12 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
13
146.53 Sun Dec 16 10:33:15 CET 2018
15 - the autogenerated prototypes of Coro::AIO now add ";" at the end
16 to avoid generating named unary operators and messing up parsing
17 (mostly affects aio_mlockall 4 | 8 which was parsed as
18 (aio_mlockall 4) | 8).
19 - do not use a prototype for select in Coro::Select, as CORE::select also
20 doesn't have one.
21
226.52 Tue Aug 14 18:49:43 CEST 2018
23 - libcoro update: allow sharing of coro threads using the pthreads
24 backend among different pthreads, as is required by Coro::Multicore.
25 - always allow ->call and ->eval when the coro is the current coroutine. this
26 makes it possible, among other things, to call these on $Coro::main.
27 - minor code cleanups.
28
296.514 Thu Aug 31 18:25:31 CEST 2017
30 - safe_cancel no longer croaks when called on already-destroyed
31 thread, but instead "just works".
32
336.513 Sat Jul 15 01:18:51 CEST 2017
34 - experimental 5.22 comaptibility changes (PadlistNAMES).
35 - removed attributes example and made sure the other examples
36 still work.
37 - fix some statevar types for newer perls, should be of no consequence.
38
396.512 Fri Jul 14 05:03:17 CEST 2017
40 - seems to pass test suite down till 5.8.9, so make this the
41 minimum requirement in Makefile.PL.
42 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
43 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
44 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
45 fortified longjmp variants in some libcs.
46 - re-try JIT allocation without PROT_EXEC, to hopefully improve
47 portability (still doesn't seem to work around broken selinux
48 mmap everywhere).
49 - speling fixes (Xavier Guimard).
50
516.511 Sun Jun 26 23:44:50 CEST 2016
52 - make it compile with threaded perls again.
53 - simplify and speed up __DIE__ and __WARN__ handling.
54
556.51 Sat Jun 25 20:57:20 CEST 2016
56 - 6.5 release didn't compile on most older perls due to
57 a logic error enabling experimental 5.24 code for all versions.
58 - since various broken or deficient patches float around
59 to work around the vtbl API breakage in perl, let's provide
60 our own workaround, which seems to be much less invasive
61 and more compatible than the approaches seen so far. YMMV.
62 - work around assertion failure in perl_destruct on 5.24
63 (analyzed by Dave Mitchell).
64
656.5 Wed Jun 22 22:23:50 CEST 2016
66 - swap_sv swapping order was not symmetrical, causing
67 wrong swaps when swap_sv was used multiple times on the
68 same sv in the same thread.
69 - swap_sv calls can now be undone by calling it again
70 with the same variables.
71 - swap_sv calls will now be undone in async_pool threads.
72 - split Coro::Semaphore::up/adjust into separate xs functions
73 for better error reporting, at slight codesize increase.
74 - (libcoro) arm assembly support, please test and report.
75 - adjust to PL_savestack changes in perl 5.24 (adapted from
76 the debian patch, which unfortunately gets it wrong).
77
786.49 Sat Oct 17 01:40:12 CEST 2015
79 - throwing an exception to a thread waiting in
80 Coro::Handle using Coro::EV did not stop the watchers,
81 causing the next call to fail (testcase by Martin Pritchard).
82 - bump minimum perl version to 5.10.
83
846.48 Sun Oct 4 19:03:51 CEST 2015
85 - fix memory leak when Coro::Handle uses Coro::EV internally
86 (testcase by Sten Sten).
87 - update code to libev 4 API (internally, Coro still used the
88 version 3 API calls).
89 - remove unused hv_sig.
90
916.47 Sat Jul 11 03:58:20 CEST 2015
92 - swap_svs - NVs can be in the SV head beginning with 5.20.
93
946.46 Tue Jun 30 14:36:30 CEST 2015
95 - restore portability to perls with windows fork emulation
96 (patch by Petr Písař).
97
986.45 Tue Jun 30 01:40:08 CEST 2015
99 - restore portability to perl 5.16 and below.
100
1016.44 Tue Jun 30 00:41:54 CEST 2015
102 - avoid segfaulting (or worse) when tracing a canceled thread.
103 - the Event module silently broke it's public hook API, causing
104 failures on perls compiled with -Duselongdouble. Requiring
105 the latest version of Event because I don't know which release
106 changed this (it's not mentioned in the ChangeLog).
107 - allow xs level enterleave hooks via CoroAPI.
108
1096.43 Thu Jun 4 15:38:14 CEST 2015
110 - use stability canary.
111 - port to stableperl-5.22.0-1.001.
112 - update libecb.
113
1146.42 Wed Feb 11 20:29:52 CET 2015
115 - Coro::SemaphoreSet->try did not actually work (analyzed by
116 SATO Kentaro).
117 - upgrade libecb to be C11 compliant.
118
1196.41 Sat Sep 6 22:08:46 CEST 2014
120 - restore portability to perl 5.8.x.
121 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
122 up some memory, but fixes "use feature" and similar modules
123 when used inside a Coro.
124 - allow zero as argument to Coro::Channel to mean the same thing
125 as no argument. this works with older versions as well,
126 but wasn't legal until now.
127 - slightly better c header file detection.
128
1296.39 Mon Jun 2 00:00:08 CEST 2014
130 - work around more incompatible changes in 5.20.
131
1326.38 Sun Jun 1 21:54:23 CEST 2014
133 - check that perl slots actually have enough space to hold
134 interpreter variables.
135 - untested port to perl 5.19 (64 bit tmps indices) (reported
136 by Andreas König).
137 - croak when cancel is called without a thread context.
138
1396.37 Tue Mar 4 13:27:33 CET 2014
140 - *sigh*, removed leftover debugging code from debugging a
141 perl bug, of all things.
142
1436.36 Tue Mar 4 07:11:59 CET 2014
144 - semaphores would not clear the destroy hook when interrupted
145 by ->throw, causing segfaults or worse.
146 - ->throw on a thread waiting for a semaphore did not acquire
147 the semaphore, but also didn't wake up other waiters,
148 possibly causing a deadlock.
10 - FATAL: $Coro::IDLE blocked itself will now use Carp::confess 149 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
11 to report a full stacktrace, which should help find out 150 to report a full stacktrace, which should help find out
12 where the actual call is. 151 where the actual call is.
152 - "atomically" destroy data in slf_destroy, because it is
153 the right thing to do, just in case.
154 - disable ecb.h libm dependency, to compile on ancient systems
155 or under adverse conditions.

146.33 Mon Nov 18 11:26:27 CET 2013 1576.33 Mon Nov 18 11:26:27 CET 2013
15 - do not crash when freeing padlists with holes (in 5.18). 158 - do not crash when freeing padlists with holes (in 5.18).
16 - tentative SVt_BIND 5.19 port/fix. 159 - tentative SVt_BIND 5.19 port/fix.

131 reach about half the speed of non-threaded perls). 274 reach about half the speed of non-threaded perls).
132 - slightly modernise Coro::Intro, add section about rouse functions. 275 - slightly modernise Coro::Intro, add section about rouse functions.
