19 - don't set diehook to C<undef> but instead to NULL, to avoid
20 spurious warnings.
21 - fix a lot of bugs in Coro::SemaphoreSet.
22 - Coro::SemaphoreSet will less often create a semaphore needlessly.
23 - add Coro::SemaphoreSet::count and wait methods.
24 - take advantage of the new Guard module.
25 - deprecate Coro::guard.

275.12 Sun Dec 7 13:30:38 CET 2008
28 - add default config for MirOS, which seems to be a bug-to-bug
29 compatible fork of openbsd ("world domination by releasing
30 openbsd cvs before the openbsd folks do it" or so :).
31 - free_padlist did destroy the names pad, not good, but didn't
32 seem to bother perl - this could fix issues such as eval ""
33 inside a function called from multiple coroutines.
34 - use a different method to detect destruction time.
35 - be more careful when freeing padlists just before global
36 destruction.
37 - fixed and expanded the call/cc example.
38 - renamed _terminate to _coro_run.
39 - new method Coro::Channel->shutdown.
40 - try pthreads on openbsd <4.4 (broken sigaltstack, will
41 pthreads fare better?).
42 - be less picky about destroying "a" running coroutine.

445.11 Tue Nov 25 21:49:05 CET 2008
45 - DEBUGGING in 5.10.0 is a mess: it constantly flags perfectly
46 working code with failed assertions, introducing more bugs than
47 it fixes, requiring elaborate workarounds :(

495.1 Mon Nov 24 08:54:59 CET 2008
50 - wrote a small introductory tutorial - Coro::Intro.
51 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
52 - Coro::Select did errornously dup the file descriptors
53 and didn't work with all AnyEvent backends.
54 - Coro::Select wasn't imported correctly form Coro::LWP, causing blocking
55 LWP data transfers.
56 - disassociate c contexts from coro objects - this is agruably more
57 correct, but mostly allows sharing of cctxs between coro and state
58 objects, for added memory savings and speed increases.
59 - bumped $Coro::POOL_RSS up to 32kb by default.
60 - no longer set the optype to OP_CUSTOM, as B::* understandably
61 doesn't like this very much (and we *are* a type of entersub).
62 - implement state cloning, just to prove that call/cc can be done.
63 - automatically load Coro::AnyEvent in Coro::Handle.
64 - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
65 do not have this method (and don't need it either).
66 - speed up generic anyevent methods in Coro::Handle by using rouse
67 callbacks.
68 - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
69 others. It also makes the debugger happier, as you can trace
70 through the idle threads now.
71 - add comppad_name* and hints ($^H, %^H) to per-thread variables.
72 - eg/event was pretty broken.
73 - better 5.8.6 compatibility.

20 - removed SemaphoreSet's waiter method - use sem instead. 82 - removed SemaphoreSet's waiter method - use sem method instead.

25 was waiting for a semaphore that was just becoming available 87 was waiting for a semaphore that was just becoming available
26 would cause a deadlock (semaphore would get into a state where 88 would cause a deadlock (semaphore would get into a state where
27 it was available but waiters were waiting(. 89 it was available but waiters were still blocked).
28 - calling throw on a coroutine that is waiting for a semaphore will 90 - 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). 91 no longer make it acquire the semaphore (and thus leak a count).
30 - perl's process emulation is now not even theoretically supported 92 - perl's process emulation is now not even theoretically supported
31 anymore. 93 anymore.
94 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
95 conversion of callback-style to blocking-style.
96 - new methods $coro->schedule_to and ->cede_to, to specifically
97 schedule or cede to a specific coroutine.
98 - new function Coro::Semaphore::wait.
32 - use named constants in Coro::Channel (Richard Hundt). 99 - use named constants in Coro::Channel (Richard Hundt).
33 - directly patch the entersub opcode calling SLF functions (cede, 100 - directly patch the entersub opcode calling SLF functions (cede,

49 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore, 116 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
50 for a nice speedup and vastly more correct behaviour. Also implement 117 for a nice speedup and vastly more correct behaviour. Also implement
51 a new method "sem" to get at the underlying semaphore object. 118 a new method "sem" to get at the underlying semaphore object.

53 (in comparison) 20-40% speedup. 120 (in comparison) 20-40% speedup.
121 - used new SLF interface to reimplement Coro::Signal gaining
122 some unknown (because I was too lazy), but certain, speedup, and also
123 making signals reliable for the first time.
124 - used new SLF interface and other optimisations to speed up async_pool
125 by a factor of two. It also doesn't rely on perl's exception mechanism
126 to exit anymore. The overhead for terminating an async_pool, coro over
127 a normal async is now very small.
128 - sped up coroutine creation/destruction by 40%.
54 - forgot to include Coro/libcoro/README in the dist for all these years. 129 - forgot to include Coro/libcoro/README in the dist for all these years.

56 pthread_cond_wait isn't a cancellation point on freebsd). 131 pthread_cond_wait isn't a cancellation point on freebsd).
132 - use new rouse functions to speed up and simplify Coro::BDB.
133 - make "prefer perl native functions" work with threaded perls.
134 - condense Coro::Debug ps output, hint at v and w flags.
135 - (libcoro) lots of minor cleanups and portability improvements.

139 introduced in 4.801.
