9 - seems to pass test suite down till 5.8.9, so make this the
10 minimum requirement in Makefile.PL.
11 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
12 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
13 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
14 fortified longjmp variants in some libcs.
15 - re-try JIT allocation without PROT_EXEC, to hopefully improve
16 portability (still doesn't seem to work around broken selinux
17 mmap everywhere).
18 - speling fixes (Xavier Guimard).

21 - make it compile with threaded perls again.
22 - simplify and speed up __DIE__ and __WARN__ handling.
23
246.51 Sat Jun 25 20:57:20 CEST 2016
25 - 6.5 release didn't compile on most older perls due to
26 a logic error enabling experimental 5.24 code for all versions.
27 - since various broken or deficient patches float around
28 to work around the vtbl API breakage in perl, let's provide
29 our own workaround, which seems to be much less invasive
30 and more compatible than the approaches seen so far. YMMV.
31 - work around assertion failure in perl_destruct on 5.24
32 (analyzed by Dave Mitchell).
33
346.5 Wed Jun 22 22:23:50 CEST 2016
35 - swap_sv swapping order was not symmetrical, causing
36 wrong swaps when swap_sv was used multiple times on the
37 same sv in the same thread.
38 - swap_sv calls can now be undone by calling it again
39 with the same variables.
40 - swap_sv calls will now be undone in async_pool threads.
41 - split Coro::Semaphore::up/adjust into separate xs functions
42 for better error reporting, at slight codesize increase.
43 - (libcoro) arm assembly support, please test and report.
44 - adjust to PL_savestack changes in perl 5.24 (adapted from
45 the debian patch, which unfortunately gets it wrong).
46
476.49 Sat Oct 17 01:40:12 CEST 2015
48 - throwing an exception to a thread waiting in
49 Coro::Handle using Coro::EV did not stop the watchers,
50 causing the next call to fail (testcase by Martin Pritchard).
51 - bump minimum perl version to 5.10.
52
536.48 Sun Oct 4 19:03:51 CEST 2015
54 - fix memory leak when Coro::Handle uses Coro::EV internally
55 (testcase by Sten Sten).
56 - update code to libev 4 API (internally, Coro still used the
57 version 3 API calls).
58 - remove unused hv_sig.
59
606.47 Sat Jul 11 03:58:20 CEST 2015
61 - swap_svs - NVs can be in the SV head beginning with 5.20.
62
636.46 Tue Jun 30 14:36:30 CEST 2015
64 - restore portability to perls with windows fork emulation
65 (patch by Petr Písař).
66
676.45 Tue Jun 30 01:40:08 CEST 2015
68 - restore portability to perl 5.16 and below.
69
706.44 Tue Jun 30 00:41:54 CEST 2015
71 - avoid segfaulting (or worse) when tracing a canceled thread.
72 - the Event module silently broke it's public hook API, causing
73 failures on perls compiled with -Duselongdouble. Requiring
74 the latest version of Event because I don't know which release
75 changed this (it's not mentioned in the ChangeLog).
76 - allow xs level enterleave hooks via CoroAPI.
77
786.43 Thu Jun 4 15:38:14 CEST 2015
79 - use stability canary.
80 - port to stableperl-5.22.0-1.001.
81 - update libecb.
82
836.42 Wed Feb 11 20:29:52 CET 2015
84 - Coro::SemaphoreSet->try did not actually work (analyzed by
85 SATO Kentaro).
86 - upgrade libecb to be C11 compliant.
87
886.41 Sat Sep 6 22:08:46 CEST 2014
89 - restore portability to perl 5.8.x.
90 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
91 up some memory, but fixes "use feature" and similar modules
92 when used inside a Coro.
93 - allow zero as argument to Coro::Channel to mean the same thing
94 as no argument. this works with older versions as well,
95 but wasn't legal until now.
96 - slightly better c header file detection.
97
986.39 Mon Jun 2 00:00:08 CEST 2014
99 - work around more incompatible changes in 5.20.
100
1016.38 Sun Jun 1 21:54:23 CEST 2014
102 - check that perl slots actually have enough space to hold
103 interpreter variables.
104 - untested port to perl 5.19 (64 bit tmps indices) (reported
105 by Andreas König).
106 - croak when cancel is called without a thread context.
107
1086.37 Tue Mar 4 13:27:33 CET 2014
109 - *sigh*, removed leftover debugging code from debugging a
110 perl bug, of all things.
