Four years after the last release, version 5.0 of Texinfo, the GNU documentation language, has been released. The primary highlight is a new implementation of makeinfo info in Perl rather than C. Although slower, the new version offers several advantages: cleaner code using a structured representation of the input document, Unicode support, and saner support for multiple output backends. There are over a dozen other improvements including better formatting of URLs, improved cross-manual references, and a program to convert Perl POD documentation to Texinfo.
