--- Comment #4 from Akira TAGOH tagoh@redhat.com --- For f20, no. final change deadline has been gone and GA is coming soon. plus, that change may possibly affects a lot of fonts and it would be risky to do from now.
You can try:
<match target="font"> <test name="fontformat" compare="eq"> <string>CFF</string> </test> <edit name="hintstyle" mode="assign"> <const>hintslight</const> </edit> </match>
instead. that may needs to be tested widely in f21 development timeframe and get a feedback on it because how it looks like is subjective. that said having this kinda recipe per fonts are our policy in Fedora and that would be safe to make any changes. so if you are aware of any other issues, that would be good to file a bug against that problematic font packages unless this kinda changes is needed for a lot of packages.
