106.47 Sat Oct 17 01:40:12 CEST 2015
11 - throwing an exception to a thread waiting in
12 Coro::Handle using Coro::EV did not stop the watchers,
13 causing the next call to fail (testcase by Martin Pritchard).
14 - bump minimum perl version to 5.10.
15
166.48 Sun Oct 4 19:03:51 CEST 2015
17 - fix memory leak when Coro::Handle uses Coro::EV internally
18 (testcase by Sten Sten).
19 - update code to libev 4 API (internally, Coro still used the
20 version 3 API calls).
21 - remove unused hv_sig.
22
236.47 Sat Jul 11 03:58:20 CEST 2015
24 - swap_svs - NVs can be in the SV head beginning with 5.20.
25
266.46 Tue Jun 30 14:36:30 CEST 2015
27 - restore portability to perls with windows fork emulation
28 (patch by Petr Písař).
29
306.45 Tue Jun 30 01:40:08 CEST 2015
31 - restore portability to perl 5.16 and below.
32
336.44 Tue Jun 30 00:41:54 CEST 2015
34 - avoid segfaulting (or worse) when tracing a canceled thread.
35 - the Event module silently broke it's public hook API, causing
36 failures on perls compiled with -Duselongdouble. Requiring
37 the latest version of Event because I don't know which release
38 changed this (it's not mentioned in the ChangeLog).
39 - allow xs level enterleave hooks via CoroAPI.
40
416.43 Thu Jun 4 15:38:14 CEST 2015
42 - use stability canary.
43 - port to stableperl-5.22.0-1.001.
44 - update libecb.
45
466.42 Wed Feb 11 20:29:52 CET 2015
47 - Coro::SemaphoreSet->try did not actually work (analyzed by
48 SATO Kentaro).
49 - upgrade libecb to be C11 compliant.
50
516.41 Sat Sep 6 22:08:46 CEST 2014
52 - restore portability to perl 5.8.x.
53 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
54 up some memory, but fixes "use feature" and similar modules
55 when used inside a Coro.
56 - allow zero as argument to Coro::Channel to mean the same thing
57 as no argument. this works with older versions as well,
58 but wasn't legal until now.
59 - slightly better c header file detection.
60
616.39 Mon Jun 2 00:00:08 CEST 2014
62 - work around more incompatible changes in 5.20.
63
646.38 Sun Jun 1 21:54:23 CEST 2014
65 - check that perl slots actually have enough space to hold
66 interpreter variables.
67 - untested port to perl 5.19 (64 bit tmps indices) (reported
68 by Andreas König).
69 - croak when cancel is called without a thread context.
70
716.37 Tue Mar 4 13:27:33 CET 2014
72 - *sigh*, removed leftover debugging code from debugging a
73 perl bug, of all things.
74
756.36 Tue Mar 4 07:11:59 CET 2014
76 - semaphores would not clear the destroy hook when interrupted
77 by ->throw, causing segfaults or worse.
78 - ->throw on a thread waiting for a semaphore did not acquire
79 the semaphore, but also didn't wake up other waiters,
80 possibly causing a deadlock.
81 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
82 to report a full stacktrace, which should help find out
83 where the actual call is.
84 - "atomically" destroy data in slf_destroy, because it is
85 the right thing to do, just in case.
86 - disable ecb.h libm dependency, to compile on ancient systems
87 or under adverse conditions.
88
896.33 Mon Nov 18 11:26:27 CET 2013
90 - do not crash when freeing padlists with holes (in 5.18).
91 - tentative SVt_BIND 5.19 port/fix.
92
936.32 Tue Nov 5 15:35:35 CET 2013
94 - use a new algorithm to derive padlists for perl 5.18. The old
95 one could lead to 0-pointer accesses inside perl (reported
96 by Darin McBride).
97
986.31 Thu May 9 07:39:48 CEST 2013
99 - Coro::AIO requests would crash if the thread was ready'd
100 while the request was ongoing.
101
1026.29 Wed May 8 02:55:18 CEST 2013
103 - when an on_destroy handler destructs the coro currently being
104 destructed a perl scalar could be accessed after being freed,
105 likely causing a crash.
106
1076.28 Wed Mar 6 06:58:02 CET 2013
108 - clean remnants of existing __DIE__ and __WARN__ handlers so
109 they lose their magic and will not cause segfaults later
110 (testcase by Andrey Sagulin).
7 - improved Coro::State documentation a bit. 111 - improved Coro::State documentation a bit.

117 - valgrind stack registering was broken.
