12 - the autogenerated prototypes of Coro::AIO now add ";" at the end
13 to avoid generating named unary operators and messing up parsing
14 (mostly affects aio_mlockall 4 | 8 which was parsed as
15 (aio_mlockall 4) | 8).
16 - do not use a prototype for select in Coro::Select, as CORE::select also
17 doesn't have one.
18
196.52 Tue Aug 14 18:49:43 CEST 2018
20 - libcoro update: allow sharing of coro threads using the pthreads
21 backend among different pthreads, as is required by Coro::Multicore.
22 - always allow ->call and ->eval when the coro is the current coroutine. this
23 makes it possible, among other things, to call these on $Coro::main.
24 - minor code cleanups.
25
266.514 Thu Aug 31 18:25:31 CEST 2017
27 - safe_cancel no longer croaks when called on already-destroyed
28 thread, but instead "just works".
29
306.513 Sat Jul 15 01:18:51 CEST 2017
31 - experimental 5.22 comaptibility changes (PadlistNAMES).
32 - removed attributes example and made sure the other examples
33 still work.
34 - fix some statevar types for newer perls, should be of no consequence.
35
366.512 Fri Jul 14 05:03:17 CEST 2017
37 - seems to pass test suite down till 5.8.9, so make this the
38 minimum requirement in Makefile.PL.
39 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
40 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
41 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
42 fortified longjmp variants in some libcs.
43 - re-try JIT allocation without PROT_EXEC, to hopefully improve
44 portability (still doesn't seem to work around broken selinux
45 mmap everywhere).
46 - speling fixes (Xavier Guimard).
47
486.511 Sun Jun 26 23:44:50 CEST 2016
49 - make it compile with threaded perls again.
50 - simplify and speed up __DIE__ and __WARN__ handling.
51
526.51 Sat Jun 25 20:57:20 CEST 2016
53 - 6.5 release didn't compile on most older perls due to
54 a logic error enabling experimental 5.24 code for all versions.
55 - since various broken or deficient patches float around
56 to work around the vtbl API breakage in perl, let's provide
57 our own workaround, which seems to be much less invasive
58 and more compatible than the approaches seen so far. YMMV.
59 - work around assertion failure in perl_destruct on 5.24
60 (analyzed by Dave Mitchell).
61
626.5 Wed Jun 22 22:23:50 CEST 2016
63 - swap_sv swapping order was not symmetrical, causing
64 wrong swaps when swap_sv was used multiple times on the
65 same sv in the same thread.
66 - swap_sv calls can now be undone by calling it again
67 with the same variables.
68 - swap_sv calls will now be undone in async_pool threads.
69 - split Coro::Semaphore::up/adjust into separate xs functions
70 for better error reporting, at slight codesize increase.
71 - (libcoro) arm assembly support, please test and report.
72 - adjust to PL_savestack changes in perl 5.24 (adapted from
73 the debian patch, which unfortunately gets it wrong).
74
756.49 Sat Oct 17 01:40:12 CEST 2015
76 - throwing an exception to a thread waiting in
77 Coro::Handle using Coro::EV did not stop the watchers,
78 causing the next call to fail (testcase by Martin Pritchard).
79 - bump minimum perl version to 5.10.
80
816.48 Sun Oct 4 19:03:51 CEST 2015
82 - fix memory leak when Coro::Handle uses Coro::EV internally
83 (testcase by Sten Sten).
84 - update code to libev 4 API (internally, Coro still used the
85 version 3 API calls).
86 - remove unused hv_sig.
87
886.47 Sat Jul 11 03:58:20 CEST 2015
89 - swap_svs - NVs can be in the SV head beginning with 5.20.
90
916.46 Tue Jun 30 14:36:30 CEST 2015
92 - restore portability to perls with windows fork emulation
93 (patch by Petr Písař).
94
956.45 Tue Jun 30 01:40:08 CEST 2015
96 - restore portability to perl 5.16 and below.
97
986.44 Tue Jun 30 00:41:54 CEST 2015
99 - avoid segfaulting (or worse) when tracing a canceled thread.
100 - the Event module silently broke it's public hook API, causing
101 failures on perls compiled with -Duselongdouble. Requiring
102 the latest version of Event because I don't know which release
103 changed this (it's not mentioned in the ChangeLog).
104 - allow xs level enterleave hooks via CoroAPI.
105
1066.43 Thu Jun 4 15:38:14 CEST 2015
107 - use stability canary.
108 - port to stableperl-5.22.0-1.001.
109 - update libecb.
110
1116.42 Wed Feb 11 20:29:52 CET 2015
112 - Coro::SemaphoreSet->try did not actually work (analyzed by
113 SATO Kentaro).
114 - upgrade libecb to be C11 compliant.
115
1166.41 Sat Sep 6 22:08:46 CEST 2014
117 - restore portability to perl 5.8.x.
118 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
119 up some memory, but fixes "use feature" and similar modules
120 when used inside a Coro.
121 - allow zero as argument to Coro::Channel to mean the same thing
122 as no argument. this works with older versions as well,
123 but wasn't legal until now.
124 - slightly better c header file detection.
125
1266.39 Mon Jun 2 00:00:08 CEST 2014
127 - work around more incompatible changes in 5.20.
128
1296.38 Sun Jun 1 21:54:23 CEST 2014
130 - check that perl slots actually have enough space to hold
131 interpreter variables.
132 - untested port to perl 5.19 (64 bit tmps indices) (reported
133 by Andreas König).
134 - croak when cancel is called without a thread context.
135
1366.37 Tue Mar 4 13:27:33 CET 2014
137 - *sigh*, removed leftover debugging code from debugging a
138 perl bug, of all things.
139
1406.36 Tue Mar 4 07:11:59 CET 2014
141 - semaphores would not clear the destroy hook when interrupted
142 by ->throw, causing segfaults or worse.
143 - ->throw on a thread waiting for a semaphore did not acquire
144 the semaphore, but also didn't wake up other waiters,
145 possibly causing a deadlock.
146 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
147 to report a full stacktrace, which should help find out
148 where the actual call is.
149 - "atomically" destroy data in slf_destroy, because it is
150 the right thing to do, just in case.
151 - disable ecb.h libm dependency, to compile on ancient systems
152 or under adverse conditions.

10 - do not crash when freeing padlists with holes (in 5.18). 155 - do not crash when freeing padlists with holes (in 5.18).

121 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be 266 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
122 destroyed and cleaned up automatically (e.g. async { schedule }). 267 destroyed and cleaned up automatically (e.g. async { schedule }).
123 - implement a JIT compiler for part of the thread switch code, 268 - implement a JIT compiler for part of the thread switch code,
124 which gives a 50% speed improvement on threaded perls, and 269 which gives a 50% speed improvement on threaded perls, and
125 about 4% on non-thraeded perls (so threaded perls now finally 270 about 4% on non-threaded perls (so threaded perls now finally
126 reach about half the speed of non-threaded perls). 271 reach about half the speed of non-threaded perls).
127 - slightly modernise Coro::Intro, add section about rouse functions. 272 - slightly modernise Coro::Intro, add section about rouse functions.
