Is this what you mean?
LilyPond 2.6 released - June 27, 2005
Version 2.6 is the latest stable release of LilyPond. It now installs in
a snap on Windows, MacOS X, and any version of Linux (x86). Get up and
running in minutes! Pango text formatting lets you print Unicode lyrics
in your favorite script and font. Create SVG files, and edit them in
Inkscape.

LilyPond 2.5.6 was released. This is a "technology preview" release,
which means that it has all kinds of nifty features, but is not actually
usable for producing nicely printed scores. For this reason, an RPM of
this release was not produced. The PS backend is now completely switched
over to Pango/FontConfig: for -f ps, LilyPond only accepts UTF8 input,
all text fonts are loaded through Pango, the TeX backend now offloads
all metric computations to LaTeX, the SVG and GNOME backends are broken,
most probably.
