The new saved programId files are purely local, created and managed by the local user, and will not be impacted by installing a new distribution version. The behavior of known seriesId files, which are separate and distinct from the saved programId files, has not changed. Actually, saved programId files could be manually shared by users who trust each other. The shared file(s) would be placed in the "programIds" subfolder of MG3's appdata folder. Behavior would then be identical to the situation where the local user saved the file(s).
