9 - since various broken or deficient patches float around
10 to work around the vtbl API breakage in perl, let's provide
11 out own workaround, which seems to be much less invasive
12 and more compatible than the approaches seen so far. YMMV.
13 - work around assertion failure in perl_destruct on 5.24
14 (analyzed by Dave Mitchell).

166.5 Wed Jun 22 22:23:50 CEST 2016
17 - swap_sv swapping order was not symmetrical, causing
18 wrong swaps when swap_sv was used multiple times on the
19 same sv in the same thread.
20 - swap_sv calls can now be undone by calling it again
21 with the same variables.
22 - swap_sv calls will now be undone in async_pool threads.
23 - split Coro::Semaphore::up/adjust into separate xs functions
24 for better error reporting, at slight codesize increase.
25 - (libcoro) arm assembly support, please test and report.
26 - adjust to PL_savestack changes in perl 5.24 (adapted from
27 the debian patch, which unfortunately gets it wrong).
28
296.49 Sat Oct 17 01:40:12 CEST 2015
30 - throwing an exception to a thread waiting in
31 Coro::Handle using Coro::EV did not stop the watchers,
32 causing the next call to fail (testcase by Martin Pritchard).
33 - bump minimum perl version to 5.10.
34
356.48 Sun Oct 4 19:03:51 CEST 2015
36 - fix memory leak when Coro::Handle uses Coro::EV internally
37 (testcase by Sten Sten).
38 - update code to libev 4 API (internally, Coro still used the
39 version 3 API calls).
40 - remove unused hv_sig.
41
426.47 Sat Jul 11 03:58:20 CEST 2015
43 - swap_svs - NVs can be in the SV head beginning with 5.20.
44
456.46 Tue Jun 30 14:36:30 CEST 2015
46 - restore portability to perls with windows fork emulation
47 (patch by Petr Písař).
48
496.45 Tue Jun 30 01:40:08 CEST 2015
50 - restore portability to perl 5.16 and below.
51
526.44 Tue Jun 30 00:41:54 CEST 2015
53 - avoid segfaulting (or worse) when tracing a canceled thread.
54 - the Event module silently broke it's public hook API, causing
55 failures on perls compiled with -Duselongdouble. Requiring
56 the latest version of Event because I don't know which release
57 changed this (it's not mentioned in the ChangeLog).
58 - allow xs level enterleave hooks via CoroAPI.
59
606.43 Thu Jun 4 15:38:14 CEST 2015
61 - use stability canary.
62 - port to stableperl-5.22.0-1.001.
63 - update libecb.
64
656.42 Wed Feb 11 20:29:52 CET 2015
66 - Coro::SemaphoreSet->try did not actually work (analyzed by
67 SATO Kentaro).
68 - upgrade libecb to be C11 compliant.
69
706.41 Sat Sep 6 22:08:46 CEST 2014
71 - restore portability to perl 5.8.x.
72 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
73 up some memory, but fixes "use feature" and similar modules
74 when used inside a Coro.
75 - allow zero as argument to Coro::Channel to mean the same thing
76 as no argument. this works with older versions as well,
77 but wasn't legal until now.
78 - slightly better c header file detection.
79
806.39 Mon Jun 2 00:00:08 CEST 2014
81 - work around more incompatible changes in 5.20.
82
836.38 Sun Jun 1 21:54:23 CEST 2014
84 - check that perl slots actually have enough space to hold
85 interpreter variables.
86 - untested port to perl 5.19 (64 bit tmps indices) (reported
87 by Andreas König).
88 - croak when cancel is called without a thread context.
89
906.37 Tue Mar 4 13:27:33 CET 2014
91 - *sigh*, removed leftover debugging code from debugging a
92 perl bug, of all things.
93
946.36 Tue Mar 4 07:11:59 CET 2014
95 - semaphores would not clear the destroy hook when interrupted
96 by ->throw, causing segfaults or worse.
97 - ->throw on a thread waiting for a semaphore did not acquire
98 the semaphore, but also didn't wake up other waiters,
99 possibly causing a deadlock.
100 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
101 to report a full stacktrace, which should help find out
102 where the actual call is.
103 - "atomically" destroy data in slf_destroy, because it is
104 the right thing to do, just in case.
105 - disable ecb.h libm dependency, to compile on ancient systems
106 or under adverse conditions.
107
1086.33 Mon Nov 18 11:26:27 CET 2013
109 - do not crash when freeing padlists with holes (in 5.18).
9 - tentative SVt_BIND 5.19 port/fix. 110 - tentative SVt_BIND 5.19 port/fix.
