ID3v2.2 was the first version of the ID3v2 standard. ID3v2.3, ID3v2.4 standards have replaced ID3v2.2, so it is considered obsolete now.
The Tag Editor can parse, show tags in obsoleted ID3v1 and ID3v2.2 formats and save them in ID3v2.3 or ID3v2.4 formats. The steps, how to upgrade ID3v1 and ID3v2.2 tags in your MP3 files, have been provided below.
