 Revision history for Perl extension Coro.
 
-2.1
-TODO: aioreq_pri etc.
+TODO: better (earlier) error messages on broken transfer's
+TODO: destroy gets only called on cancel: fix(?)
+
+	- remove t/09_timer.t, as it isn't really testing much
+          but was rather flaky in practise.
+
+3.3  Sat Jan  6 03:45:00 CET 2007
+	- implement $coro->on_destroy.
+        - Coro::Event blocking semantics have been changed,
+          documented and - hopefully - improved.
+	- fix nice adding, not subtracting, from priority.
+        - fix ->prio and api_is_ready (patch by Mark Hinds).
+        - fixed an assert ("... == prev__cctx->idle_te")
+          that could errronously trigger.
+        - fix various large and small memleaks.
+        - use a (hopefully) more stable cancel implementation
+          that immediately frees the coroutine data.
+        - cede/cede_notself return a status now.
+        - added Coro::guard function.
+        - added a global coroutine pool for jobs (on my machine,
+          I can create and execute 48k simple coros/s with async,
+          and 128k coros with async_pool).
+        - Coro::AIO now uses the coroutine priority as io priority.
+
+3.2  Fri Dec 22 05:07:09 CET 2006
+	- improve portability to slightly older perls.
+        - use cleaner coroutine destruction.
+        - simplify configuration for users.
+        - optionally (unrecommended) prefer perl functions over
+          their coro replacements.
+
+3.11 Tue Dec  5 13:11:24 CET 2006
+        - fixed some bogus assert's, but as perl.h disables assert even
+          without NDEBUG (thank you very much), not too many people should
+          notice (that did include myself). Andreas König noticed, though :)
+	- do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
+          it. Also noticed by Andreas König :)
+        - save/restore tainted status.
+        - verified to pass the testsuite on my 5.9.5.
+
+3.1  Mon Dec  4 23:03:40 CET 2006
+        - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
+        - incompatible change: transfer flags are now per-state.
+	- give a better error message on deadlock.
+        - document Coro::nready.
+        - enhanced testsuite.
+
+3.01 Sun Dec  3 23:47:42 CET 2006
+	- forgot to include Coro::Timer.
+
+3.0  Sun Dec  3 22:57:25 CET 2006
+	- the "FINALLY COMPLETELY STABLE" release (coming soon:
+          the "FAMOUS LAST WORDS" release).
+	- implement a new stack sharing algorithm, which uses a stack
+          pool (size currently hardcoded).
+        - make stack sharing mandatory (it no longer uses a heuristic).
+        - eval/die no longer cause weird problems under heavy use.
+        - Coro::Event could cause livelocks if it was used but
+          no Coro::Event watchers were used.
+        - Coro::Event now uses asynccheck as prepare does not
+          check for changed watchers.
+        - Coro::Event allows multiple waiting coros and will wake up one
+          per event.
+        - Coro::Event should be cleaner and more efficient now.
+        - new utility function Coro::unblock_sub.
+        - document the sad fact that Event is no longer reentrant.
+        - putting a coroutine into the ready queue twice could under
+          some circumstances lead to stack corruption.
+        - minor incompatibility: subclassing Coro::State is supported
+          directly now without going through a _coro_state member.
+        - state/coro switching is much faster now.
+        - very minor optimisations and code/documentation cleanup.
+        - avoid problems due to compiler inlining.
+        - removed timers from Coro::Timer -> use AnyEvent instead.
+        - replaced Coro::idle coroutine by (cleaner) idle handler.
+        - updated to newest libcoro.
+        - implement enhanced support for valgrind.
+        - implement is_ready and return value for ready.
+        - removed Coro::Cont, it was a misnomer (it's generators),
+          and it was somewhat annoying to get it right. Will come back
+          if somebody asks for it :)
+        - many ->wait methods and Coro::Event could return
+          spuriously without the event having happened.
+
+2.5  Tue Nov  7 12:22:33 CET 2006
+        - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
+          use AnyEvent, moved them to Coro/.
+	- added Coro::LWP which contains all the uglyness required to
+          make LWP non-blocking.
+	- should work with perl 5.9.x now (Andreas König made me do it).
+        - fixed another bug in Coro::Select when the timeout was undef.
+        - reuse PL_start_env for all coros, saves some memory per coroutine.
+        - manage PL_top_env differently, hopefully to avoid panic: top_env.
+        - timeout argument was not properly used in Coro::Socket.
+        - allow limited forms of subclassing in Coro::Handle/Coro::Socket.
+        - emulate undocumented(!) functionality of IO::Socket required
+          by LWP(!!).
+        - updated eg/lwp to work with newer lwp's.
+        - remove "FATAL: uncaught exception" prefix. Coroutines that die
+          kill the whole process, just as exceptions in the main "coroutine"
+          did already.
+
+2.1  Wed Nov  1 23:01:13 CET 2006
+        - fix a long-standing bug in Coro::Select where select with
+          zero timeout would instead change the current default filehandle.
 	- use a simpler and hopefully more robust way to clone padlists
           (uses less memory and a perl function instead of our own).
         - coro can now create a stack guard area on many architectures.
+        - Coro::AIO properly reexports additional functions from IO::AIO.
 	- updated libcoro with a workaround for OS X,
-          pach by Michael Schwern.
-        - fix a long-standing bug in Coro::Select where select with
-          zero timeout would instead change the current default filehandle.
+          pach and testing by Michael Schwern.
 
 2.0  Tue Oct 24 05:47:17 CEST 2006
 	- support additional aio requests in Coro::AIO.
