+TODO: Coro::Signal as SLF.

 5.0
-	- NEW ARCHITECTURE: use 4.912 for the stable version.
+	- NEW ARCHITECTURE: use the latest 4.x version if you experience
+          stability issues.
         - bump API version to 7 - all dependents must be recompiled.
-        - directly patch the entersub opcode calling ssl functions (cede,
-          transfer and so on). this does speed up context switching by
-          up to 10%. More importanly, it frees us from the hardcoded
-          behaviour of entersub, so we might actually be able to return
-          something from those functions.
-        - take advanatge of __builtin_frame_address on gcc.
-        - expose THX in coroapi (not sure whether this was a wise decision).
+        - 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 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(.
+        - perl's process emulation is now not even theoretically supported
+          anymore.
+        - 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
+          entersub, so we might actually be able to return something from
+          those functions and atcually create new ones.
+        - take advantage of __builtin_frame_address on gcc.
+        - expose THX in coroapi (not sure whether this was a wise decision,
+          as "threaded" perls are running at half speed anyways).
+        - implement execute_slf (schedule-like-function) interface that makes
+          it possible to implement schedule-like-functions in XS.
+        - use new SLF interface to massively speed up Coro::EV by roughly a
+          factor of two.
+        - used new SLF interface to massively speed up Coro::Semaphore by a
+          factor of three.
+        - 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.
+        - 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).
