Change notes from older releases. For current info see RELEASE-NOTES-1.28.
= MediaWiki 1.27 =
== MediaWiki 1.27.0 ==
=== PHP version requirement in 1.27 ===
As of 1.27, MediaWiki now requires PHP 5.5.9 or higher (see Compatibility
section). Additionally, the following PHP extensions are required:
* ctype
* iconv
* json
* mbstring (new requirement in 1.27)
* xml
The following PHP extensions are strongly recommended:
* openssl
=== Configuration changes in 1.27 ===
* $wgAllowMicrodataAttributes and $wgAllowRdfaAttributes were removed,
now always enabled. If you use RDFa on your wiki, you now have to explicitly
set $wgHtml5Version to 'HTML+RDFa 1.0' or 'XHTML+RDFa 1.0'.
* $wgUseLinkNamespaceDBFields was removed.
* Deprecated $wgResourceLoaderMinifierStatementsOnOwnLine and
$wgResourceLoaderMinifierMaxLineLength, because there was little value in
making the behavior configurable. The default values (`false` for the former,
1000 for the latter) are now hard-coded.
* $wgDebugDumpSqlLength was removed (deprecated in 1.24).
* $wgDebugDBTransactions was removed (deprecated in 1.20).
* $wgUseXVO has been removed, as it provides functionality only used by
custom Wikimedia patches against Squid 2.x that probably noone uses in
production anymore. There is now $wgUseKeyHeader that provides similar
functionality but instead of the MediaWiki-specific X-Vary-Options header,
uses the draft Key header standard.
* $wgScriptExtension (and support for '.php5' entry points) was removed. See the
deprecation notice in the release notes for version 1.25 for advice on how to
preserve support for '.php5' entry points via URL rewriting.
* Password handling via the User object has been deprecated and partially
removed, pending the future introduction of AuthManager. In particular:
** expirePassword(), getPasswordExpireDate(), resetPasswordExpiration(), and
getPasswordExpired() have been removed. They were unused outside of core.
** The mPassword, mNewpassword, mNewpassTime, and mPasswordExpires fields are
now private and will be removed in the future.
** The getPassword() and getTemporaryPassword() methods now throw
BadMethodCallException and will be removed in the future.
** The ability to pass 'password' and 'newpassword' to createNew() has been
removed. The only users of it seem to have been using it to set invalid
passwords, and so shouldn't be greatly affected.
** setPassword(), setInternalPassword(), and setNewpassword() have been
deprecated, pending the introduction of AuthManager.
** User::randomPassword() is deprecated in favor of a new method
PasswordFactory::generateRandomPasswordString()
** User::getPasswordFactory() is deprecated, callers should just create a
PasswordFactory themselves.
** A new constructor, User::newSystemUser(), has been added to simplify the
creation of passwordless "system" users for logged actions.
* $wgMaxSquidPurgeTitles was removed.
* $wgAjaxWatch was removed. This is now enabled by default.
* $wgUseInstantCommons now hotlinks Commons images by default instead of
downloading originals and thumbnailing them locally. This allows wikis to save
on CPU and bandwidth while reducing time to first byte for pages, even without
a thumbnail handler. See $wgForeignFileRepos documentation for tweaks.
* (T27397) WebP is enabled by default as an uploadable filetype.
* (T48998) $wgArticlePath must now be either a full url, or start with a "/".
* $wgRateLimitLog was removed; use $wgDebugLogGroups['ratelimit'] instead.
* Deprecated API formats dbg, txt, and yaml have been removed.
* CLDRPluralRule* classes have been replaced with
wikimedia/cldr-plural-rule-parser.
* Removed $wgProfilePerHost, $wgUDPProfilerHost, $wgUDPProfilerPort,
$wgUDPProfilerFormatString, $wgStatsMethod, $wgAggregateStatsID,
$wgStatsFormatString, and $wgProfileCallTree (deprecated since 1.20).
* For proper operation of LocalIdLookup with shared user tables, ensure that
$wgSharedDB and $wgSharedTables are properly set even on the "central" wiki
that all others are sharing from and that $wgLocalDatabases is set to the
full list of sharing wikis on all those wikis.
* Massive overhaul to session handling:
** $wgSessionsInObjectCache is no longer supported and must be true, due to
MediaWiki\Session\SessionManager. $wgSessionHandler is similarly no longer
used.
** ObjectCacheSessionHandler is removed, replaced with
MediaWiki\Session\PhpSessionHandler.
** PHP session handling in general ($_SESSION, session_id(), and so on) is
deprecated. Use MediaWiki\Session\SessionManager instead. A new config
variable, $wgPHPSessionHandling, is available to cause use of $_SESSION to
issue a deprecation warning or to cause most PHP session handling to throw
exceptions.
** Deprecated UserSetCookies hook. Session-handling extensions should generally
be creating a custom subclass of CookieSessionProvider. Other extensions
messing with cookies can no longer count on user data being saved in cookies
versus other methods.
** Deprecated UserLoadFromSession hook, extensions should create a
MediaWiki\Session\SessionProvider.
** The User cannot be loaded from session until after Setup.php completes.
Attempts to do so will be ignored and the User will remain unloaded.
** CSRF tokens may be fetched from the MediaWiki\Session\Session, which uses
the MediaWiki\Session\Token class.
* MediaWiki will now auto-create users as necessary, removing the need for
extensions to do so. An 'autocreateaccount' right is added to allow
auto-creation when 'createaccount' is not granted to all users.
* Deprecated AuthPluginAutoCreate hook in favor of LocalUserCreated.
* Most cookie-handling methods in User are deprecated.
* $wgAllowAsyncCopyUploads and $CopyUploadAsyncTimeout were removed. This was an
experimental feature that has never worked.
* Login and createaccount tokens now vary by timestamp.
* LoginForm::getLoginToken() and LoginForm::getCreateaccountToken()
return a MediaWiki\Session\Token, and tokens must be checked using that
class's methods.
* $wgEnotifUseJobQ was removed and the job queue is always used.
* The functionality of the ApiSandbox extension has been merged into core. The
extension should no longer be used.
* $wgPreloadJavaScriptMwUtil was removed (deprecated in 1.26).
Extensions, skins, gadgets and scripts that use the mediawiki.util module must
express a dependency on it.
* $wgIncludeLegacyJavaScript, deprecated in MediaWiki 1.26, now defaults false.
Extensions, skins, gadgets and scripts that need the mediawiki.legacy.wikibits
module should express a dependency on it.
* Removed configuration option $wgCopyrightIcon (deprecated since 1.18). Use
$wgFooterIcons['copyright']['copyright'] instead.
* If the openssl and mcrypt PHP extensions are both unavailable, secure
session storage (used for login) will raise an exception. This exception may
be bypassed by setting $wgSessionInsecureSecrets = true.
* Massive overhaul to authentication:
** AuthPlugin and AuthPluginUser are deprecated.
** LoginForm and associated templates are deprecated. Extensions which called
static LoginForm methods should be converted into authentication providers.
** The following hooks are deprecated:
*** AbortAutoAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
*** AbortLogin (create a MediaWiki\Auth\PreAuthenticationProvider instead)
*** AbortNewAccount (create a MediaWiki\Auth\PreAuthenticationProvider instead)
*** AddNewAccount (use LocalUserCreated instead)
*** AuthPluginSetup (create a MediaWiki\Auth\PrimaryAuthenticationProvider instead)
*** ChangePasswordForm (use AuthChangeFormFields instead, or security levels)
*** LoginUserMigrated (create a MediaWiki\Auth\PreAuthenticationProvider instead)
*** UserCreateForm (create a MediaWiki\Auth\AuthenticationProvider of some type instead)
*** UserLoginForm (create a MediaWiki\Auth\AuthenticationProvider of some type instead)
** The following hooks are removed:
*** AbortChangePassword
*** LoginPasswordResetMessage
*** PrefsPasswordAudit
** The UserLoginComplete hook will no longer be called for all logins, only for
those via the web UI. Use UserLoggedIn if you need to do something on all
logins.
** $wgRequirePasswordforEmailChange is removed.
=== New features in 1.27 ===
* $wgDataCenterUpdateStickTTL was also added. This decides how long a user
sticks to the primary DC (via cookies) after they make changes to the site.
* Added a new hook, 'UserMailerTransformContent', to transform the contents
of an email. This is similar to the EmailUser hook but applies to all mail
sent via UserMailer.
* Added a new hook, 'UserMailerTransformMessage', to transform the contents
of an emai after MIME encoding.
* Added a new hook, 'UserMailerSplitTo', to control which users have to be
emailed separately (ie. there is a single address in the To: field) so
user-specific changes to the email can be applied safely.
* $wgCdnMaxageLagged was added, which limits the CDN cache TTL
when any load balancer uses a DB that is lagged beyond the 'max lag'
setting in the relevant section of $wgLBFactoryConf.
* User::newSystemUser() may be used to simplify the creation of passwordless
"system" users for logged actions from scripts and extensions.
* Extensions can now return detailed error information via the API when
preventing user actions using 'getUserPermissionsErrors' and similar hooks
by using ApiMessage instances instead of strings for the $result value.
* $wgAPIMaxLagThreshold was added to limit bot changes when databases lag
becomes too high.
* Skins and extensions can now use FlexBox mixins (.flex-display(@display: flex)
and .flex(@grow: 1, @shrink: 1, @width: auto, @order: 1)) in Less to create
cross-browser-compatible FlexBox rules. Users will still need to add fallback
float rules or the like for compatibility with IE9- separately.
* Added MWTimestamp::getTimezoneString() which returns the localized timezone
string, if available. To localize this string, see the comments of
$wgLocaltimezone in includes/DefaultSettings.php.
* Added CentralIdLookup, a service that allows extensions needing a concept of
"central" users to get that without having to know about specific central
authentication extensions.
* $wgMaxUserDBWriteDuration added to limit huge user-generated transactions.
Regular web request transactions that takes longer than this are aborted.
* Added a new hook, 'TitleMoveCompleting', which runs before a page move is
committed.
* $wgCdnReboundPurgeDelay was added to provide secondary delayed purges of URLs
from CDN to mitigate DB replication lag and WAN cache purge lag.
* (T49162) Installer will default to setting CACHE_ACCEL as the main cache type
if it is available.
* It is now possible to patrol file uploads (both for new files and new versions
of existing files). Special:NewFiles has gained an option to filter by patrol
status. This functionality can be disabled using $wgUseFilePatrol.
* MediaWiki\Session infrastructure allows for easier use of session mechanisms
other than the usual cookies.
** SessionMetadata and SessionCheckInfo hooks allow for setting and checking
custom session metadata.
* Added MWGrants and associated configuration settings $wgGrantPermissions and
$wgGrantPermissionGroups to hold configuration for authentication features
such as OAuth that want to allow restricting the user rights a user may make
use of.
** If you're already using the OAuth extension, these new variables are
identical to (and will replace) $wgMWOAuthGrantPermissions and
$wgMWOAuthGrantPermissionGroups.
* Added MWRestrictions as a class to check restrictions on a WebRequest, e.g.
to assert that the request comes from a particular IP range.
* Added bot passwords, a rights-restricted login mechanism for API-using bots.
* Whitelisted the following HTML attributes for all elements in wikitext:
aria-describedby, aria-flowto, aria-label, aria-labelledby, aria-owns.
* Removed "presentation" restriction on the HTML role attribute in wikitext.
All values are now allowed for the role attribute.
* $wgContentHandlers now also supports callbacks to create an instance of the
appropriate ContentHandler subclass.
* Added $wgAuthenticationTokenVersion, which if non-null prevents the
user_token database field from being exposed in cookies. Setting this would
be a good idea, but will log out all current sessions.
* $wgEventRelayerConfig was added, for managing PubSub event relay configuration,
specifically for reliable CDN url purges.
* Requests have unique IDs, equal to the UNIQUE_ID environment variable (when
MediaWiki is behind Apache+mod_unique_id or something similar) or a randomly-
generated 24-character string. This request ID is used to annotate log records
and error messages. It is available client-side via mw.config.get( 'wgRequestId' ).
The request ID supplants exception IDs. Accordingly, MWExceptionHandler::getLogId()
is deprecated.
* (T33313) Add a preference for watching uploads by default, also applies
to API-based upload tools.
* $wgJpegPixelFormat was added to override chroma subsampling for JPEG image
thumbnails created via ImageMagick. Defaults to 'yuv420', providing bandwidth
savings versus the previous behavior on many files.
* MediaWiki\Auth infrastructure (called "AuthManager") allows for more flexible
configuration of multiple authentication pieces that was possible with
AuthPlugin. For example, it's now easy to plug in second-factor
authentication, or add additional checks to the login process, or to support
multiple login methods at once, or to support non-password-based login methods.
** Providers are configured via the global setting $wgAuthManagerConfig.
** A global, $wgDisableAuthManager, is temporarily available to disable
AuthManager until extensions are ready to support it.
** New hook, AuthChangeFormFields, to adjust the form fields on
AuthManager-related special pages.
** New hook, AuthManagerLoginAuthenticateAudit, for additional logging of
AuthManager-related authentication requests.
** New hook, ChangeAuthenticationDataAudit, for additional logging of
AuthManager-related authentication data changes.
** New hook, SecuritySensitiveOperationStatus, to work with the new mechanism
for requiring a recent login before taking security-sensitive operations
like changing a password.
** Two new globals, $wgChangeCredentialsBlacklist and $wgRemoveCredentialsBlacklist
can be used to prevent the web UI and the API changing certain authentication data.
* The file upload dialog (available if you install WikiEditor or VisualEditor)
can now be configured using $wgUploadDialog.

under HHVM (T116347).
* (T54077) The APIEditBeforeSave hook will once again give only the content of
the section being edited, rather than the whole revision. This reverts the
change made in MediaWiki 1.22.
=== Action API changes in 1.27 ===
* Added list=allrevisions.
* generator=recentchanges now has the option to generate revids.
* ApiPageSet::setRedirectMergePolicy() was added. This allows generator

merely need to change the username and password used after setting up a bot
password.
* action=upload no longer understands statuskey, asyncdownload or leavemessage.
* Several changes when $wgDisableAuthManager is false:
** action=login is deprecated for uses other than bot passwords.

=== Compatibility ===
MediaWiki 1.27 requires PHP 5.5.9 or later. There is experimental support for
HHVM 3.6.5 or later.
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 ===
1.27 has several database changes since 1.26, 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 1.26.x and older releases, see HISTORY.
= MediaWiki 1.26 =
== MediaWiki 1.26.2 ==
This is a maintenance release of the MediaWiki 1.26 branch.
=== Changes since 1.26.1 ===
* (T121892) Fix fatal error on some Special pages, introduced in 1.26.1.
== MediaWiki 1.26.1 ==
This is a maintenance release of the MediaWiki 1.26 branch.
=== Changes since 1.26.0 ===
* (T117899) SECURITY: $wgArticlePath can no longer be set to relative paths
that do not begin with a slash. This enabled trivial XSS attacks.
Configuration values such as "http://my.wiki.com/wiki/$1" are fine, as are
"/wiki/$1". A value such as "$1" or "wiki/$1" is not and will now throw an
error.
* (T119309) SECURITY: Use hash_compare() for edit token comparison
* (T118032) SECURITY: Don't allow cURL to interpret POST parameters starting
with '@' as file uploads
* (T115522) SECURITY: Passwords generated by User::randomPassword() can no
longer be shorter than $wgMinimalPasswordLength
* (T97897) SECURITY: Improve IP parsing and trimming. Previous behavior could
result in improper blocks being issued
* (T109724) SECURITY: Special:MyPage, Special:MyTalk, Special:MyContributions
and related pages no longer use HTTP redirects and are now redirected by
MediaWiki
* Fixed ConfigException in ExpandTemplates due to AlwaysUseTidy.
* Fixed stray literal \n in Special:Search.
* Fix issue that breaks HHVM Repo Authorative mode.
* (T120267) Work around APCu memory corruption bug
== MediaWiki 1.26.0 ==
=== Configuration changes in 1.26 ===
* $wgPasswordResetRoutes['email'] = true by default.
* $wgEnableParserCache was deprecated, set $wgParserCacheType to CACHE_NONE
instead if you want to disable the parser cache.
* New-style continuation is now the default for API action=continue. Clients may
use the 'rawcontinue' parameter to receive raw query-continue data, but the
new style is encouraged as it's harder to implement incorrectly.
* Deprecated API formats dump and wddx have been completely removed.
* (T7645) The "Signature" button on the edit toolbar is now hidden by default
in non-talk namespaces. A new configuration variable,
$wgExtraSignatureNamespaces, controls in which subject (non-talk) namespaces
the "Signature" button on the edit toolbar will be displayed.
* $wgResourceLoaderUseESI was deprecated and removed. This was an experimental
feature that was never enabled by default.
* $wgResourceLoaderExperimentalAsyncLoading was deprecated and removed.
This experimental feature was never enabled by default and is obsolete as of
MediaWiki 1.26, in where ResourceLoader became fully asynchronous.
* $wgMasterWaitTimeout was removed (deprecated in 1.24).
* Fields in ParserOptions are now private. Use the accessors instead.
* Custom LESS functions (defined via $wgResourceLoaderLESSFunctions or
in extension.json) have been removed, after being deprecated in 1.24.
* $wgAlwaysUseTidy has been removed.
* ResetSessionID hook has been removed. Nothing seems to use it.
* Certain AuthPlugin methods are deprecated in favor of new hooks:
** AuthPlugin::initUser() is replaced by LocalUserCreated.
** AuthPlugin::updateUser() is replaced by UserLoggedIn.
** AuthPlugin::updateExternalDB() is replaced by the existing UserSaveSettings.
** AuthPlugin::updateExternalDBGroups() is replaced by UserGroupsChanged.
** AuthPluginUser::isHidden() is replaced by UserIsHidden.
** AuthPluginUser::isLocked() is replaced by UserIsLocked.
* The UserRights hook is deprecated in favor of the new UserGroupsChanged hook.
* AuthPlugin::initUser() and AuthPlugin::updateUser() should no longer replace
the passed User object.
* $wgBlockAllowsUTEdit is now set to true by default. This allows
blocked users to edit their talk pages unless explicitly disabled
when they are being blocked.
=== New features in 1.26 ===
* (T51506) Now action=info gives estimates of actual watchers for a page.
See $wgRCMaxAge, $wgWatchersMaxAge and $wgUnwatchedPageSecret
to learn how to configure if needed.
* Change tags can now be hidden in the interface by disabling the associated
"tag-<id>" interface message.
* ':' (colon) is now invalid in usernames for new accounts. Existing accounts
are not affected.
* Added a new hook, 'LogException', to log exceptions in nonstandard ways.
* Revive the 'SpecialSearchResultsAppend' hook which occurs after the list of
search results are rendered. The initial use case is to append a "give us
feedback" link beneath the search results.
* Added a new hook, 'RejectParserCacheValue', which allows extensions to
reject an otherwise-successful parser cache lookup. The intent is to allow
extensions to manage the eviction of archaic HTML output from the cache.
* (T68699) The expiration of the UserID and Token login cookies
($wgExtendedLoginCookieExpiration) can be configured independently of the
expiration of all other cookies ($wgCookieExpiration).
* (T50519) Support for generating JPEG/PNG thumbnails from WebP images added
if ImageMagick is used as image scaler ($wgUseImageMagick = true). Uploading
of WebP images still disabled by default. Add $wgFileExtensions[] =
'webp'; to LocalSettings.php to enable uploading of WebP images.
* Added new hooks 'EnhancedChangesListModifyLineData' &
'EnhancedChangesListModifyBlockLineData', to modify the data used to build
lines in enhanced recentchanges and watchlist.
* Caches that need purging ability now use the WANObjectCache interface.
This corresponds to a new $wgMainWANCache setting, which defaults to using
the $wgMainCacheType settings.
* Callers needing fast light-weight data stores use $wgMainStash to select
the store type from $wgObjectCaches. The default is the local database.
* Interface message overrides in the MediaWiki namespace will now be cached in
memcached and APC (if available), rather than memcached and local files.
* Added a new hook, 'RandomPageQuery', to allow modification of the query used
by Special:Random to select random pages.
* $wgTransactionalTimeLimit was added, which controls the request time limit
for potentially slow POST requests that need to be as atomic as possible.
* ResourceLoader now loads all scripts asynchronously. The top-queue and
startup modules are no longer synchronously loaded.
* 'mediawiki.ui.button' styles are no longer unconditionally loaded on every
page. During the deprecation period, the styles will only be loaded on pages
which contain 'mw-ui-button' in their HTML. Starting in 1.28, the styles will
only be loaded if explicitly required.
* If search returns zero results and current search engine has a "did you mean"
suggestion, results for suggestion will be shown. Can be disabled by setting
$wgSearchRunSuggestedQuery to false.
* Added several JavaScript libraries for uploading files to MediaWiki
from the client-side. See documentation for mw.Upload and its
subclasses for more information.
* Added OOUI dialogs and layout for file upload interfaces. See
documentation for mw.Upload.Dialog, mw.Upload.BookletLayout and its
subclasses for more information.
=== extension.json changes in 1.26 ===
* (T99344) The extension.json schema is now versioned. All extensions
and skins should set a "manifest_version" property corresponding to
the schema version they were written for. The only supported version
currently is "1".
* (T102523) The error message if a non-array attribute is set was improved.
* (T107646) Configuration settings can now specify how they should be merged,
which is necessary for arrays using integer keys.
* (T110389) Adding namespaces through extension.json now actually works
* $wgNamespaceProtection can now be set in extension.json.
* $wgCapitalLinkOverrides can now be set in extension.json.
* (T97186) Extensions using a custom prefix for their configuration settings
can now set a "_prefix" key to override the default of "wg".
* (T99084) Extensions can now specify what MediaWiki core versions they
depend upon.
* (T105236) The extension.json schema now validates custom classes in
the "ResourceModules" property properly.
=== External library changes in 1.26 ===
==== Upgraded external libraries ====
* Updated es5-shim from v4.0.0 to v4.1.5.

==== Removed and replaced external libraries ====
* Replaced leafo/lessphp v0.5.0 with oyejorge/less.php v1.7.0.9.
=== Bug fixes in 1.26 ===
* (T53283) load.php sometimes sends 304 response without full headers
* (T65198) Talk page tabs now have a "rel=discussion" attribute
* (T98841) {{msgnw:}} now preserves comments even when subst: is not used.
* (T104142) $wgEmergencyContact and $wgPasswordSender now use their default
value if set to an empty string.
=== Action API changes in 1.26 ===
* New-style continuation is now the default for action=continue. Clients may
use the 'rawcontinue' parameter to receive raw query-continue data, but the
new style is encouraged as it's harder to implement incorrectly.
* Deprecated API formats dump and wddx have been completely removed.
* API action=query&list=tags: The displayname can now be boolean false if the
tag is meant to be hidden from user interfaces.
* action=import no longer allows both the namespace= and rootpage= parameters
to be set. If they are both set, the value of rootpage= will be ignored.
* prop=revision output in enum mode is now sorted by timestamp rather than
revision ID. This usually won't make any difference.
* (T102645) Namespace list from meta=siteinfo&siprop=namespaces is now an array
with formatversion=2.
* Various other output from meta=siteinfo will now always be arrays instead of
sometimes being numerically-indexed objects with formatversion=2.
* When errors about users being blocked are returned, they now include
information about the relevant block.
* (T99926) list=random has higher limits, in line with other API modules.
* list=random's rnredirect parameter is deprecated in favor of a new
rnfilterredir parameter that also allows for listing both redirects and
non-redirects.
* list=random now supports continuation.
* API responses to GET requests may now include ETag and Last-Modified headers,
and will honor corresponding If-None-Match and If-Modified-Since on such
requests.
=== Action API internal changes in 1.26 ===
* New metadata item ApiResult::META_KVP_MERGE to allow for merging the KVP key
into the value when the value is an assoc.
* API action modules may now provide values for the RFC 7232 ETag and
Last-Modified headers. The API will check these against If-None-Match and
If-Modified-Since request headers on GET requests and avoid executing the
module when appropriate.
=== Languages updated in 1.26 ===
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 Phabricator reports.
* Languages added:
** ase (American sign language), thanks to translator Icemandeaf
** dty (डोटेली/Doteli), thanks to translators जनक राज भट्ट, बिप्लब आनन्द,
मेश सिंह बोहरा, and राम प्रसाद जोशी
** luz (لئری دوٙمینی / Southern Luri)
** olo (Livvinкarjala / Livvi-Karelian), thanks to translators Denö, Hiloin Natoi,
Ilja.mos, and Mashoi7
=== Other changes in 1.26 ===
* ChangeTags::tagDescription() will return false if the interface message
for the tag is disabled.
* Added PageHistoryPager::doBatchLookups hook.
* Added $wikiId parameter to FormatAutocomments hook.
* Added ParserCacheSaveComplete to ParserCache
* supportsDirectEditing and supportsDirectApiEditing methods added to
ContentHandler, to provide a way for ApiEditPage and EditPage to check
if direct editing of content is allowed. These methods return false,
by default for the ContentHandler base class and true for TextContentHandler
and it's derivative classes (everything in core). For Content types that
do not support direct editing, an alternative mechanism should be provided
for editing, such as action overrides or specific api modules.
* mediaWiki.confirmCloseWindow now returns an object of functions, instead of
one function. The callback can't be called directly any more. The callback
function is replaced with confirmCloseWindow.release().
* BREAKING CHANGE: Added an optional ResouceLoaderContext parameter to
ResourceLoaderModule::getDependencies(). Extension classes that override that
method should be updated. If they aren't updated, PHP Strict standards
warnings will appear when E_STRICT error reporting is enabled. Note: in the
near future, this parameter will probably become non-optional.
* Removed maintenance script deleteImageMemcached.php.
* MWFunction::newObj() was removed (deprecated in 1.25).
ObjectFactory::getObjectFromSpec() should be used instead.
* The parser will no longer randomize the string it uses to mark the place of
items that were stripped during parsing. It will use a fixed string instead.
This causes the parser to re-use the regular expressions it uses to search
and replace markers rather than generate novel expressions on each parse.
Re-using regular expressions will improve performance on HHVM and the
forthcoming PHP 7. The interfaces changes accompanying this change are:
- Parser::getRandomString() and Parser::uniqPrefix() have been deprecated.
- The $uniq_prefix argument for Parser::extractTagsAndParams() and the
$prefix argument for StripState::_construct() are deprecated and their
value is ignored.
* wfSuppressWarnings() and wfRestoreWarnings() were split into a separate library,
mediawiki/at-ease, and are now deprecated. Callers should use
MediaWiki\suppressWarnings() and MediaWiki\restoreWarnings() directly.
* The Block class constructor now takes an associative array of parameters
instead of many optional positional arguments. Calling the constructor the old
way will issue a deprecation warning.
* The jquery.mwExtension module was deprecated.
* $wgSpecialPageGroups was removed (deprecated in 1.21).
* SpecialPageFactory::setGroup was removed (deprecated in 1.21).
* SpecialPageFactory::getGroup was removed (deprecated in 1.21).
* DatabaseBase::ignoreErrors() is now protected.
* BREAKING CHANGE: mediawiki.legacy.ajax has been removed, following
a lengthy deprecation period.
* The ScopedPHPTimeout class was removed.
* Removed maintenance script fixSlaveDesync.php.
* Watchlist tokens, SpecialResetTokens, and User::getTokenFromOption()
are deprecated. Applications using those can work via the OAuth
extension instead. New tokens types should not be added.
* DatabaseBase::errorCount() was removed (unused).
* $wgDeferredUpdateList was removed.
* DeferredUpdates::addHTMLCacheUpdate() was removed.

* (T102522) Using an extension.json or skin.json file which has
a "manifest_version" property for 1.26 compatability will no longer
trigger warnings.
* (T86156) Running updateSearchIndex.php will not throw an error as
page_restrictions has been added to the locked table list.
* Special:Version would throw notices if using SVN due to an incorrectly
named variable. Add an additional check that an index is defined.
== MediaWiki 1.25.1 ==
This is a bug fix release of the MediaWiki 1.25 branch.
=== Changes since 1.25 ===
* (T100351) Fix syntax errors in extension.json of ConfirmEdit extension
== MediaWiki 1.25.0 ==
=== 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'.
