MediaWiki release notes

Version 1.1.0, 2003-12-08

This is the new production release. Any following 1.1.x releases are expected to contain only bug fixes; developments of new features will go towards a 1.2.0 release. New features in 1.1:

  • User-editable interface messages: http://meta.wikipedia.org/wiki/MediaWiki_namespace
  • XML-wrapped page source export with optional history: http://meta.wikipedia.org/wiki/XML_import_and_export (There is not yet an import function!)
  • "Magic words" Fixes and tweaks:
  • linkscc table caches link data for rendering; faster rebuildlinks.php
  • Numerous bugs in Cologne Blue skin fixed
  • Login gives warning about missing cookies
  • Block log, protection log added; deletion log now includes undeletions
  • Deletion & upload logs now escape comment text properly
  • Problems with <nowiki> segments in section titles etc mitigated
  • Contributions offset and minor edit bugs fixed
  • Whatlinkshere now sorted alphabetically
  • Various exciting new profiling options.
  • Debug log is off by default.
  • Various small bugs fixed. Internal changes:
  • wfQuery has had a second parameter inserted, DB_READ or DB_WRITE. This value is not actually used so far.
  • Partial code for categories and Smarty template-based skins is in the tree but disabled.
  • Parts of Article.php have been moved to EditPage.php and ImagePage.php. New translations:
  • fi - Finnish
  • ia - Interlingua
  • no - Norwegian
  • sk - Slovak
  • ta - Tamil

Database changes

"linkscc" table added. If upgrading manually (rather than with update.php), run maintenance/archives/patch-linkscc.sql to create the table. Older releases were dated snapshots from the old 'stable' branch:


  • Image deletion fixed.
  • Deletion of image old revisions now restricted to sysops (this is an irreversible action and not well logged)
  • Fixed maintenance scripts broken by last release's security fix
  • Many errors in rebuildlinks script fixed.


  • SECURITY FIX: stricter checking of include path
  • Fixed user contributions next/prev bug
  • Login cookies now have the database name prefixed to allow wikis to coexist in the same domain. This will invalidate any old saved password cookies.
  • Update cache timestamp when talk pages are created
  • Saving the login form in Mozilla no longer blanks password in prefs.
  • Check existence of source page before performing a move.
  • Detect invalid titles in Special:Allpages
  • Q-encode headers on outgoing inter-user e-mail
  • Updates to some translations.
  • Added table of contents border/bg to Cologne Blue, Nostalgia skins
  • Protected pages no longer appear unprotected when visited via redirect
  • Swapped old Wikipedia logo for the MediaWiki sunflower logo
  • install.php, update.php print warning on old PHP versions, added compatibility functions that might or might not help No database changes since 20031107; upgrading should be clean.


  • Fixed various bugs!
  • Some speed improvements from tweaks to the table indexes
  • Limited support for memcached (see below)
  • New translations (see below)
  • Interwiki link data now kept in database for flexibility
  • Friendlier read-only source view if asked to edit a page when the db is locked or the page is protected.
  • Normal IP blocks auto-expire after 24 hours
  • Optional support for blocking usernames
  • Uploads disabled by default (see below)

Security note

Uploads are now disabled by default. If you've set up a secure configuration you can reenable uploads by putting: $wgDisableUploads = false; into LocalSettings.php. Earlier versions of MediaWiki included a bug that potentially allows logged- in users to delete arbitrary files in directories writable by the web server user by manually feeding false form data; this is now fixed. As a reminder, disable PHP script execution in the upload directory! You may also wish to serve HTML pages as plaintext to prevent cookie- stealing JavaScript attacks. Example Apache config fragment:

<Directory "/Library/MediaWiki/web/upload">
     # Ignore .htaccess files
     AllowOverride None
     # Serve HTML as plaintext
     AddType text/plain .html .htm .shtml
     # Don't run arbitrary PHP code.
     php_admin_flag engine off
     # If you've other scripting languages, disable them too.

Database updates

If you're using update.php, the necessary database changes should be made automatically. To manually upgrade your database from the 2003-08-29 release, run the following SQL scripts from the maintenance subdirectory: archives/patch-ipblocks.sql archives/patch-interwiki.sql archives/patch-indexes.sql interwiki.sql To copy in the Wikipedia language-prefix interwikis as well, add: wikipedia-interwiki.sql


New interface localization files are included for:

  • fy - Frisian
  • ro - Romanian
  • sl - Slovene
  • sq - Albanian
  • sr - Serbian


Memcached is a distributed cache system. See http://www.danga.com/memcached/ MediaWiki can optionally use memcached to store some data between calls to reduce load on the database. Currently this is limited to user and talk page notification data, interwiki prefix/URL matches, and the UTF-8 conversion tables. MediaWiki includes version 1.0.10 of the (GPL'd) PHP memcached client by Ryan Gilfether; if memcached is disabled it acts as a dummy object with minimal overhead. To use memcached you'll need PHP installed with sockets support (this is not in the default configure options). See docs/memcached for some more details. Additionally, you can store login session data in memcached instead of the local filesystem, which can help to enable load-balancing by letting login sessions transparently work on multiple front-end web servers. (The primary other issue is with uploads, which requires some care in handling.) To enable this, set $wgSessionsInMemcached = true; and set $wgCookieDomain appropriately if exposing multiple hostnames. This system is new and may be volatile; login sessions will fail dramatically if memcached is unavailable when this option is turned on.

Online documentation

Documentation for both end-users and site administrators is currently being built up on Meta-Wikipedia, and is covered under the GNU Free Documentation License: http://meta.wikipedia.org/wiki/MediaWiki_User%27s_Guide

Mailing list

A MediaWiki-l mailing list has been set up distinct from the Wikipedia wikitech-l list: http://mail.wikipedia.org/mailman/listinfo/mediawiki-l

UseModWiki import script

A stripped-down UseModWiki import script is available in the maintenance subdirectory. It is incomplete and requires a lot of manual clean-up, but does function for the brave and pure of heart.

Test suite removed

The unmaintained Java-based test suite has been removed from the tarball release. If you really want it you can check it out from CVS.


First release under MediaWiki name.
