I'd keep the version in sync with the stable release, but I guess 
that's up to the maintainer. The documentation says that "Every 
LilyPond file should contain a version statement":

The version statement is important for at least two reasons. 
First, it allows automatic updating of the input file as LilyPond 
syntax changes. Second, it describes the version of LilyPond 
needed to compile the file.

If the version statement is omitted from an input file, LilyPond 
prints a warning during the compilation of the file.
