2.16.0 versus 2.15.95. Tiny differences in the dots on volta repeat
numbers. Nothing else. If anyone wants to see examples, please let me
know.
2.17.0 versus 2.16.0. Two major differences which aren't picked up by the
general regtest checker. 1) Fret diagrams - the line showing top of the
fret bar has changed in landscape mode. 2) Bookparts have lost their page
numbers. Unless anyone can convince me that these are deliberate, I'll
raise 2 critical regressions for them. See them at
http://www.philholmes.net/lilypond/regtestresults/2.17.0/2.17.1. The official regtest comparison is against 2.15.38, because of the
vagaries of my initial GUB build. This is spectacularly useless.... I'll
look at the regtests with my pixel comparator as soon as the upload of
2.17.1 has completed (so far, 4 hours and counting...)
