This release corrects several defects in support for Flex Signature radios (tnx to Tom N9GUN, Kent N6WT, Pat K0PC, Joe WQ6Q, Peter HB9BUM, John K1ESE, and Rich N5ZC) - correctly conveys the transceiver frequency and mode to other applications - responds correctly when directed to QSY and set split If you don't use a Flex Signature transceiver, there is no reason to upgrade to this version, but doing so will not cause trouble.
