8	5.0	10	- speed up ready queue management/contetx switching by using a linked
		11	list instead of an array (~5-10%).
		12
		13	5.132 Fri May 29 09:00:39 CEST 2009
		14	- do not keep a reference to the argument itself in
		15	Coro::Semaphore::guard, as it could change later.
		16	- support SO_RCVBUF/SO_SNDBUF nonstandard Coro::Socket options,
		17	should support a prepare callback.
		18
		19	5.131 Mon Mar 16 23:20:37 CET 2009
		20	- implement and document Coro->suspend, Coro->resume.
		21	- fix Coro::Select implementation to not (often) close
		22	the passed file descriptors (testcase provided by pippijn).
		23
		24	5.13 Mon Dec 15 21:51:42 CET 2008
		25	- EXPERIMENTAL: implement dynamic winds (on_enter/on_leave).
		26	- don't set diehook to C<undef> but instead to NULL, to avoid
		27	spurious warnings.
		28	- fix a lot of bugs in Coro::SemaphoreSet.
		29	- Coro::SemaphoreSet will less often create a semaphore needlessly.
		30	- add Coro::SemaphoreSet::count and wait methods.
		31	- take advantage of the new Guard module.
		32	- deprecate Coro::guard.
		33	- try to fix the dreaded 01_unblock tests once more. I hate it when
		34	testsuites need more fixing than the code they are supposed to test.
		35	- croak in more cases when a required callback isn't resolvable.
		36	- fix some minor issues in Coro::State->call/eval.
		37	- use current coroutine context instead of a temporary one
		38	when temporarily switching to another coroutine.
		39	- do not call C-level on_destroy handlers during global destruction,
		40	to avoid needless segfaults.
		41
		42	5.12 Sun Dec 7 13:30:38 CET 2008
		43	- add default config for MirOS, which seems to be a bug-to-bug
		44	compatible fork of openbsd ("world domination by releasing
		45	openbsd cvs before the openbsd folks do it" or so :).
		46	- free_padlist did destroy the names pad, not good, but didn't
		47	seem to bother perl - this could fix issues such as eval ""
		48	inside a function called from multiple coroutines.
		49	- use a different method to detect destruction time.
		50	- be more careful when freeing padlists just before global
		51	destruction.
		52	- fixed and expanded the call/cc example.
		53	- renamed _terminate to _coro_run.
		54	- new method Coro::Channel->shutdown.
		55	- try pthreads on openbsd <4.4 (broken sigaltstack, will
		56	pthreads fare better?).
		57	- be less picky about destroying "a" running coroutine.
		58
		59	5.11 Tue Nov 25 21:49:05 CET 2008
		60	- DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
		61	working code with failed assertions, introducing more bugs than
		62	it fixes, requiring elaborate workarounds :(
		63
		64	5.1 Mon Nov 24 08:54:59 CET 2008
		65	- wrote a small introductory tutorial - Coro::Intro.
		66	- convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
		67	- Coro::Select did errornously dup the file descriptors
		68	and didn't work with all AnyEvent backends.
		69	- Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
		70	LWP data transfers.
		71	- disassociate c contexts from coro objects - this is agruably more
		72	correct, but mostly allows sharing of cctxs between coro and state
		73	objects, for added memory savings and speed increases.
		74	- bumped $Coro::POOL_RSS up to 32kb by default.
		75	- no longer set the optype to OP_CUSTOM, as B::* understandably
		76	doesn't like this very much (and we are a type of entersub).
		77	- implement state cloning, just to prove that call/cc can be done.
		78	- automatically load Coro::AnyEvent in Coro::Handle.
		79	- wrap ->cancel calls in eval inside Coro::Handle as EV watchers
		80	do not have this method (and don't need it either).
		81	- speed up generic anyevent methods in Coro::Handle by using rouse
		82	callbacks.
		83	- allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
		84	others. It also makes the debugger happier, as you can trace
		85	through the idle threads now.
		86	- add comppad_name* and hints ($^H, %^H) to per-thread variables.
		87	- eg/event was pretty broken.
		88	- better 5.8.6 compatibility.
		89
		90	5.0 Thu Nov 20 10:35:05 CET 2008
		91	- NEW ARCHITECTURE: use the latest 4.x version if you experience
		92	stability issues.
		93	- bump API version to 7 - all dependents must be recompiled.
		94	- removed timed_* functions - they were not being used anyways
		95	and should be replaced by a more generic mechanism -
		96	and were annoying to support anyways :)
		97	- removed SemaphoreSet's waiter method - use sem method instead.
		98	- Coro::Semaphore->adjust didn't correctly wake up enough waiters.
		99	- async_pool did free a scalar value twice
		100	("Attempt to unreference...").
		101	- fix a longstanding bug where calling terminate on a coro that
		102	was waiting for a semaphore that was just becoming available
		103	would cause a deadlock (semaphore would get into a state where
		104	it was available but waiters were still blocked).
		105	- calling throw on a coroutine that is waiting for a semaphore will
		106	no longer make it acquire the semaphore (and thus leak a count).
		107	- perl's process emulation is now not even theoretically supported
		108	anymore.
		109	- new functions Coro::rouse_cb and Coro::rouse_wait for easier
		110	conversion of callback-style to blocking-style.
		111	- new methods $coro->schedule_to and ->cede_to, to specifically
		112	schedule or cede to a specific coroutine.
		113	- new function Coro::Semaphore::wait.
		114	- use named constants in Coro::Channel (Richard Hundt).
		115	- directly patch the entersub opcode calling SLF functions (cede,
		116	transfer and so on). this does speed up context switching, but
		117	more importanly, it frees us from the hardcoded behaviour of
		118	entersub, so we might actually be able to return something from
		119	those functions and atcually create new ones.
		120	- take advantage of __builtin_frame_address on gcc.
		121	- expose THX in coroapi (not sure whether this was a wise decision,
		122	as "threaded" perls are running at half speed anyways).
		123	- implement execute_slf (schedule-like-function) interface that makes
		124	it possible to implement schedule-like-functions in XS.
		125	- use new SLF interface to massively speed up Coro::EV by roughly a
		126	factor of two.
		127	- used new SLF interface to massively speed up Coro::Semaphore by a
		128	factor of three.
		129	- used new SLF interface to speed up Coro::AIO by roughly a factor of
		130	four and reduce its memory usage considerably.
		131	- implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
		132	for a nice speedup and vastly more correct behaviour. Also implement
		133	a new method "sem" to get at the underlying semaphore object.
		134	- implement Coro::Channel in terms of Coro::Semaphore, for a moderate
		135	(in comparison) 20-40% speedup.
		136	- used new SLF interface to reimplement Coro::Signal gaining
		137	some unknown (because I was too lazy), but certain, speedup, and also
		138	making signals reliable for the first time.
		139	- used new SLF interface and other optimisations to speed up async_pool
		140	by a factor of two. It also doesn't rely on perl's exception mechanism
		141	to exit anymore. The overhead for terminating an async_pool, coro over
		142	a normal async is now very small.
		143	- sped up coroutine creation/destruction by 40%.
		144	- forgot to include Coro/libcoro/README in the dist for all these years.
		145	- work around a freebsd pthreads bug (manual testcancel is required as
		146	pthread_cond_wait isn't a cancellation point on freebsd).
		147	- use new rouse functions to speed up and simplify Coro::BDB.
		148	- make "prefer perl native functions" work with threaded perls.
		149	- condense Coro::Debug ps output, hint at v and w flags.
		150	- (libcoro) lots of minor cleanups and portability improvements.
		151
		152	4.914 Wed Nov 19 12:54:18 CET 2008
		153	- fix a disastrous bug in the readline optimisation
		154	introduced in 4.801.
		155
		156	4.913 Sat Nov 15 07:58:28 CET 2008
		157	- async_pool did free a scalar value twice
		158	("Attempt to unreference...").
		159
		160	4.912 Thu Nov 13 18:31:23 CET 2008
		161	- minor cleanups.
		162	- use much larger stacks on linux and perl < 5.8.8.
		163	- Coro::Debug::new_unix_server did not unlink the socket
		164	when destroyed.
		165
		166	4.911 Tue Nov 11 04:26:17 CET 2008
		167	- "port" to threaded perls.
		168
		169	4.91 Mon Nov 10 05:36:38 CET 2008
		170	- the ->throw exception object no longer leaks.
		171	- creating a new cctx leaked a scopestack entry (memleak).
		172	- new coroutines didn't get created with a zero flags field
		173	(unknown impact).
		174	- calling ->throw on a not-yet-started coroutine should now work
		175	instead of being ignored.
		176	- ->throw is now supported on Coro::State objects.
		177	- clean up cctx creation code a bit.
		178	- entersub is actually a UNOP, not a LOGOP (not a bugfix).
		179
		180	4.9 Sat Nov 8 17:45:27 CET 2008
