ExifTool::Vorbis NOTES variable conflict

[gcbond]

Hello,
I am using the Perl module of ExifTool 8.77 to retrieve FLAC/Vorbis information from a .flac music file. I receive  the error "Tag NOTES conflicts with internal ExifTool variable".  ExifTool still handles everything OK just rather a nuisance.  Just a heads up really.  I searched on the forum but didn't find any similar posts.
Here is a stack trace:

On another note do you think there will be any write support for MP3/M4A/FLAC tags in the future?

Thanks for this report.  This will be fixed in ExifTool 8.78.

About the write support:  It isn't very likely that this will be added in the foreseeable future.  I started adding ID3 write support a long while back but it was a real mess so it never got finished.  The ID3 specification is very poor, and it is very frustrating to implement.
