 - **ID3v2**: Support parsing UTF-16 `COMM`/`USLT` frames with a single BOM ([issue](https://github.com/Serial-ATA/lofty-rs/issues/532)) ([PR](https://github.com/Serial-ATA/lofty-rs/pull/535))
   - Some encoders will only write a BOM to the frame's description, rather than to every string in the frame.
     This was previously only supported in `SYLT` frames, and has been extended to `COMM` and `USLT`.
+- **Vorbis Comments**: Parse `TRACKNUMBER` with respect to `ParseOptions::implicit_conversions` ([issue](https://github.com/Serial-ATA/lofty-rs/issues/540)) ([PR](https://github.com/Serial-ATA/lofty-rs/issues/542))
