LilyPond 2.13.38 released; alpha test 4

LilyPond 2.13.38 is out; this is the fourth alpha test of the upcoming
2.14 stable release. Users are invited to experiment with this
version. New features since 2.12.3 are listed in the “Changes” manual
on the website section about Development.

There are still some Critical problems with this release: the vertical
spacing is suspicious in two cases, and lilypond can crash with some
odd input. If you decide to test 2.13.38, do not be surprised to
discover problems; just send us polite Bug reports.
