Libertinus is a free font family forked from the Linux Libertine and Linux Biolinum fonts that started as an OpenType math companion of the Libertine font family. It has grown to a full fork to address some of the bugs in the fonts.

The family consists of:

Libertinus Serif: forked from Linux Libertine.

Libertinus Sans: forked from Linux Biolinum.

Libertinus Mono: forked from Linux Libertine Mono.

Libertinus Math: an OpenType math font for use in OpenType math-capable applications.

Libertinus typeface is free for personal and commercial use.
