From the freshmeat announcement:


The changes in this release are as follows:

This is a fairly major release that includes many bugfixes and feature
enhancements. New features include: multi-file search and replace,
reformatting of bullet lists, gettext() support, restoring the
previous cursor position, better make and grep windows, subroutines
in the syntax definition files (allows reuse of HTML for PHP and
Mason), and new syntax files for Troff, Haskell, Cadance SKILL, REXX,
LUA, and Ruby.
