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

48 for a nice speedup and vastly more correct behaviour. Also implement 52 for a nice speedup and vastly more correct behaviour. Also implement
49 a new method "sem" to get at the underlying semaphore object. 53 a new method "sem" to get at the underlying semaphore object.

51 (in comparison) 20-40% speedup. 55 (in comparison) 20-40% speedup.
56 - used new SLF interface to reimplement Coro::Signal gaining
57 some unknown (because I was too lazy), but certain, speedup, and also
58 making signals reliable for the first time.
59 - used new SLF interface and other optimisations to speed up async_pool
60 by a factor of two. It also doesn't rely on perl's exception mechanism
61 to exit anymore. The overhead for terminating an async_pool, coro over
62 a normal async is now very small.
63 - sped up coroutine creation/destruction by 40%.
52 - forgot to include Coro/libcoro/README in the dist for all these years. 64 - forgot to include Coro/libcoro/README in the dist for all these years.

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