 Revision history for Perl extension Coro.
 
-TODO: check wether stack-sharing is still effective
-TODO: more effective stack sharing by having one "default stack" for "simple" coroutines?
-TODO: verify exception frame changes and force stack copies?
+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.
+        - async_pool coro would keep arguments and callback alive until
+          it was reused.
+        - cancellation of a coroutine could cause spurious idle calls
+          in cede_notself.
+
+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
-          Event watchers were used directly.
+          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.
-	- minor documentation cleanup.
-        - very minor optimisations and cleanups.
+        - 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
