A new version of MIDI2LR is available at https://github.com/rsjaffe/MIDI2LR/releases .
See https://github.com/rsjaffe/MIDI2LR/wiki/Version-History for version history.
Because of one missing negation sign in versions 3.4.9 through 3.5.0.2, the version update checker doesn't work in those versions, and will not automatically notify you of updates. If you know others who have MIDI2LR and might have those versions, please give them a notice too.
