I've just released **Mp3tag for Mac v1.4.3** with the following changes:

**New**

- Added support for importing `ISRC` — International Standard Recording Codes — via MusicBrainz tag source.
- Added `BARCODE` and `CATALOGNUMBER` to default list of fields.

**Changed, Improved & Fixed:**

- Changed Discogs and MusicBrainz tag sources to use `CATALOGNUMBER` instead of `CATALOGID` to improve compatibility with other software.
- Added workaround for non-null padding bytes for INFO subchunks in WAV and AIF.
- Action case conversion had no effect on directory name.
- Externally renamed folders with capitalization-only changes used previous capitalization on reload.
