Hi, you can set PDF metadata with a 'pdf' prefix as described in https://lilypond.org/doc/v2.23/Documentation/notation/creating-output-file-metadata
The PDF Creator should be set to LilyPond {version} even when setting an
author. I tested it here:
Author: Me
Creator: LilyPond 2.24.3
So this is not a bug. Questions about LilyPond usage are better asked on
[email protected].
Cheers
