125.0 18 - don't set diehook to C<undef> but instead to NULL, to avoid

21 - deprecate Coro::guard.

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

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

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

90 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
91 conversion of callback-style to blocking-style.

120 - used new SLF interface and other optimisations to speed up async_pool
121 by a factor of two. It also doesn't rely on perl's exception mechanism
122 to exit anymore. The overhead for terminating an async_pool, coro over
123 a normal async is now very small.
