We now have custom fonts (also known as the local_fonts module) functionality! This allows you to create custom fonts which can be exported/imported via the configuration api. We also have various bug fixes included in the beta release.
Upgrade to this if you want PHP 7 compatibility, D7 7.50 compatibility, and new features
backwards compatible with PHP 5.3, 5.4, 5.5, 5.6
