I read the changelog and stumbled over

.
How about MP3?
Does MP3Tag also preserve uknown MP3 metadata (tag data) when writing tags?
Or are scenarios possible in which MP3Tag discards metadata it does not understand and is thus not a safe program?

There is _at least_ one [instance where MP3Tag deletes unknown MP3 metadata](https://community.mp3tag.de/t/10401/1): [**lyrics3**](http://www.id3.org/Lyrics3) and [**lyrics3v2**](http://www.id3.org/Lyrics3v2)
This isn't exactly confidence-building regarding the promise that MP3Tag wouldn't do the same thing with other metadata unknown to MP3Tag.
Why is this issue not being addressed?
