Lilypond 2.1.32 released

[Han-Wen Nienhuys]

Hiya!

Lily 2.1.32 is out. This release has more rewriting in the "Changing
defaults" chapter of the manual. Other than that, Jan has been working
like a madman to get optimal page-breaking in Lily. You can view
(preliminary) results by doing


export GS_LIB=LILYPOND-SOURCEDIR/mf/out:/usr/share/texmf/fonts/type1/bluesky/cm/
lilypond-bin -f ps -I input/mutopia/W.A.Mozart/ mozart-hrn-3.ly
gv mozart-hrn-3.ps

The default TeX output backend takes 5 pages.  As you can see, Lily
with the new backend will cramp the pages a bit to stuff the concerto
onto 4 pages.

The roadmap for the coming weeks is as follows: my plan is to finish
rewriting the manual chapter on "Changing Defaults" and release
version 2.2 after that (ETA: about one week).

The release criterion of LilyPond is that it has to be BugFree
(tm). This means:

* Whatever worked in 2.0 should remain to work.

* Bugs are undocumented deficiencies. Please report errors, so we can
  fix them or document them.

After 2.2 is out, we will start the 2.3 branch directly. In this
branch we will work on direct PostScript output (so we can drop the
silly lilypond.py script), --safe execution (run Lily over the
webserver!) and page layout (get sane page breaks in multi-piece
orchestral parts!).

Have fun!
