Does editing tags change the audio?

No. Only the ID3 metadata frame is rewritten. The audio frames are copied byte-for-byte.

Which ID3 versions are supported?

Reads ID3v2.3, v2.4, and v1. Writes ID3v2.3, which every modern player accepts.

Not yet — this release focuses on the text fields. Cover-art writing is on the roadmap.
