LilyPond 2.1.17 released

2.1.17 is out.  This release now also prints "a2" and "solo" texts for
    part combinining, which means that it should now be practically
    usable. It also resurrects the --safe option, which prevents
    malicious Scheme code from being executed.

NEWS:

  * The ergonomic syntax of `\markup' now has an equivalent in Scheme.
     The `markup*' macro creates such objects; the following two markup
     commands are equivalent:
           f4^#(markup* #:raise 0.2 #:bold "hi")
           f4^\markup { \raise #0.2 \bold hi  }

 * Safe mode has been reinstated for lilypond.  When lilypond is
     invoked with `--safe-mode', TeX and PostScript file output is
     disallowed, and lilypond-bin is invoked with `--safe-mode', the
     user's Guile expressions are evaluated in a safe environment and
     file inclusion is not allowed.

     Be warned that a DOS attack using Guile, TeX or PostScript is
     rather easy.

     (This feature is still experimental.)
