wrong version in installer?

[V!ictor address@hidden]

Hello all,

I just downloaded Lilypond v. 2.9.13-1 for windows from 
http://download.linuxaudio.org/lilypond/binaries/mingw/lilypond-2.9.13-1.mingw.exe

to try out the new proportional grace notes feature, but after installing and 
running
lilypond -v 

i get version 2.9.12...


I tried running the following code anyway:

% code %%%%%%%%%%%%%%%%%%%%%%%%%%%5

\relative c''
{
        \override Score.GraceSpacing #'spacing-increment = #2.0
        c4
        \grace{c16 c8 c32}
        c4
        \grace{c16[ d e f]}

}

% end code %%%%%%%%%%%%%%%%%%%%%%%%

but i got the following error:

grace_proportional.ly:22:0: warning: not a grob name, 'GraceSpacing'
[1]erride Score.GraceSpacing #'spacing-increment = #2.0

The lilypond reference for 2.9 now shows that GraceSpacing grobs now exist. 
Does the installer have the wrong version? (v.2.9.12 instead of v.2.9.13) or am 
I doing something wrong?


thanks,

VA.
