Please be aware there will be a one-time conversion of cached thumbnails and waveform data when you first run this
version. The old database will be kept so if you downgrade or run an older version you still have that older cache to
rely on. You can remove either db.sqlite3 (old) or thumbnails (new) in the app data directory to cleanup the old
cache or to re-run the conversion to the new file-based cache.
