+News for ikiwiki 3.00:
+
+   The 3.0 release of ikiwiki changes several defaults and finishes
+   some transitions. You will need to modify your wikis to work with
+   ikiwiki 3.0. A document explaining the process is available
+   in </usr/share/doc/ikiwiki/html/tips/upgrade\_to\_3.0.html>
+

+     admin preferences into a setup file.
+   * prefix\_directives and aggregate\_internal are now turned on by default.

+   * htmlbalance: Demand-load HTML::TreeBuilder to avoid failing test suite
+     if it is not present.
+   * French translation update from Philippe Batailler. Closes: #[510216](http://bugs.debian.org/510216)
+   * websetup: Avoid a crash when a new array setup item has been added in
+     a new ikiwiki release, and is thus not present in the setup file yet."""]]
