New items should be added to the top of the list so the last entry here is the oldest. The order of each entry should be [code]definename[/code] followed by the original text of the documentation, ending with a separate paragraph "REMOVED [version] [replacement or reason for removal]".
REMOVED 1.0.0-RC2 initial sync replaced with a full FHSS period wait
#DARM_CHANNELas AUX1 which is Channel 5).
NB This feature assumes that a low value of the arm switch is disarmed, and a high value is armed. If you have the arm switch reversed it will not work correctly and the link won't be established. For this reason it may be best not to enable no sync on arm when you are first setting up ExpressLRS as it can be a source of confusion.
REMOVED 1.0.0-RC1 AUX1 is always the arm switch now, no longer configurable
LOCK_ON_50HZlocks the RX at
50Hzmode from the powerup. (Only recommended for longrange, and partly redundant with previous feature.) Merged in Pull 143
REMOVED 1.0.0-RC1 not sure why this was removed
