Werner Lemberg has announced a couple of days ago, on December 30, 2012, that the Groff 1.22.1 software is available for download, featuring various improvements and bug fixes.
Groff, the GNU implementation of Troff, is a document formatting system, which reads mixed plain text and produces formatted output.
