8	4.1	8	- remove debugging code related to MgPV_nolen_const, also try to
		9	make it compile with perl 5.8.6 (yes, apple apparently loves
		10	outdated software). Reported by John S.
		11
		12	4.744 Tue Jul 8 22:06:35 CEST 2008
		13	- correctly provide default DIE/WARN handlers as documented.
		14	- also overwrite PL_vtbl_sigelem.svt_clear, even though current
		15	implementations inside perl work fine for us.
		16
		17	4.743 Mon Jun 16 00:21:57 CEST 2008
		18	- when using Coro::EV without running EV::loop it could
		19	result in busy-waiting for events, this has been fixed.
		20	- reduce codesize and improve performance by using EV_DEFAULT_UC.
		21
		22	4.742 Sat May 31 14:10:21 CEST 2008
		23	- implement a workaround for (some) perl <5.8.8 versions.
		24	- require EV 3.3+.
		25
		26	4.741 Fri May 30 23:33:09 CEST 2008
		27	- tell netbsd how utterly broken their imitation of an OS is
		28	and refuse to build by default if pthreads are in use.
		29	- switch to "s" method on all bsd's by default, as their ucontext
		30	stuff seems just too broken.
		31	- fix a bug in Coro::Select.
		32
		33	4.74 Thu May 29 20:05:31 CEST 2008
		34	- do not test Coro::LWP for lack of dependencies.
		35	- do not test Coro::Select for lack of working perls.
		36
		37	4.73 Thu May 29 2008
		38	- fix a bug in Coro::EV which would cause it to block despite
		39	there being runnable coroutines.
		40	- sprinkle "no warnings" freely over everything, also suppress
		41	warnings for some other modules.
		42	- fix typo in WSAEWOULDBLOCK.
		43
		44	4.72 Sun May 25 05:14:36 CEST 2008
		45	- tweak META.yaml a bit, unfortunately, there is no documented way
		46	to have optional dependencies with CPAN. doh :(
		47	- avoid running some tests on windows because they would fail due to
		48	perl bug (broken fork, broken pipes...).
		49	- work around perl on windows bugs where perl returns undocumented
		50	error codes for sysread, syswrite etc. by taking advantage
		51	of AnyEvent's workaround for that problem.
		52	- use AnyEvent::Util::fh_nonblocking in Coro::Handle to work around
		53	a common perl implementation bug on windows.
		54	- use unix domain sockets in testsuite to work around
		55	common perl implementation bugs on widows (they are emulated by
		56	tcp sockets on windows. ugh.)
		57
		58	4.71 Sat May 24 20:01:27 CEST 2008
		59	- fix a bug in Coro::AnyEvent ("Usage: Coro::AnyEvent::_schedule()").
		60	- take advantage of async name resolution of AnyEvent::Util.
		61	- work around brutal inet_aton override in Coro::LWP.
		62	- take advantage of the readyhook in Coro::EV, for smoother
		63	scheduling.
		64
		65	4.7 Sun May 11 00:32:19 CEST 2008
		66	- completely reworked the Coro manpage.
		67	- added Coro::AnyEvent, generic event loop integration.
		68	- implement cancel, ready and kill commands in Coro::Debug.
		69	- document find_coro in Coro::Debug.
		70	- incompatible change: rename has_stack to has_cctx.
		71	- Coro::AIO and Coro::BDB no longer force event model detection,
		72	use AnyEvent::AIO and AnyEvent::BDB.
		73
		74	4.6 Sat Apr 26 10:05:14 CEST 2008
		75	- INCOMPATIBLE CHANGE: sub/code attributes are no longer supported
		76	by the Coro module. It was a mistake to have it in the first place.
		77	- (experimental) support for activestate perl 5.10 (method "w").
		78	- (experimental) support for strawberry perl (method "a").
		79	- coro_sigelem_set did not return a value although it had to,
		80	actual impact unknown.
		81
		82	4.51 Mon Apr 14 13:28:27 CEST 2008
		83	- make it compile again on 5.8.
		84
		85	4.50 Thu Apr 10 09:43:17 CEST 2008
		86	- I did it twice! (see 4.49).
		87
		88	4.49 Sun Apr 6 21:23:31 CEST 2008
		89	- grr, instead of compiling the recent changes on 5.10 only they
		90	were compiled on 5.8 only.
		91
		92	4.48 Sun Apr 6 20:36:46 CEST 2008
		93	- allow coroutine switches during eval's under 5.10.x, as it seems
		94	the parser is a per-interpreter option now, so this is safe
		95	(this might fix the odd crashing bug).
		96	- drop support for 5.9.x versions: they are dead, jim.
		97
		98	4.47 Sun Apr 6 00:37:52 CEST 2008
		99	- force cctx allocation on API calls: we know we need to force one
		100	and gcc actually manages to confuse our heuristic nowadays,
		101	leading to crashes and worse.
		102	- document force_cctx.
		103
		104	4.46 Fri Apr 4 22:05:43 CEST 2008
		105	- upgrade libcoro, resulting in pthread-backend (which was only created
		106	to fulfill the rules of the programming languages shootout).
		107
		108	4.45 Thu Mar 13 11:55:36 CET 2008
		109	- fix a file leaking bug in eg/mhyttpd that would allow
		110	downloading of any file (reported by oesi).
		111	- fix deadlock bug in Coro::Channel (reported by Richard Hundt)
		112	(also add testcase).
		113	- support Broadcast option in Coro::Socket (patch by Richard Hundt,
		114	apparently having loads of fun with that).
		115	- implement $state->swap_defsv, ->swap_defav and document ->throw.
		116
		117	4.4 Wed Feb 13 16:44:29 CET 2008
		118	- only assume .cfi pseudo isns exist on GNU/Linux.
		119	- add get_timed method to Coro::Channels.
		120	- fixed Coro::Debug manpage.
		121	- perl 5.11 compatbility improvement based on patch by
		122	Andreas König.
		123
		124	4.37 Sun Jan 20 11:25:23 CET 2008
		125	- soften the check for an active parser for perl 5.10 (avoiding
		126	"Coro::State::transfer called while parsing" in many cases).
		127
		128	4.36 Sun Jan 13 10:53:56 CET 2008
		129	- reset diehook when terminating from an async_pool as to not
		130	trigger any __DIE__ handlers.
		131
		132	4.35 Sun Jan 13 04:14:13 CET 2008
		133	- "bt" debug command now displays any exceptions
		134	from longmess and also skips the innermost
		135	stackframes, giving more useufl output.
		136	- allow backtraces in coroutines blocked in Coro::EV,
		137	at a <1% speed hit.
		138	- handle localising of $SIG{__WARN__} and __DIE__
		139	properly (with a proper amount of dirty hacking).
		140
		141	4.34 Sat Dec 22 17:49:53 CET 2007
		142	- upgrade to EV version 2.0 API.
		143
		144	4.33 Mon Dec 17 08:36:12 CET 2007
		145	- make Coro::AIO etc. loadable in the absence of EV.
		146
		147	4.32 Mon Dec 17 07:46:02 CET 2007
		148	- majorly improved Coro::Handle's performance with Coro::EV.
		149	- implemented the until now mythical Coro::BDB module.
		150	- specialcase EV in Coro::AIO and Coro::BDB for extra speed.
		151
		152	4.31 Wed Dec 5 12:32:39 CET 2007
		153	- remove warn statement form Coro::Util.
		154
		155	4.3 Tue Dec 4 20:33:14 CET 2007
		156	- calls to the idle function could cause stack corruption
		157	when the stack changed.
		158	- do no longer rely on the presence of EV::DNS if EV is used
		159	(because it is gone), but instead take avdantage of EV::ADNS
		160	if available.
		161	- add ($) prototypes to all functions in Coro::Storable.
		162	- use a conventional (safer) idle callback in Coro::EV.
		163	- do accept quickly in Coro::Debug to avoid endless loops.
		164
		165	4.22 Fri Nov 30 16:04:04 CET 2007
		166	- really use optimised versions for Event and EV in Coro::Util
		167	and Coro::Handle.
		168
		169	4.21 Sun Nov 25 10:48:59 CET 2007
		170	- fix a spurious memory read.
		171	- Coro::EV no longer keeps the eventloop "alive".
		172
		173	4.2 Fri Nov 9 20:47:05 CET 2007
		174	- enable/disable tracing from a new coroutine, not a pooled one.
		175	- fix a memleak in Coro::Event.
		176	- removed killall call from fork_eval.
		177	- made sure store_fd is already loaded so that fork_eval
		178	does not have to parse autoload in each subprocess.
		179	- only use assembly method if -O switch is in $Config{optimize}.
		180	- add (optional) Coro::EV module, so far the best event loop module
		181	directly supported by Coro.
		182	- if the event model is EV, use EV::DNS to resolve
		183	stuff in Coro::Util.
		184	- don't get confused by multiple event notifications in Coro::Handle.
		185	- initial support for EV (libevent interface).
		186	- require Event and EV using configure_requires, to force their existance.
		187
		188	4.13 Wed Oct 24 07:26:45 CEST 2007
		189	- add Coro::Storable::blocking_thaw.
		190	- use a vastly more complicated technique to localise
		191	$SIG{__WARN/DIE__} that also works on perls <= 5.8.8.
		192	- use a coroutine for the idle callback Coro::Event,
		193	instead of running Event in the current coroutine context.
		194	This also catches recursive invocations.
		195	- actually report fork errors in gethostbyname and inet_aton.
		196
		197	4.11 Thu Oct 11 02:40:24 CEST 2007
		198	- port to threaded perls.
		199
		200	4.1 Thu Oct 11 02:38:16 CEST 2007
9	- incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now	201	- incompatible change: $SIG{__DIE__} and $SIG{__WARN__} will now
10	be local to each coro (see Coro::State).	202	be local to each coro (see Coro::State).
		203	- incompatible change: for very deep reasons, cede and cede_notself
		204	cannot return anything, so nothing will be returned.
11	- possibly bring back 5.10 compatibility (untested).	205	- possibly bring back 5.10 compatibility (untested).

		215	- stopping to trace a coroutine could destroy the cctx of
		216	an unrelated coroutine.
		217	- explain the relationship between Perl and C coroutines in
		218	more detail in Coro::State.
		219	- Coro::Util::inet_aton did not short-circuit dotted quad forms,
		220	causing a fork per resolve. This also affected Coro::Socket.
		221	- switch to a separate stack in $coro->call/eval to avoid
		222	invalidating pointers.
