135.0
14 - NEW ARCHITECTURE: use the latest 4.x version if you experience
15 stability issues.
16 - bump API version to 7 - all dependents must be recompiled.
17 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
18 - async_pool did free a scalar value twice
19 ("Attempt to unreference...").
20 - fix a longstanding bug where calling terminate on a coro that
21 was waiting for a semaphore that was just becoming available
22 would cause a deadlock (semaphore would get into a state where
23 it was available but waiters were waiting(.
24 - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt).
25 - perl's process emulation is now not even theoretically supported
26 anymore.
27 - directly patch the entersub opcode calling SLF functions (cede,
28 transfer and so on). this does speed up context switching, but
29 more importanly, it frees us from the hardcoded behaviour of
30 entersub, so we might actually be able to return something from
31 those functions and atcually create new ones.
32 - take advantage of __builtin_frame_address on gcc.
33 - expose THX in coroapi (not sure whether this was a wise decision,
34 as "threaded" perls are running at half speed anyways).
35 - implement execute_slf (schedule-like-function) interface that makes
36 it possible to implement schedule-like-functions in XS.
37 - use new SLF interface to massively speed up Coro::EV by roughly a
38 factor of two.
39 - removed timed_down and timed_guard functions - they were not being
40 used anyways and should be replaced by a more generic mechanism -
41 and were annoying to support anyways :)
42 - used new SLF interface to massively speed up Coro::Semaphore by a
43 factor of three.
44 - used new SLF interface to speed up Coro::AIO by roughly 400% and
45 reduce its memory usage considerably.
46 - forgot to include Coro/libcoro/README in the dist for all these years.
47 - work around a freebsd pthreads bug (manual testcancel is required as
48 pthread_cond_wait isn't a cancellation point on freebsd).

51 - async_pool did free a scalar value twice
52 ("Attempt to unreference...").
53
544.912 Thu Nov 13 18:31:23 CET 2008
55 - minor cleanups.
56 - use much larger stacks on linux and perl < 5.8.8.
57 - Coro::Debug::new_unix_server did not unlink the socket
58 when destroyed.
59
604.911 Tue Nov 11 04:26:17 CET 2008
61 - "port" to threaded perls.
62
634.91 Mon Nov 10 05:36:38 CET 2008
64 - the ->throw exception object no longer leaks.
65 - creating a new cctx leaked a scopestack entry (memleak).
66 - new coroutines didn't get created with a zero flags field
67 (unknown impact).
68 - calling ->throw on a not-yet-started coroutine should now work
69 instead of being ignored.
70 - ->throw is now supported on Coro::State objects.
71 - clean up cctx creation code a bit.
72 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
73
744.9 Sat Nov 8 17:45:27 CET 2008
75 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
76 - (libcoro) no longer leak threads in the experimental pthread backend,
77 also speed it up considerably.
78 - (libcoro) do not rely on makecontext passing void *'s unscathed.
79 - fix compiletime dependencies on libcoro in the Makefile.
80 - cctx_count wasn't always updated properly.
81 - Coro::State::cctx_stacksize wasn't applied correctly.
82 - new function Coro::State::cctx_max_idle.
83 - the default max number of idle C contexts is now 4.
84 - (libcoro) try harder to get _setjmp/_longjmp.
85 - (libcoro) cleanup and extend the libcoro API to officially
86 allow the creation of empty source contexts.
87 - very experimental workaround for the totally broken netbsd platform.
88 - tried to hack around openbsd bugs.
89
904.804 Wed Nov 5 16:36:00 CET 2008
91 - Coro::Debug::new_unix_server would not create a non-blocking listening
92 socket, sometimes causing freezes.
93 - (libcoro) fix misaligned stack points for setjmp and assembly
94 methods, which can cause crashes on x86/x86_64 with a sufficiently
95 aggressive compiler.
96 - new function: Coro::Debug::new_tcp_server.
97 - move ->throw into the Coro class because it only works on coro objects.
98

10 for CORO_ASM (thanks to pippijn for the idea). 101 otpimisations for CORO_ASM (thanks to pippijn for the idea).

14 - support -fno-omit-frame-pointer on x86 with the assembly method. 105 - support -fno-omit-frame-pointer on x86 with the assembly method.
15 - tune 01_unblock.t tests a bit. 106 - tune 01_unblock.t tests a bit.
