This is a beta release. The database will be migrated. Sync protocol has been updated which means all instances in sync cluster must be updated as well.

The main feature of this release is configurable left launchbar. You can open it in Main Menu -> Configure Launchbar. There you can drag & drop launchers between visible and available, create new launchers etc. To make this happen, a lot of foundational work has been done on the "hidden subtree" which will be leveraged in the future.

Backwards incompatible changes

Deprecated TabAwareWidget, TabCachingWidget and NoteContextCachingWidget have been removed. Please change your widgets to extend NoteContextAwareWidget (this change should generally not need any refactoring).

Frontend API's addButtonToToolbar() has been deprecated. The API still works - it creates a launcher, but it may be misplaced. The launcher order can be configured via GUI (Main Menu -> Configure Launchbar). The same place should be used to create new launchers.
