10 - support magic values as timed_io_once args.
11 - recommend AnyEvent 7+ or EV 4+, also require EV
12 version 4 or newer for Coro::EV.

146.10 Tue Oct 9 01:14:27 CEST 2012
15 - updated ecb.h, it had a typo that caused it to not compile on many
16 big endian systems (reported by many people).
17 - disable memory fences in ecb.h to improve portability.
18
196.09 Sat Oct 6 23:25:02 CEST 2012
20 - Coro::EV I/O watchers were not interruptible by exceptions
21 (Coro::State::throw) (testcase by sten).
22 - ->throw now puts threads into the ready queue, as this seems to
23 be expected by existing code, and code that doesn't cope with spurious
24 wakeups needs fixing anyway.
25 - use fd -1 in mmap.
26 - cast I32 to int in error message printf.
27 - warn about broken so-called "hardened" kernels.
28
296.08 Fri Apr 13 12:05:47 CEST 2012
30 - be more aggressive about exiting like perl does - formerly,
31 exiting from the non-main thread would not execute END blocks.
32
336.07 Fri Nov 11 21:21:48 CET 2011
34 - work around a bug in PerlIO (setting $SIG{__WARN__} to a PVCV).
35 - update ecb.h.
36
376.06 Mon Aug 8 23:59:48 CEST 2011
38 - cygwin unfortunately patches the stack at runtime, so we use the pthreads
39 backend, which is an order of magnitude slower. unfortunately, cygwins
40 pthread implementation isn't very complete either, so allocate the stack
41 twice just to be sure.
42 (note: cygwin also enables mymalloc, which is NOT THREADSAFE ON WINDOWS,
43 in its ithreaded perl - best recompile cygwin and use the 'w'indows
44 backend for much better performance. also disable ithreads for
45 even better performance...).
46
476.05 Thu Aug 4 21:36:36 CEST 2011
48 - blush, condvar values would not be propagated from send to recv anymore
49 (reported by Chip Salzenberg).
50 - use exponential increase for the readline buffer length in
51 Coro::Handle. also reduce initial allocation to 1020 from 4096 bytes.
52
536.04 Wed Aug 3 17:15:45 CEST 2011
54 - use even more efficient and more compatible condvars for
55 compatibility to AnyEvent 6.x :)
56 - more inconsequential ecb.h updates.
57
586.03 Wed Aug 3 11:41:30 CEST 2011
59 - change how Coro patches AnyEvent condvars for compatibility to
60 AnyEvent 6.x.
61 - update ecb.h, to no longer include <pthread.h> in case WinNT.h
62 hasn't been included.
63
646.02 Wed Jul 13 04:35:19 CEST 2011
65 - "improve portability to Gentoo" - gentoo manages to put perl variables
66 in memory areas that are farther than 2gb apart, which the jit couldn't
67 handle and barfed. now it's just a bit slower on gentoo and similar
68 systems.
69
706.01 Sun Jul 3 12:31:14 CEST 2011
71 - workarounds are good, but the test for whether pthreads are used
72 was not good. thisone should be better.
73 - check differently whether gcc generates cfi instructions itself.

10 destroyed and cleaned up automatically (e.g. async { schedule }). 77 destroyed and cleaned up automatically (e.g. async { schedule }).
78 - implement a JIT compiler for part of the thread switch code,
79 which gives a 50% speed improvement on threaded perls, and
80 about 4% on non-thraeded perls (so threaded perls now finally
81 reach about half the speed of non-threaded perls).
82 - slightly modernise Coro::Intro, add section about rouse functions.
83 - avoid DEFSV and ERRSV, giving another 10% improvement
84 in thread switching.
11 - Coro::State->is_destroyed is now called is_zombie. 85 - Coro::State->is_destroyed is now called is_zombie.
12 - implement a Coro->safe_cancel method that might fail, but 86 - implement a Coro->safe_cancel method that might fail, but
13 cancels in a "safer" way if it succeeds. 87 cancels in a "safer" way if it succeeds.
88 - add preliminary support for DEBUGGING perls.
14 - get rid of two hash-accesses when initialising a new Coro - this 89 - get rid of two hash-accesses when initialising a new Coro - this
15 speeds up coro creation by almost a factor of two. 90 speeds up coro creation by almost a factor of two.

112 - use libecb instead of our own home-grown gcc hacks.
113 - document alternatives to Coro::LWP. Please use them :)
114 - work around another mindless idiotic NEEDLESS bug in openbsd/mirbsds
115 sigaltstack. Really. wine suffers from it, erlang suffers from it,
116 and it's known since at least 2006.

39 - apparently mingw doesn't provide a working gettimeofday, try to 119 - apparently mingw doesn't provide a working gettimeofday, try to
40 work around that by relying on Time::HiRes (indirectly brought to 120 work around that by relying on Time::HiRes (indirectly brought to
41 my attention by Max Maischein). 121 my attention by Max Maischein).
