And as far as I understood this is the version that will automatically be updated for all phones, i.e. it’s the update that will get 15.04 phones to 16.04 via the standard update mechanism.
Correct !
However, automatically updating UT needs the UBPorts recovery, so for my FP2 I’ll go through the installer instead (NOT checking “wipe” option) as I have TWRP as recovery
