There have been three releases since our last update, so the
changes here span three changelogs:

* http://invisible-island.net/dialog/CHANGES.html#t20120703
* http://invisible-island.net/dialog/CHANGES.html#t20120706

p.s. I verified the GPG signature provided for the archive
against the public key on offer at the author's site:
