RELEASE-NOTES-1.25

   1 Security reminder: If you have PHP's register_globals option set, you must
   2 turn it off. MediaWiki will not work with it enabled.

   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.25 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.25 ===
  12 * $wgPageShowWatchingUsers was removed.
  13 * $wgLocalVirtualHosts has been added to replace $wgConf->localVHosts.
  14 * $wgAntiLockFlags was removed.
  15 * $wgJavaScriptTestConfig was removed.
  16 * Edit tokens returned from User::getEditToken may change on every call. Token
  17   validity must be checked by passing the user-supplied token to
  18   User::matchEditToken rather than by testing for equality with a
  19   newly-generated token.
  20 * (T74951) The UserGetLanguageObject hook may be passed any IContextSource
  21   for its $context parameter. Formerly it was documented as receiving a
  22   RequestContext specifically.
  23 * Profiling was restructured and $wgProfiler now requires an 'output' parameter.
  24   See StartProfiler.sample for details.
  25 * $wgMangleFlashPolicy was added to make MediaWiki's mangling of anything that
  26   might be a flash policy directive configurable.
  27 * ApiOpenSearch now supports XML output. The OpenSearchXml extension should no
  28   longer be used. If extracts and page images are desired, the TextExtracts and
  29   PageImages extensions are required.
  30 * $wgOpenSearchTemplate is deprecated in favor of $wgOpenSearchTemplates.
  31 * Edits are now prepared via AJAX as users type edit summaries. This behavior
  32   can be disabled via $wgAjaxEditStash.
  33 * (T46740) The temporary option $wgIncludejQueryMigrate was removed, along
  34   with the jQuery Migrate library, as indicated when this option was provided in
  35   MediaWiki 1.24.
  36 * ProfilerStandard and ProfilerSimpleTrace were removed. Make sure that any
  37   StartProfiler.php config is updated to reflect this. Xhprof is available
  38   for zend/hhvm. Also, for hhvm, one can consider using its xenon profiler.
  39 * Default value of $wgSVGConverters['rsvg'] now uses the 'rsvg-convert' binary
  40   rather than 'rsvg'.
  41 * Default value of $wgSVGConverters['ImageMagick'] now uses transparent
  42   background with white fallback color, rather than just white background.
  43  * MediaWikiBagOStuff class removed, make sure any object cache config
  44    uses SqlBagOStuff instead.
  45 * The 'daemonized' flag must be set to true in $wgJobTypeConf for any redis
  46   job queues. This means that mediawiki/services/jobrunner service has to
  47   be installed and running for any such queues to work.
  48
  49 === New features in 1.25 ===
  50 * (T64861) Updated plural rules to CLDR 26. Includes incompatible changes
  51   for plural forms in Russian, Prussian, Tagalog, Manx and several languages
  52   that fall back to Russian.
  53 * (T60139) ResourceLoaderFileModule now supports language fallback
  54   for 'languageScripts'.
  55 * Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
  56   parser output for a content object before links update.
  57 * (T37785) Enhanced recent changes and extended watchlist are now default.
  58   Documentation: https://meta.wikimedia.org/wiki/Help:Enhanced_recent_changes
  59   and https://www.mediawiki.org/wiki/Manual:$wgDefaultUserOptions.
  60 * (T69341) SVG images will no longer be base64-encoded when being embedded
  61   in CSS. This results in slight size increase before gzip compression (due to
  62   percent-encoding), but up to 20% decrease after it.
  63 * Update jStorage to v0.4.12.
  64 * MediaWiki now natively supports page status indicators: icons (or short text
  65   snippets) usually displayed in the top-right corner of the page. They have
  66   been in use on Wikipedia for a long time, implemented using templates and CSS
  67   absolute positioning.
  68   - Basic wikitext syntax: <indicator name="foo">[[File:Foo.svg|20px]]</indicator>
  69   - Usage instructions: https://www.mediawiki.org/wiki/Help:Page_status_indicators
  70   - Adjusting custom skins to support indicators:
  71     https://www.mediawiki.org/wiki/Manual:Skinning#Page_status_indicators
  72 * Edit tokens may now be time-limited: passing a maximum age to
  73   User::matchEditToken will reject any older tokens.
  74 * The debug logging internals have been overhauled, and are now using the
  75   PSR-3 interfaces.
  76 * Update CSSJanus to v1.1.1.
  77 * Update lessphp to v0.5.0.
  78 * Added a hook, "ApiOpenSearchSuggest", to allow extensions to provide extracts
  79   and images for ApiOpenSearch output. The semantics are identical to the
  80   "OpenSearchXml" hook provided by the OpenSearchXml extension.
  81 * PrefixSearchBackend hook now has an $offset parameter. Combined with $limit,
  82   this allows for pagination of prefix results. Extensions using this hook
  83   should implement supporting behavior. Not doing so can result in undefined
  84   behavior from API clients trying to continue through prefix results.
  85 * Update jQuery from v1.11.1 to v1.11.2.
  86 * External libraries installed via composer will now be displayed
  87   on Special:Version in their own section. Extensions or skins that are
  88   installed via composer will not be shown in this section as it is assumed
  89   they will add the proper credits to the skins or extensions section. They
  90   can also be accessed through the API via the new siprop=libraries to
  91   ApiQuerySiteInfo.
  92 * Update QUnit from v1.14.0 to v1.16.0.
  93 * Update Moment.js from v2.8.3 to v2.8.4.
  94 * Special:Tags now allows for manipulating the list of user-modifiable change
  95   tags. Actually modifying the tagging of a revision or log entry is not
  96   implemented yet.
  97 * Added 'managetags' user right and 'ChangeTagCanCreate', 'ChangeTagCanDelete',
  98   and 'ChangeTagCanCreate' hooks to allow for managing user-modifiable change
  99   tags.
 100 * Added 'ChangeTagsListActive' hook, to separate the concepts of "defined" and
 101   "active" formerly conflated by the 'ListDefinedTags' hook.
 102 * Added TemplateParser class that provides a server-side interface to cachable
 103   dynamically-compiled Mustache templates (currently uses lightncandy library).
 104 * Clickable anchors for each section heading in the content are now generated
 105   and appear in the gutter on hovering over the heading.
 106 * Added 'CategoryViewer::doCategoryQuery' and 'CategoryViewer::generateLink' hooks
 107   to allow extensions to override how links to pages are rendered within NS_CATEGORY
 108 * (T19665) Special:WantedPages only lists page which having at least one red link
 109   pointing to it.
 110 * New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
 111   used for conditional registration of API modules.
 112
 113 ==== External libraries ====
 114 * MediaWiki now requires certain external libraries to be installed. In the past
 115   these were bundled inside the Git repository of MediaWiki core, but now they
 116   need to be installed separately. For users using the tarball, this will be taken
 117   care of and no action will be required. Users using Git will either need to use
 118   composer to fetch dependencies or use the mediawiki/vendor repository which includes
 119   all dependencies for MediaWiki core and ones used in Wikimedia deployment. Detailed
 120   instructions can be found at:
 121   https://www.mediawiki.org/wiki/Download_from_Git#Fetch_external_libraries
 122 * The following libraries are now required:
 123 ** psr/log
 124    This library provides the interfaces set by the PSR-3 standard (http://www.php-fig.org/psr/psr-3/)
 125    which are used by MediaWiki internally via the MWLoggerFactory class.
 126    See the structured logging RfC (https://www.mediawiki.org/wiki/Requests_for_comment/Structured_logging)
 127    for more background information.
 128 ** cssjanus/cssjanus
 129    This library was formerly bundled with MediaWiki core and has been removed.
 130    It automatically flips CSS for RTL support.
 131 ** leafo/lessphp
 132    This library was formerly bundled with MediaWiki core and has been removed.
 133    It compiles LESS files into CSS.
 134 ** wikimedia/cdb
 135    This library was formerly a part of MediaWiki core, and has been moved into a separate library.
 136    It provides CDB functions which are used in the Interwiki and Localization caches.
 137    More information about the library can be found at https://www.mediawiki.org/wiki/CDB.
 138
 139 === Bug fixes in 1.25 ===
 140 * (T73003) No additional code will be generated to try to load CSS-embedded
 141   SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
 142 * (T69021) On Special:BookSources, corrected validation of ISBNs (both
 143   10- and 13-digit forms) containing "X".
 144 * Page moving was refactored into a MovePage class. As part of that:
 145 ** The AbortMove hook was removed.
 146 ** MovePageIsValidMove is for extensions to specify whether a page
 147    cannot be moved for technical reasons, and should not be overridden.
 148 ** MovePageCheckPermissions is for checking whether the given user is
 149    allowed to make the move.
 150 ** Title::moveNoAuth() was deprecated. Use the MovePage class instead.
 151 ** Title::moveTo() was deprecated. Use the MovePage class instead.
 152 ** Title::isValidMoveOperation() broken down into MovePage::isValidMove()
 153    and MovePage::checkPermissions().
 154 * (T18530) Multiple autocomments are now formatted in an edit summary.
 155 * (T70361) Autocomments containing "/*" are parsed correctly.
 156 * The Special:WhatLinksHere page linked from 'Number of redirects to this page'
 157   on action=info about a file page does not list file links anymore.
 158 * (T78637) Search bar is not autofocused unless it is empty so that proper scrolling using arrow keys is possible.
 159 * (T50853) Database::makeList() modified to handle 'NULL' separately when building IN clause
 160 * (T85192) Captcha position modified in Usercreate template. As a result:
 161 ** extrafields parameter added to Usercreate.php to insert additional data
 162 ** 'extend' method added to QuickTemplate to append additional values to any field of data array
 163 * (T86974) Several Title methods now load from the database when necessary
 164   (instead of returning incorrect results) even when the page ID is known.
 165 * (T74070) Duplicate search for archived files on file upload now omits the extension.
 166   This requires the fa_sha1 field being populated.
 167
 168 === Action API changes in 1.25 ===
 169 * (T67403) XML tag highlighting is now only performed for formats
 170   "xmlfm" and "wddxfm".
 171 * action=paraminfo supports generalized submodules (modules=query+value),
 172   querymodules and formatmodules are deprecated
 173 * action=paraminfo no longer outputs descriptions and other help text by
 174   default. If needed, it may be requested using the new 'helpformat' parameter.
 175 * action=help has been completely rewritten, and outputs help in HTML
 176   rather than plain text.
 177 * Hitting api.php without specifying an action now displays only the help for
 178   the main module, with links to submodule help.
 179 * API help is no longer displayed on errors.
 180 * 'uselang' is now a recognized API parameter; "uselang=user" may be used to
 181   explicitly select the language from the current user's preferences, and
 182   "uselang=content" may be used to select the wiki's content language.
 183 * Default output format for the API is now jsonfm.
 184 * Simplified continuation will return a "batchcomplete" property in the result
 185   when a batch of pages is complete.
 186 * Pretty-printed HTML output now has nicer formatting and (if available)
 187   better syntax highlighting.
 188 * Deprecated list=deletedrevs in favor of newly-added prop=deletedrevisions and
 189   list=alldeletedrevisions.
 190 * prop=revisions will gracefully continue when given too many revids or titles,
 191   rather than just ignoring the extras.
 192 * prop=revisions will no longer die if rvcontentformat doesn't match a
 193   revision's content model; it will instead warn and omit the content.
 194 * If the user has the 'deletedhistory' right, action=query's revids parameter
 195   will now recognize deleted revids.
 196 * prop=revisions may be used as a generator, generating revids.
 197 * (T68776) format=json results will no longer be corrupted when
 198   $wgMangleFlashPolicy is in effect. format=php results will cleanly return an
 199   error instead of returning invalid serialized data.
 200 * Generators may now return data for the generated pages when used with
 201   action=query.
 202 * Query page data for generator=search and generator=prefixsearch will now
 203   include an "index" field, which may be used by the client for sorting the
 204   search results.
 205 * ApiOpenSearch now supports XML output.
 206 * ApiOpenSearch will now output descriptions and URLs as array indexes 2 and 3
 207   in JSON format.
 208 * (T76051) list=tags will now continue correctly.
 209 * (T76052) list=tags can now indicate whether a tag is defined.
 210 * (T75522) list=prefixsearch now supports continuation
 211 * (T78737) action=expandtemplates can now return page properties.
 212 * (T78690) list=allimages now accepts multiple pipe-separated values
 213   for the 'aimime' parameter.
 214 * prop=info with inprop=protections will now return applicable protection types
 215   with the 'restrictiontypes' key.
 216 * (T85417) When resolving redirects, ApiPageSet will now add the targets of
 217   interwiki redirects to the list of interwiki titles.
 218 * (T85417) When outputting the list of redirect titles, a 'tointerwiki'
 219   property (like the existing 'tofragment' property) will be set.
 220 * Added action=managetags to allow for managing the list of
 221   user-modifiable change tags. Actually modifying the tagging of a revision or
 222   log entry is not implemented yet.
 223 * list=tags has additional properties to indicate 'active' status and tag
 224   sources.
 225 * siprop=libraries was added to ApiQuerySiteInfo to list installed external libraries.
 226 * (T88010) Added action=checktoken, to test a CSRF token's validity.
 227 * (T88010) Added intestactions to prop=info, to allow querying of
 228   Title::userCan() via the API.
 229
 230 === Action API internal changes in 1.25 ===
 231 * ApiHelp has been rewritten to support i18n and paginated HTML output.
 232   Most existing modules should continue working without changes, but should do
 233   the following:
 234   * Add an i18n message "apihelp-{$moduleName}-description" to replace getDescription().
 235   * Add i18n messages "apihelp-{$moduleName}-param-{$param}" for each parameter
 236     to replace getParamDescription(). If necessary, the settings array returned
 237     by getParams() can use the new ApiBase::PARAM_HELP_MSG key to override the
 238     message.
 239   * Implement getExamplesMessages() to replace getExamples().
 240 * Modules with submodules (like action=query) must have their submodules
 241   override ApiBase::getParent() to return the correct parent object.
 242 * The 'APIGetDescription' and 'APIGetParamDescription' hooks are deprecated,
 243   and will have no effect for modules using i18n messages. Use
 244   'APIGetDescriptionMessages' and 'APIGetParamDescriptionMessages' instead.
 245 * Api formatters will no longer be asked to display the help screen on errors.
 246 * ApiMain::getCredits() was removed. The credits are available in the
 247   'api-credits' i18n message.
 248 * ApiFormatBase has been changed to support i18n and syntax highlighting via
 249   extensions with the new 'ApiFormatHighlight' hook. Core syntax highlighting
 250   has been removed.
 251 * ApiFormatBase now always buffers. Output is done when
 252   ApiFormatBase::closePrinter is called.
 253 * Much of the logic in ApiQueryRevisions has been split into ApiQueryRevisionsBase.
 254 * The 'revids' parameter supplied by ApiPageSet will now count deleted
 255   revisions as "good" if the user has the 'deletedhistory' right. New methods
 256   ApiPageSet::getLiveRevisionIDs() and ApiPageSet::getDeletedRevisionIDs() are
 257   provided to access just the live or just the deleted revids.
 258 * Added ApiPageSet::setGeneratorData() and ApiPageSet::populateGeneratorData()
 259   to allow generators to include data in the action=query result.
 260 * The following methods have been deprecated and may be removed in a future
 261   release:
 262   * ApiBase::getDescription
 263   * ApiBase::getParamDescription
 264   * ApiBase::getExamples
 265   * ApiBase::makeHelpMsg
 266   * ApiBase::makeHelpArrayToString
 267   * ApiBase::makeHelpMsgParameters
 268   * ApiFormatBase::setUnescapeAmps
 269   * ApiFormatBase::getWantsHelp
 270   * ApiFormatBase::setHelp
 271   * ApiFormatBase::formatHTML
 272   * ApiFormatBase::setBufferResult
 273   * ApiFormatBase::getDescription
 274   * ApiMain::setHelp
 275   * ApiMain::reallyMakeHelpMsg
 276   * ApiMain::makeHelpMsgHeader
 277   * ApiQueryImageInfo::getPropertyDescriptions
 278 * The following classes have been deprecated and may be removed in a future
 279   release:
 280   * ApiQueryDeletedrevs
 281 * Default type param for ApiQueryWatchlist and ApiQueryRecentChanges has
 282   been changed from all types (e.g. including 'external') to 'edit|new|log'.
 283 * New hooks 'ApiMain::moduleManager' and 'ApiQuery::moduleManager', can be
 284   used for conditional registration of API modules.
 285
 286 === Languages updated in 1.25 ===
 287
 288 MediaWiki supports over 350 languages. Many localisations are updated
 289 regularly. Below only new and removed languages are listed, as well as
 290 changes to languages because of Bugzilla reports.
 291
 292 * (T66440) Kazakh (kk) wikis should no longer forcefully reset the user's
 293   interface language to kk where unexpected.
 294
 295 === Other changes in 1.25 ===
 296 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
 297   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
 298   migration guide for creators and users of custom skins that relied on it.
 299 * Javascript variables 'wgFileCanRotate' and 'wgFileExtensions' now only
 300   available on Special:Upload.
 301 * (T58257) Set site logo from mediawiki.skinning.interface module instead of
 302   inline styles in the HTML.
 303 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
 304 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
 305 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
 306 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
 307 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
 308 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
 309   since 1.20)
 310 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
 311   since 1.20)
 312 * Removed 'jquery.json' module. (deprecated since 1.24)
 313   Use the 'json' module and global JSON object instead.
 314 * Deprecated OutputPage::readOnlyPage() and OutputPage::rateLimited().
 315   Also, the former will now throw an MWException if called with one or more
 316   arguments.
 317 * Removed hitcounters and associated code.
 318 * The "temp" zone of the upload respository is now considered private. If it
 319   already exists (such as under the images/ directory), please make sure that
 320   the directory is not web readable (e.g. via a .htaccess file).
 321 * BREAKING CHANGE: In the XML dump format used by Special:Export and
 322   dumpBackup.php, the <model> and <format> tags now apprear before the <text>
 323   tag, instead of after the <text> and <sha1> tags.
 324   The new schema version is 0.10, the new schema URI is:
 325   https://www.mediawiki.org/xml/export-0.10.xsd
 326 * MWFunction::call() and MWFunction::callArray() were removed, having being
 327   deprecated in 1.22.
 328 * Deprecated the getInternalLinkAttributes, getInternalLinkAttributesObj,
 329   and getInternalLinkAttributes methods in Linker, and removed
 330   getExternalLinkAttributes method, which was deprecated in MediaWiki 1.18.
 331 * Removed Sites class, which was deprecated in 1.21 and replaced by SiteSQLStore.
 332 * The mw.api.getToken() method now uses action=query?meta=tokens. This will now
 333   fail for custom tokens registered only via the deprecated ApiTokensGetTokenTypes
 334   hook. The ApiQueryTokensRegisterTypes hook should be used for this to work.
 335 * Added wgRelevantArticleId to the client-side config, for use on special pages.
 336 * Deprecated the TitleIsCssOrJsPage hook. Superseded by the
 337   ContentHandlerDefaultModelFor hook since MediaWiki 1.21.
 338 * Deprecated the TitleIsWikitextPage hook. Superseded by the
 339   ContentHandlerDefaultModelFor hook since MediaWiki 1.21.
 340 * Changed parsing of variables in schema (.sql) files:
 341 ** The substituted values are no longer parsed. (Formerly, several passes
 342    were made for each variable, so depending on the order in which variables
 343    were defined, variables might have been found inside encoded values. This
 344    is no longer the case.)
 345 ** Variables are no longer string encoded when the /*$var*/ syntax is used.
 346    If string encoding is necessary, use the '{$var}' syntax instead.
 347 ** Variable names must only consist of one or more of the characters
 348    "A-Za-z0-9_".
 349 ** In source text of the form '{$A}'{$B}' or `{$A}`{$B}`, where variable A
 350    does not exist yet variable B does, the latter may not be replaced.
 351    However, this difference is unlikely to arise in practice.
 352 * (T67278) RFC, PMID, and ISBN "magic links" must be surrounded by non-word
 353   characters on both sides.
 354 * The FormatAutocomments hook will now receive $pre and $post as booleans,
 355   rather than as strings that must be prepended or appended to $comment.
 356 * (T30950, T31025) RFC, PMID, and ISBN "magic links" can no longer contain
 357   newlines; but they can contain &nbsp; and other non-newline whitespace.
 358 * The 'mediawiki.action.edit' ResourceLoader module no longer generates the edit
 359   toolbar, which has been moved to a separate 'mediawiki.toolbar' module. If you
 360   relied on this behavior, update your scripts' dependencies.
 361 * HTMLForm's 'vform' display style has been separated to a subclass. Therefore:
 362   * HTMLForm::isVForm() is now deprecated.
 363   * You can no longer do this:
 364       $form = new HTMLForm( … );
 365       $form->setDisplayFormat( 'vform' ); // throws exception
 366     Instead, do this:
 367       $form = HTMLForm::factory( 'vform', … );
 368 * Deprecated Revision methods getRawUser(), getRawUserText() and getRawComment().
 369 * BREAKING CHANGE: mediawiki.user.generateRandomSessionId:
 370   The alphabet of the prior string returned was A-Za-z0-9 and now it is 0-9A-F
 371 * (T87504) Avoid serving SVG background-images in CSS for Opera 12, which
 372   renders them incorrectly when combined with border-radius or background-size.
 373 * Removed maintenance script dumpSisterSites.php.
 374
 375 == Compatibility ==
 376
 377 MediaWiki 1.25 requires PHP 5.3.3 or later. There is experimental support for
 378 HHVM 3.3.0.
 379
 380 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 381 support for them is somewhat less mature. There is experimental support for
 382 Oracle and Microsoft SQL Server.
 383
 384 The supported versions are:
 385
 386 * MySQL 5.0.2 or later
 387 * PostgreSQL 8.3 or later
 388 * SQLite 3.3.7 or later
 389 * Oracle 9.0.1 or later
 390 * Microsoft SQL Server 2005 (9.00.1399)
 391
 392 == Upgrading ==
 393
 394 1.25 has several database changes since 1.24, and will not work without schema
 395 updates. Note that due to changes to some very large tables like the revision
 396 table, the schema update may take quite long (minutes on a medium sized site,
 397 many hours on a large site).
 398
 399 If upgrading from before 1.11, and you are using a wiki as a commons
 400 repository, make sure that it is updated as well. Otherwise, errors may arise
 401 due to database schema changes.
