This version is a minor release with important changes regarding the Atlantis settings. From this version on, Atlantis does not store its settings in the Windows Registry anymore. The Atlantis settings are now stored in the INI file. You can normally find it under the "My documents\Atlantis" folder. If there is no INI file in your system yet, this version of Atlantis automatically retrieves the Atlantis settings from the Windows Registry, if available, and generates the INI file on close.
