10TODO: Coro::Signal as SLF.
11 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt).

85.0 135.0
14 - NEW ARCHITECTURE: use the latest 4.x version if you experience
15 stability issues.
16 - bump API version to 7 - all dependents must be recompiled.
17 - removed timed_* functions - they were not being used anyways
18 and should be replaced by a more generic mechanism -
19 and were annoying to support anyways :)
20 - removed SemaphoreSet's waiter method - use sem instead.
21 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
22 - async_pool did free a scalar value twice
23 ("Attempt to unreference...").
24 - fix a longstanding bug where calling terminate on a coro that
25 was waiting for a semaphore that was just becoming available
26 would cause a deadlock (semaphore would get into a state where
27 it was available but waiters were waiting(.
28 - calling throw on a coroutine that is waiting for a semaphore will
29 no longer make it acquire the semaphore (and thus leak a count).
30 - perl's process emulation is now not even theoretically supported
31 anymore.
32 - use named constants in Coro::Channel (Richard Hundt).
33 - directly patch the entersub opcode calling SLF functions (cede,
34 transfer and so on). this does speed up context switching, but
35 more importanly, it frees us from the hardcoded behaviour of
36 entersub, so we might actually be able to return something from
37 those functions and atcually create new ones.
38 - take advantage of __builtin_frame_address on gcc.
39 - expose THX in coroapi (not sure whether this was a wise decision,
40 as "threaded" perls are running at half speed anyways).
41 - implement execute_slf (schedule-like-function) interface that makes
42 it possible to implement schedule-like-functions in XS.
43 - use new SLF interface to massively speed up Coro::EV by roughly a
44 factor of two.
45 - used new SLF interface to massively speed up Coro::Semaphore by a
46 factor of three.
47 - used new SLF interface to speed up Coro::AIO by roughly a factor of
48 four and reduce its memory usage considerably.
49 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
50 for a nice speedup and vastly more correct behaviour. Also implement
51 a new method "sem" to get at the underlying semaphore object.
52 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
53 (in comparison) 20-40% speedup.
54 - forgot to include Coro/libcoro/README in the dist for all these years.
55 - work around a freebsd pthreads bug (manual testcancel is required as
56 pthread_cond_wait isn't a cancellation point on freebsd).

59 - async_pool did free a scalar value twice
60 ("Attempt to unreference...").

624.912 Thu Nov 13 18:31:23 CET 2008
63 - minor cleanups.
64 - use much larger stacks on linux and perl < 5.8.8.
65 - Coro::Debug::new_unix_server did not unlink the socket
66 when destroyed.
67
684.911 Tue Nov 11 04:26:17 CET 2008
69 - "port" to threaded perls.
70
714.91 Mon Nov 10 05:36:38 CET 2008
72 - the ->throw exception object no longer leaks.
73 - creating a new cctx leaked a scopestack entry (memleak).
74 - new coroutines didn't get created with a zero flags field
75 (unknown impact).
76 - calling ->throw on a not-yet-started coroutine should now work
77 instead of being ignored.
78 - ->throw is now supported on Coro::State objects.
79 - clean up cctx creation code a bit.
80 - entersub is actually a UNOP, not a LOGOP (not a bugfix).

90 - new function Coro::State::cctx_max_idle.
91 - the default max number of idle C contexts is now 4.
