* fix a problem in sed logic for commenting out disabled options (closes: #689296) * support "EXTERNAL" SASL mechanism in debconf configuration (LP: #1063923) (the debconf template has been postponed to avoid having to update all translations for a relatively minor change) * 01-use-poll-instead-of-select.patch: use poll() instead of select() for checking file descriptor activity to also correctly work if more than FD_SETSIZE files are already open (closes: #690319)
