+5.0
+	- NEW ARCHITECTURE: use the latest 4.x version if you experience
+          stability issues.
+        - bump API version to 7 - all dependents must be recompiled.
+        - 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).
+        - perl's process emulation is now not even theoretically supported
+          anymore.
+        - 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.
+        - removed timed_down and timed_guard functions - they were not being
+          used anyways and should be replaced by a more generic mechanism -
+          and were annoying to support anyways :)
+        - 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.
+        - 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).
+
+4.913 Sat Nov 15 07:58:28 CET 2008
+        - async_pool did free a scalar value twice
+          ("Attempt to unreference...").
+
+4.912 Thu Nov 13 18:31:23 CET 2008
+	- minor cleanups.
+        - use much larger stacks on linux and perl < 5.8.8.
+        - Coro::Debug::new_unix_server did not unlink the socket
+          when destroyed.
+
+4.911 Tue Nov 11 04:26:17 CET 2008
+	- "port" to threaded perls.
+
+4.91 Mon Nov 10 05:36:38 CET 2008
+        - the ->throw exception object no longer leaks.
+        - creating a new cctx leaked a scopestack entry (memleak).
+	- new coroutines didn't get created with a zero flags field
+          (unknown impact).
+	- calling ->throw on a not-yet-started coroutine should now work
+          instead of being ignored.
+        - ->throw is now supported on Coro::State objects.
+        - clean up cctx creation code a bit.
+        - entersub is actually a UNOP, not a LOGOP (not a bugfix).
+
+4.9  Sat Nov  8 17:45:27 CET 2008
+ 	- (libcoro) did not preserve rbp with CORO_ASM (we are getting there).
+        - (libcoro) no longer leak threads in the experimental pthread backend,
+          also speed it up considerably.
+        - (libcoro) do not rely on makecontext passing void *'s unscathed.
+        - fix compiletime dependencies on libcoro in the Makefile.
+        - cctx_count wasn't always updated properly.
+        - Coro::State::cctx_stacksize wasn't applied correctly.
+        - new function Coro::State::cctx_max_idle.
+        - the default max number of idle C contexts is now 4.
+        - (libcoro) try harder to get _setjmp/_longjmp.
+        - (libcoro) cleanup and extend the libcoro API to officially
+          allow the creation of empty source contexts.
+        - very experimental workaround for the totally broken netbsd platform.
+        - tried to hack around openbsd bugs.
+
+4.804 Wed Nov  5 16:36:00 CET 2008
+	- Coro::Debug::new_unix_server would not create a non-blocking listening
+          socket, sometimes causing freezes.
+        - (libcoro) fix misaligned stack points for setjmp and assembly
+          methods, which can cause crashes on x86/x86_64 with a sufficiently
+          aggressive compiler.
+        - new function: Coro::Debug::new_tcp_server.
+	- move ->throw into the Coro class because it only works on coro objects.
+
+4.803 Mon Nov  3 17:16:12 CET 2008
+	- (libcoro) use a global asm statement to become independent of gcc
+          otpimisations for CORO_ASM (thanks to pippijn for the idea).
+        - try to workaround yet another broken bsd, this time dragonfly.
+
+4.802 Thu Oct 30 10:56:12 CET 2008
+        - support -fno-omit-frame-pointer on x86 with the assembly method.
+	- tune 01_unblock.t tests a bit.
+
 4.801 Wed Oct 22 18:33:37 CEST 2008
 	- improve readline speed for very long "lines".
 	- backport to 5.8.8.
