michal 2026-01-09 12:16 developer ~0080274	Just correction - the marked byte is not frame size, it is byte with flags with Unsynchronisation bit set.

michal 2026-01-09 18:31 developer ~0080278	Fixed in build 3202. Now in such case, were Unsynchronisation bit is set, and parsing of the tags fails, we try to parse it as without Unsynchronisation bit (assuming, it is malformed file with this bit wrongly set). Please test mp3 tagging more, in case some regressions would appear, we would revert this library to the older one and finish this in v2026.

michal 2026-01-16 19:57 developer ~0080340	Should be ok in 3203. By some mistake the release contained wrong version of the DLL.

lowlander 2026-01-16 21:51 developer ~0080341	Verified in 3203, Artwork now shows
