105.0
11 - NEW ARCHITECTURE: use the latest 4.x version if you experience
12 stability issues.
13 - bump API version to 7 - all dependents must be recompiled.
14 - removed timed_* functions - they were not being used anyways
15 and should be replaced by a more generic mechanism -
16 and were annoying to support anyways :)
17 - removed SemaphoreSet's waiter method - use sem instead.
18 - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
19 - async_pool did free a scalar value twice
20 ("Attempt to unreference...").
21 - fix a disastrous bug in the readline optimisation
22 introduced in 4.801.
23 - fix a longstanding bug where calling terminate on a coro that
24 was waiting for a semaphore that was just becoming available
25 would cause a deadlock (semaphore would get into a state where
26 it was available but waiters were still blocked).
27 - calling throw on a coroutine that is waiting for a semaphore will
28 no longer make it acquire the semaphore (and thus leak a count).
29 - perl's process emulation is now not even theoretically supported
30 anymore.
31 - new functions Coro::rouse_cb and Coro::rouse_wait.
32 - new function Coro::Semaphore::wait.
33 - use named constants in Coro::Channel (Richard Hundt).
34 - directly patch the entersub opcode calling SLF functions (cede,
35 transfer and so on). this does speed up context switching, but
36 more importanly, it frees us from the hardcoded behaviour of
37 entersub, so we might actually be able to return something from
38 those functions and atcually create new ones.
39 - take advantage of __builtin_frame_address on gcc.
40 - expose THX in coroapi (not sure whether this was a wise decision,
41 as "threaded" perls are running at half speed anyways).
42 - implement execute_slf (schedule-like-function) interface that makes
43 it possible to implement schedule-like-functions in XS.
44 - use new SLF interface to massively speed up Coro::EV by roughly a
45 factor of two.
46 - used new SLF interface to massively speed up Coro::Semaphore by a
47 factor of three.
48 - used new SLF interface to speed up Coro::AIO by roughly a factor of
49 four and reduce its memory usage considerably.
50 - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
51 for a nice speedup and vastly more correct behaviour. Also implement
52 a new method "sem" to get at the underlying semaphore object.
53 - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
54 (in comparison) 20-40% speedup.
55 - used new SLF interface to reimplement Coro::Signal gaining
56 some unknown (because I was too lazy), but certain, speedup, and also
57 making signals reliable for the first time.
58 - used new SLF interface and other optimisations to speed up async_pool
59 by a factor of two. It also doesn't rely on perl's exception mechanism
60 to exit anymore.
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 - async_pool did free a scalar value twice
72 ("Attempt to unreference...").
73
744.912 Thu Nov 13 18:31:23 CET 2008
75 - minor cleanups.
76 - use much larger stacks on linux and perl < 5.8.8.
77 - Coro::Debug::new_unix_server did not unlink the socket
78 when destroyed.
79
804.911 Tue Nov 11 04:26:17 CET 2008
81 - "port" to threaded perls.
82
834.91 Mon Nov 10 05:36:38 CET 2008
84 - the ->throw exception object no longer leaks.
85 - creating a new cctx leaked a scopestack entry (memleak).
86 - new coroutines didn't get created with a zero flags field
87 (unknown impact).
88 - calling ->throw on a not-yet-started coroutine should now work
89 instead of being ignored.
90 - ->throw is now supported on Coro::State objects.
91 - clean up cctx creation code a bit.
92 - entersub is actually a UNOP, not a LOGOP (not a bugfix).
93
944.9 Sat Nov 8 17:45:27 CET 2008
95 - (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
96 - (libcoro) no longer leak threads in the experimental pthread backend,
97 also speed it up considerably.
98 - (libcoro) do not rely on makecontext passing void *'s unscathed.
99 - fix compiletime dependencies on libcoro in the Makefile.
100 - cctx_count wasn't always updated properly.
101 - Coro::State::cctx_stacksize wasn't applied correctly.
102 - new function Coro::State::cctx_max_idle.
103 - the default max number of idle C contexts is now 4.
104 - (libcoro) try harder to get _setjmp/_longjmp.
105 - (libcoro) cleanup and extend the libcoro API to officially
106 allow the creation of empty source contexts.
107 - very experimental workaround for the totally broken netbsd platform.
108 - tried to hack around openbsd bugs.
109
1104.804 Wed Nov 5 16:36:00 CET 2008
111 - Coro::Debug::new_unix_server would not create a non-blocking listening
112 socket, sometimes causing freezes.
113 - (libcoro) fix misaligned stack points for setjmp and assembly
114 methods, which can cause crashes on x86/x86_64 with a sufficiently
115 aggressive compiler.
116 - new function: Coro::Debug::new_tcp_server.
117 - move ->throw into the Coro class because it only works on coro objects.
118
1194.803 Mon Nov 3 17:16:12 CET 2008
120 - (libcoro) use a global asm statement to become independent of gcc
121 otpimisations for CORO_ASM (thanks to pippijn for the idea).
122 - try to workaround yet another broken bsd, this time dragonfly.
123
1244.802 Thu Oct 30 10:56:12 CET 2008
125 - support -fno-omit-frame-pointer on x86 with the assembly method.
126 - tune 01_unblock.t tests a bit.
127
1284.801 Wed Oct 22 18:33:37 CEST 2008
129 - improve readline speed for very long "lines".
130 - backport to 5.8.8.
131
1324.8 Thu Oct 2 13:34:40 CEST 2008
133 - new function Coro::AIO::aio_wait.
134 - Coro.:AIO and Coro::BDB now "use Coro::AnyEvent".
135 - greatly speed up and reduce memory usage of Coro::AIO requests.
136 - implement some other ยต-optimisations.
