks to
       Gabriel Potkány for the suggestion (Issue #214).
     - All commands that take target arguments can now specify them as engine
       names or plan file paths as well as target names and URIs.
     - Added the `--all` option and the `$command.all` configuration variable
       to the `add`, `rework`, `tag`, and `bundle` commands. This option tells
       the commands to do their thing for all plans known from the
       configuration, not just the default plan.
     - Pass engine, target, or plan file names to the `add`, `rework`, `tag`,
       and `bundle` commands` commands to specify specify one or more targets,
       engines, and plans to act on.
     - Added the `--change` option to the `add`, `rework`, and `tag` commands
       to distinguish the change to be added, reworked, or tagged from
       plan-specifying arguments, if necessary.
     - Added the `--tag` option to the `tag` command to distinguish the tag to
       be added from plan-specifying arguments, if necessary.
     - Changed the short variant of the `--conflicts` option to the `add` and
       `rework` commands from `-c` to `-x`. The `-c` option is now used as the
       short variant for `--change` (and `--conflicts` has almost certainly
       never been used, anyway).
     - Added the `engine` and `project` variables to the execution of script
       templates by the `add` command. The default templates now use it to
       make their first lines one of:
       * -- Deploy [% project %]:[% change %] to [% engine]
       * -- Revert [% project %]:[% change %] from [% engine]
       * -- Verify [% project %]:[% change %] on [% engine]
     [Bug Fixes]
     - DateTime::TimeZone::Local::Win32 is now required on Windows.
     - The MySQL engine no longer passes `--skip-pager` on Windows, since
       it is not supported there. Thanks to Gabriel Potkány for the report
       (Issue #213).
     - Fixed "no such table: changes" error when upgrading the SQLite
       registry.
     - Fixed upgrade failure on PostgreSQL 8.4. Thanks to Phillip Smith for
       the report!
     - Fixed an error when the `status` command `show_changes` and `show_tags`
       configuration variables were set. Thanks to Adrian Klaver for the
       report (Issue #219).
     - Fixed `log` and `plan` usage statements to properly spell `--abbrev`.
       Thanks to Adrian Klaver for the report (Issue #220).
     - Fixed the formatting of change notes so that a space precedes the `#`
       character whether the note was added by the `--note` option or via an
       editor.
     - Fixed a bug when parsing plan files with DOS/Windows line endings.
       Thanks to Timothy Procter for the report (Issue #212).
     - Looking up a change and tag in the database (via the `--onto` option to
       `rebase` or the `--to` option to `revert`, among others) would
       sometimes return the incorrect change if the change has been reworked
       two or more times. Thanks to BryLo for the report!
     [Documentation]
     - Updated docs to be consistent in referring to the location of the system
       configuration and template location as `$(prefix)/etc/sqitch`. Also
       added notes pointing to the `--etc-dir` to find out exactly what that
       resolves to. Suggested by Joseph Anthony Pasquale Holsten (Issue #167).
     [Deprecations]
     - Reverted deprecation of the database connection options. Target URIs
       are still generally preferred, but sometimes you want to use a target
       but just change the user name or database name. Retaining the options
       is the easiest way to do this. Plus, a fair number of people have
       scripts that use these options, and it seems petty to break them. Sorry
       for the double-take here! The list of un-deprecated options is:
       * `--db-client`
       * `--db-host`
       * `--db-port`
       * `--db-username`
       * `--db-password`
       * `--db-name`

0.999  2015-02-12T19:43:45Z
     - Improved MySQL missing table error detection by relying on error codes
       instead of matching a (possibly localized) error string.
     - Made the registry upgrade more transparent when deploying. Sqitch is
       now is a little more vigilant in checking for things being out-of-date
       and updating them.
     - Fixed an issue where the `status` command would return an error when
       run against a an older version of the registry.
     - Fixed a Postgres test failure when DBD::Pg is installed but psql is not
       in the path.
     - Now require Config::GitLike 1.15 to build on Windows in order to avoid
       test failures when Cwd::abs_path dies on non-existent paths.
     - Clarified the behavior of each `deploy` reversion mode with regard to
       deploy script vs. verify script failures, and with the expectation that
       deploy scripts are atomic.
     - Target passwords can now be set via a single environment variable,
       `$SQITCH_PASSWORD`. Its value will override URI-specified password.
     - Added the sqitch-passwords and sqitch-environment guides.

0.998  2015-01-15T22:17:44Z
     - Fixed a bug in `sqitch engine update-config` where it would add data to
       config files that did not previously have them, or report that data was
       present in nonexistent config files.
     - Added the `releases` table to the databases. This table will keep track
       of releases of the Sqitch registry schema.
     - The Oracle `registry` variable is now always `DEFINE`d when Oracle
       scripts run.
     - Added the `upgrade` command, which upgrades the schema for the Sqitch
       registry for a target database.
     - Added the `script_hash` column to the `changes` registry table. This
       column contains a SHA-1 hash of the deploy script for the change at the
       time it was deployed. For existing registries, the upgrade script sets
       its value to be the same as the change ID. This value is update the
       next time a project is deployed to the database.
     - The error message when `deploy` cannot find the currently-deployed
       change ID in the plan now includes more contextual information,
       including the change name, associated tags, and the plan file name.
       Suggested by Curtis Poe (Issue #205).
     - Comments on Firebird registry objects are now created with the
       `COMMENT` command, rather than INSERTs into catalog tables.
     - Added support for "merge" events, though none are logged, yet.

0.997 2014-11-04T22:52:23Z
     [New Features]
     - Added support for new target properties. In addition to the existing
       `uri`, `client`, and `registry` properties, targets may also configure
       these properties via the new `--set` option to and `set-*` actions on
       the `target` command:
       * `top_dir`
       * `plan_file`
       * `extension`
       * `deploy_dir`
       * `revert_dir`
       * `verify_dir`
     - Added support for new engine configuration variables. In addition to
       the existing `target`, `client`, and `registry` variables, engine
       configuration may also include these variables:
       * `top_dir`
       * `plan_file`
       * `extension`
       * `deploy_dir`
       * `revert_dir`
       * `verify_dir`
     - Rationalized the hierarchical configuration of deployment targets. The
       properties of any given target will now be determined by examining
       values in the following order:
       * Command-line options
       * Target configuration
       * Engine configuration
       * Core configuration
       * Reasonable engine-specific defaults
     - Added the `engine` command to simplify engine configuration. This
       complements the newly-improved `target` command. Run `sqitch engine
       update-config` to update deprecated engine configurations and start
       using it.
     - Added the sqitch-configuration guide to provide an overview of core,
       engine, and target configuration. Includes some use-case examples and
       best suggested practices.
     [Improvements]
     - Simplified the output of `sqitch help`, and added the more important
       options to it.
     - Added the `--guide` option to `sqitch help` to list Sqitch guides.
     - Renamed the `--db-client` option to `--client`. `--db-client` still
       works, but is deprecated.
     - Added the `--registry` core option for parity with `--client`,
       `--top-dir`, `--plan-file`, and the rest of the hierarchical
       configuration properties.
     - Updated the `init` documentation to better cover all the options
       processed.
     - Incremented the version plan file format version to v1.0.0. No changes;
       it has been stable for at least a year, so it's time.
     [Bug Fixes]
     - At runtime, the Vertica engine now properly requires DBD::ODBC
       instead of DBD::Pg.
     - The Vertica engine now supports Vertica 6, as documented.
     - Fixed a warning from Type::Utils, thanks to a report from Géraud
       CONTINSOUZAS.
     - The `status` command once again notices if the specified database is
       uninitialized and says as much, rather than dying with an SQL error.
     - The `--etc-path` option works again.
     [Deprecations]
     - Deprecated `core.$engine` configuration in favor of `engine.$engine`. A
       warning will be emitted if Sqitch sees the former. Run `sqitch engine
       update-config` to update your configurations. Existing `core.$engine`
       configurations will be left in place for compatibility with older
       versions of Sqitch, but the `sqitch engine` command will not modify
       them, so they can get out-of-sync. Run `sqitch config --remove-section
       core.$engine` to remove them.
     - Formally deprecated the database connection options in favor of target
       URIs. If any of these options is used, a warning will be issued. They
       will be dropped in v1.0:
       * `--db-host`
       * `--db-port`
       * `--db-username`
       * `--db-password`
       * `--db-name`
     - Formally deprecated the database connection configuration variables in
       favor of target URIs. If any of these variables is used, a warning will
       be issued. Run `sqitch engine update-config` to update your
       configurations. Existing `core.$engine` configurations will be left in
       place for compatibility with older versions of Sqitch, but the `sqitch
       engine` command will not modify them, so they can get out-of-sync. Run
       `sqitch config --remove-section core.$engine` to remove them. Sqitch
       will cease to support them in v1.0:
       * `core.$engine.host`
       * `core.$engine.port`
       * `core.$engine.username`
       * `core.$engine.password`
       * `core.$engine.db_name`
     - Deprecated the `--registry` and `--client` options of the `target`
       command. All target properties should now be set via the new `--set`
       option, such as `--set registry=reg`.
     - Formally deprecated the following options of the `add` command. They
       have been replaced with the `--with`, `--without`, and `--use` options
       since v0.991. Their use will emit a warning, and they will be removed
       in v1.0:
       * `--deploy-template`
       * `--revert-template`
       * `--verify-template`
       * `--deploy`
       * `--no-deploy`
       * `--revert`
       * `--no-revert`
       * `--verify`
       * `--no-verify`
     - Dropped support for the long-deprecated (and likely never used outside
       ancient tests long deleted) engine configuration variables
       `core.sqlite.sqitch_db` and `core.pg.sqitch_schema`. Both have been
       replaced with `engine.$engine.registry`, which applies to all engines.
     - Formally deprecated the `@FIRST` and `@LAST` symbolic tags. Their use
       will trigger a warning to use `@ROOT` and `@HEAD`, instead. They will
       be removed in v1.0.
     [Internals]
     - Moved target and engine configuration from App::Sqitch and
       App::Sqitch::Engine to a new class, App::Sqitch::Target. This class is
       solely responsible for finding the appropriate values for attributes on
       every run. The target knows what plan and engine to use, based on those
       properties. App::Sqitch is now responsible solely for encapsulating
       command-line options, configuration, and utilities. Classes are now
       responsible for instantiating both an App::Sqitch and
       App::Sqitch::Target options as appropriate.
     - Updated all classes to create both Sqitch and Target objects as
       appropriate. This change touched almost every class.
     - Replaced attributes in App::Sqitch that were previously set from
       command-line options or configuration with a single attribute,
       `options`, which is a hash only of the command-line options. Classes
       are now responsible for finding the proper values in config or options.
       Mostly this requirement is encapsulated by the new App::Sqitch::Target
       class.
     - Updated the command classes to use either a "default target" derived
       from command-line options, engine configuration, and core
       configuration, or a target looked up by name in the configuration
       maintained by the `target` command.

0.996  2014-09-05T21:11:00Z
     - Fixed one more test failure due to the introduction of "Negative repeat
       count does nothing" warning in Perl 5.21.1.
     - Fixed "Redundant argument in printf" warning on Perl 5.21.2.
     - Switched from Digest::SHA1, which is deprecated, to Digest::SHA for
       generating SHA-1 IDs.
     - Switched from Mouse and Moose to Moo. Sqitch no longer depends on any
       modules that use Moose, either. This results in an approximately 40%
       startup time speedup.
     - Loading of App::Sqitch::DateTime is now deferred until it's needed.
       This is because DateTime is rather expensive to load. Since a number of
       commands don't need it, it seems silly to load it in those cases.
     - Now recommend Type::Tiny::XS and Class::XSAccessor for improved
       performance.
     - The `check` command now properly fails on a plan parse error, instead
       of blindly continuing on.
     - Fixed a failing test on PostgreSQL due to localization issues. Thanks
       to Sven Schoberf for the report (Issue #171).
     - Added the `revert.prompt_accept`, `rebase.prompt_accept`, and
       `checkout.prompt_accept` boolean configuration variables. Set these
       variables to false to change the default answer to the revert prompt to
       "No". When rebasing or checking out, if the variables specific to those
       commands are not set, Sqitch will fall back on the value of
       `revert.prompt_accept`. Suggested by Graeme Lawton (Issue #164).
     - The MySQL engine now sets the `$MYSQL_PWD` environment variable if a
       password is provided in a target. This should simplify authentication
       when running MySQL change scripts through the `mysql` client client
       (Issue #150).
     - The MySQL engine now reads `client` and `mysql` groups in the MySQL
       configuration files for a password when connecting to the registry
       database, and when the target URI includes no password. The MySQL

Changes  view on Meta::CPAN

     - Fixed test failures when the `$PGPASSWORD` environment variable is set,
       thanks to Ioan Rogers's test smoker.

0.990  2014-01-04T01:14:24Z
     [New Features]
     - Added new command and feature: `target`. Use it to manage multiple
       database targets, each with an associated URI and, optionally, a
       registry name and command-line client. Inspired by Git remotes.
     - Added Firebird engine. Three cheers to Ștefan Suciu for this
       contribution!
     - Added support for the generation of arbitrary scripts from templates to
       the `add` command. Just add template files to subdirectories of the
       `templates` directory, and scripts will be created in a directory of
       the same name based on those templates.
     - Added `--open-editor` option (and aliases) to the `add` and `rework`
       commands. This option will open the newly-added change scripts in the
       preferred editor. Thanks to Thomas Sibley for the patch!

     [Improvements]
     - Improved database driver loading to ensure the proper version of the
       driver is required.
     - Non-fatal but possibly unexpected messages -- which correspond to exit
       value 1 -- now send their messages to STDOUT instead of STDERR, and
       respect the `--quiet` option. Thanks to @giorgio-v for the report!
     - Added or replaced the `--target` option to commands that connect to a
       database to specify the name of target managed by the new `target`
       command or a database URI.
     - `HEAD` and `ROOT` are now recognized as aliases for `@HEAD` and
       `@ROOT`, respectively, since they are disallowed as change names,
       anyway, and folks often use them out of habit from Git.

     [Internals]
     - Replaced the engine-specific connection attributes with three
       attributes use by every engine:
       * `target`: The name of a target managed by the new `target` command.
         Defaults to a value stored for the `core.$engine.target`
         configuration variable. If that variable does not exist, the target
         falls back on the stringification of `uri`.
       * `uri`: a database URI with the format `db:{engine}:{dbname}` or
         `db:{engine}://{user}:{password}@{host}:{port}/{dbname}`. If its
         value is not passed to the constructor, a `uri` value is looked up
         for the associated `target`. If `target` is not passed or configured,
         or if it has no URI associated with it, the `config.$engine.uri`
         configuration variable is used. If that value does not exist, the URI
         defaults to `db:$engine:`. In any of these cases, if any of the
         `--db-*` options are passed, they will be merged into the URI.
       * `registry`: the name to use for the Sqitch registry schema or
         database, where Sqitch's own data will be stored, as appropriate to
         each engine. If its value is not passed to the constructor, a
         `registry` value is looked up for the associated `target`. If
         `target` is not passed or configured, or if it has no registry
         associated with it, the `config.$engine.registry` configuration
         variable is used. If no value is found there, it defaults to an
         engine-specific value, usually "sqitch".

     [Bug Fixes]
     - Fixed a bug when installing under local::lib. Thanks to Thomas Sibley
       for the pull request!
     - Eliminated "Wide character in print" warnings when piping the `log`
       command.
     - Documented that reworked changes do not have their verify tests run by
       the `verify` command. They do run when using the `--verify` deploy
       option.
     - Removed the documentation for the `add.with_deploy`, `add.with_revert`,
       and `add.with_verify` configuration variables, which were never
       implemented.

     [Deprecations]
     - Deprecated engine-specific connection attributes and configuration
       variables. See the "Internals" section for their replacements. The
       deprecated options are:
       * `core.$engine.username`
       * `core.$engine.password`
       * `core.$engine.db_name`
       * `core.$engine.host`
       * `core.$engine.port`
       * `core.$engine.sqitch_schema`
       * `core.$engine.sqitch_db`
     - Deprecated all command-specific options with the string "target" in
       them, such as `--to-target`, `--upto-target`, etc. They have been
       replaced with options containing the string "change", instead, such as
       `--to-change` and `--upto-change`. Few people used these options,
       preferring their shorter aliases (`--to`, `--upto`, etc.).
     - Deprecated the `--deploy-template`, `--revert-template`, and
       `--verify-template` options to the `add` command. They are replaced
       with a single option, `--use` which takes a key/value pair for the
       script name and template path. This makes it useful for arbitrary
       script generation, as well.
     - Deprecated the `--deploy`, `--revert`, and `--verify` options to the
       `add` command, as well as their `--no-*` variants. They are replaced
       with two new options, `--with` and `--without`, to which a script name
       is passed. These are useful for arbitrary script generation, as well.
     - Deprecated the `add.deploy_template`, `add.revert_template`, and
       `add.verify_template` configuration settings. They have been replaced
       with a section, `add.templates`, which is more general, and supports
       arbitrary script generation, as well.

     [Incompatibilities]
     - Removed the undocumented `--test` option to the `add` command.
     - Changed the meaning of `--target` from specifying a change to
       specifying a deployment target. Use the new `--change` option to
       specify a change.

     - Fixed "Use of uninitialized value" in the MySQL engine. Thanks to
       Jean-Michel REY for the report.
     - All tests now protect against failures due to the presence of the
       `$SQITCH_CONFIG` environment variable (issue #114).
     - The installer now respects the `distdir` option to `Build.PL` when
       searching for existing templates. Important for packaging.
     - Fixed the error "Table 'sqitch.changes' doesn't exist" when deploying
       to a MySQL database that exists but has not been initialized. Thanks to
       Jean-Michel REY for the report!
     - Refactored the handling of the C<--log-only> option so it sets an
       engine attribute, rather than passing the flag to a whole stack of
       method calls.
     - Fixed "Argument "en_us" isn't numeric" error on Windows.
     - Now using `LC_ALL` instead of `LC_MESSAGES` when setting the locale, as
       the latter is not present on Windows.
     - The sqitch-pg RPM now requires DBD::Pg 2.0.0 or higher.
     - Improved handling of invalid command names so that the error message is
       less ambiguous when triggered by a Perl parse error.
     - Added `-m` as an alias for `--note`, for you Git folks out there.
     - Added exception handling to the Postgres and Oracle engines to avoid
       unexpected errors when deploying to a database that has not been
       deployed to before.
     - Updated detection of an uninitialized database to double-check with the
       engine that it really thinks it's uninitialized, not just that the
       "changes" table is missing. This should catch the case where the
       database has its own "changes" table unrelated to Sqitch.

0.982  2013-09-11T18:26:07Z
     - Errors thrown by Template toolkit are no longer silently ignored.
     - Variables passed to change templates are now cloned before the
       execution of each template. This prevents one template from deleting
       variable values another template might also need.
     - Fixed "The getpwnam function is unimplemented" errors on Win32.
     - No longer runs revert scripts when deploying with `--log-only` and a
       verify script fails, as that could lead to data loss (yikes!). Thanks
       to BryLo for the report (issue #112).

0.981  2013-09-06T00:22:26Z
     - Now use Encode::Locale to try to decode the user's full name from the
       system encoding when fetched from the system on all OSes. Note that
       this is not necessary if the `user.name` config is explicitly set, as
       recommended. Issue #107.
     - Removed the special-case handling of the user's full name fetched from
       the system on OS X.
     - Added call to `sleep` to test in an attempt to fix SQLite failures.
     - The SQLite engine now requires that the SQLite client be 3.3.9 or
       later, for support of the `-bail` option.
     - Bug fix: The MySQL engine now properly uses the host, port, and
       password options when connecting to the database. Thanks to vreb87 for
       the report!

0.980  2013-08-28T21:40:00Z
     - Changed the default SQLite Sqitch database name from
       `$dbname-sqitch.$suffix` to `sqitch.$suffix`. The `$suffix` still
       comes from the destination database name. This breaks compatibility
       with previous releases. If you need the old name, set it with
       `sqitch config core.sqlite.sqitch_db $dbname`.
     - Fixed encoding of the user's full name when fetched from the system on
       OS X. Thanks to Tomohiro Hosaka for the pull request!
     - Fixed test failures when DBD::SQLite is installed but compiled with
       SQLite 3.7.10 or lower.
     - Fixed a bug where declaring a dependency on a reworked change would
       incorrectly result in the error "Key "foo" matches multiple changes".
       Thanks to BryLo for the report (issue #103).
     - Modified tests to allow them to run in parallel without stomping on
       each other.
     - Bundling of options, such as `-vvv`, now works properly (issue #108).
     - Added alias `--get-regexp` for `--get-regex` to the `config` command.
       This brings it in line with the documentation for the `config` command
       (Issue #110).
     - Fixed all of the `config` command actions that contain a dash so that
       they actually work. Thanks to Ștefan Suciu for the report (issue #110).
     - All leading and trailing white space is now trimmed from plan notes,
       rather than just vertical white space. Thanks to Ronan Dunklau for the
       report (issue #106).
     - The `status` command now notices if the specified database is
       uninitialized and says as much, rather than dying with an SQL error
       (issue #109).
     - When reading the user's username from the system Sqitch now uses
       Encode::Locale to try to decode the value from the system encoding.
       Issue #107.
     - Compatibility change: Changed the location and name of script template
       files. Previously they were called `deploy.tmpl`, `revert.tmpl`, and
       `verify.tmpl`, and they lived in the `templates` subdirectory of the
       system-wide and user-specific configuration directories. They now live
       in subdirectories of the `templates` directory named for each action
       (deploy, revert, and verify), and with file names matching engine names
       (`pg.tmpl`, `sqlite.tmpl`, `oracle.tmpl`, and `mysql.tmpl`). The
       installer will move old files from the system-wide config directory
       (`sqitch --etc-path`) to their new homes, named `pg.tmpl` and
       `sqlite.tmpl`. It assumes no customizations exist for Oracle. If that's
       not true in your case, simply copy the `pg.tmpl` files to
       `oracle.tmpl`.
     - Added the `--template-name` option to the `add` command. By default, it
       looks for templates named for the current engine. The option allows for
       the user of task-specific templates. For example, if you create
       templates named `createtable.tmpl` in the `deploy`, `revert`, and
       `verify` subdirectories of `~/.sqitch/templates`, You can specify
       `--template-name createtable` to use those templates when adding a
       change.
     - Added the `--exists` option to the `show` command.
     - Fixed the `--set` option to the `add` command so that duplicate keys
       have their values passed to the template as an array, as documented.
     - If Template::Toolkit is installed, the `add` command will use it for
       processing templates instead of Template::Tiny. This makes it easy to
       upgrade the templating environment just by installing a module.

0.973  2013-07-03T13:47:22Z
     - Now Require DBD::SQLite compiled with SQLite 3.7.11 or higher. It
       always has, but now it throws a meaningful exception if an older
       version is compiled into DBD::SQLite. Thanks to Damon Buckwalter for
       the report.
     - When a deploy fails because of missing dependencies, the list of
       missing dependencies no longer contains duplicates. Thanks to Damon
       Buckwalter for the report.

0.972  2013-05-31T23:26:52Z
     - Fixed test failures on Windows.
     - Fixed locale configuration on Windows so that `sqitch` will actually
       run, rather than exiting with an error about `LC_MESSAGES` not being
       set.
     - Fixed a test hang on Windows when DBD::Oracle is installed but the
       Oracle libraries (`OCI.dll`) are not or cannot be found. This was
       triggering a UI dialog that did not dismiss itself. Using Win32::API
       to work around this issue. Thanks to Jan Dubois for the fix.

0.971  2013-05-18T21:08:51Z
     - Removed most uses of the smartmatch operator, since as of Perl 5.17.11
       it is marked as experimental, and silenced the warning where it is
       still used.
     - Added 0.1s sleep between logging changes back-to-back in the engine
       tests, mostly to try to get SQLite to generate different timestamps.
       Pretty sure the recent test failures have been due to the passage of
       less than a millisecond between the two inserts.
     - Added the `shell` and `quote_shell` methods to Sqitch.pm for shelling
       out a command.
     - Sqitch now shells out to an editor when opening a file for the user to
       edit. For example, if the `$EDITOR` environment variable is set to
       `"emacs -nw"`, it will now work. Thanks to Florian Ragwitz for the
       report (issue #80).
     - Removed the pod-checking tests from the distribution.

0.970 2013-05-09T00:21:06Z
     - Fixed the default ordering of changes displayed by the `plan` command.
       They are now ascending by default.
     - Switched to PerlIO::utf8_strict for fast character encoding and
       decoding.
     - The help emitted when an unknown option is passed to `sqitch` now
       consists of a usage statement and brief table of options, rather than
       the entire man page.
     - Added the project name in a header to the output of the `plan` command.
     - Added the Oracle engine.
     - Added `sqitchtutorial-oracle.pod`, a Oracle-specific variant of
       `sqitchtutorial.pod`.
     - Added missing version declaration to the App::Sqitch::Plan::* modules.
     - Devel::StackTrace 1.30 is now properly required (it was previously
       recommended).
     - The `--show-tags` and `--show-changes` options to the `status` command

Changes  view on Meta::CPAN

     - Fixed the loading of the editor with placeholder text to properly
       encode that text as UTF-8 (Ronan Dunklau).

0.961  2013-04-09T19:21:15Z
     - Fixed error when running on PostgreSQL 9.0.
     - Added support for PostgreSQL 8.4.
     - Fixed the SQLite tests to skip the live tests when `sqlite3` cannot be
       found.
     - Fixed the Postgres tests to skip the live tests if `psql` cannot be
       found or cannot connect to the database.
     - Fixed the `checkout` test to skip tests that depend on Git and Git is
       not found in the path.
     - Fixed test failures on Windows (hopefully).
     - Made the order of commented configuration variables in the project
       configuration file deterministic. It will now always be the same order
       as specified by the engine class. This fixes test failures on Perl
       5.17.
     - Fixed encoding issue that caused test failures on Perl 5.17.
     - Requiring Devel::StackTrace 1.30, as earlier versions can
       intermittently suppress errors.
     - Added hack to `App::Sqitch::X::hurl()` to work around a bug in
       Throwable that prevents `previous_exception` from being set half the
       time on v5.17.

0.960  2013-04-05T23:04:35Z
     - Removed `-CAS` from the shebang line on Perl 5.10.0. This is to
       eliminate `Too late for "-CAS" option` errors. This means that UTF-8
       semantics will be suboptimal on Perl 5.10.0. Consider upgrading to 5.12
       or higher.
     - Added the `checkout` command. Pass it the name of a VCS branch, and it
       will compare the plans between that branch and the current branch,
       revert to the last common change, check out the branch, and then
       redeploy. This makes it easy to switch between working branches that
       have different sets of commits. Git-only for now. Idea and code by
       Ronan Dunklau.
     - The `rebase` command no longer fails if the database is already
       reverted, but just makes a note of it and goes on to the deploy.
     - Added the `plan` command. It's like `log`, but shows a list of changes
       in the plan, rather than events recorded in the database.
     - Added `search_changes()` to Plan. Used by the `plan` command.
     - Added the `--oneline` option to the `log` command.
     - Allow tagging of an arbitrary change, not just the last change in the
       plan, by passing a change specification (name, ID, or tag) as the
       second argument to the `tag` command.
     - Updated error messages to note that blank characters are not allowed in
       project, change, or tag names.
     - Factored most of the engine-specific code into
       App::Sqitch::Role::DBIEngine. Future DBI-based engines should be able
       to use this role to handle most of the work.
     - Factored the live engine tests int `t/lib/DBIEngineTest`. Future
       DBI-based engines can use this module to do all or most of the live
       testing.
     - Added the SQLite engine. The Sqitch metadata is stored in a separate
       file from a database, by default in the same directory as the database
       file.
     - Added `sqitchtutorial-sqlite.pod`, a SQLite-specific variant of
       `sqitchtutorial.pod`.

0.953  2013-02-21T23:37:57Z
     - Fixed test failure in `t/engine.t` triggered by a clock tick.
     - Changed the verify template to end with `ROLLBACK` rather than
       `COMMIT`. This it to encourage folks to make no lasting changes in
       verify tests.
     - Fixed exception triggered on an attempt to revert or rebase `--to` a
       change that does not exist in the database.
     - Added recommendation for Pod::Simple to the build process.
     - Added the `--etcdir` build option to specify the directory in which
       configuration and template files should be installed. Defaults to the
       `etc/sqitch` subdirectory of the `--prefix`, `--install_base`, or
       Perl's prefix.
     - Added the `--installed_etcdir` build option. This is used to set
       the location of the system etc directory. Defaults to the value of
       `--etcdir`.
     - When building with `--prefix` or `--install_base`, and without
       `--etcdir`, the configuration files and tmeplates are now installed
       into `etc/sqitch` in that directory, rather than just `etc`. This is to
       enable packaging systems to move the directory to the proper location.

0.952  2013-01-12T00:02:54Z
     - Switched from Moose to Mouse whever possible. Speeds load and runtime
       20-30%. Thanks to Michael Schwern for the pull request!

0.951  2013-01-08T00:21:58Z
     - Fixed double "@" displayed for tags in the output of `revert`.
     - Fixed reversion of reworked changes to run the original revert script,
       rather than the reworked script.
     - Added `is_reworked` accessor to App::Sqitch::Plan::Change.
     - Changed the behavior determining the file name to use for reworked
       change scripts. It now looks for a deploy script using the name of any
       tag between the reworked instances of a change and selects the first
       one it finds that exists. This will allow Sqitch to find the proper
       script name even if new tags have been added to the plan (issue #70).

0.950  2013-01-03T23:09:42Z
     - Fixed the "Name" header in `sqitch-rebase` so that it will actually
       show up on the CPAN search sites.
     - Fixed test failure triggered by the passage of time in `t/engine.t`.
     - At the start of a `deploy`, if the most recently deployed change has
       any unlogged tags (that is, tags added since the last `deploy`), they
       will be logged before the `deploy` continues (issue #60).
     - Added the `--no-log` option to `deploy`, `revert`, and `rebase`. This
       causes the changes to be logged as deployed without actually running
       the deploy scripts. Useful for an existing database that is being
       converted to Sqitch, and you need to log changes as deployed because
       they have been deployed by other means in the past.
     - Now check that dependencies are required for all changes to be deployed
       or reverted before deploying or reverting anything, rather than
       checking dependencies for each change just before deploying or reverting
       it. This allows a or revert deploy to fail sooner, with no database
       changes, when dependencies are not met.
     - The `deploy` command now checks that no changes its about to deploy are
       already deployed.
     - Added `--mode` to the `rebase` command.
     - Added the `--verify` option to `deploy` and `rebase`. Specify this
       option to run the verify script, if it exists, for each change after it
       is deployed. If the verify script dies, the deploy will be considered a
       failure and the requisite reversion (as specified for `--mode`) will
       begin.
     - Added the `verify` command, which verifies that a database is valid
       relative to the plan and each deployed change's verification scripts.
     - Changed the format of the list of changes output by `deploy` and
       `revert` so that each now gets "ok" or "not ok" printed on success or
       failure.
     - Added short aliases for commonly-used core options:
       * -f for --plan-file
       * -v for --verbose
       * -h for --db-host
       * -p for --db-port

0.940  2012-12-04T05:49:45Z
     - Fixed tests that failed due to I18N issues, with thanks to Arnaud
       (Arhuman) ASSAD!
     - Localized messages are now properly encoded in UTF-8. Thanks to Ronan
       Dunklau for the report (issue #46) and to Guido Flohr for details on
       how to address the issue.
     - The variables defined for the `add`, `deploy`, and `revert` commands
       now have the case of there names preserved if Config::GitLike 1.10 or
       later is installed. Thanks to Ronan Dunklau for the report (issue #48)
       and to Alex Vandiver for the case-preserving update to Config::GitLike.
     - Attempting to run `sqitch` with no command now outputs the list of
       supported commands (`sqitchcommands`), rather than the list of core
       options. Thanks to BryLo for the suggestion.
     - Changed the plan parser so that it no longer changes the order of
       changes based on the dependency graph. Unfortunately, this meant that
       the order could change from one run to another, especially if new
       changes were added since the last deploy. The planner now throws an
       exception if the order in the plan is wrong, and suggests that the user
       move changes in the plan file to get it to work properly.
     - Fixed bug where the `core.plan_file` configuration variable was
       ignored.
     - Improved error handling when deploying and reverting a change. If the
       change successfully deployed but the logging of the deployment to the
       database failed, there was just a rollback message. Sqitch will now
       emit the underlying error *and* run the revert script for the
       just-deployed change.
     - Modified the text hashed for change and tag IDs. Both now include the
       note, if present, the ID of the preceding change, and the list of
       dependencies. The result is that, when a change is modified or moved in
       the plan, it gets a new ID ID. The upshot is that things *must* be in
       order for a deploy to succeed. Existing deployments will automatically
       have their IDs updated by the `deploy` command.
     - Changed the `revert` command so that it *only* fetches information about
       changes to be reverted from the database, rather than the plan.
     - Deprecated the `@LAST` and `@FIRST` symbolic tags. With `revert` now
       fetching change information from the database, there is no longer a
       need to specify that changes be found in the database. It's possible
       some other way to search database changes will be added in the future,
       but if so, it will be less limiting than `@LAST` and `@FIRST`, because
       it will likely allow searches by literal tags.
     - Added the `rebase` command. This command combines a `revert` and a
       `deploy` into a single command, which should allow for more natural
       deployment testing during development. `sqitch rebase @HEAD^` should
       become a common command for database developers.
     - Duplicate values passed via `--requires` and `--conflicts` in the `add`
       and `rework` actions are now ignored.
     - The `add` command now throws an exception if `--template-directory` is
       passed or specified in the configuration file, and the specified
       directory does not exist or is not a directory. Thanks to Ronan Dunklau
       for the report! (Issue #52).
     - The `revert` command now prompts for confirmation before reverting
       anything. The prompt can be skipped via the `-y` option or setting the
       `revert.no_prompt` configuration variable. Works for rebase, too, which
       reads `rebase.no_prompt` before `revert.no_prompt`.' (Issue #49.)
     - Added the `show` command, which show information about changes or tags,
       or the contents of change script files. (Issue #57.)
     - Renamed the `test` scripts and planned command to `verify`.

0.938 2012-10-12T19:16:57Z
     - Added a primary key to the PostgreSQL `events` table, which should make
       it easier to support replication.

0.937 2012-10-09T21:54:36Z
     - Fixed the `--to` option to `deploy` and `revert`, which was ignored
       starting in v0.936.

0.936 2012-10-09T19:11:5Z2
     - Added `--set` option to the `deploy` and `revert` commands. Useful for
       setting database client variables for use in scripts. Used by the
       PostgreSQL engine.
     - Merged the contents of `dist/sqitch-pg.spec` into a subpackage in
       `sqitch.spec`. This allows both RPMs are created from a single build
       process. Simplifies things quite a bit and improves the flexibility for
       adding other engines in the future.
     - Reduced required Perl version from 5.10.1 to 5.10.0.
     - Fixed inconsistent handling of command options with dashes where some
       were ignored.
     - The bundle command now properly copies scripts for changes with slashes
       in their names -- that is, where the scripts are in subdirectories.

0.935 2012-10-02T19:21:05Z
     - Updated `dist/sqitch-pg.spec` to require `postgresql` rather than
       "postgresql91". The version doesn't matter so much.
     - All known Windows issues and failures fixed, with many thanks to Randy
       Stauner for repeatedly running tests and supplying patches:
       - Fixed "'2' is not recognized as an internal or external command,
         operable program or batch file" error on Windows.
       - Fixed multiple errors detecting Windows. The OS name is "MSWin32",
         not "Win32". The test failure thus addressed was the setting of the
         DateTime locale.
       - Fixed failing tests that were incorrectly comparing subprocess errors
         messages on Windows
       - Fixed bug in `bundle` where a file would be re-copied even if the
         source and destination had the same timestamps, as they seem to do
         during tests on Windows. Patch from Randy Stauner.
       - Fixed failing test that failed to include `.exe` in a file name on
         Windows. Patch from Randy Stauner.
     - Added French translation, with thanks to Arnaud (Arhuman) ASSAD!

0.934 2012-09-28T16:43:43Z
     - Fixed typo in error handling that prevented an I/O error message from
