102 === Important pre-upgrade notes for 1.31 ===
103 * If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply
104 schema changes, and cannot have downtime to run migrateArchiveText.php and
105 apply patch-drop-ar_text.sql manually, you'll have to apply a default value
106 to the ar_text and ar_flags columns of the archive table or make those
107 columns nullable before upgrading to MediaWiki 1.31.
108 maintenance/archives/patch-nullable-ar_text.sql shows how to do this for MySQL.
109 * The CologneBlue and Modern skins are no longer bundled with the tarball. You
110 will need to remove the wfLoadSkin() calls from your LocalSettings.php or
111 download them separately
112 (<https://www.mediawiki.org/wiki/Special:SkinDistributor>).
114 === Configuration changes in 1.31 ===
115 * $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
116 a future version. The API is now considered to be stable, secure and
118 * $wgUsejQueryThree was removed, as it is now the default. This was documented
119 as a temporary variable during the migration period, deprecated since 1.29.
120 * $wgLogoHD has been updated to support svg images and uses $wgLogo where
121 possible for fallback images such as png.
122 * (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does not
123 have the right to mark things patrolled.
124 * Wikis that contain imported revisions or CentralAuth global blocks should run
125 maintenance/cleanupUsersWithNoId.php.
126 * The configuration settings $wgResourceLoaderMinifierStatementsOnOwnLine and
127 $wgResourceLoaderMinifierMaxLineLength, deprecated since 1.27, were removed.
128 * (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that
129 are not using the latest version of the Referrer Policy specification.
130 * $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a
131 first step of migration to human-readable section IDs that will later result
132 in 'html5' being the default mode.
133 * CACHE_ACCEL now only supports APC(u) or WinCache. XCache support was removed
134 as upstream is inactive and has no plans to move to PHP 7.
135 * The old CategorizedRecentChanges feature, including its related configuration
136 option $wgAllowCategorizedRecentChanges, has been removed.
137 * (T188472) The 'comma' value for $wgArticleCountMethod is no longer supported
138 for performance reasons, and installations with this setting will now work as
139 if it was configured with 'any'.
140 * (T185753) MediaWiki now defaults to using RemexHtml to tidy up user input,
141 rather than being off by default. If you wish to disable HTML tidying
142 entirely, set $wgTidyConfig to null; if you wish to use the old, deprecated
143 Tidy external binary, both set $wgTidyConfig to null and $wgUseTidy to true.
144 * $wgLogAutopatrol now defaults to false instead of true.
145 * $wgValidateAllHtml was removed and will be ignored.
146 * $wgScriptExtension, deprecated and ignored since 1.25, was removed. See the
147 1.25 release notes for more information.
148 * $wgUseAjax is now marked as deprecated, just like the deprecated AJAX
149 framework that it enables. Some extensions mistakenly used this to check
150 whether any AJAX functionality at all should be enabled, further making this
151 problematic to retain.
152 * $wgDBmysql5 is now deprecated, and will be removed in a future version. It
153 has been marked as experimental ever since it was introduced.
155 === New features in 1.31 ===
156 * (T76554) User sub-pages named ….json are now protected in the same way that
157 ….js and ….css pages are, so that configuration options can safely be placed
159 * Wikimedia\Rdbms\IDatabase->select() and similar methods now support joins
160 with parentheses for grouping.
161 * As a first pass in standardizing dialog boxes across the MediaWiki product,
162 Html class now provides helper methods for messageBox, successBox, errorBox
163 and warningBox generation.
164 * (T9240) Imports will now record unknown (and, optionally, known) usernames in
165 a format like "iw>Example".
166 * (T20209) Linker (used on history pages, log pages, and so on) will display
167 usernames formed like "iw>Example" as interwiki links, as if by wikitext like
168 [[iw:User:Example|iw>Example]].
169 * (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
170 users during an import.
171 * Added a hook, ParserOutputPostCacheTransform, to allow extensions to affect
172 the ParserOutput::getText() post-cache transformations.
173 * Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
174 initial page text for file uploads.
175 * (T181651) The info page for File pages now displays the file's base-16 SHA1
176 hash value in the table of basic information.
177 * Style tags with a 'data-mw-deduplicate' attribute will be deduplicated as a
178 ParserOutput::getText() post-cache transformation. This may be disabled by
179 passing 'deduplicateStyles' => false to that method.
180 * The identity of the logged-in or IP "actor" for logged actions is being moved
181 into a new actor table, with the rows in tables such as revision and logging
182 referring to the actor ID instead of storing the user ID and name/IP in
184 * This is currently gated by $wgActorTableSchemaMigrationStage. Most wikis
185 can set this to MIGRATION_NEW and run maintenance/migrateActors.php as
186 soon as any necessary extensions are updated.
187 * Most code accessing rows for logged actions from the database should use
188 the relevant getQueryInfo() methods to get the information needed to build
189 the SQL query. The ActorMigration class may also be used to get feature
190 -flagged information needed to access actor-related fields during the
192 * Added Wikimedia\Rdbms\IDatabase::cancelAtomic(), to roll back an atomic
193 section without having to roll back the whole transaction.
194 * Wikimedia\Rdbms\IDatabase::doAtomicSection(), non-native ::insertSelect(),
195 and non-MySQL ::replace() and ::upsert() no longer roll back the whole
196 transaction on failure.
197 * (T189785) Added a monthly heartbeat ping to the pingback feature.
198 * The CLI installer (maintenance/install.php) learned to detect and include
199 extensions. Pass --with-extensions to enable that feature.
200 * (T184791) rc_patrolled now has three states: "0" for unpatrolled,
201 "1" for manually patrolled and "2" for autopatrolled actions.
202 * Extensions can now set their type to "editor" if they provide an editor or
203 enhance the editing experience.
204 * Extensions can use a PSR-4 autoloader by setting an "AutoloadNamespaces"
205 property in extension.json. See the documentation at
206 <https://mediawiki.org/wiki/Manual:Extension.json/Schema#AutoloadNamespaces>
207 for more details and an example.
208 * (T19099) Tabs which link to pages that don't exist (like those to uncreated
209 discussion pages) now have a tooltip to indicate state, not just colour.
211 === External library changes in 1.31 ===
212 * pear/mail, pear/mail_mime and pear/mail_mime-decode have been moved from
213 suggested to required. These packages now must be installed via composer

504 * The "free" CSS class is now only applied to unbracketed URLs in wikitext.
505 Links written using square brackets will get the class "text" not "free".
506 * RFC 157418: Whitespace is trimmed from wikitext headings, wikitext list items,
507 wikitext table captions, wikitext table headings, wikitext table cells. HTML
508 headings, HTML list items, HTML table captions, HTML table headings, HTML
509 table cells will not have this trimming behavior.
512 MediaWiki 1.31 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is
513 supported, it is generally advised to use PHP 7.0.0 or later for long term
514 support. MediaWiki requires that the mbstring, xml, ctype, json, iconv and
515 fileinfo PHP extensions are loaded to work.
517 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
518 but support for them is somewhat less mature. There is experimental support for
519 Oracle and Microsoft SQL Server.
521 The supported versions are:
523 * MySQL 5.5.8 or later
524 * PostgreSQL 9.2 or later
525 * SQLite 3.3.7 or later
526 * Oracle 9.0.1 or later
527 * Microsoft SQL Server 2005 (9.00.1399)
530 1.31 has several database changes since 1.30, and will not work without schema
531 updates. Note that due to changes to some very large tables like the revision
532 table, the schema update may take quite long (minutes on a medium sized site,
533 many hours on a large site).
535 Don't forget to always back up your database before upgrading!
537 See the file UPGRADE for more detailed upgrade instructions, including
538 important information when upgrading from versions prior to 1.11.
