10 - swap_sv swapping order was not symmetrical, causing
11 wrong swaps when swap_sv was used multiple times on the
12 same sv in the same thread.
13 - swap_sv calls can now be undone by calling it again
14 with the same variables.
15 - swap_sv calls will now be undone in async_pool threads.
16 - split Coro::Semaphore::up/adjust into separate xs functions
17 for better error reporting, at slight codesize increase.
18 - (libcoro) arm assembly support, please test and report.
19 - adjust to PL_savestack changes in perl 5.24 (adapted from
20 the debian patch, which unfortunately gets it wrong).
21
226.49 Sat Oct 17 01:40:12 CEST 2015
23 - throwing an exception to a thread waiting in
24 Coro::Handle using Coro::EV did not stop the watchers,
25 causing the next call to fail (testcase by Martin Pritchard).
26 - bump minimum perl version to 5.10.
27
286.48 Sun Oct 4 19:03:51 CEST 2015
29 - fix memory leak when Coro::Handle uses Coro::EV internally
30 (testcase by Sten Sten).
31 - update code to libev 4 API (internally, Coro still used the
32 version 3 API calls).
33 - remove unused hv_sig.
34
356.47 Sat Jul 11 03:58:20 CEST 2015
36 - swap_svs - NVs can be in the SV head beginning with 5.20.
37
386.46 Tue Jun 30 14:36:30 CEST 2015
39 - restore portability to perls with windows fork emulation
40 (patch by Petr Písař).
41
426.45 Tue Jun 30 01:40:08 CEST 2015
43 - restore portability to perl 5.16 and below.
44
456.44 Tue Jun 30 00:41:54 CEST 2015
46 - avoid segfaulting (or worse) when tracing a canceled thread.
47 - the Event module silently broke it's public hook API, causing
48 failures on perls compiled with -Duselongdouble. Requiring
49 the latest version of Event because I don't know which release
50 changed this (it's not mentioned in the ChangeLog).
51 - allow xs level enterleave hooks via CoroAPI.
52
536.43 Thu Jun 4 15:38:14 CEST 2015
54 - use stability canary.
55 - port to stableperl-5.22.0-1.001.
56 - update libecb.
57
586.42 Wed Feb 11 20:29:52 CET 2015
59 - Coro::SemaphoreSet->try did not actually work (analyzed by
60 SATO Kentaro).
61 - upgrade libecb to be C11 compliant.
62
636.41 Sat Sep 6 22:08:46 CEST 2014
64 - restore portability to perl 5.8.x.
65 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
66 up some memory, but fixes "use feature" and similar modules
67 when used inside a Coro.
68 - allow zero as argument to Coro::Channel to mean the same thing
69 as no argument. this works with older versions as well,
70 but wasn't legal until now.
71 - slightly better c header file detection.
72
736.39 Mon Jun 2 00:00:08 CEST 2014
74 - work around more incompatible changes in 5.20.
75
766.38 Sun Jun 1 21:54:23 CEST 2014
77 - check that perl slots actually have enough space to hold
78 interpreter variables.
79 - untested port to perl 5.19 (64 bit tmps indices) (reported
80 by Andreas König).
81 - croak when cancel is called without a thread context.
82
836.37 Tue Mar 4 13:27:33 CET 2014
84 - *sigh*, removed leftover debugging code from debugging a
85 perl bug, of all things.
86
876.36 Tue Mar 4 07:11:59 CET 2014
88 - semaphores would not clear the destroy hook when interrupted
89 by ->throw, causing segfaults or worse.
90 - ->throw on a thread waiting for a semaphore did not acquire
91 the semaphore, but also didn't wake up other waiters,
92 possibly causing a deadlock.
93 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
94 to report a full stacktrace, which should help find out
95 where the actual call is.
96 - "atomically" destroy data in slf_destroy, because it is
97 the right thing to do, just in case.
98 - disable ecb.h libm dependency, to compile on ancient systems
99 or under adverse conditions.
100
1016.33 Mon Nov 18 11:26:27 CET 2013
102 - do not crash when freeing padlists with holes (in 5.18).
103 - tentative SVt_BIND 5.19 port/fix.

10 - use a new algorithm to derive padlists for perl 5.18. The old 106 - use a new algorithm to derive padlists for perl 5.18. The old
11 one could lead to 0-pointer accesses inside perl (reported 107 one could lead to 0-pointer accesses inside perl (reported
12 by Darin McBride). 108 by Darin McBride).
