* Correct release notes. Based on report by Dennis Davis.
* Correct spellings in imap/Makefile. Contributed by Gerald Pfeifer. * Change comparison of ps_global->inbox_name from strcmp to strucmp in do_broach_folder. * When an invitation does not have a timezone in the date of the event, but the date is in GMT, adjust the date to local time.
