[edit] Detailed Description

Liberation fonts is one of the important font in Fedora distribution.

• Provides metric compatibility with Arial, Times New Roman, and Courier New fonts of Microsoft Windows platform.
• Default fonts in Libre Office.

Issues:

• Existing License of liberation fonts is complex.
• Over the last couple of years we have RFE's to increase coverage of Liberation fonts to support more scripts.
  • "RFE: Add Greek Polytonic support to Liberation fonts" #473842

• We are noticing some tricky Hinting issues. #591554, #591556, #606217 #768067, #768067

Solution:

• Upstream latest release 2.00.0 based on google croscore fonts resolves all these issues.

• It provides support for Greek Polytonic characters. Bug open for this as a RFE.
• Improved hinting.
