 Security reminder: MediaWiki does not require PHP's register_globals
 setting since version 1.2.0. If you have it on, turn it *off* if you can.
 
+== MediaWiki 1.9.1 ==
+
+January 24, 2007
+
+This is a bug-fix update that fixes some installation and upgrade issues
+with the original 1.9.0 release.
+
+* (bug 3000) Fall back to SCRIPT_NAME plus QUERY_STRING when REQUEST_URI is
+  not available, as on IIS with PHP-CGI
+* Security fix for DjVu images. (Only affects servers where .djvu file
+  uploads are enabled and $wgDjvuToXML is set.)
+* (bug 8638) Fix update from 1.4 and earlier
+* (bug 8641) Fix order of updates to ipblocks table for updates from <=1.7
+* (bug 8673) Minor fix for web service API content-type header
+* Fix API revision list on PHP 5.2.1; bad reference assignment
+* Fixed up the AjaxSearch
+* Exclude settings files when generating documentation. That could
+  expose the database user and password to remote users.
+* ar: fix the 'create a new page' on search page when no exact match found
+* Correct tooltip accesskey hint for Opera on the Macintosh
+  (uses Shift-Esc-, not Ctrl-).
+* (bug 8719) Firefox release notes lie! Fix tooltips for Firefox 2 on x11;
+  accesskeys default settings appear to be same as Windows.
