-ikiwiki 2.51 released with [[!toggle text="these changes"]]
-[[!toggleable text="""
-   * Improve toplevel parentlink to link directly to index.html when usedirs is
-     disabled.
-   * map: Add a "show" parameter. "show=title" can be used to display page
-     titles, rather than the default page name. Based on a patch from
-     Jaldhar H. Vyas, Closes: #[484510](http://bugs.debian.org/484510)
-   * hnb: New plugin, contributed by Axel Beckert.
-   * meta: Store "description" in pagestate for use by other plugins.
-   * map: Support show=description.
-   * textile: The Text::Textile perl module has some regexps that fail if
-     input is flagged as utf-8, but contains invalid characters such as 0x92.
-     To prevent it from crashing, re-encode the content before calling it,
-     which will ensure that it's really utf-8.
-   * Version the suggests of xapian-omega to a version known to be new enough
-     to work with ikiwiki. Reportedly, version 0.9.9 is too old to work.
-     Closes: #[486592](http://bugs.debian.org/486592)
-   * creole: New plugin from Bernd Zeimetz. Closes: #[486930](http://bugs.debian.org/486930)
-   * aggregate: Add template parameter.
-   * Add support for the universal edit button <http://universaleditbutton.org/>
-     (To get this on all pages of an exiting wiki, rebuild the wiki.)
-   * txt: New plugin, contributed by Gabriel McManus.
-   * smiley: Generate links relative to the destpage. (Fixes a reversion from
-     2.41.)
-   * toc: Revert change in 2.45 that made it run at sanitize time. That broke
-     use of toc in a sidebar.
-   * Call format hooks when generating page previews, thus fixing toc display
-     there, as well as fixing inlins to again display in page previews, since
-     it's started using format hooks. This also allows several other things,
-     like embed, that use format hooks, to work during page preview time.
-   * Format hooks should not rely on getting an entire html document, as they
-     will only get the body during page preview.
-   * toggle: Deal with preview mode when adding javascript."""]]

+   * 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."""]]
