Hi All,
As you know Liberation 2.0 is one of the feature of Fedora 18. Recent analysis and comparison with Liberation 1 it is more clear that final output of Liberation 2.0 is not as sharp as it was with Liberation 1.0. Though both are from same vendor (Ascender Corporation) hinting bytecodes are different.
Liberation2 already available in Fedora18 Beta, if one wants to install both fonts simultaneously Download [1] has liberation ttf with different family name, so one can have both version same time on Fedora. (cp to /usr/share/fonts/liberation and then fc-cache)
https://bugzilla.redhat.com/show_bug.cgi?id=856239 , though bugzilla has more than 100 comments but if someone see to the attached screenshot will be sufficient for review.
I did comparison of Fedora output with Windows7 as well. But on Windows results are totally different than Fedora.
On Fedora 18 : http://pravins.fedorapeople.org/liberation/arial-sans2-sans1-arimo-testing2-fedora18.png (Here Sans2 = Liberation2 , San1 = Liberation1 and Arimo = Google Croscore)

On Fedora 18 : http://pravins.fedorapeople.org/liberation/arial-sans2-sans1-arimo-testing2-fedora18-subpixel-rendering.png (with freetype-freeworld Xft.antialias: 1
Xft.dpi: 96
Xft.hinting: 1
Xft.hintstyle: hintslight
Xft.lcdfilter: lcddefault
Xft.rgba: rgb)
In last 4 comments Mike Fabian has given even more better screenshot showing hinting bytecode which actually affects final output.
http://pravin-s.blogspot.in/2012/12/liberation-20-and-liberatoin-10.html has some more images
Problem is subjectivity of hinting output, each users has different opinion. So just thinking whether we should defer this feature and once Liberation2 output matches with Liberation1 then only we can go with this feature.
Thanks & Regards,
