33.0 3TODO: better (earlier) error messages on broken transfer's
4TODO: destroy gets only called on cancel: fix(?)
5TODO: should explore PerlIO::via::CoroCede and PerlIO::via::CoroAIO.

73.61
8 - Coro::Storable caused an endless loop when thawing invalid
9 pst's sometimes.
10 - use a Semaphore in Coro::Storable, as Storable doesn't
11 seem to be reentrant (although it is documented to
12 be threadsafe...).
13 - fix Coro::Signal to bring back the original unreliable
14 but stateful semantics.
15
163.6 Sat Apr 14 17:13:31 CEST 2007
17 - added some bugfixes to get eg/myhttpd working again.
18 - added Coro::Storable for often-cede'ing freeze/thaw.
19 - try to do a clean exit when a coroutine calls exit
20 (EXPERIMENTAL).
21 - got rid of indirect call through _coro_init.
22 - updated the partly antique examples in eg/ to
23 work again and be a bit less magic, too.
24 - fixed Coro::Signal semantics to work as documented again.
25
263.55 Sun Mar 25 01:20:47 CET 2007
27 - add SAVE_DEFFH to save the default filehandle and enable
28 it by default.
29 - finally move socket-operations from Coro::Socket to Coro::Handle
30 to be able to unblock foreign sockets.
31 - add Coro::State::save_also and guarded_save.
32 - add count accessor to Coro::Semaphore.
33 - add Coro::State::cctx_stacksize.
34 - just for the fun of it, do not rely on implicit context,
35 which can dramatically improve performance, but people
36 using windows-process-emulation perls do not care much about
37 performance.
38
393.51 Sun Mar 4 14:18:04 CET 2007
40 - fixed a problem when you weakened references to Coro::State's
41 (patch by Yuval Kogman).
42
433.501 Wed Feb 28 12:44:07 CET 2007
44 - rename some global symbols as macosx from hell redefines
45 them without asking.
46
473.5 Tue Feb 13 20:22:53 CET 2007
48 - do AnyEvent model detection earlier, avoiding problems
49 caused by first using AnyEvent and later Coro::Event.
50 - implement and document Coro::Event event objects.
51 - fix a potential problem in Coro::Event causing crashes.
52 - initialise PL_comppad when creating a new coroutine,
53 avoids crashes on early coro destruction.
54
553.41 Mon Jan 22 19:19:49 CET 2007
56 - readline on Coro::Handle did not support undefined $/,
57 nor did it deliver partial lines on EOF or error.
58 - implement malloc fallback for stack allocation because
59 stupid broken idiotic OSX has a stupid broken
60 idiotic fits-the-whole-os mmap "implementation" and
61 my dick feels longer if Coro is portable even to
62 obsolete platforms.
63
643.4 Fri Jan 19 21:52:54 CET 2007
65 - remove t/09_timer.t, as it isn't really testing much
66 but was rather flaky in practise.
67 - async_pool coro would keep arguments and callback alive until
68 it was reused.
69 - cancellation of a coroutine could cause spurious idle calls
70 in cede_notself.
71
723.3 Sat Jan 6 03:45:00 CET 2007
73 - implement $coro->on_destroy.
74 - Coro::Event blocking semantics have been changed,
75 documented and - hopefully - improved.
76 - fix nice adding, not subtracting, from priority.
77 - fix ->prio and api_is_ready (patch by Mark Hinds).
78 - fixed an assert ("... == prev__cctx->idle_te")
79 that could errronously trigger.
80 - fix various large and small memleaks.
81 - use a (hopefully) more stable cancel implementation
82 that immediately frees the coroutine data.
83 - cede/cede_notself return a status now.
84 - added Coro::guard function.
85 - added a global coroutine pool for jobs (on my machine,
86 I can create and execute 48k simple coros/s with async,
87 and 128k coros with async_pool).
88 - Coro::AIO now uses the coroutine priority as io priority.
89
903.2 Fri Dec 22 05:07:09 CET 2006
91 - improve portability to slightly older perls.
92 - use cleaner coroutine destruction.
93 - simplify configuration for users.
94 - optionally (unrecommended) prefer perl functions over
95 their coro replacements.
96
973.11 Tue Dec 5 13:11:24 CET 2006
98 - fixed some bogus assert's, but as perl.h disables assert even
99 without NDEBUG (thank you very much), not too many people should
100 notice (that did include myself). Andreas König noticed, though :)
101 - do not save/restore PL_sortcxix on >= 5.9.x, it doesn't seem to have
102 it. Also noticed by Andreas König :)
103 - save/restore tainted status.
104 - verified to pass the testsuite on my 5.9.5.
105
1063.1 Mon Dec 4 23:03:40 CET 2006
107 - INCOMPATIBLE CHANGE: $/ is now per-coroutine (but slow).
108 - incompatible change: transfer flags are now per-state.
109 - give a better error message on deadlock.
110 - document Coro::nready.
111 - enhanced testsuite.
112
1133.01 Sun Dec 3 23:47:42 CET 2006
114 - forgot to include Coro::Timer.
115
1163.0 Sun Dec 3 22:57:25 CET 2006
117 - the "FINALLY COMPLETELY STABLE" release (coming soon:
118 the "FAMOUS LAST WORDS" release).
4 - reimplement a new stack sharing algorithm. 119 - implement a new stack sharing algorithm, which uses a stack
120 pool (size currently hardcoded).
5 - make stack sharing mandatory (it no longer uses a heuristic). 121 - make stack sharing mandatory (it no longer uses a heuristic).
6 - eval/die no longer cause weird problems under heavy use. 122 - eval/die no longer cause weird problems under heavy use.
7 - Coro::Event could cause livelocks if it was used but 123 - Coro::Event could cause livelocks if it was used but
8 no Coro::Event watchers were used. 124 no Coro::Event watchers were used.
125 - Coro::Event now uses asynccheck as prepare does not
126 check for changed watchers.
127 - Coro::Event allows multiple waiting coros and will wake up one
128 per event.
9 - Coro::Event should be cleaner and more efficient now. 129 - Coro::Event should be cleaner and more efficient now.
130 - new utility function Coro::unblock_sub.
131 - document the sad fact that Event is no longer reentrant.
132 - putting a coroutine into the ready queue twice could under
133 some circumstances lead to stack corruption.
10 - minor incompatibility: subclassing Coro::State is supported 134 - minor incompatibility: subclassing Coro::State is supported
11 directly now without going through a _coro_state member. 135 directly now without going through a _coro_state member.
12 - state/coro switching is much faster now. 136 - state/coro switching is much faster now.
13 - very minor optimisations and code/documentation cleanup. 137 - very minor optimisations and code/documentation cleanup.
14 - avoid problems due to compiler inlining. 138 - avoid problems due to compiler inlining.
15 - removed timers from Coro::Timer -> use AnyEvent instead. 139 - removed timers from Coro::Timer -> use AnyEvent instead.
16 - replaced Coro::idle coroutine by (cleaner) idle handler. 140 - replaced Coro::idle coroutine by (cleaner) idle handler.
17 - updated to newest libcoro. 141 - updated to newest libcoro.
18 - implement enhanced support for valgrind. 142 - implement enhanced support for valgrind.
19 - implement is_ready and return value for ready. 143 - implement is_ready and return value for ready.
144 - removed Coro::Cont, it was a misnomer (it's generators),
145 and it was somewhat annoying to get it right. Will come back
146 if somebody asks for it :)
147 - many ->wait methods and Coro::Event could return
148 spuriously without the event having happened.

22 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket 151 - made Coro::Util, Coro::Select, Coro::Handle and Coro::Socket
23 use AnyEvent, moved them to Coro/. 152 use AnyEvent, moved them to Coro/.
24 - added Coro::LWP which contains all the uglyness required to 153 - added Coro::LWP which contains all the uglyness required to
