MediaWiki release notes[edit | edit source]

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 1.14.1[edit | edit source]

July 14, 2009

This is a security and bugfix release of the 2009 Q1 branch of MediaWiki. MediaWiki is now using a "continuous integration" development model with quarterly snapshot releases. The latest development code is always kept "ready to run", and in fact runs our own sites on Wikipedia.

Release branches will continue to receive security updates for about a year from first release, but nonessential bugfixes and feature developments will be made on the development trunk and appear in the next quarterly release.

Those wishing to use the latest code instead of a branch release can obtain it from source control: http://www.mediawiki.org/wiki/Download_from_SVN

Note Note: Installation of MediaWiki on SQLite has been temporarily disabled in this release due to the discovery of serious problems with the schema. This was fixed in 1.15.0.

Changes since 1.14.0[edit | edit source]

  • (bug 17737) Fixed russian URLs for Special:BookSources
  • (bug 17713) Using links with only an anchor no longer add an dummy entry in the pagelinks table
  • (bug 17897) Fixed string offset error in <pre> tags
  • (bug 17832) Fixed action=delete returning 'unknownerror' instead of 'permissiondenied' when the user is blocked
  • Fixed performance regression when accessing deleted (archived) files
  • (bug 19693) Fixed cross-site scripting vulnerability in Special:Block

Changes since 1.14.0rc1[edit | edit source]

  • Fixed the performance of the backlinks API module
  • (bug 17420) Send the correct content type from action=raw when the HTML file cache is enabled.
  • (bug 17437) Fixed incorrect link to web-based installer
  • (bug 17527) Fixed missing MySQL-specific options in installer

Configuration changes in 1.14[edit | edit source]

  • $wgExemptFromUserRobotsControl is an array of namespaces to be exempt from the effect of the new __INDEX__/__NOINDEX__ magic words (Default: null, exempt all content namespaces.)
  • $wgForwardSearchUrl has been removed entirely. Documented setting since 1.4 has been $wgSearchForwardUrl.
  • (bug 15080) $wgOverrideSiteFeed has been added. Setting either $wgSiteFeed['rss'] or 'atom' to a URL will override the default Recent Changes feed that appears on all pages.
  • $wgSQLiteDataDirMode has been introduced as the default directory mode for SQLite data directories on creation. Note that this setting is separate from $wgDirectoryMode, which applies to all normal dirs created by MediaWiki.
  • $wgGroupsAddToSelf and $wgGroupsRemoveFromSelf now work more like $wgAddGroups and $wgRemoveGroups, where the user must belong to a specified group in order to add or remove those groups from themselves. Backwards compatibility is maintained.
  • $wgRestrictDisplayTitle controls if the use of the {{DISPLAYTITLE}} magic word is restricted to titles equivalent to the actual page title. This is true per default, but can be set to false to allow any title.
  • $wgSpamRegex may now be an array of multiple regular expressions.
  • $wgAjaxSearch has been removed; use $wgEnableMWSuggest instead.
  • Editing the MediaWiki namespace is now unconditionally restricted to people with the editinterface right, configuring this in $wgNamespaceProtection is not required.
  • $wgAllowExternalImagesFrom may now be an array of multiple strings.
  • Introduced $wgEnableImageWhitelist to toggle the on-wiki external image whitelist on or off.
  • Added $wgRenderHashAppend to append some string to the parser cache and the sitenotice cache keys.
  • $wgRCChangedSizeThreshold is now a positive integer by default,
  • (bug 16006) $wgEnableWriteAPI is now true by default. Authorized can perform write actions using the API.
  • Added $wgRC2UDPInterwikiPrefix which adds an interwiki prefix ($wgLocalInterwiki) onto the page names in the UDP feed.
  • Added $wgAllowUserSkin to let the wiki's owner disable user selectable skins on the wiki. If it's set to true, then the skin used will always be $wgDefaultSkin.
  • Added $wgEnotifUseRealName, which allows UserMailer to send out e-mails based on the user's real name if one is set. Defaults to false (use the username)
  • Removed the 'apiThumbCacheDir' option from $wgForeignFileRepos (only used in ForeignAPIRepo).
  • (bug 44) Image namespace and accompanying talk namespace renamed to File. For backward compatibility purposes, Image still works. External tools may need to be updated.
  • The constants NS_FILE and NS_FILE_TALK can now be used instead of NS_IMAGE and NS_IMAGE_TALK. The old constants are retained as aliases for compatibility, and should still be used in code meant to be compatible with v1.13 or older.
  • MediaWiki can be forced to use private IPs forwarded by a proxy server by using $wgUsePrivateIPs.
  • The 'BeforeWatchlist' hook has been removed due to internal changes in Special:Watchlist. 'SpecialWatchlistQuery' should now be used by extensions to customize the watchlist database query.

Migrated extensions[edit | edit source]

The following extensions are migrated into MediaWiki 1.14:

  • Special:DeletedContributions to show deleted user contributions (was extension DeletedContributions)
  • Special:Log/newusers recording new users (was extension Newuserlog)
  • Special:LinkSearch to search for external links (was extension LinkSearch)
  • RenderHash
  • NoMoveUserPages
  • UniversalEditButton

New features in 1.14[edit | edit source]

  • New URL syntaxes for Special:ListUsers - 'Special:ListUsers/USER' and 'Special:ListUsers/GROUP/USER', in addition to the older syntax 'Special:ListUsers/GROUP' where GROUP is a valid group name.
  • Configurable per-namespace and per-page notices for the edit form, respectively MediaWiki:Editnotice-# where # is the namespace number, and MediaWiki:Editnotice-#-PAGENAME where # is the page's namespace number and PAGENAME is the page name minus the namespace prefix.
  • (bug 8068) New __INDEX__ and __NOINDEX__ magic words allow user control of search engine indexing on a per-article basis.
  • Handheld stylesheet options
  • Added 'DoEditSectionLink' hook as a cleaner unified version of the old 'EditSectionLink' and 'EditSectionLinkForOther' hooks. Note that the 'EditSectionLinkForOther' hook has been removed, but 'EditSectionLink' is run in all cases instead, so extensions using the old hooks should still work if they ran roughly the same code for both hooks (as is almost certain).
  • Signature (~~~~) "cleaning", i.e. template removal, can be disabled with $wgCleanSignatures=false

  • (bug 1250) Users can still use "show preview" and "show changes" even if the wiki is set to read-only mode.

Compatibility[edit | edit source]

MediaWiki 1.14 requires PHP 5 (5.2 recommended). PHP 4 is no longer supported.

PHP 5.0.x fails on 64-bit systems due to serious bugs with array processing:

http://bugs.php.net/bug.php?id=34879

Upgrade affected systems to PHP 5.1 or higher.

MySQL 3.23.x is no longer supported; some older hosts may need to upgrade. At this time we still recommend 4.0, but 4.1/5.0 will work fine in most cases.


Upgrading[edit | edit source]

1.14 has several database changes since 1.13, and will not work without schema updates.

If upgrading from before 1.11, and you are using a wiki as a commons repository, make sure that it is updated as well. Otherwise, errors may arise due to database schema changes.

If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data.

If you are upgrading from MediaWiki 1.4.x or earlier, some major database changes are made, and there is a slightly higher chance that things could break. Don't forget to always back up your database before upgrading!

See the file UPGRADE for more detailed upgrade instructions.

Caveats[edit | edit source]

Some output, particularly involving user-supplied inline HTML, may not produce 100% valid or well-formed XHTML output. Testers are welcome to set $wgMimeType = "application/xhtml+xml"; to test for remaining problem cases, but this is not recommended on live sites. (This must be set for MathML to display properly in Mozilla.)

For notes on 1.13.x and older releases, see HISTORY.

Online documentation[edit | edit source]

Mailing list[edit | edit source]

A MediaWiki-l mailing list has been set up distinct from the Wikipedia wikitech-l list:

mail:mediawiki-l

A low-traffic announcements-only list is also available:

mail:mediawiki-announce

It's highly recommended that you sign up for one of these lists if you're going to run a public MediaWiki, so you can be notified of security fixes.


IRC help[edit | edit source]

There's usually someone online in #mediawiki on irc.freenode.net
