14 stability issues. 11 stability issues.
15 - bump API version to 7 - all dependents must be recompiled. 12 - bump API version to 7 - all dependents must be recompiled.
13 - removed timed_* functions - they were not being used anyways
14 and should be replaced by a more generic mechanism -
15 and were annoying to support anyways :)
16 - removed SemaphoreSet's waiter method - use sem instead.
16 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 17 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
17 - async_pool did free a scalar value twice 18 - async_pool did free a scalar value twice

20 - fix a disastrous bug in the readline optimisation

20 was waiting for a semaphore that was just becoming available 23 was waiting for a semaphore that was just becoming available
21 would cause a deadlock (semaphore would get into a state where 24 would cause a deadlock (semaphore would get into a state where
22 it was available but waiters were waiting(. 25 it was available but waiters were still blocked).
26 - calling throw on a coroutine that is waiting for a semaphore will
27 no longer make it acquire the semaphore (and thus leak a count).
23 - perl's process emulation is now not even theoretically supported 28 - perl's process emulation is now not even theoretically supported
24 anymore. 29 anymore.
30 - new functions Coro::rouse_cb and Coro::rouse_wait.
31 - new function Coro::Semaphore::wait.
25 - use named constants in Coro::Channel (Richard Hundt). 32 - use named constants in Coro::Channel (Richard Hundt).
26 - directly patch the entersub opcode calling SLF functions (cede, 33 - directly patch the entersub opcode calling SLF functions (cede,
27 transfer and so on). this does speed up context switching, but 34 transfer and so on). this does speed up context switching, but

36 - use new SLF interface to massively speed up Coro::EV by roughly a 43 - use new SLF interface to massively speed up Coro::EV by roughly a
37 factor of two. 44 factor of two.
38 - removed timed_down and timed_guard functions - they were not being

41 - used new SLF interface to massively speed up Coro::Semaphore by a 45 - used new SLF interface to massively speed up Coro::Semaphore by a
42 factor of three. 46 factor of three.
43 - used new SLF interface to speed up Coro::AIO by roughly a factor of 47 - used new SLF interface to speed up Coro::AIO by roughly a factor of
44 four and reduce its memory usage considerably. 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 - used new SLF interface to reimplement Coro::Signal gaining
55 some unknown (because I was too lazy), but certain, speedup, and also
56 making signals reliable for the first time.
57 - sped up coroutine creation/destruction by 20%.
45 - forgot to include Coro/libcoro/README in the dist for all these years. 58 - forgot to include Coro/libcoro/README in the dist for all these years.

47 pthread_cond_wait isn't a cancellation point on freebsd). 60 pthread_cond_wait isn't a cancellation point on freebsd).
61 - use new rouse functions to speed up and simplify Coro::BDB.
62 - make "prefer perl native functions" work with threaded perls.
63 - condense Coro::Debug ps output, hint at v and w flags.
64 - (libcoro) lots of minor cleanups and portability improvements.
