It appears that with iTunes (December '16), Apple introduced a new ID3v2 frame 'GRP1', outside of the official ID3 spec.

The 'GRP1' seems to be the new place where iTunes writes its 'grouping' information. That information was previously written to 'TIT1'.

The most recent release of TagLip is predates this development.

Are there plans to support this new frame in a future TagLib release?

If I want to add read /write support to my local TagLib code, what would be the best approach?
