Do not install over 1.1 or a release older than that. You will more than likely face strange problems if you do. If you want to retain your old 1.1 installation, just install 1.2 into a new folder.

On Mac OS X and Linux/Unix, Snowberry now uses a different user home folder. On Mac OS X it is ~/Library/Application Support/Doomsday Engine and on Unix it is ~/.deng. If you have an existing Snowberry user home folder, you might consider copying its contents over to the new home folder.

A note about addons installed using the Addon Installer: since they are stored in your Snowberry folder, you will probably either want to manually copy them over to the new Snowberry home folder, or use the Addon Installer to install them from the old location.</noinclude>

• Manifests placed in the user addon folders are read as well.
• Fix Snowberry exceptions where the “C++ part of the ListBox object has been deleted”.

• Addon identifiers are formed so that they don't contain any reserved characters (spaces, parentheses).

• New logo graphics.
• English language updated with more accessible terminology: e.g., “Shared Settings” instead of “Defaults” profile, and “My Addon Folders” instead of “Custom Addon Folders”.
• When upgrading to Snowberry 1.2, some of the UI settings are automatically reset to the new defaults.

Your profiles and other files will then be saved to My Documents\Doomsday Frontend. By default, however, your profiles are saved under the snowberry folder in the location you installed Doomsday in.
• Plugin bundle structure improved so that the Python modules of the plugin are stored inside a Python package, which has its own namespace. See example.plugin in the repository for an example.
