The new generate_appcast tool automatically creates and updates appcast.xml files with DSA signatures and binary delta updates from a directory of archives.

./bin/generate_appcast path/to/your/private/dsa_key.pem update_downloads_folder/

The first argument for the tool is a DSA private key that must be corresponding to a DSA public key embedded in your app.

The second argument is a folder that should contain archived versions of your app bundle, e.g. example-app-1.2.zip, example-app-1.3.zip, etc.

The tool will read all information from the archives, e.g. read app versions and appcast URL from Info.plist of the archived apps.

It will generate (or update existing) appcast and create delta update files in the same directory. You can upload/rsync the entire directory to your server.

Note that the tool currently works only with regular .app bundles (i.e. not .pkg updates) and requires apps to use DSA signatures and have SUFeedURL in the Info.plist.

OS X 10.7 or later required

If you're not generating appcasts automatically, remember to add <sparkle:minimumSystemVersion>10.7</sparkle:minimumSystemVersion> tag to <item>s in your appcast. Sparkle will crash on Snow Leopard.
