-------
+- Issue #11306: mailbox in certain cases adapts to an inability to open
+ certain files in read-write mode. Previously it detected this by
+ checking for EACCES, now it also checks for EROFS.
+
- Issue #11265: asyncore now correctly handles EPIPE, EBADF and EAGAIN errors
on accept(), send() and recv().
