        - praise the joys of AnyEvent::Fork::*.
        - time for an =encoding directive.
        - do no longer use JSON to create a default json coder, use
          JSON::XS or JSON::PP directly.

	- uts46data.pl couldn't be found due to wrong naming of the file
          (reported by Fulko Hew).
        - handle lone \015's properly in AE::Handle's default line read
          (reported by various people).
        - untaint ip addresses found in /etc/hosts (patch by José Micó).
        - the memleak fix in 7.03 caused resolving via /etc/hosts to always
          fail on first use (reported and testcase by Andrew Whatson).
        - expose AnyEvent::Log::format_time, and allow users to redefine it.
        - expose AnyEvent::Log::default_format, and allow redefinition.
        - expose AnyEvent::Log::fatal_exit, to allow redefinition.
	- AnyEvent::Debug shell can now run coro shell commands, if available.
	- t/63* tests were wrongly in MANIFEST.
        - kernel.org's finger server went MIA, switch to freebsd.org and
          icculus.org.
        - clarify that IO::AIO and AnyEvent::AIO are needed for AnyEvent::IO

    should not access env variables starting with "AE_", see below).

    All variables can also be set via the "AE_" prefix, that is, instead of
    setting "PERL_ANYEVENT_VERBOSE" you can also set "AE_VERBOSE". In case
    there is a clash btween anyevent and another program that uses
    "AE_something" you can set the corresponding "PERL_ANYEVENT_something"
    variable to the empty string, as those variables take precedence.

    When AnyEvent is first loaded, it copies all "AE_xxx" env variables to
    their "PERL_ANYEVENT_xxx" counterpart unless that variable already
    exists. If taint mode is on, then AnyEvent will remove *all* environment
    variables starting with "PERL_ANYEVENT_" from %ENV (or replace them with
    "undef" or the empty string, if the corresaponding "AE_" variable is
    set).

    The exact algorithm is currently:

       1. if taint mode enabled, delete all PERL_ANYEVENT_xyz variables from %ENV
       2. copy over AE_xyz to PERL_ANYEVENT_xyz unless the latter alraedy exists
       3. if taint mode enabled, set all PERL_ANYEVENT_xyz variables to undef.

    This ensures that child processes will not see the "AE_" variables.

    The following environment variables are currently known to AnyEvent:

    "PERL_ANYEVENT_VERBOSE"
        By default, AnyEvent will log messages with loglevel 4 ("error") or
        higher (see AnyEvent::Log). You can set this environment variable to
        a numerical loglevel to make AnyEvent more (or less) talkative.

is used by AnyEvent itself as well.

It only ever creates one resolver and returns this one on subsequent calls
- see C<$AnyEvent::DNS::RESOLVER>, below, for details.

Unless you have special needs, prefer this function over creating your own
resolver object.

The resolver is created with the following parameters:

   untaint          enabled
   max_outstanding  $ENV{PERL_ANYEVENT_MAX_OUTSTANDING_DNS} (default 10)

C<os_config> will be used for OS-specific configuration, unless
C<$ENV{PERL_ANYEVENT_RESOLV_CONF}> is specified, in which case that file
gets parsed.

=item $AnyEvent::DNS::RESOLVER

This variable stores the default resolver returned by
C<AnyEvent::DNS::resolver>, or C<undef> when the default resolver hasn't
