-	- NEW ARCHITECTURE: use 4.912 for the stable version.
+	- NEW ARCHITECTURE: use the latest 4.x version if you experience

         - 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 instead.
         - Coro::Semaphore->adjust didn't correctly wake up enough waiters.
         - async_pool did free a scalar value twice
           ("Attempt to unreference...").
+        - fix a disastrous bug in the readline optimisation
+          introduced in 4.801.
         - 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(.
+          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.
+        - 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

         - implement execute_slf (schedule-like-function) interface that makes
           it possible to implement schedule-like-functions in XS.

+        - 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.
         - 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.
+        - condense Coro::Debug ps output, hint at v and w flags.
+        - (libcoro) lots of minor cleanups and portability improvements.
