For notes on 1.44.x and older releases, see HISTORY. === Configuration changes for system administrators in 1.45 === * $wgPHPSessionHandling is now deprecated, and the default value has been changed to 'warn'. Any extension that uses PHP session handling ($_SESSION, session_start(), etc.) will cause warnings to be emitted. Migration instructions: https://www.mediawiki.org/wiki/Manual:SessionManager_and_AuthManager/Updating_tips#SessionManager Known affected extensions: https://codesearch.wmcloud.org/things/?q=\%24_SESSION|\ssession_\w%2B\s*\(&files=\.php%24 Integration with PHP session handling will be removed in the future, making PHP session handling and MediaWiki session handling independent. Using PHP session handling may cause conflicts with the cookies used by MediaWiki. To silence the warnings and restore previous behavior, use `$wgPHPSessionHandling = 'enable';`. This configuration setting will be removed in a future release. To silence the warnings and disable integration with PHP session handling, use `define( 'MW_NO_SESSION_HANDLER', 1 );`. This constant will always be defined in a future release. * $wgSitemapNamespacesPriorities is deprecated and ignored. * $wgCSPUploadEntryPoint to control if img_auth.php & thumb.php send CSP headers * $wgEnableProtectionIndicators is now enabled by default. If your community already uses protection indicators you might want to disable this setting, or customize them with site CSS. ==== New configuration ==== * (T389281) $wgUseLeximorph - Defaults to false. When enabled, core parser functions for grammar, plural, gender, formality, and bidi use the Leximorph library’s modular handlers instead of the legacy Language methods. When disabled, the legacy methods are used. ==== Changed configuration ==== * (T402094) $wgReauthenticateTime now defaults to 3600 seconds instead of 60 seconds (1 minute to 1 hour) to improve the user experience ==== Removed configuration ==== * (T13555, T371756) $wgParserEnableLegacyHeadingDOM was removed. The skin option 'supportsMwHeading' was likewise removed. New heading markup is now always enabled, on all skins. More information: https://www.mediawiki.org/wiki/Heading_HTML_changes * (T387856) $wgEnotifImpersonal and $wgEnotifMaxRecips, deprecated in 1.44, are no longer honoured. * (T394054) $wgParserEnableLegacyMediaDOM and $wgUseContentMediaStyles were removed. New media markup is now always enabled. More information: https://www.mediawiki.org/wiki/Parsoid/Parser_Unification/Media_structure/FAQ * (T299947) $wgPageLinksSchemaMigrationStage has been removed. * (T405087) $wgDBDefaultGroup has been removed without deprecation. Use ILBFactory::setDefaultGroupName() instead. * (T306325) $wgEnableSearchContributorsByIP has been removed. * (T389893) 'multiPrimaryMode' has been removed from SqlBagOStuff config. * (T299951) $wgCategoryLinksSchemaMigrationStage, a temporary setting which controls the database schema migration for the categorylinks table, has been removed. === New user-facing features in 1.45 === * (T219543) [[Special:SpecialPages]], the index of special pages, now has a search box that filters the list. * (T118132) After using [[Special:MergeHistory]] to merge page histories, [[Special:Log]] will show entries for both the source and the destination page. Previously, the merge was only logged for the source page. * (T384578) Attempting to create a redirect to an invalid target, such as Special:UserLogout, will now result in a warning. * (T280531) Partial action blocks is now enabled by default. This feature allows administrators to block users from performing certain actions (such as moving pages) without blocking them from editing pages. * (T328254) A new parser function has been added, {{#contentmodel}}, which returns the localized name of the contentmodel of the current page. This is primarily meant for use in system messages. * (T382958) [[Special:MergeHistory]] is now significantly more flexible about what it can merge. It can now merge sections taken from the middle of the history of the source (rather than only the start) and insert revisions anywhere in the history of the destination page (rather than only the start) === New developer features in 1.45 === * The new built-in notifications framework is now stable for use by extensions. https://www.mediawiki.org/wiki/Manual:Notifications * The Status and StatusValue classes can now be documented as generic classes with a type parameter for their value. These annotations allow IDEs and static analysis tools to better understand the types in code such as: /** @return StatusValue<Foo> */ function doStuff(): StatusValue { ... } doStuff()->getValue()->bar(); * The UserLinkRendererUserPostRenderLink hook was added. * The LocalUserOptionsStoreSave hook was added. * The User::getConfirmationToken(), User::getConfirmationTokenUrl() and User::getInvalidationTokenUrl() methods were added. * The User::getTokenUrl() method was made public. * The SpecialLogResolveLogType hook was added. * Domain events modeling changes to pages are now stable for use by extensions. See https://www.mediawiki.org/wiki/Manual:Domain_events/Hierarchy#Page_Events * CentralIdLookup::getScope() has been added, for easier namespacing of central IDs. * SessionManager::getJwtData() has been added, to standardize JWT format for session providers which use a JWT. * The JwtCodec service has been added, for encoding/decoding JWTs. * The LeximorphFactory service was added. * (T402154) MessagePostProcessText and MessagePostProcessHtml hooks were added. * (T396889) In the past, messages that have to exist for technical reason but shouldn't be translated, were added to the usual en.json and qqq.json files, and then configured as 'ignored' in translatewiki. From now on, such messages should be added to the en.json and qqq.json file under nontranslatable/. * (T315128) The UserCanChangeEmail hook was added. * (T295568) The jqueryMsg parser now supports self-closing HTML tags (<br>, <wbr> and <hr>). === External library changes in 1.45 === ==== New external libraries ==== * Added lcobucci/jwt 4.1.5. * Added symfony/polyfill-php8.5 v1.33.0. * Added wikimedia/codex ("Codex-PHP") v0.7.1. ==== Changed external libraries ==== * Updated codex, codex-design-tokens and codex-icons from v1.23.0 to v2.3.2. * Updated composer/semver from 3.4.3 to 3.4.4. * Renamed cssjanus/cssjanus to wikimedia/cssjanus. * Updated guzzlehttp/guzzle from 7.9.3 to 7.10.0. * Updated mck89/peast from v1.17.0 to 1.17.2. * Updated oojs/oojs-ui from v0.51.7 to v0.53.0. * Updated psr/container from 1.1.2 to 2.0.2. * Updated symfony/polyfill-php82 from 1.32.0 to 1.33.0. * Updated symfony/polyfill-php83 from 1.32.0 to 1.33.0. * Updated symfony/polyfill-php84 from 1.32.0 to 1.33.0. * Updated symfony/yaml from 5.4.45 to 6.4.25. * Updated wikimedia/cldr-plural-rule-parser from 2.0.0 to 3.0.0. * Updated wikimedia/css-sanitizer from 5.5.0 to 6.1.0 * Updated wikimedia/json-codec from 3.0.3 to 4.0.0. * Updated wikimedia/less.php from 5.2.1 to 5.2.2. * Updated wikimedia/parsoid from 0.21.1 to 0.22.0. * Updated wikimedia/php-session-serializer from 3.0.1 to 3.0.2. * Updated wikimedia/remex-html from 4.1.2 to 5.1.0. * Updated wikimedia/request-timeout from 2.0.2 to 3.0.0. * Updated wikimedia/shellbox from 4.2.0 to 4.3.0. * Updated wikimedia/timestamp from 4.2.0 to 5.0.0. * Updated wikimedia/xmp-reader from 0.9.4 to 0.10.2. ===== Changed development-only external libraries ===== * Updated composer/spdx-licenses from 1.5.8 to 1.5.9. * Updated doctrine/dbal from 3.9.4 to 3.10.0. * Updated doctrine/sql-formatter from 1.3.0 to 1.5.2. * Updated eslint-config-wikimedia from 0.29.1 to 0.31.0. * Updated mediawiki/mediawiki-codesniffer from 46.0.0 to 48.0.0. * Updated mediawiki/mediawiki-phan-config from 0.15.0 to 0.17.0. === Action API changes in 1.45 === * (T396049) The list of domains supported by the upload-by-URL feature is now exposed via meta=siteinfo. * (T399897) The `parsoid` parameter to `action=parse` has been deprecated.
