16 stability issues. 10 stability issues.
17 - bump API version to 7 - all dependents must be recompiled. 11 - bump API version to 7 - all dependents must be recompiled.
12 - removed timed_* functions - they were not being used anyways
13 and should be replaced by a more generic mechanism -
14 and were annoying to support anyways :)
15 - removed SemaphoreSet's waiter method - use sem instead.
18 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 16 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.

23 would cause a deadlock (semaphore would get into a state where 21 would cause a deadlock (semaphore would get into a state where
24 it was available but waiters were waiting(. 22 it was available but waiters were still blocked).
25 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt). 23 - calling throw on a coroutine that is waiting for a semaphore will
24 no longer make it acquire the semaphore (and thus leak a count).
26 - perl's process emulation is now not even theoretically supported 25 - perl's process emulation is now not even theoretically supported
27 anymore. 26 anymore.
27 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
28 conversion of callback-style to blocking-style.
29 - new methods $coro->schedule_to and ->cede_to, to specifically
30 schedule or cede to a specific coroutine.
31 - new function Coro::Semaphore::wait.
32 - use named constants in Coro::Channel (Richard Hundt).
28 - directly patch the entersub opcode calling SLF functions (cede, 33 - directly patch the entersub opcode calling SLF functions (cede,
29 transfer and so on). this does speed up context switching, but 34 transfer and so on). this does speed up context switching, but

38 - 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
39 factor of two. 44 factor of two.

44 factor of three. 46 factor of three.
45 - 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
46 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 - used new SLF interface and other optimisations to speed up async_pool
58 by a factor of two. It also doesn't rely on perl's exception mechanism
59 to exit anymore. The overhead for terminating an async_pool, coro over
60 a normal async is now very small.
61 - sped up coroutine creation/destruction by 40%.
47 - forgot to include Coro/libcoro/README in the dist for all these years. 62 - forgot to include Coro/libcoro/README in the dist for all these years.

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