"Key Rotation" field name incorrect in interfaces.php
The "Key Rotation" field name from 2.2.x is listed as "WPA Pre-Shared Key" on 2.3.
Already fixed in 11439ca3d33849457dbc3b8bd2c00ac2b2667ceb, adding here for tracking.
I fixed the name to be more accurate "Group Key Rotation" and the help text now reflects group rekey, which will make correlating log events and settings easier. I made a few other edits for user-friendliness on the page as well.
