        - use more workarounds around the many refcnt/corruption bugs in
          Event::Lib.
        - work around a race condition in perl's select, causing t/03_child.t
          to rarely fail.

4.81 Thu Jul  9 10:30:30 CEST 2009
        - AnyEvent::Handle didn't properly diagnose write errors
          (it expected -1 from syswrite, how lame... :).
	- support file descriptors in addition to file handles
          in AnyEvent->io.
	- new env variables: PERL_ANYEVENT_RESOLV_CONF,
          PERL_ANYEVENT_MAX_OUTSTANDING_DNS, PERL_ANYEVENT_CA_FILE
          and PERL_ANYEVENT_CA_PATH.
        - provide a sensible synopsis section for AnyEvent::TLS.
        - add a "supported backends" section to the manpage.
        - added simple io watcher test to testsuite, using a
          portable_socketpair.
        - tried to improve the stability of the Event::Lib backend,
          YMMV.

4.8  Mon Jul  6 23:45:16 CEST 2009
	- AnyEvent::DNS did not properly follow CNAME records with
          uppercase targets.
        - AnyEvent::DNS would errornously return AAAA records
          with v4 mapped addresses (a faulty record) as ipv4 addresses,
          causing AnyEvent::Socket to throw an exception.
        - added new module AnyEvent::TLS for easier SSL/TLS context
          creation, with many options including hostname verification,
          secure default configuration, lots of documentation and,
          predefined diffie-hellman keys for perfect forward security
          and much more. get it while it's still fresh!
        - use AnyEvent::TLS in AnyEvent::Handle for context management.
	- load AnyEvent::Handle only on demand in AnyEvent::DNS,
          so AnyEvent::Socket users have smaller memory footprint
          in the common case.
        - add AnyEvent::Handle->push_shutdown method.
        - add an additional error message parameter to AnyEvent::Handle's
          on_error callback (for TLS, $! is still available).
        - add AnyEvent::Handle on_starttls/on_stoptls callbacks.
        - make AnyEvent::Handle more robust against early connection
          failures (during new), and return C<undef> in that case
          from the constructor.
        - AnyEvent::Handle will now try to load only JSON::XS first,
          then fall back to JSON.
        - format_ipv4/format_ipv6 are now exported by default, for symmetry,
          and because it was documented that way.

4.451 Fri Jul  3 00:28:58 CEST 2009
	- do not clear rbuf when shutting down an AnyEvent::Handle
          object - doing so breaks AnyEvent::HTTP.

4.45  Mon Jun 29 22:59:26 CEST 2009
        - a write error could cause AnyEvent::Handle to create
          an I/O watcher with an undefined $fh.
        - special-case mapped ipv4 addresses in both
          AnyEvent::Socket::format_address and parse_address,
          to treat them just like ipv4 addresses.
        - updated and overhauled the AnyEvent::Intro doc.
        - implement AnyEvent::Socket::format_ipv4/ipv6.
	- slightly speed up portable_pipe/socketpair.
        - expand condvar begin/end documentation.

4.42  Fri Jun 26 08:32:18 CEST 2009
	- preliminary and neccesarily incomplete support for IO::Async.
	- reset SIGCHLD to DEFAULT when AnyEvent is loaded, in
          case it was set to IGNORE, to ensure we can catch child statuses
          even when the calling env acts stupidly.
        - updated benchmarks with IO::Async, which performs very well.

4.412 Wed Jun 24 01:35:57 CEST 2009
	- support an "untaint" attribute for AnyEvent::DNS
          and set it on the default resolver.
	- implement and document AnyEvent::Impl::Perl::loop.
        - remove all anyevent-env variables from %ENV
          when running in tainted mode.
        - mention and extend the IO::Lambda benchmark.

4.411 Sun Jun  7 18:48:02 CEST 2009
	- do not try to use F_SETFD on windows.

4.41  Thu May 14 06:40:11 CEST 2009
        - work around issues in older perls (5.8.0?) when
          a signal handler is deleted from the %SIG hash.
        - use POSIX::_exit in child test, to avoid running
          destructors.
        - speed up CHLD handling by relying on SIGCHLD being
          synchronously delivered, even when we roll our own
          implementation.
	- AnyEvent::DNS: add the "dname" resource record name
          for cosmetic reasons.

4.4   Sun Apr 26 20:12:33 CEST 2009
	- implemented idle watchers, where applicable.
	- AnyEvent->time died when Event backend was in use.
        - fix a memleak in the Tk backend.
        - sped up Tk timer handling.
        - clip negative "after" values to 0 in AnyEvent::Impl::Event
          to avoid spamming out warning messages.
        - fix Qt timers without interval.
        - avoid Qt zero-timeout special case, in old libqt's.

4.352 Mon Apr 20 16:31:11 CEST 2009
	- fix AnyEvent::Strict error messages for child watchers.
        - fix/update Makefile.PL "recommends" versions.
        - add AnyEvent->now_update.

4.351 Sat Apr 11 07:56:14 CEST 2009
        - actually make the signal pipe work under win32.
        - localise $! in signal handler to avoid changing $!, although
          perl itself does not seem to save/restore errno either.
	- set the cloexec flag on the signal pipe (normally set by perl too).

4.35  Fri Mar 27 11:48:20 CET 2009
        - event models relying on AnyEvent's signal watcher emulation did
          invoke the callback asynchronously, contradicting documentation
          and causing signals to get lost (this includes AnyEvent's own
          event loop). AnyEvent now uses the standard pipe trick to make
          callback execution synchronous to the event loop.
        - AnyEvent::Handle didn't free TLS context data on DESTROY
          (patch by Pavel Shaydo).
        - work around the ever-incompatibly-changing API of MakeMaker.
