How to play safe?
Make sure you always do a backup before any updates, especially if you plan to upgrade your existing installation.
All system customizations are removed on firmware upgrade. This would include the UniFi VoIP controller, if you have it installed. Please make sure to backup your VoIP controller configuration, and any other customizations prior to firmware upgrade.
Changes in v0.5.0:
Bundle UniFi Controller 5.0.6. See HERE for controller release notes.
