Why this update archive is not for the newest version official firmware?
The last official firmware is _20170612, but in this firmware is written about the update for _20170412
(this can be seen in the name of the archive)
I know that the _20170412 version has fewer features than the firmware _20170612
Why the update is not for firmware _20170612 ?
Where is the mistake ?
What firmware has the most complete functionality ?
