Detailed Description
Lohit Odia and Telugu fonts are available from 2004. Over the years number of redundant and incorrect open type rules got added into this to cope up with different layout engine available with Pango, Qt and ICU. We started using Harfbuzz-NG unified shaper in Fedora from Fedora 19. Its time to clean-up Odia and Telugu open type tables and make them effective and efficient by following all the standards around font technology. Under Lohit2 project this is happening with Fedora 22 release cycle.
Benefit to Fedora
Lohit Odia and Telugu are default fonts for Odia and Telugu language respectively in Fedora. Making these fonts as per latest open type specification and following recent language related guidelines further help to prove Fedora leadership in language technologies. Optimization in font happen w.r.t. Glyphs and open type tables.

Upgrade/compatibility impact
Upgrade will be smooth. No Manual configuration required. This upgrade will be backward compatible.
How To Test
1. Update Fedora with latest fonts.
2. Use test file available with newly package for testing.
3. Use utrrs utrrs-testing.rhcloud.com/language/or and utrrs-testing.rhcloud.com/language/te for testing.

User Experience
- Lohit Odia and Telugu are doing good job as a systems default fonts. But there is chance that over the year few things from Language perspective might have changed. Also there is chance that few rare words are not working fine.
- With Lohit2 project thorough testing will happen by going through all the language standard and user will experience better font.
