LilyPond 2.3.7 is out

LilyPond 2.3.7 is available.

I have been rather disappointed with the user response on the 2.3
series release. In fact, one of our regular contributor was recently
seen recommending 2.2 over 2.3. This is, of course, heresy.  Real
musicians run their daily update from unstable CVS.  For those that
need to finish actual work, we have the weekly 2.3.x release.

To spur the adoption of LilyPond 2.3, I have decided to give 2.3 yet
another bonus-point over 2.2. The latest development release sports
the long-awaited rewrite of the slur code.

Slurs will now avoid collisions with fingerings, accents, accidentals.
The positioning is better for heavily tilted slurs. In complex
situations, a better compromise between conflicting requirements is
taken. Of course, it produces perfectly shaped slurs, so its not a
great loss that old Slur tweaking code (eg. #'attachment tuning) has no
effect whatsoever.

In the meantime, Jan has been preparing for sleepless nights to come
by rewriting our build system. Hopefully, we will switch LilyPond to
Scons (www.scons.org) in the near future, thus obviating the baroque
counterpoint of autoconf, make, stepmake and libtool.

Other attractions are more fret-diagram updates by Carl, David
Svoboda's ultra nifty what-beat function for LilyPond, and bunch of
bugfixes.



NEWS:

   * Slur formatting has been rewritten. The new slur code works
     similar to the Beam formatter: scores are assigned for all
     esthetic components of a slur. A large number of combinations for
     begin and end points is then tried out.  Slurs will now also take
     into account collisions with staff lines, scripts (like staccato
     and accent) and accidentals.

   * In the LilyPond  emacs mode, the `|' will now display the
     current beat within the measure.
