Change notes from older releases. For current info see RELEASE-NOTES-1.26.
== MediaWiki 1.25 ==
=== Configuration changes in 1.25 ===
* $wgPageShowWatchingUsers was removed.
* $wgLocalVirtualHosts has been added to replace $wgConf->localVHosts.
* $wgAntiLockFlags was removed.
* $wgJavaScriptTestConfig was removed.
* Edit tokens returned from User::getEditToken may change on every call. Token
validity must be checked by passing the user-supplied token to
User::matchEditToken rather than by testing for equality with a
newly-generated token.
* (T74951) The UserGetLanguageObject hook may be passed any IContextSource
for its $context parameter. Formerly it was documented as receiving a
RequestContext specifically.
* Profiling was restructured and $wgProfiler now requires an 'output' parameter.
See StartProfiler.sample for details.
* $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that
might be a flash policy directive configurable.
* ApiOpenSearch now supports XML output. The OpenSearchXml extension should no
longer be used. If extracts and page images are desired, the TextExtracts and
PageImages extensions are required.
* $wgOpenSearchTemplate is deprecated in favor of $wgOpenSearchTemplates.
* Edits are now prepared via AJAX as users type edit summaries. This behavior
can be disabled via $wgAjaxEditStash.
* (T46740) The temporary option $wgIncludejQueryMigrate was removed, along
with the jQuery Migrate library, as indicated when this option was provided in
MediaWiki 1.24.
* ProfilerStandard and ProfilerSimpleTrace were removed. Make sure that any
StartProfiler.php config is updated to reflect this. Xhprof is available
for zend/hhvm. Also, for hhvm, one can consider using its xenon profiler.
* Default value of $wgSVGConverters['rsvg'] now uses the 'rsvg-convert' binary
rather than 'rsvg'.
* Default value of $wgSVGConverters['ImageMagick'] now uses transparent
background with white fallback color, rather than just white background.
* MediaWikiBagOStuff class removed, make sure any object cache config
uses SqlBagOStuff instead.
* The 'daemonized' flag must be set to true in $wgJobTypeConf for any redis
job queues. This means that mediawiki/services/jobrunner service has to
be installed and running for any such queues to work.
* $wgAutopromoteOnce no longer supports the 'view' event. For keeping some
compatibility, any 'view' event triggers will still trigger on 'edit'.
* $wgExtensionDirectory was added for when your extensions directory is somewhere
other than $IP/extensions (as $wgStyleDirectory does with the skins directory).
=== New features in 1.25 ===
* (T64861) Updated plural rules to CLDR 26. Includes incompatible changes
for plural forms in Russian, Prussian, Tagalog, Manx and several languages
that fall back to Russian.
* (T60139) ResourceLoaderFileModule now supports language fallback
for 'languageScripts'.
* Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
parser output for a content object before links update.
* (T37785) Enhanced recent changes and extended watchlist are now default.
Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
and https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions.
* (T69341) SVG images will no longer be base64-encoded when being embedded
in CSS. This results in slight size increase before gzip compression (due to
percent-encoding), but up to 20% decrease after it.
* Update jStorage to v0.4.12.
* MediaWiki now natively supports page status indicators: icons (or short text
snippets) usually displayed in the top-right corner of the page. They have
been in use on Wikipedia for a long time, implemented using templates and CSS
absolute positioning.
- Basic wikitext syntax: [[File:Foo.svg|20px]]
- Usage instructions: https://www.mediawiki.org/wiki/Help:Page_status_indicators
- Adjusting custom skins to support indicators:
https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
* Edit tokens may now be time-limited: passing a maximum age to
User::matchEditToken will reject any older tokens.
* The debug logging internals have been overhauled, and are now using the
PSR-3 interfaces.
* Update CSSJanus to v1.1.1.
* Update lessphp to v0.5.0.
* Added a hook, "ApiOpenSearchSuggest", to allow extensions to provide extracts
and images for ApiOpenSearch output. The semantics are identical to the
"OpenSearchXml" hook provided by the OpenSearchXml extension.
* PrefixSearchBackend hook now has an $offset parameter. Combined with $limit,
this allows for pagination of prefix results. Extensions using this hook
should implement supporting behavior. Not doing so can result in undefined
behavior from API clients trying to continue through prefix results.
* Update jQuery from v1.11.1 to v1.11.3.
* External libraries installed via composer will now be displayed
on Special:Version in their own section. Extensions or skins that are
installed via composer will not be shown in this section as it is assumed
they will add the proper credits to the skins or extensions section. They
can also be accessed through the API via the new siprop=libraries to
ApiQuerySiteInfo.
* Update QUnit from v1.14.0 to v1.16.0.
* Update Moment.js from v2.8.3 to v2.8.4.
* Special:Tags now allows for manipulating the list of user-modifiable change
tags.
* Added 'managetags' user right and 'ChangeTagCanCreate', 'ChangeTagCanDelete',
and 'ChangeTagCanCreate' hooks to allow for managing user-modifiable change
tags.
* Added 'ChangeTagsListActive' hook, to separate the concepts of "defined" and
"active" formerly conflated by the 'ListDefinedTags' hook.
* Added TemplateParser class that provides a server-side interface to cachable
dynamically-compiled Mustache templates (currently uses lightncandy library).
* Clickable anchors for each section heading in the content are now generated
and appear in the gutter on hovering over the heading.
* Added 'CategoryViewer::doCategoryQuery' and 'CategoryViewer::generateLink' hooks
to allow extensions to override how links to pages are rendered within NS_CATEGORY
* (T19665) Special:WantedPages only lists page which having at least one red link
pointing to it.
* New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
used for conditional registration of API modules.
* New hook 'EnhancedChangesList::getLogText' to alter, remove or add to the
links of a group of changes in EnhancedChangesList.
* A full interface for StatsD metric reporting has been added to the context
interface, reachable via IContextSource::getStats().
* Move the jQuery Client library from being mastered in MediaWiki as v0.1.0 to a
proper, published library, which is now tagged as v1.0.0.
* A new message (defaulting to blank), 'editnotice-notext', can be shown to users
when they are editing if no edit notices apply to the page being edited.
* (T94536) You can now make the sitenotice appear to logged-in users only by
editing MediaWiki:Anonnotice and replacing its content with "". Setting it to
"-" (default) will continue disable it and fallback to MediaWiki:Sitenotice.
* Modifying the tagging of a revision or log entry is now available via
Special:EditTags, generally accessed via the revision-deletion-like interface
on history pages and Special:Log is likely to be more useful.
* Added 'applychangetags' and 'changetags' user rights.
* (T35235) LogFormatter subclasses are now responsible for formatting the
parameters for API log event output. Extensions should implement the new
getParametersForApi() method in their log formatters.
==== External libraries ====
* MediaWiki now requires certain external libraries to be installed. In the past
these were bundled inside the Git repository of MediaWiki core, but now they
need to be installed separately. For users using the tarball, this will be taken
care of and no action will be required. Users using Git will either need to use
composer to fetch dependencies or use the mediawiki/vendor repository which includes
all dependencies for MediaWiki core and ones used in Wikimedia deployment. Detailed
instructions can be found at:
https://www.mediawiki.org/wiki/Download_from_Git#Fetch_external_libraries
* The following libraries are now required:
** psr/log
This library provides the interfaces set by the PSR-3 standard (http://www.php-fig.org/psr/psr-3/)
which are used by MediaWiki internally via the
MediaWiki\Logger\LoggerFactory class.
See the structured logging RfC (https://www.mediawiki.org/wiki/Requests_for_comment/Structured_logging)
for more background information.
** cssjanus/cssjanus
This library was formerly bundled with MediaWiki core and has been removed.
It automatically flips CSS for RTL support.
** leafo/lessphp
This library was formerly bundled with MediaWiki core and has been removed.
It compiles LESS files into CSS.
** wikimedia/cdb
This library was formerly a part of MediaWiki core, and has been moved into a separate library.
It provides CDB functions which are used in the Interwiki and Localization caches.
More information about the library can be found at https://www.mediawiki.org/wiki/CDB.
** liuggio/statsd-php-client
This library provides a StatsD client API for logging application metrics to a remote server.
=== Bug fixes in 1.25 ===
* (T73003) No additional code will be generated to try to load CSS-embedded
SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
* (T69021) On Special:BookSources, corrected validation of ISBNs (both
10- and 13-digit forms) containing "X".
* Page moving was refactored into a MovePage class. As part of that:
** The AbortMove hook was removed.
** MovePageIsValidMove is for extensions to specify whether a page
cannot be moved for technical reasons, and should not be overridden.
** MovePageCheckPermissions is for checking whether the given user is
allowed to make the move.
** Title::moveNoAuth() was deprecated. Use the MovePage class instead.
** Title::moveTo() was deprecated. Use the MovePage class instead.
** Title::isValidMoveOperation() broken down into MovePage::isValidMove()
and MovePage::checkPermissions().
* (T18530) Multiple autocomments are now formatted in an edit summary.
* (T70361) Autocomments containing "/*" are parsed correctly.
* The Special:WhatLinksHere page linked from 'Number of redirects to this page'
on action=info about a file page does not list file links anymore.
* (T78637) Search bar is not autofocused unless it is empty so that proper scrolling using arrow keys is possible.
* (T50853) Database::makeList() modified to handle 'NULL' separately when building IN clause
* (T85192) Captcha position modified in Usercreate template. As a result:
** extrafields parameter added to Usercreate.php to insert additional data
** 'extend' method added to QuickTemplate to append additional values to any field of data array
* (T86974) Several Title methods now load from the database when necessary
(instead of returning incorrect results) even when the page ID is known.
* (T74070) Duplicate search for archived files on file upload now omits the extension.
This requires the fa_sha1 field being populated.
* Removed rel="archives" from the "View history" link, as it did not pass
HTML validation.
* $wgUseTidy is now set when parserTests are run with the tidy option to match
output on wiki.
* (T37472) update.php will purge ResourceLoader cache unless --nopurge is passed to it.
* (T72109) mediawiki.language should respect $wgTranslateNumerals in convertNumber().
=== Action API changes in 1.25 ===
* (T67403) XML tag highlighting is now only performed for formats
"xmlfm" and "wddxfm".
* action=paraminfo supports generalized submodules (modules=query+value),
querymodules and formatmodules are deprecated
* action=paraminfo no longer outputs descriptions and other help text by
default. If needed, it may be requested using the new 'helpformat' parameter.
* action=help has been completely rewritten, and outputs help in HTML
rather than plain text.
* Hitting api.php without specifying an action now displays only the help for
the main module, with links to submodule help.
* API help is no longer displayed on errors.
* 'uselang' is now a recognized API parameter; "uselang=user" may be used to
explicitly select the language from the current user's preferences, and
"uselang=content" may be used to select the wiki's content language.
* Default output format for the API is now jsonfm.
* Simplified continuation will return a "batchcomplete" property in the result
when a batch of pages is complete.
* Pretty-printed HTML output now has nicer formatting and (if available)
better syntax highlighting.
* Deprecated list=deletedrevs in favor of newly-added prop=deletedrevisions and
list=alldeletedrevisions.
* prop=revisions will gracefully continue when given too many revids or titles,
rather than just ignoring the extras.
* prop=revisions will no longer die if rvcontentformat doesn't match a
revision's content model; it will instead warn and omit the content.
* If the user has the 'deletedhistory' right, action=query's revids parameter
will now recognize deleted revids.
* prop=revisions may be used as a generator, generating revids.
* (T68776) format=json results will no longer be corrupted when
$wgMangleFlashPolicy is in effect. format=php results will cleanly return an
error instead of returning invalid serialized data.
* Generators may now return data for the generated pages when used with
action=query.
* Query page data for generator=search and generator=prefixsearch will now
include an "index" field, which may be used by the client for sorting the
search results.
* ApiOpenSearch now supports XML output.
* ApiOpenSearch will now output descriptions and URLs as array indexes 2 and 3
in JSON format.
* (T76051) list=tags will now continue correctly.
* (T76052) list=tags can now indicate whether a tag is defined.
* (T75522) list=prefixsearch now supports continuation
* (T78737) action=expandtemplates can now return page properties.
* (T78690) list=allimages now accepts multiple pipe-separated values
for the 'aimime' parameter.
* prop=info with inprop=protections will now return applicable protection types
with the 'restrictiontypes' key.
* (T85417) When resolving redirects, ApiPageSet will now add the targets of
interwiki redirects to the list of interwiki titles.
* (T85417) When outputting the list of redirect titles, a 'tointerwiki'
property (like the existing 'tofragment' property) will be set.
* Added action=managetags to allow for managing the list of
user-modifiable change tags. Actually modifying the tagging of a revision or
log entry is not implemented yet.
* list=tags has additional properties to indicate 'active' status and tag
sources.
* siprop=libraries was added to ApiQuerySiteInfo to list installed external libraries.
* (T88010) Added action=checktoken, to test a CSRF token's validity.
* (T88010) Added intestactions to prop=info, to allow querying of
Title::userCan() via the API.
* Default type param for query list=watchlist and list=recentchanges has
been changed from all types (e.g. including 'external') to 'edit|new|log'.
* Added formatversion to format=json. Still "experimental" as further changes
to the output formatting might still be made.
* (T73020) Log event details are now always under a 'params' subkey for
list=logevents, and a 'logparams' subkey for list=watchlist and
list=recentchanges.
* Log event details are changing formatting:
* block events now report flags as an array rather than as a comma-separated
list.
* patrol events now report the 'auto' flag as a boolean (absent/empty string
for BC formats) rather than as an integer.
* rights events now report the old and new group lists as arrays rather than
as comma-separated lists.
* merge events use new-style formatting.
* delete/event and delete/revision events use new-style formatting.
* The root node and various other nodes will now always be an object in formats
such as json that distinguish between arrays and objects.
* Except for action=opensearch where the spec requires an array.
=== Action API internal changes in 1.25 ===
* ApiHelp has been rewritten to support i18n and paginated HTML output.
Most existing modules should continue working without changes, but should do
the following:
* Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
* Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
to replace getParamDescription(). If necessary, the settings array returned
by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
message.
* Implement getExamplesMessages() to replace getExamples().
* Modules with submodules (like action=query) must have their submodules
override ApiBase::getParent() to return the correct parent object.
* The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
and will have no effect for modules using i18n messages. Use
'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
* Api formatters will no longer be asked to display the help screen on errors.
* ApiMain::getCredits() was removed. The credits are available in the
'api-credits' i18n message.
* ApiFormatBase has been changed to support i18n and syntax highlighting via
extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
has been removed.
* ApiFormatBase now always buffers. Output is done when
ApiFormatBase::closePrinter is called.
* Much of the logic in ApiQueryRevisions has been split into ApiQueryRevisionsBase.
* The 'revids' parameter supplied by ApiPageSet will now count deleted
revisions as "good" if the user has the 'deletedhistory' right. New methods
ApiPageSet::getLiveRevisionIDs() and ApiPageSet::getDeletedRevisionIDs() are
provided to access just the live or just the deleted revids.
* Added ApiPageSet::setGeneratorData() and ApiPageSet::populateGeneratorData()
to allow generators to include data in the action=query result.
* New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
used for conditional registration of API modules.
* Added ApiBase::lacksSameOriginSecurity() to allow modules to easily check if
the current request was sent with the 'callback' parameter (or any future
method that breaks the same-origin policy).
* Profiling methods in ApiBase are deprecated and no longer need to be called.
* ApiResult was greatly overhauled. See inline documentation for details.
* ApiResult will automatically convert objects to strings or arrays (depending
on whether a __toString() method exists on the object), and will refuse to
add unsupported value types.
* An informal interface, ApiSerializable, exists to override the default
object conversion.
* ApiResult/ApiFormatBase "raw mode" is deprecated.
* ApiFormatXml now assumes defaults and so on instead of throwing errors when
metadata isn't set.
* (T35235) LogFormatter subclasses are now responsible for formatting log event
parameters for the API.
* Many modules have changed result data formats. While this shouldn't affect
clients not using the experimental formatversion=2, code using
ApiResult::getResultData() without the transformations for backwards
compatibility may need updating, as will code that wasn't following the old
conventions for API boolean output.
* The following methods have been deprecated and may be removed in a future
release:
* ApiBase::getDescription
* ApiBase::getParamDescription
* ApiBase::getExamples
* ApiBase::makeHelpMsg
* ApiBase::makeHelpArrayToString
* ApiBase::makeHelpMsgParameters
* ApiBase::getModuleProfileName
* ApiBase::profileIn
* ApiBase::profileOut
* ApiBase::safeProfileOut
* ApiBase::getProfileTime
* ApiBase::profileDBIn
* ApiBase::profileDBOut
* ApiBase::getProfileDBTime
* ApiBase::getResultData
* ApiFormatBase::setUnescapeAmps
* ApiFormatBase::getWantsHelp
* ApiFormatBase::setHelp
* ApiFormatBase::formatHTML
* ApiFormatBase::setBufferResult
* ApiFormatBase::getDescription
* ApiFormatBase::getNeedsRawData
* ApiMain::setHelp
* ApiMain::reallyMakeHelpMsg
* ApiMain::makeHelpMsgHeader
* ApiResult::setRawMode
* ApiResult::getIsRawMode
* ApiResult::getData
* ApiResult::setElement
* ApiResult::setContent
* ApiResult::setIndexedTagName_recursive
* ApiResult::setIndexedTagName_internal
* ApiResult::setParsedLimit
* ApiResult::beginContinuation
* ApiResult::setContinueParam
* ApiResult::setGeneratorContinueParam
* ApiResult::endContinuation
* ApiResult::size
* ApiResult::convertStatusToArray
* ApiQueryImageInfo::getPropertyDescriptions
* ApiQueryLogEvents::addLogParams
* The following classes have been deprecated and may be removed in a future
release:
* ApiQueryDeletedrevs
=== Languages updated in 1.25 ===
MediaWiki supports over 350 languages. Many localisations are updated
regularly. Below only new and removed languages are listed, as well as
changes to languages because of Bugzilla reports.
* Languages added:
** awa (अवधी / Awadhi), thanks to translator 1AnuraagPandey;
** bgn (بلوچی رخشانی / Western Balochi), thanks to translators
Baloch Afghanistan, Ibrahim khashrowdi and Rachitrali;
** ses (Koyraboro Senni), thanks to translator Songhay.
* (T66440) Kazakh (kk) wikis should no longer forcefully reset the user's
interface language to kk where unexpected.
* The Chinese conversion table was substantially updated to fix a lot of
bugs and ensure better reading experience for different variants.
=== Other changes in 1.25 ===
* (T45591) Links to MediaWiki.org translatable help were added to indicators,
mostly in special pages. Local custom target titles can be placed in the
relevant '(namespace-X|action name|special page name)-helppage' system
message. Extensions can use the addHelpLink() function to do the same.
* The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
migration guide for creators and users of custom skins that relied on it.
* Javascript variables 'wgFileCanRotate' and 'wgFileExtensions' now only
available on Special:Upload.
* (T58257) Set site logo from mediawiki.skinning.interface module instead of
inline styles in the HTML.
* Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
* Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
* Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
* Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
* Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
* Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
since 1.20)
* Removed 'async' parameter from the mw.Api#getCategories() method. (deprecated
since 1.20)
* Removed 'jquery.json' module. (deprecated since 1.24)
Use the 'json' module and global JSON object instead.
* Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
Also, the former will now throw an MWException if called with one or more
arguments.
* Removed hitcounters and associated code.
* The "temp" zone of the upload respository is now considered private. If it
already exists (such as under the images/ directory), please make sure that
the directory is not web readable (e.g. via a .htaccess file).
* BREAKING CHANGE: In the XML dump format used by Special:Export and
dumpBackup.php, the and tags now apprear before the
tag, instead of after the and tags.
The new schema version is 0.10, the new schema URI is:
https://www.mediawiki.org/xml/export-0.10.xsd
* MWFunction::call() and MWFunction::callArray() were removed, having being
deprecated in 1.22.
* Deprecated the getInternalLinkAttributes, getInternalLinkAttributesObj,
and getInternalLinkAttributes methods in Linker, and removed
getExternalLinkAttributes method, which was deprecated in MediaWiki 1.18.
* Removed Sites class, which was deprecated in 1.21 and replaced by SiteSQLStore.
* Added wgRelevantArticleId to the client-side config, for use on special pages.
* Deprecated the TitleIsCssOrJsPage hook. Superseded by the
ContentHandlerDefaultModelFor hook since MediaWiki 1.21.
* Deprecated the TitleIsWikitextPage hook. Superseded by the
ContentHandlerDefaultModelFor hook since MediaWiki 1.21.
* Changed parsing of variables in schema (.sql) files:
** The substituted values are no longer parsed. (Formerly, several passes
were made for each variable, so depending on the order in which variables
were defined, variables might have been found inside encoded values. This
is no longer the case.)
** Variables are no longer string encoded when the /*$var*/ syntax is used.
If string encoding is necessary, use the '{$var}' syntax instead.
** Variable names must only consist of one or more of the characters
"A-Za-z0-9_".
** In source text of the form '{$A}'{$B}' or `{$A}`{$B}`, where variable A
does not exist yet variable B does, the latter may not be replaced.
However, this difference is unlikely to arise in practice.
* (T67278) RFC, PMID, and ISBN "magic links" must be surrounded by non-word
characters on both sides.
* The FormatAutocomments hook will now receive $pre and $post as booleans,
rather than as strings that must be prepended or appended to $comment.
* (T30950, T31025) RFC, PMID, and ISBN "magic links" can no longer contain
newlines; but they can contain and other non-newline whitespace.
* The 'mediawiki.action.edit' ResourceLoader module no longer generates the edit
toolbar, which has been moved to a separate 'mediawiki.toolbar' module. If you
relied on this behavior, update your scripts' dependencies.
* HTMLForm's 'vform' display style has been separated to a subclass. Therefore:
* HTMLForm::isVForm() is now deprecated.
* You can no longer do this:
$form = new HTMLForm( … );
$form->setDisplayFormat( 'vform' ); // throws exception
Instead, do this:
$form = HTMLForm::factory( 'vform', … );
* Deprecated Revision methods getRawUser(), getRawUserText() and getRawComment().
* BREAKING CHANGE: mediawiki.user.generateRandomSessionId:
The alphabet of the prior string returned was A-Za-z0-9 and now it is 0-9A-F
* (T87504) Avoid serving SVG background-images in CSS for Opera 12, which
renders them incorrectly when combined with border-radius or background-size.
* Removed maintenance script dumpSisterSites.php.
* DatabaseBase class constructors must be called using the array argument style.
Ideally, DatabaseBase:factory() should be used instead in most cases.
* Deprecated ParserOutput::addSecondaryDataUpdate and ParserOutput::getSecondaryDataUpdates.
This is a hard deprecation, with getSecondaryDataUpdates returning an empty array and
addSecondaryDataUpdate throwing an exception. These functions will be removed in 1.26,
since they interfere with caching of ParserOutput objects.
* Introduced new hook 'SecondaryDataUpdates' that allows extensions to inject custom updates.
* Introduced new hook 'OpportunisticLinksUpdate' that allows extensions to perform
updates when a page is re-rendered.
* EditPage::attemptSave has been modified not to call handleStatus itself and
instead just returns the Status object. Extension calling it should be aware of
this.
* Removed class DBObject. (unused since 1.10)
* wfDiff() is deprecated.
* The -m (maximum replication lag) option of refreshLinks.php was removed.
It had no effect since MediaWiki 1.18 and should be removed from any cron
jobs or similar scripts you may have set up.
* (T85864) The following messages no longer support raw html: redirectto,
thisisdeleted, viewdeleted, editlink, retrievedfrom, version-poweredby-others,
retrievedfrom, thisisdeleted, viewsourcelink, lastmodifiedat, laggedslavemode,
protect-summary-cascade
* All BloomCache related code has been removed. This was largely experimental.
* $wgResourceModuleSkinStyles no longer supports per-module local or remote paths. They
can only be set for the entire skin.
* Removed global function swap(). (deprecated since 1.24)
* Deprecated the ".php5" file extension entry points and the $wgScriptExtension
configuration variable. Refer to the ".php" files instead. If you want
".php5" URLs to continue to work, set up redirects. In Apache, this can be
done by enabling mod_rewrite and adding the following rules to your
configuration:
RewriteEngine On
RewriteBase /
RewriteRule ^(.*)\.php5 $1.php [R=301,L]
* The global importScriptURI and importStylesheetURI functions, as well as the
loadedScripts object, from wikibits.js (deprecated since 1.17) now emit
warnings through mw.log.warn when accessed.
== Compatibility ==
MediaWiki 1.25 requires PHP 5.3.3 or later. There is experimental support for
HHVM 3.3.0.
MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
support for them is somewhat less mature. There is experimental support for
Oracle and Microsoft SQL Server.
The supported versions are:
* MySQL 5.0.3 or later
* PostgreSQL 8.3 or later
* SQLite 3.3.7 or later
* Oracle 9.0.1 or later
* Microsoft SQL Server 2005 (9.00.1399)
== Upgrading ==
1.25 has several database changes since 1.24, and will not work without schema
updates. Note that due to changes to some very large tables like the revision
table, the schema update may take quite long (minutes on a medium sized site,
many hours on a large site).
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, you should upgrade to
1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
with MediaWiki 1.21.
Don't forget to always back up your database before upgrading!
See the file UPGRADE for more detailed upgrade instructions.
For notes on 1.24.x and older releases, see HISTORY.
== MediaWiki 1.24 ==
=== Configuration changes in 1.24 ===
* MediaWiki will no longer run if register_globals is enabled. It has been
deprecated for 5 years now, and was removed in PHP 5.4. For more information
about why, see .
* MediaWiki now requires PHP's iconv extension. openSUSE users may need to
install the php5-iconv package. Users of other systems may need to add
extension=iconv.so to php.ini or recompile PHP without --without-iconv.
* MediaWiki will no longer function if magic quotes are enabled. It has
been deprecated for 5 years now, and was removed in PHP 5.4.
* The server's canonical hostname is available as $wgServerName, which is
exposed in both mw.config and ApiQuerySiteInfo.
* Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch,
for using the old schema of the page_props table, in case the respective
schema update was not applied.
* $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
* $wgMasterWaitTimeout has been deprecated.
* $wgDBClusterTimeout has been removed.
* $wgProxyKey has been removed. It is no longer used by MediaWiki core.
Ensure $wgSecretKey is set in LocalSettings.php.
* $wgExtraInterlanguageLinkPrefixes is a new configuration variable that
contains an array of interwiki prefixes that should be treated as language
prefixes (i.e. turned into interlanguage links when $wgInterwikiMagic is set
to true).
* $wgParserTestRemote has been removed.
* $wgCountTotalSearchHits has been removed. If you're concerned about efficiency
of search, you should use something like CirrusSearch instead of built in
search.
* Users in the 'sysop' group have access to Special:MergeHistory by default.
* $wgFileStore was removed after having been deprecated in 1.17. Alternative
configurations are $wgDeletedDirectory and $wgHashedUploadDirectory.
* The deprecated $wgUseCommaCount variable has been removed.
* $wgEnableSorbs and $wgSorbsUrl have been removed.
* The UserCryptPassword and UserComparePassword hooks are no longer called.
Any extensions using them must be updated to use the Password Hashing API.
* $wgCompiledFiles has been removed.
* $wgSortSpecialPages was removed, the listing on Special:SpecialPages is
now always sorted.
* $wgSpecialPages may now use callback functions as an alternative to plain class names.
This allows more control over constructor parameters.
* $wgHTCPMulticastAddress, $wgHTCPMulticastRouting and $wgHTCPPort were removed.
* $wgRC2UDPAddress, $wgRC2UDPInterwikiPrefix, $wgRC2UDPOmitBots, $wgRC2UDPPort
and $wgRC2UDPPrefix have been removed.
* The default password type for MediaWiki has been changed from MD5 to PBKDF2.
Password hashes will automatically be updated as users log in. If necessary, the
old MD5 hashing can be restored by changing $wgPasswordDefault to 'B'. In addition,
there is a maintenance script wrapOldPassword.php that can wrap all passwords in
PBKDF2 (or the hashing algorithm of your choice) if you don't want to wait for your
users to log in.
* $wgImportSources can now either be a regular array, or an associative map
specifying subprojects on the interwiki map of the target wiki, or a mix of
the two. Existing configurations will still work.
* Users must be able to edit through a page's protection to be able to delete it.
* The default thumb size ($wgDefaultUserOptions['thumbsize']) is now 300px, up from
180px. If you have altered the number of entries in $wgThumbLimits for your wiki, you
may need to adjust your default user settings to compensate for the index change.
* $wgDeferredUpdateList is now deprecated, you should use DeferredUpdates::addUpdate()
instead.
* $wgCanonicalLanguageLinks has been removed. Per Google recommendations, we
will not send a rel=canonical pointing to a variant-neutral page, however
we will send rel=alternate.
* $wgResourceLoaderLESSFunctions has been deprecated and will be removed in the future.
* $wgGoToEdit has been removed. Use the SpecialSearchNogomatch hook for similar
functionality.
=== New features in 1.24 ===
* Added new hook WatchlistEditorBeforeFormRender, allowing subscribers to
manipulate the list of pages and/or preload lots of data at once.
* Added new argument &$link in hook WatchlistEditorBuildRemoveLine, allowing the
link to the title to be changed.
* Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
WhatLinksHere entries.
* Added a new hook, "ContentGetParserOutput", to customize parser output for
a given content object.
* Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
* HTMLForm's HTMLTextField now supports the 'url' type.
* HTMLForm fields may now be dynamically hidden based on the values of other
fields in the form.
* HTMLForm now supports multiple copies of an input field or set of input
fields, e.g. the form may request "one or more usernames" without having to
have the user enter delimited list of names into a text field.
* Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
the sidebar just before its display.
* (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
jquery.cookie so that getting/setting a cookie is syntactically and
functionally similar to using the WebRequest::getCookie() and
WebResponse::setcookie() methods.
* (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
$wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
This option is turned off by default, and will be removed in MediaWiki 1.25.
* (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
* Changes to content typography (fonts, etc.). See
https://www.mediawiki.org/wiki/Typography_refresh for further information.
* WikitextContent will now render redirects with the expected "redirect"
header, rather than as an ordered list. Code calling Article::viewRedirect
can probably be changed to no longer special-case redirects.
* Header font set to a serif font stack. See
https://www.mediawiki.org/wiki/Typography_refresh for further information.
* (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
is only for page views, since this hook doesn't affect UserLogin, OAuth,
CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
overall design of the system.
* (bug 17367) It is now possible to add pages to your watchlist from
Special:UnwatchedPages without reloading the special page.
* New methods setVolatile and isVolatile are added to PPFrame, so that
extensions such as Cite.php can mark that their output is volatile and
shouldn't be cached.
* (bug 52817) Advanced search options are now saved on the search page itself,
rather than in a dedicated pane in the preferences panel.
* (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
the Vector skin has gained a label that should make it more discoverable.
* MWCryptHKDF added for fast, cryptographically secure random number generation
that won't deplete openssl's entropy pool.
* ResourceLoader: File modules can now provide a skip function that uses an
inline feature test to bypass loading of the module.
* (bug 20210) Special pages may now provide autocompletion of their subpage
names in search suggestions. Right now the only useful implementation is in
Special:Log, but more are to come.
* Special:MostLinkedTemplates is no longer limited to transclusions from the
Template namespace.
* Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
This works the same as 'remoteExtPath' but is relative to the skins/ folder
instead of the extensions/ folder.
* Added the json2.js polyfill for the ES5 JSON.stringify and JSON.parse methods.
Exposed as module "json" with a skip function to optimise loading.
* Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition
to 'name', to allow for the name to be localizable. 'name' should still be
specified for backwards-compatibility and to define the path Special:Version
uses to find extension license information.
* Browser tests are now included to verify basic wiki functionality in developer
environments. For details on running tests, see tests/browser/README.mediawiki.
* Upgrade jStorage to v0.4.10.
* {{!}} is now a magic word that produces the | character. This removes the need
for Template:! for purposes such as passing pipes inside of parameters.
* (bug 20790) The block log snippet on Special:Contributions and while
editing user and user talk pages now works for IP range blocks.
* (bug 9360) Added ability to change the page language for MediaWiki pages using
Special:PageLanguage. All pages are set to wiki language by default.
The feature needs to be enabled with $wgPageLanguageUseDB=true and
permission needs to be set for 'pagelang'.
* Upgrade Moment.js to v2.8.3.
* (bug 67042) Added support for the HTML5
