Version History

Every release of Metadatics, from the initial 1.0 launch onward.

Version 1.8.1 - October 17, 2026

  • The track lists in the MusicBrainz window can now be sorted by track number, title, or length, and the new Match to Files button lines up the MusicBrainz tracks with your files by title and length.
  • Removing album artwork now shrinks the file instead of leaving the space the artwork used behind.
  • Fixed album artwork in Monkey’s Audio (APE) files: added artwork couldn’t be read back, and saving could erase artwork the file already had.
  • Fixed MusicBrainz writing the Year in the wrong numerals or calendar, or not at all, for some region and time zone settings.
  • Fixed the file list still showing the old names after Rename Files changed only the capitalization of a file name.
  • Files that Rename Files can’t rename are now reported in the Error Log.
  • Fixed a comment with many lines pushing the other fields in the General tab out of view.
  • Fixed Add Files not letting you choose a folder on macOS 27.

  • Fixed dialog buttons touching each other on macOS 26 and later.

Version 1.8.0 - September 30, 2026

  • Adding files now selects all of the newly added files.
  • Moving to the previous or next track with ⌘[ or ⌘] now keeps the field you were editing active.

  • Fixed several MP4/M4A tags — including ISRC, ASIN, and Mood — being saved in a form other apps don’t recognize and lost when re-saved. They are now written as standard iTunes atoms, and previously affected files repair themselves the next time you save.
  • Fixed MP4/M4A track number, disc number, and BPM being saved as the wrong value when set above 32767.
  • Fixed online album-artwork search returning wrong or no results for artists or titles containing “&” or “+” (for example “Simon & Garfunkel”).

  • Fixed missing progress and an incorrectly active toolbar while saving with “Save After Every Change” turned on.
