10 - restore portability to perl 5.8.x.
11 - allow zero as agrument to Coro::Channel to mean the same thing
12 as no argument. this works with older versions as well,
13 but wasn't legal until now.
14
156.39 Mon Jun 2 00:00:08 CEST 2014
16 - work around more incompatible changes in 5.20.
17
186.38 Sun Jun 1 21:54:23 CEST 2014
19 - check that perl slots actually have enough space to hold
20 interpreter variables.
21 - untested port to perl 5.19 (64 bit tmps indices) (reported
22 by Andreas König).
23 - croak when cancel is called without a thread context.
24
256.37 Tue Mar 4 13:27:33 CET 2014
26 - *sigh*, removed leftover debugging code from debugging a
27 perl bug, of all things.
28
296.36 Tue Mar 4 07:11:59 CET 2014
30 - semaphores would not clear the destroy hook when interrupted
31 by ->throw, causing segfaults or worse.
32 - ->throw on a thread waiting for a semaphore did not acquire
33 the semaphore, but also didn't wake up other waiters,
34 possibly causing a deadlock.
35 - "FATAL: $Coro::IDLE blocked itself" will now use Carp::confess
36 to report a full stacktrace, which should help find out
37 where the actual call is.
38 - "atomically" destroy data in slf_destroy, because it is
39 the right thing to do, just in case.
40 - disable ecb.h libm dependency, to compile on ancient systems
41 or under adverse conditions.
42
436.33 Mon Nov 18 11:26:27 CET 2013
44 - do not crash when freeing padlists with holes (in 5.18).
45 - tentative SVt_BIND 5.19 port/fix.
46
476.32 Tue Nov 5 15:35:35 CET 2013
48 - use a new algorithm to derive padlists for perl 5.18. The old
49 one could lead to 0-pointer accesses inside perl (reported
50 by Darin McBride).
51
526.31 Thu May 9 07:39:48 CEST 2013
53 - Coro::AIO requests would crash if the thread was ready'd
54 while the request was ongoing.
55
566.29 Wed May 8 02:55:18 CEST 2013
57 - when an on_destroy handler destructs the coro currently being
58 destructed a perl scalar could be accessed after being freed,
59 likely causing a crash.
