Pocket Wizard today announced firmware update version 3.7 for their MiniTT1 and FlexTT5 transmitter and receivers. The update now fully supports a number of recent Nikon cameras (D610, D810, Df, D4s, D3300, D5200, D5300, and D7100), plus includes some small fixes to the previous version.
Note that when you update your Pocket Wizards, you need to make sure everything is on the same firmware release, and you should perform a factory reset of the radio after the update to insure that it comes up correctly.
