Updates are free, with or without Pro. The Mac app checks for a new version by itself once a day and asks before installing anything; you can also use Settings › About › Check for Updates. The Windows app tells you by itself when a new version is out. The page that opens when you click Download for Mac or Download for Windows shows the current version. Updating never touches your recordings, transcripts, voiceprints or license.
