10 - make it compile with threaded perls again.
11 - simplify and speed up __DIE__ and __WARN__ handling.
12
136.51 Sat Jun 25 20:57:20 CEST 2016
14 - 6.5 release didn't compile on most older perls due to
15 a logic error enabling experimental 5.24 code for all versions.
16 - since various broken or deficient patches float around
17 to work around the vtbl API breakage in perl, let's provide
18 our own workaround, which seems to be much less invasive
19 and more compatible than the approaches seen so far. YMMV.
20 - work around assertion failure in perl_destruct on 5.24
21 (analyzed by Dave Mitchell).
22
236.5 Wed Jun 22 22:23:50 CEST 2016
24 - swap_sv swapping order was not symmetrical, causing
25 wrong swaps when swap_sv was used multiple times on the
26 same sv in the same thread.
27 - swap_sv calls can now be undone by calling it again
28 with the same variables.
29 - swap_sv calls will now be undone in async_pool threads.
30 - split Coro::Semaphore::up/adjust into separate xs functions
31 for better error reporting, at slight codesize increase.
32 - (libcoro) arm assembly support, please test and report.
33 - adjust to PL_savestack changes in perl 5.24 (adapted from
34 the debian patch, which unfortunately gets it wrong).
35
366.49 Sat Oct 17 01:40:12 CEST 2015
37 - throwing an exception to a thread waiting in
38 Coro::Handle using Coro::EV did not stop the watchers,
39 causing the next call to fail (testcase by Martin Pritchard).
40 - bump minimum perl version to 5.10.
41
426.48 Sun Oct 4 19:03:51 CEST 2015
43 - fix memory leak when Coro::Handle uses Coro::EV internally
44 (testcase by Sten Sten).
45 - update code to libev 4 API (internally, Coro still used the
46 version 3 API calls).
47 - remove unused hv_sig.
48
496.47 Sat Jul 11 03:58:20 CEST 2015
50 - swap_svs - NVs can be in the SV head beginning with 5.20.
51
526.46 Tue Jun 30 14:36:30 CEST 2015
53 - restore portability to perls with windows fork emulation
54 (patch by Petr Písař).
55
566.45 Tue Jun 30 01:40:08 CEST 2015
57 - restore portability to perl 5.16 and below.
58
596.44 Tue Jun 30 00:41:54 CEST 2015
60 - avoid segfaulting (or worse) when tracing a canceled thread.
61 - the Event module silently broke it's public hook API, causing
62 failures on perls compiled with -Duselongdouble. Requiring
63 the latest version of Event because I don't know which release
64 changed this (it's not mentioned in the ChangeLog).
65 - allow xs level enterleave hooks via CoroAPI.
66
676.43 Thu Jun 4 15:38:14 CEST 2015
68 - use stability canary.
69 - port to stableperl-5.22.0-1.001.
70 - update libecb.
71
726.42 Wed Feb 11 20:29:52 CET 2015
73 - Coro::SemaphoreSet->try did not actually work (analyzed by
74 SATO Kentaro).
75 - upgrade libecb to be C11 compliant.
76
776.41 Sat Sep 6 22:08:46 CEST 2014
78 - restore portability to perl 5.8.x.
79 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
80 up some memory, but fixes "use feature" and similar modules
81 when used inside a Coro.
82 - allow zero as argument to Coro::Channel to mean the same thing
83 as no argument. this works with older versions as well,
84 but wasn't legal until now.
85 - slightly better c header file detection.
86
876.39 Mon Jun 2 00:00:08 CEST 2014
88 - work around more incompatible changes in 5.20.
89
906.38 Sun Jun 1 21:54:23 CEST 2014
91 - check that perl slots actually have enough space to hold
92 interpreter variables.
93 - untested port to perl 5.19 (64 bit tmps indices) (reported
94 by Andreas König).
95 - croak when cancel is called without a thread context.
96
976.37 Tue Mar 4 13:27:33 CET 2014
98 - *sigh*, removed leftover debugging code from debugging a
99 perl bug, of all things.
100
1016.36 Tue Mar 4 07:11:59 CET 2014
102 - semaphores would not clear the destroy hook when interrupted
103 by ->throw, causing segfaults or worse.
104 - ->throw on a thread waiting for a semaphore did not acquire
105 the semaphore, but also didn't wake up other waiters,
106 possibly causing a deadlock.
10 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess 107 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess

110 - "atomically" destroy data in slf_destroy, because it is
111 the right thing to do, just in case.
13 - disable ecb.h libm dependency, to compile on ancient systems 112 - disable ecb.h libm dependency, to compile on ancient systems
