# $Id$
Version 0.4.2 (latest)
Version 0.5.0-beta (latest)
* BACKWARD COMPATIBILITY BREAK: DNS TXT records now store their data in the new
DNSTXT attribute instead of the old DNScname attribute. You must manually
update any DNS TXT records for them to continue working.
Version 0.4.2
* Add SMF manifest
* Add manpage
* Ensure all options get initialized to defaults before any attempts at setting
