Release Notes: Simplified and improved ntroff expression evaluation.
Release Notes: New logic prevents spurious warnings from .in +N just before .nf. Many more instances of .ta are now automatically handled. Multi-file compilation was broken, and is now repaired.
Release Notes: This release deals with W3C moving a math DTD, improves .Bl/.El handling and updates canned strings in mdoc, accepts \(hy in name sections, handles   (inadvertently omitted from DocBook v4), and adds -V for a version option.
Release Notes: Trailing comments after table rows are now preserved (example: matherr(3)). Support for some previously missing groff extension glyphs was added. Handling of .Bd/.Be in mdoc was improved.
Release Notes: This release handles foojzs pages better, interprets some cases of .rj, recognizes "Feature Test" as a function synopsis ender, handles m, r, and d troff conditionals, processes .ti with positive indent into <blockquote> around the following line, supports all mdoc special-character strings, improved recognition of program listings, and fixed a brown-paper-bag bug in processing of mdoc.
Release Notes: This release fixes a bug in command-synopsis parsing. It now lifts 97% of 11,029 pages in a full Ubuntu Precise Pangolin release.
Release Notes: An improvement was made for lynxprep handling.
Release Notes: This release cleans up glitches revealed by pychecker. It fixes buggy interpretation of the ms .AI macro. It maps the TBL "box" attribute to Docbook frame="border".
Release Notes: The groff \m color extension is now handled. Manpages generated by reStructeredText are dealt with gracefully. Groff-style \F font escapes are coped with better. A partial interpretation of troff \h was added.
Release Notes: eqn markup is now handled if the eqn -TMathml switch produces results. A -w option was added for strict portability checking. All troff glyphs are now mapped - bracket-pile characters, yogh, hooked-o, and underdot were added. You are now warned of sequences that look like glyphs but can't be mapped. Table handling for mdoc pages has been much improved. Tests for requests that can't be turned into structures are stricter.
