IQRF OS v3.09D
for TR-7xDx released. This is completely the same as v3.08D but the only feature is added – observing Israel local goverment restrictions regarding fixed RF band and limited range of RF channels. When upgrading to OS v3.09D, TR-7xDx-IL transceiver is created from TR-7xDx. OS downgrade from v3.09D is restricted. It is meaningless to migrate from OS v3.08D to v3.09D unless the application should be operated in Israel.
For new designs in Israel use OS v4.xxD.
