This is the initial release which adds support for UniFi VoIP phones (UVP).
**This version supports all UniFi hardware, UAP, USG, USW, & UVP.**
How to play safe?
UniFi stores everything under <UNIFI_BASE>/data/ . Keeping a copy will get your base covered. You can even install the new version, stop it, copy the data/ over it, and restart the controller.
