105.0 10 - add default config for MirOS, which seems to be a bug-to-bug
11 compatible fork of openbsd ("world domination by releasing
12 openbsd cvs before the openbsd folks do it" or so :).
13 - free_padlist did destroy the names pad, not good, but didn't
14 seem to bother perl - this could fix issues such as eval ""
15 inside a function called form multiple coroutines.
16 - use a different method to detect destruction time.
17 - be more careful when freeing padlists just before global
18 destruction.
19 - fixed and expanded the call/cc example.
20 - renamed _terminate to _coro_run.

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

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

31 - new functions Coro::rouse_cb and Coro::rouse_wait. 72 - new functions Coro::rouse_cb and Coro::rouse_wait for easier
73 conversion of callback-style to blocking-style.
74 - new methods $coro->schedule_to and ->cede_to, to specifically
75 schedule or cede to a specific coroutine.
32 - new function Coro::Semaphore::wait. 76 - new function Coro::Semaphore::wait.

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