This version is a minor release with new options in the "Tools | Quick Personalization..." dialog. You can now use this dialog to install new spellcheckers or remove the spellcheckers you do not need:

There is also a change related to the "Backup Files" tool of Atlantis. If automatic creation of backup files is enabled, Atlantis may also create backups of its configuration file, Atlantis.ini, on close. You can use them to revert to a recent Atlantis configuration.
