Disadvantage

Not bytecode hinting instructions.

We tried to change Liberation 1.07.4 with Liberation 2.00.1 in Fedora 19 but due to regression about hinting, we revoked this change.

Over the period many users suggested for upgrade. We had discussion on fedora devel lists and also in fedora i18n meeting about same.

Planning to package both liberation version in Fedora and lets users decide the one which they want to use.

Plan: Liberation 1.07.4 -> Renamed to LiberationOne Liberation 2.00.1 -> Packaged as Liberation fonts.

User can install both at the same time, proper font config alias will be provided.

Benefit to Fedora

Liberation 2.00.1 has wider character coverage. Users can get both Liberation fonts version and they can decide version they want to use.

This is not drastic new change, only providing options to user.

Scope

Proposal owners:

- Presently liberation upstream has both version in single repo (in different branch). Need to split this repo into different one for LiberationOne and Liberation.
- Changing Font names for liberation 1.07.4 to Liberation One.
- Packaging Liberation One to Fedora and providing proper aliases.
- Updating Liberation fonts package to version 2.00.1
