8 - blush, condvar values would not be propagated from send to recv anymore
9 (reported by Chip Salzenberg).
10 - use exponential increase for the readline buffer length in
11 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
12
136.04 Wed Aug 3 17:15:45 CEST 2011
14 - use even more efficient and more compatible condvars for
15 compatibility to AnyEvent 6.x :)
16 - more inconsequential ecb.h updates.
17
186.03 Wed Aug 3 11:41:30 CEST 2011
19 - change how Coro patches AnyEvent condvars for compatibility to
20 AnyEvent 6.x.
21 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
22 hasn't been included.
23
246.02 Wed Jul 13 04:35:19 CEST 2011
25 - "improve portability to Gentoo" - gentoo manages to put perl variables
26 in memory areas that are farther than 2gb apart, which the jit couldn't
27 handle and barfed. now it's just a bit slower on gentoo and similar
28 systems.

306.01 Sun Jul 3 12:31:14 CEST 2011
31 - workarounds are good, but the test for whether pthreads are used
32 was not good. thisone should be better.
33 - check differently whether gcc generates cfi instructions itself.

356.0 Wed Jun 29 19:43:35 CEST 2011
36 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
37 destroyed and cleaned up automatically (e.g. async { schedule }).
38 - implement a JIT compiler for part of the thread switch code,
39 which gives a 50% speed improvement on threaded perls, and
40 about 4% on non-thraeded perls (so threaded perls now finally
41 reach about half the speed of non-threaded perls).
42 - slightly modernise Coro::Intro, add section about rouse functions.
43 - avoid DEFSV and ERRSV, giving another 10% improvement
44 in thread switching.
45 - Coro::State->is_destroyed is now called is_zombie.
46 - implement a Coro->safe_cancel method that might fail, but
47 cancels in a "safer" way if it succeeds.
48 - add preliminary support for DEBUGGING perls.
49 - get rid of two hash-accesses when initialising a new Coro - this
50 speeds up coro creation by almost a factor of two.
51 - croak when a coro that is being cancelled tries to block
52 (e.g. while executing a guard block), instead of crashing or
53 deadlocking.
54 - use a more robust and also faster method to identify Coro::State
55 objects - speeds up everything a bit.
56 - implement Coro->cancel in XS for a 20% speed improvement, and to
57 be able to implement mutual cancellation.
58 - speed up context switches by a percent or two by more efficiently
59 allocating context stack entries.
60 - implement Coro->join and Coro->on_destroy in XS for a speedup and
61 a reduction in memory use.
62 - cancelling a coro while it itself is cancelling another coro is
63 now supported and working, instead of triggering an assertion.
64 - be a bit more crash-resistant when calling (buggy) on_destroy
65 callbacks (best effort).
66 - move on_destroy into the slf_frame, to allow extension slf
67 functions to have destructors.
68 - get rid if coro refcounting - simply crash in other interpreter
69 threads by nulling the pointers on clone.
70 - simplify warn/die hook handling when loading Coro - the convoluted
71 logic seems to be no longer neccessary.
72 - use libecb instead of our own home-grown gcc hacks.
73 - document alternatives to Coro::LWP. Please use them :)
74 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
75 sigaltstack. Really. wine suffers from it, erlang suffers from it,
76 and it's known since at least 2006.
77
785.372 Wed Feb 23 06:14:30 CET 2011
79 - apparently mingw doesn't provide a working gettimeofday, try to
80 work around that by relying on Time::HiRes (indirectly brought to
81 my attention by Max Maischein).
82 - fix some portability issues when Time::HiRes was used.
83
845.371 Mon Feb 21 14:36:08 CET 2011
85 - backport to windows process emulation code again.
86
875.37 Sat Feb 19 07:49:44 CET 2011
88 - add a big "Coro thread life cycle" section to "man Coro".
89 - try a tentative workaround against the breakage that 5.13 has
90 introduced without depreciation period. sigh.
91 - no longer use Time::HiRes if gettimeofday is available, which
92 saves quite a lot of memory.
93
945.36 Sun Feb 13 05:33:41 CET 2011
95 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
96 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
97 method call.
98 - undocument Coro::Timer::sleep and obsolete whole module.
99 - optimise Coro::Timer::timeout memory and cpu usage.
100 - slightly updated Coro::Intro for recent changes.
101 - do not initialise PL_dirty anymore.
102
1035.25 Thu Nov 11 01:08:39 CET 2010
104 - try a different approach on netbsd - netbsd 5 finally has marginally
105 working pthreads, but still broken ucontext/sigaltstack.
106 - openbsd 4.8 finally got their act together, Coro works out of the box
107 with asm, setjmp and pthreads (no change, just informational).
108
1095.24 Sat Oct 23 11:27:12 CEST 2010
110 - port to the EV 4.0 API.
111 - work around bugs in mingw32, making strawberry perl work
112 out of the box.
113 - correctly modify Coro::AIO function prototypes
114 so that they reflect the "no optional parameters" rule.
115 - "ported" libcoro to C++.
116
1175.23 Mon May 17 18:50:42 CEST 2010
118 - be more resistant to ordering changes when initialising
119 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
120 Waldorf).
121 - document that perl 5.12 deliberately removed support for cloning.
122
1235.22 Wed Apr 14 03:55:35 CEST 2010
124 - correctly return udnef on errors in Coro::Handle::read/write
125 (testcase by Marc Mims).
