+      TODO: Coro/Intro
+	- wrote a small introduction - Coro::Intro.
+	- convert Coro::Timer, Coro::Select and Coro::Util to rouse API.
+        - Coro::Select did errornously dup the file descriptors
+          and didn't work with all AnyEvent backends.
+        - disassociate c contexts from coro objects - this is agruably more
+          correct, but mostly allows sharing of cctxs between coro and state
+          objects, for added memory savings and speed increases.
+        - bumped $Coro::POOL_RSS up to 32kb by default.
+        - no longer set the optype to OP_CUSTOM, as B::* understandably
+          doesn't like this very much (and we *are* a type of entersub).
+        - implement state cloning, just to prove that call/cc can be done.
+        - automatically load Coro::AnyEvent in Coro::Handle.
+        - wrap ->cancel calls in eval inside Coro::Handle as EV watchers
+          do not have this method (and don't need it either).
+        - speed up generic anyevent methods in Coro::Handle by using rouse
+          callbacks.
+        - allow coroutines in $Coro::IDLE, speeding up Coro::AnyEvent and
+          others. It also makes the debugger happier, as you can trace
+          through the idle threads now.
+        - eg/event was pretty broken.
+        - better 5.8.6 compatibility.

+5.0  Thu Nov 20 10:35:05 CET 2008
 	- NEW ARCHITECTURE: use the latest 4.x version if you experience
           stability issues.
         - bump API version to 7 - all dependents must be recompiled.
+        - removed timed_* functions - they were not being used anyways
+          and should be replaced by a more generic mechanism -
+          and were annoying to support anyways :)
+        - removed SemaphoreSet's waiter method - use sem method instead.
         - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
         - async_pool did free a scalar value twice
           ("Attempt to unreference...").
         - fix a longstanding bug where calling terminate on a coro that
           was waiting for a semaphore that was just becoming available
           would cause a deadlock (semaphore would get into a state where
-          it was available but waiters were waiting(.
-        - avoid deadlock in Coro::Channel if maxsize == 1 (Richard Hundt).
+          it was available but waiters were still blocked).
+        - calling throw on a coroutine that is waiting for a semaphore will
+          no longer make it acquire the semaphore (and thus leak a count).
         - perl's process emulation is now not even theoretically supported
           anymore.
+        - new functions Coro::rouse_cb and Coro::rouse_wait for easier
+          conversion of callback-style to blocking-style.
+        - new methods $coro->schedule_to and ->cede_to, to specifically
+          schedule or cede to a specific coroutine.
+        - new function Coro::Semaphore::wait.
+        - use named constants in Coro::Channel (Richard Hundt).
         - directly patch the entersub opcode calling SLF functions (cede,
           transfer and so on). this does speed up context switching, but
           more importanly, it frees us from the hardcoded behaviour of

         - use new SLF interface to massively speed up Coro::EV by roughly a

         - used new SLF interface to speed up Coro::AIO by roughly a factor of
           four and reduce its memory usage considerably.
+        - implement Coro::SemaphoreSet purely in terms of Coro::Semaphore,
+          for a nice speedup and vastly more correct behaviour. Also implement
+          a new method "sem" to get at the underlying semaphore object.
+        - implement Coro::Channel in terms of Coro::Semaphore, for a moderate
+          (in comparison) 20-40% speedup.
+        - used new SLF interface to reimplement Coro::Signal gaining
+          some unknown (because I was too lazy), but certain, speedup, and also
+          making signals reliable for the first time.
+        - used new SLF interface and other optimisations to speed up async_pool
+          by a factor of two. It also doesn't rely on perl's exception mechanism
+          to exit anymore. The overhead for terminating an async_pool, coro over
+          a normal async is now very small.
+        - sped up coroutine creation/destruction by 40%.
         - forgot to include Coro/libcoro/README in the dist for all these years.
         - work around a freebsd pthreads bug (manual testcancel is required as
           pthread_cond_wait isn't a cancellation point on freebsd).
+        - use new rouse functions to speed up and simplify Coro::BDB.
+        - make "prefer perl native functions" work with threaded perls.
