9 - NEW ARCHITECTURE: use 4.912 for the stable version. 9 - NEW ARCHITECTURE: use the latest 4.x version if you experience
10 stability issues.
10 - 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 method instead.
11 - Coro::Semaphore->adjust didn't correctly wake up enough waiters. 16 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
12 - async_poll did free a scalar value twice. 17 - async_pool did free a scalar value twice
18 ("Attempt to unreference...").
19 - fix a longstanding bug where calling terminate on a coro that
20 was waiting for a semaphore that was just becoming available
21 would cause a deadlock (semaphore would get into a state where
22 it was available but waiters were still blocked).
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).
13 - perl's process emulation is now not even theoretically supported 25 - perl's process emulation is now not even theoretically supported
14 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).
15 - directly patch the entersub opcode calling SLF functions (cede, 33 - directly patch the entersub opcode calling SLF functions (cede,
16 transfer and so on). this does speed up context switching, but 34 transfer and so on). this does speed up context switching, but
17 more importanly, it frees us from the hardcoded behaviour of 35 more importanly, it frees us from the hardcoded behaviour of
18 entersub, so we might actually be able to return something from 36 entersub, so we might actually be able to return something from
19 those functions and atcually create new ones. 37 those functions and atcually create new ones.
20 - take advantage of __builtin_frame_address on gcc. 38 - take advantage of __builtin_frame_address on gcc.
21 - expose THX in coroapi (not sure whether this was a wise decision, 39 - expose THX in coroapi (not sure whether this was a wise decision,
22 as "threaded" perls are running at half speed anyways). 40 as "threaded" perls are running at half speed anyways).
23 - implement execute_slf (schedule-like-function) interface that makes 41 - implement execute_slf (schedule-like-function) interface that makes
24 it possible to implement schedule-like-functions in XS. 42 it possible to implement schedule-like-functions in XS.
25 - use new SLF interface to massively speed up Coro::EV (it's roughly 43 - use new SLF interface to massively speed up Coro::EV by roughly a
26 twice as fast now). 44 factor of two.
27 - removed timed_down and timed_guard functions - they were not being used 45 - used new SLF interface to massively speed up Coro::Semaphore by a
28 anyways and should be replaced by a more generic mechanism. 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 - 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%.
62 - forgot to include Coro/libcoro/README in the dist for all these years.
63 - work around a freebsd pthreads bug (manual testcancel is required as
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.

71 - fix a disastrous bug in the readline optimisation
72 introduced in 4.801.

75 - async_pool did free a scalar value twice

32 - use much larger stacks on linux and perl < 5.8.8. 80 - use much larger stacks on linux and perl < 5.8.8.
