The Bitstream Vera collection of fonts was released a few days ago (get them from the GNOME fonts page). From the Bitstream press release:
In a move to fill the last remaining gap in font display capabilities for open source software, the GNOME Foundation has reached an agreement with Bitstream (Nasdaq: BITS) to release fonts under an open source license. A total of ten serif, sans serif and monospaced fonts will be released under a special open source license, after they have been adapted to meet the requirements for technical use. The set of ten fonts will bring advanced font capabilities to all developers and users of free and open source software.
To celebrate the release, I’ve knocked-up a commemorate stylesheet for this site. I’ve called it “Duckworth”. You can switch to it on the style switching section of the customise page.
