+Version 2.0 of ikiwiki is now available.
+
+With the 2.0 release of ikiwiki, some major changes have been made to the
+default configuration:
+
+* The `usedirs` setting is enabled by default. This *will* break all URLs
+ to wikis that did not have `usedirs` turned on before, unless you follow
+ the procedure described at [[switching_to_usedirs]]
+ or edit your setup file to turn` usedirs` off: `usedirs => 0,`
+* [[plugins/OpenID]] logins are now enabled by default, if the
+ [[cpan Net::OpenID::Consumer]] perl module is available. Password logins
+ are also still enabled by default. If you like, you can turn either OpenID
+ or password logins off via the `disable_plugins` setting.
+
