-   * autoindex: New plugin that generates missing index pages.
-     (Sponsored by The TOVA Company.)
-   * Escape HTML is rss and atom feeds instead of respectively using CDATA and
-     treating it as XHTML. This avoids problems with escaping the end of the
-     CDATA when the htmlscrubber is not used, and it avoids problems with atom
-     XHTML using named entity references that are not in the atom DTD. (Simon McVittie)
-   * Add test for old versions of git that don't support --cleanup=verbatim,
-     and munge empty commit messages."""]]
