8 - convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
9 - Coro::Select did errornously dup the file descriptors
10 and didn't work with all AnyEvent backends.
11 - bumped $Coro::POOL_RSS up to 32kb by default.
12 - no longer set the optype to OP_CUSTOM, as B::* understandably
13 doesn't like this very much (and we *are* a type of entersub).
14 - better 5.8.6 compatibility.

165.0 Thu Nov 20 10:35:05 CET 2008
17 - NEW ARCHITECTURE: use the latest 4.x version if you experience
18 stability issues.
19 - bump API version to 7 - all dependents must be recompiled.
20 - removed timed_* functions - they were not being used anyways
21 and should be replaced by a more generic mechanism -
22 and were annoying to support anyways :)
23 - removed SemaphoreSet's waiter method - use sem method instead.
24 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
25 - async_pool did free a scalar value twice
26 ("Attempt to unreference...").
27 - fix a longstanding bug where calling terminate on a coro that
28 was waiting for a semaphore that was just becoming available
29 would cause a deadlock (semaphore would get into a state where
30 it was available but waiters were still blocked).
31 - calling throw on a coroutine that is waiting for a semaphore will
32 no longer make it acquire the semaphore (and thus leak a count).
33 - perl's process emulation is now not even theoretically supported
34 anymore.
35 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
36 conversion of callback-style to blocking-style.
37 - new methods $coro->schedule_to and ->cede_to, to specifically
38 schedule or cede to a specific coroutine.
39 - new function Coro::Semaphore::wait.
40 - use named constants in Coro::Channel (Richard Hundt).
41 - directly patch the entersub opcode calling SLF functions (cede,
42 transfer and so on). this does speed up context switching, but
43 more importanly, it frees us from the hardcoded behaviour of
44 entersub, so we might actually be able to return something from
45 those functions and atcually create new ones.
46 - take advantage of __builtin_frame_address on gcc.
47 - expose THX in coroapi (not sure whether this was a wise decision,
48 as "threaded" perls are running at half speed anyways).
49 - implement execute_slf (schedule-like-function) interface that makes
50 it possible to implement schedule-like-functions in XS.
51 - use new SLF interface to massively speed up Coro::EV by roughly a
52 factor of two.
53 - used new SLF interface to massively speed up Coro::Semaphore by a
54 factor of three.
55 - used new SLF interface to speed up Coro::AIO by roughly a factor of
56 four and reduce its memory usage considerably.
57 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
58 for a nice speedup and vastly more correct behaviour. Also implement
59 a new method "sem" to get at the underlying semaphore object.
60 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
61 (in comparison) 20-40% speedup.
62 - used new SLF interface to reimplement Coro::Signal gaining
63 some unknown (because I was too lazy), but certain, speedup, and also
64 making signals reliable for the first time.
65 - used new SLF interface and other optimisations to speed up async_pool
66 by a factor of two. It also doesn't rely on perl's exception mechanism
67 to exit anymore. The overhead for terminating an async_pool, coro over
68 a normal async is now very small.
69 - sped up coroutine creation/destruction by 40%.
70 - forgot to include Coro/libcoro/README in the dist for all these years.
71 - work around a freebsd pthreads bug (manual testcancel is required as
72 pthread_cond_wait isn't a cancellation point on freebsd).
73 - use new rouse functions to speed up and simplify Coro::BDB.
74 - make "prefer perl native functions" work with threaded perls.
75 - condense Coro::Debug ps output, hint at v and w flags.
76 - (libcoro) lots of minor cleanups and portability improvements.

79 - fix a disastrous bug in the readline optimisation
80 introduced in 4.801.
81
824.913 Sat Nov 15 07:58:28 CET 2008
83 - async_pool did free a scalar value twice
84 ("Attempt to unreference...").
85
864.912 Thu Nov 13 18:31:23 CET 2008
87 - minor cleanups.
88 - use much larger stacks on linux and perl < 5.8.8.
89 - Coro::Debug::new_unix_server did not unlink the socket
90 when destroyed.
91
924.911 Tue Nov 11 04:26:17 CET 2008
93 - "port" to threaded perls.
94
954.91 Mon Nov 10 05:36:38 CET 2008
96 - the ->throw exception object no longer leaks.
97 - creating a new cctx leaked a scopestack entry (memleak).
98 - new coroutines didn't get created with a zero flags field
99 (unknown impact).
100 - calling ->throw on a not-yet-started coroutine should now work
101 instead of being ignored.
102 - ->throw is now supported on Coro::State objects.
103 - clean up cctx creation code a bit.
104 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
105
1064.9 Sat Nov 8 17:45:27 CET 2008
107 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
108 - (libcoro) no longer leak threads in the experimental pthread backend,
109 also speed it up considerably.
110 - (libcoro) do not rely on makecontext passing void *'s unscathed.
111 - fix compiletime dependencies on libcoro in the Makefile.
112 - cctx_count wasn't always updated properly.
113 - Coro::State::cctx_stacksize wasn't applied correctly.
114 - new function Coro::State::cctx_max_idle.
115 - the default max number of idle C contexts is now 4.
116 - (libcoro) try harder to get _setjmp/_longjmp.
117 - (libcoro) cleanup and extend the libcoro API to officially
118 allow the creation of empty source contexts.
119 - very experimental workaround for the totally broken netbsd platform.
120 - tried to hack around openbsd bugs.
