Version Mp3tag v2.87a adds LAME MP3 encoder version- 'I've rewritten the code to analyze MP3s with this version (it was sooooo old) and added detection of LAME encoder versions while I was at it. You can access it via the %\_tool% information field, if this is something of interest to you'. Please indicate how you use the %\_tool% information field for LAME version detection. ---
