7 - "improve portability to Gentoo" - gentoo manages to put perl variables
8 in memory areas that are farther than 2gb apart, which the jit couldn't
9 handle and barfed. now it's just a bit slower on gentoo.

12 - workarounds are good, but the test for whether pthreads are used
13 was not good. thisone should be better.
14 - check differently whether gcc generates cfi instructions itself.

17 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
18 destroyed and cleaned up automatically (e.g. async { schedule }).
19 - implement a JIT compiler for part of the thread switch code,
20 which gives a 50% speed improvement on threaded perls, and
21 about 4% on non-thraeded perls (so threaded perls now finally
22 reach about half the speed of non-threaded perls).
23 - slightly modernise Coro::Intro, add section about rouse functions.
24 - avoid DEFSV and ERRSV, giving another 10% improvement
25 in thread switching.
26 - Coro::State->is_destroyed is now called is_zombie.
27 - implement a Coro->safe_cancel method that might fail, but
28 cancels in a "safer" way if it succeeds.
29 - add preliminary support for DEBUGGING perls.
30 - get rid of two hash-accesses when initialising a new Coro - this
31 speeds up coro creation by almost a factor of two.
32 - croak when a coro that is being cancelled tries to block
33 (e.g. while executing a guard block), instead of crashing or
34 deadlocking.
35 - use a more robust and also faster method to identify Coro::State
36 objects - speeds up everything a bit.
37 - implement Coro->cancel in XS for a 20% speed improvement, and to
38 be able to implement mutual cancellation.
39 - speed up context switches by a percent or two by more efficiently
40 allocating context stack entries.
41 - implement Coro->join and Coro->on_destroy in XS for a speedup and
42 a reduction in memory use.
43 - cancelling a coro while it itself is cancelling another coro is
44 now supported and working, instead of triggering an assertion.
45 - be a bit more crash-resistant when calling (buggy) on_destroy
46 callbacks (best effort).
47 - move on_destroy into the slf_frame, to allow extension slf
48 functions to have destructors.
49 - get rid if coro refcounting - simply crash in other interpreter
50 threads by nulling the pointers on clone.
51 - simplify warn/die hook handling when loading Coro - the convoluted
52 logic seems to be no longer neccessary.
53 - use libecb instead of our own home-grown gcc hacks.
54 - document alternatives to Coro::LWP. Please use them :)
55 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
56 sigaltstack. Really. wine suffers from it, erlang suffers from it,
57 and it's known since at least 2006.
58

60 - apparently mingw doesn't provide a working gettimeofday, try to
61 work around that by relying on Time::HiRes (indirectly brought to
62 my attention by Max Maischein).
63 - fix some portability issues when Time::HiRes was used.
64
655.371 Mon Feb 21 14:36:08 CET 2011
66 - backport to windows process emulation code again.
67
685.37 Sat Feb 19 07:49:44 CET 2011
69 - add a big "Coro thread life cycle" section to "man Coro".
70 - try a tentative workaround against the breakage that 5.13 has
71 introduced without depreciation period. sigh.
72 - no longer use Time::HiRes if gettimeofday is available, which
73 saves quite a lot of memory.
74
755.36 Sun Feb 13 05:33:41 CET 2011
76 - automatically load Coro::Channel, Coro::RWLock, Coro::Semaphore,
77 Coro::SemaphoreSet, Coro::Signal and Coro::Specific on first "new"
78 method call.
79 - undocument Coro::Timer::sleep and obsolete whole module.
80 - optimise Coro::Timer::timeout memory and cpu usage.
81 - slightly updated Coro::Intro for recent changes.
82 - do not initialise PL_dirty anymore.
83
845.25 Thu Nov 11 01:08:39 CET 2010
85 - try a different approach on netbsd - netbsd 5 finally has marginally
86 working pthreads, but still broken ucontext/sigaltstack.
87 - openbsd 4.8 finally got their act together, Coro works out of the box
88 with asm, setjmp and pthreads (no change, just informational).
89
905.24 Sat Oct 23 11:27:12 CEST 2010
91 - port to the EV 4.0 API.
92 - work around bugs in mingw32, making strawberry perl work
93 out of the box.
94 - correctly modify Coro::AIO function prototypes
95 so that they reflect the "no optional parameters" rule.
96 - "ported" libcoro to C++.
97
985.23 Mon May 17 18:50:42 CEST 2010
99 - be more resistant to ordering changes when initialising
100 Coro::AnyEvent, Coro::EV and Coro::Event (reported by Matthias
101 Waldorf).
102 - document that perl 5.12 deliberately removed support for cloning.
103
1045.22 Wed Apr 14 03:55:35 CEST 2010
105 - correctly return udnef on errors in Coro::Handle::read/write
106 (testcase by Marc Mims).
