-ikiwiki 1.28 released with these changes:
-
-   * inline: Add ability to sort by page name, based on a patch from
-     Benjamin A'Lee.
-   * Fix a forkbomb in various calls to IPC::Open2, which has a highly
-     braindead interface. Closes: #[389383](http://bugs.debian.org/389383)
-   * Don't rm -rf ikiwiki on distclean, since a) there's no such file
-     and b) those poor Mac OSX users and their case insensative files!
-   * Don't fail syntax check if Text::Typography isn't installed.
-     Closes: #[389406](http://bugs.debian.org/389406)

+ikiwiki 1.31 released with these changes:
+
+   * Patch from Pawel Tecza to cp -a the templates in the Makefile.
+   * Change the rss feed title from the wikiname to the page title, with
+     an exception for the wiki's toplevel index page, which will still use the
+     wikiname as the feed title.
+     Overriding the page title with meta title already overrode the rss feed
+     tittle.
+   * Add an img plugin, based on Christian Mock's img plugin, but stripped
+     down to the bare essentials. Useful for handling large images on websites.
+   * Sanitize possibly problimatic characters out of the polygen grammar names,
+     just in case. Should not be exploitable anyway, since it only tries to run
+     polygen after finding the specified grammar file.
+   * Add missing dependency on the URI perl module.
+   * Add basic spam fighting tool for admins: An admin's prefs page now allows
+     editing a list of banned users.
