126.08 Fri Apr 13 12:05:47 CEST 2012
13 - be more aggressive about exiting like perl does - formerly,
14 exiting from the non-main thread would not execute END blocks.

166.07 Fri Nov 11 21:21:48 CET 2011
17 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
18 - update ecb.h.

21 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
22 backend, which is an order of magnitude slower. unfortunately, cygwins
23 pthread implementation isn't very complete either, so allocate the stack
24 twice just to be sure.
25 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
26 in its ithreaded perl - best recompile cygwin and use the 'w'indows
27 backend for much better performance. also disable ithreads for
28 even better performance...).

31 - blush, condvar values would not be propagated from send to recv anymore
32 (reported by Chip Salzenberg).
33 - use exponential increase for the readline buffer length in
34 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
35
366.04 Wed Aug 3 17:15:45 CEST 2011
37 - use even more efficient and more compatible condvars for
38 compatibility to AnyEvent 6.x :)
39 - more inconsequential ecb.h updates.
40
416.03 Wed Aug 3 11:41:30 CEST 2011
42 - change how Coro patches AnyEvent condvars for compatibility to
43 AnyEvent 6.x.
44 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
45 hasn't been included.
46

48 - "improve portability to Gentoo" - gentoo manages to put perl variables
49 in memory areas that are farther than 2gb apart, which the jit couldn't
50 handle and barfed. now it's just a bit slower on gentoo and similar
51 systems.
52
536.01 Sun Jul 3 12:31:14 CEST 2011
54 - workarounds are good, but the test for whether pthreads are used
55 was not good. thisone should be better.
56 - check differently whether gcc generates cfi instructions itself.

9 destroyed and cleaned up automatically (e.g. async { schedule }). 60 destroyed and cleaned up automatically (e.g. async { schedule }).
61 - implement a JIT compiler for part of the thread switch code,
62 which gives a 50% speed improvement on threaded perls, and
63 about 4% on non-thraeded perls (so threaded perls now finally
64 reach about half the speed of non-threaded perls).
65 - slightly modernise Coro::Intro, add section about rouse functions.
66 - avoid DEFSV and ERRSV, giving another 10% improvement
67 in thread switching.
10 - Coro::State->is_destroyed is now called is_zombie. 68 - Coro::State->is_destroyed is now called is_zombie.
11 - implement a Coro->safe_cancel method that might fail, but 69 - implement a Coro->safe_cancel method that might fail, but
12 cancels in a "safer" way if it succeeds. 70 cancels in a "safer" way if it succeeds.
71 - add preliminary support for DEBUGGING perls.

95 - use libecb instead of our own home-grown gcc hacks.
96 - document alternatives to Coro::LWP. Please use them :)
97 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
98 sigaltstack. Really. wine suffers from it, erlang suffers from it,

38 - apparently mingw doesn't provide a working gettimeofday, try to 102 - apparently mingw doesn't provide a working gettimeofday, try to
39 work around that by relying on Time::HiRes (indirectly brought to 103 work around that by relying on Time::HiRes (indirectly brought to
