12 - Coro::RWLock woke up only one reader instead of all after a wrlock
13 (analyzed and patch by Maxim Skorobogatov).
14 - slightly improved documentation of Coro::RWLock and RWLock testcase.
15 - quickly (re)-ported to minix 3.3 before minix crashed again.
16
176.54 Sun Dec 16 11:06:07 CET 2018
18 - reinstate Coro::Select::select prototype - it breaks more than it fixes.
19
206.53 Sun Dec 16 10:33:15 CET 2018
21 - the autogenerated prototypes of Coro::AIO now add ";" at the end
22 to avoid generating named unary operators and messing up parsing
23 (mostly affects aio_mlockall 4 | 8 which was parsed as
24 (aio_mlockall 4) | 8).
25 - do not use a prototype for select in Coro::Select, as CORE::select also
26 doesn't have one.
27
286.52 Tue Aug 14 18:49:43 CEST 2018
29 - libcoro update: allow sharing of coro threads using the pthreads
30 backend among different pthreads, as is required by Coro::Multicore.
31 - always allow ->call and ->eval when the coro is the current coroutine. this
32 makes it possible, among other things, to call these on $Coro::main.
33 - minor code cleanups.
34
356.514 Thu Aug 31 18:25:31 CEST 2017
36 - safe_cancel no longer croaks when called on already-destroyed
37 thread, but instead "just works".
38
396.513 Sat Jul 15 01:18:51 CEST 2017
40 - experimental 5.22 comaptibility changes (PadlistNAMES).
41 - removed attributes example and made sure the other examples
42 still work.
43 - fix some statevar types for newer perls, should be of no consequence.
44
456.512 Fri Jul 14 05:03:17 CEST 2017
46 - seems to pass test suite down till 5.8.9, so make this the
47 minimum requirement in Makefile.PL.
48 - experimental 5.24 compatibility changes (SUB_ARGARRAY).
49 - experimental 5.26 compatibility changes (PL_comppad -> PADOFFSET).
50 - disable FORTIFY_SOURCE to avoid broken (but well-intentioned)
51 fortified longjmp variants in some libcs.
52 - re-try JIT allocation without PROT_EXEC, to hopefully improve
53 portability (still doesn't seem to work around broken selinux
54 mmap everywhere).
55 - speling fixes (Xavier Guimard).
56
576.511 Sun Jun 26 23:44:50 CEST 2016
58 - make it compile with threaded perls again.
59 - simplify and speed up __DIE__ and __WARN__ handling.
60
616.51 Sat Jun 25 20:57:20 CEST 2016
62 - 6.5 release didn't compile on most older perls due to
63 a logic error enabling experimental 5.24 code for all versions.
64 - since various broken or deficient patches float around
65 to work around the vtbl API breakage in perl, let's provide
66 our own workaround, which seems to be much less invasive
67 and more compatible than the approaches seen so far. YMMV.
68 - work around assertion failure in perl_destruct on 5.24
69 (analyzed by Dave Mitchell).
70
716.5 Wed Jun 22 22:23:50 CEST 2016
72 - swap_sv swapping order was not symmetrical, causing
73 wrong swaps when swap_sv was used multiple times on the
74 same sv in the same thread.
75 - swap_sv calls can now be undone by calling it again
76 with the same variables.
77 - swap_sv calls will now be undone in async_pool threads.
78 - split Coro::Semaphore::up/adjust into separate xs functions
79 for better error reporting, at slight codesize increase.
80 - (libcoro) arm assembly support, please test and report.
81 - adjust to PL_savestack changes in perl 5.24 (adapted from
82 the debian patch, which unfortunately gets it wrong).
83
846.49 Sat Oct 17 01:40:12 CEST 2015
85 - throwing an exception to a thread waiting in
86 Coro::Handle using Coro::EV did not stop the watchers,
87 causing the next call to fail (testcase by Martin Pritchard).
88 - bump minimum perl version to 5.10.
89
906.48 Sun Oct 4 19:03:51 CEST 2015
91 - fix memory leak when Coro::Handle uses Coro::EV internally
92 (testcase by Sten Sten).
93 - update code to libev 4 API (internally, Coro still used the
94 version 3 API calls).
95 - remove unused hv_sig.
96
976.47 Sat Jul 11 03:58:20 CEST 2015
98 - swap_svs - NVs can be in the SV head beginning with 5.20.
99
1006.46 Tue Jun 30 14:36:30 CEST 2015
101 - restore portability to perls with windows fork emulation
102 (patch by Petr Písař).
103
1046.45 Tue Jun 30 01:40:08 CEST 2015
105 - restore portability to perl 5.16 and below.
106
1076.44 Tue Jun 30 00:41:54 CEST 2015
108 - avoid segfaulting (or worse) when tracing a canceled thread.
109 - the Event module silently broke it's public hook API, causing
110 failures on perls compiled with -Duselongdouble. Requiring
111 the latest version of Event because I don't know which release
112 changed this (it's not mentioned in the ChangeLog).
113 - allow xs level enterleave hooks via CoroAPI.
114
1156.43 Thu Jun 4 15:38:14 CEST 2015
116 - use stability canary.
117 - port to stableperl-5.22.0-1.001.
118 - update libecb.
119
1206.42 Wed Feb 11 20:29:52 CET 2015
121 - Coro::SemaphoreSet->try did not actually work (analyzed by
122 SATO Kentaro).
123 - upgrade libecb to be C11 compliant.
124
1256.41 Sat Sep 6 22:08:46 CEST 2014
126 - restore portability to perl 5.8.x.
127 - give new Coro's a valid GvHV(PL_hintgv) - this is slow and takes
128 up some memory, but fixes "use feature" and similar modules
129 when used inside a Coro.
130 - allow zero as argument to Coro::Channel to mean the same thing
131 as no argument. this works with older versions as well,
132 but wasn't legal until now.
133 - slightly better c header file detection.
134
1356.39 Mon Jun 2 00:00:08 CEST 2014
136 - work around more incompatible changes in 5.20.
137
1386.38 Sun Jun 1 21:54:23 CEST 2014
139 - check that perl slots actually have enough space to hold
140 interpreter variables.
141 - untested port to perl 5.19 (64 bit tmps indices) (reported
142 by Andreas König).
143 - croak when cancel is called without a thread context.
144
1456.37 Tue Mar 4 13:27:33 CET 2014
146 - *sigh*, removed leftover debugging code from debugging a
147 perl bug, of all things.
148
1496.36 Tue Mar 4 07:11:59 CET 2014
150 - semaphores would not clear the destroy hook when interrupted
151 by ->throw, causing segfaults or worse.
152 - ->throw on a thread waiting for a semaphore did not acquire
153 the semaphore, but also didn't wake up other waiters,
154 possibly causing a deadlock.
155 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
156 to report a full stacktrace, which should help find out
157 where the actual call is.
158 - "atomically" destroy data in slf_destroy, because it is
159 the right thing to do, just in case.
160 - disable ecb.h libm dependency, to compile on ancient systems
161 or under adverse conditions.

96.33 Mon Nov 18 11:26:27 CET 2013 1636.33 Mon Nov 18 11:26:27 CET 2013
10 - do not crash when freeing padlists with holes (in 5.18). 164 - do not crash when freeing padlists with holes (in 5.18).
11 - tentative SVt_BIND 5.19 port/fix. 165 - tentative SVt_BIND 5.19 port/fix.

117 was not good. thisone should be better. 271 was not good. this one should be better.
118 - check differently whether gcc generates cfi instructions itself. 272 - check differently whether gcc generates cfi instructions itself.

121 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be 275 - INCOMPATIBLE CHANGE: unreferenced coro objects will now be
122 destroyed and cleaned up automatically (e.g. async { schedule }). 276 destroyed and cleaned up automatically (e.g. async { schedule }).
123 - implement a JIT compiler for part of the thread switch code, 277 - implement a JIT compiler for part of the thread switch code,
124 which gives a 50% speed improvement on threaded perls, and 278 which gives a 50% speed improvement on threaded perls, and
125 about 4% on non-thraeded perls (so threaded perls now finally 279 about 4% on non-threaded perls (so threaded perls now finally
126 reach about half the speed of non-threaded perls). 280 reach about half the speed of non-threaded perls).
127 - slightly modernise Coro::Intro, add section about rouse functions. 281 - slightly modernise Coro::Intro, add section about rouse functions.
