Beta releases will be included in the Spark auto-update process.
- Users must opt-in through a Spark setting in the preferences window
- The setting is a checkbox in the "Notifications" pane in the preferences window that reads "Check for Beta Updates"
- The default is unchecked
- When enabled, Spark checks for both beta releases and normal releases
- If a new release is available the user is prompted to upgrade, just like it currently works with general releases of Spark
