9 - experimental 5.24 compatibility changes.
10 - re-try JIT allocation without PROT_EXEC, to hopefully improve
11 portability.
12
136.511 Sun Jun 26 23:44:50 CEST 2016
14 - make it compile with threaded perls again.
15 - simplify and speed up __DIE__ and __WARN__ handling.
16
176.51 Sat Jun 25 20:57:20 CEST 2016
18 - 6.5 release didn't compile on most older perls due to
19 a logic error enabling experimental 5.24 code for all versions.
20 - since various broken or deficient patches float around
21 to work around the vtbl API breakage in perl, let's provide
22 our own workaround, which seems to be much less invasive
23 and more compatible than the approaches seen so far. YMMV.
24 - work around assertion failure in perl_destruct on 5.24
25 (analyzed by Dave Mitchell).
26
276.5 Wed Jun 22 22:23:50 CEST 2016
28 - swap_sv swapping order was not symmetrical, causing
29 wrong swaps when swap_sv was used multiple times on the
30 same sv in the same thread.
31 - swap_sv calls can now be undone by calling it again
32 with the same variables.
33 - swap_sv calls will now be undone in async_pool threads.
34 - split Coro::Semaphore::up/adjust into separate xs functions
35 for better error reporting, at slight codesize increase.
36 - (libcoro) arm assembly support, please test and report.
37 - adjust to PL_savestack changes in perl 5.24 (adapted from
38 the debian patch, which unfortunately gets it wrong).
39
406.49 Sat Oct 17 01:40:12 CEST 2015
41 - throwing an exception to a thread waiting in
42 Coro::Handle using Coro::EV did not stop the watchers,
43 causing the next call to fail (testcase by Martin Pritchard).
44 - bump minimum perl version to 5.10.
45
466.48 Sun Oct 4 19:03:51 CEST 2015
47 - fix memory leak when Coro::Handle uses Coro::EV internally
48 (testcase by Sten Sten).
49 - update code to libev 4 API (internally, Coro still used the
50 version 3 API calls).
51 - remove unused hv_sig.
52
536.47 Sat Jul 11 03:58:20 CEST 2015
54 - swap_svs - NVs can be in the SV head beginning with 5.20.
55
566.46 Tue Jun 30 14:36:30 CEST 2015
57 - restore portability to perls with windows fork emulation
58 (patch by Petr Písař).
59
606.45 Tue Jun 30 01:40:08 CEST 2015
61 - restore portability to perl 5.16 and below.
62
636.44 Tue Jun 30 00:41:54 CEST 2015
64 - avoid segfaulting (or worse) when tracing a canceled thread.
65 - the Event module silently broke it's public hook API, causing
66 failures on perls compiled with -Duselongdouble. Requiring
67 the latest version of Event because I don't know which release
68 changed this (it's not mentioned in the ChangeLog).
69 - allow xs level enterleave hooks via CoroAPI.
70
716.43 Thu Jun 4 15:38:14 CEST 2015
72 - use stability canary.
73 - port to stableperl-5.22.0-1.001.
74 - update libecb.
75
766.42 Wed Feb 11 20:29:52 CET 2015
77 - Coro::SemaphoreSet->try did not actually work (analyzed by
78 SATO Kentaro).
79 - upgrade libecb to be C11 compliant.
80
816.41 Sat Sep 6 22:08:46 CEST 2014
82 - restore portability to perl 5.8.x.
83 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
84 up some memory, but fixes "use feature" and similar modules
85 when used inside a Coro.
86 - allow zero as argument to Coro::Channel to mean the same thing
87 as no argument. this works with older versions as well,
88 but wasn't legal until now.
89 - slightly better c header file detection.
90
916.39 Mon Jun 2 00:00:08 CEST 2014
92 - work around more incompatible changes in 5.20.
93
946.38 Sun Jun 1 21:54:23 CEST 2014
95 - check that perl slots actually have enough space to hold
96 interpreter variables.
97 - untested port to perl 5.19 (64 bit tmps indices) (reported
98 by Andreas König).
99 - croak when cancel is called without a thread context.
100
1016.37 Tue Mar 4 13:27:33 CET 2014
102 - *sigh*, removed leftover debugging code from debugging a
103 perl bug, of all things.
104
1056.36 Tue Mar 4 07:11:59 CET 2014
106 - semaphores would not clear the destroy hook when interrupted
107 by ->throw, causing segfaults or worse.
108 - ->throw on a thread waiting for a semaphore did not acquire
109 the semaphore, but also didn't wake up other waiters,
110 possibly causing a deadlock.
111 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
112 to report a full stacktrace, which should help find out
113 where the actual call is.
114 - "atomically" destroy data in slf_destroy, because it is
115 the right thing to do, just in case.
116 - disable ecb.h libm dependency, to compile on ancient systems
117 or under adverse conditions.
118
1196.33 Mon Nov 18 11:26:27 CET 2013
120 - do not crash when freeing padlists with holes (in 5.18).
121 - tentative SVt_BIND 5.19 port/fix.

10 - use a new algorithm to derive padlists for perl 5.18. The old 124 - use a new algorithm to derive padlists for perl 5.18. The old
11 one could lead to 0-pointer accesses inside perl (reported 125 one could lead to 0-pointer accesses inside perl (reported
12 by Darin McBride). 126 by Darin McBride).
