+	- INCOMPATIBLE CHANGE: unreferenced coro objects will now be
+          destroyed and cleaned up automatically (e.g. async { schedule }).
+        - Coro::State->is_destroyed is now called is_zombie.
         - croak when a coro that is being cancelled tries to block
           (e.g. while executing a guard block), instead of crashing or
           deadlocking.
