114 === Important pre-upgrade notes for 1.31 ===
115 * If you're using MySQL, SQLite, or MSSQL, are not using update.php to apply
116 schema changes, and cannot have downtime to run migrateArchiveText.php and
117 apply patch-drop-ar_text.sql manually, you'll have to apply a default value
118 to the ar_text and ar_flags columns of the archive table or make those
119 columns nullable before upgrading to MediaWiki 1.31.
120 maintenance/archives/patch-nullable-ar_text.sql shows how to do this for MySQL.
121 * The CologneBlue and Modern skins are no longer bundled with the tarball. You
122 will need to remove the wfLoadSkin() calls from your LocalSettings.php or
123 download them separately
124 (<https://www.mediawiki.org/wiki/Special:SkinDistributor>).
126 === Configuration changes in 1.31 ===
127 * $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
128 a future version. The API is now considered to be stable, secure and
130 * $wgUsejQueryThree was removed, as it is now the default. This was documented
131 as a temporary variable during the migration period, deprecated since 1.29.
132 * $wgLogoHD has been updated to support svg images and uses $wgLogo where
133 possible for fallback images such as png.
134 * (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does not
135 have the right to mark things patrolled.
136 * Wikis that contain imported revisions or CentralAuth global blocks should run
137 maintenance/cleanupUsersWithNoId.php.
138 * The configuration settings $wgResourceLoaderMinifierStatementsOnOwnLine and
139 $wgResourceLoaderMinifierMaxLineLength, deprecated since 1.27, were removed.
140 * (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that
141 are not using the latest version of the Referrer Policy specification.
142 * $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a
143 first step of migration to human-readable section IDs that will later result
144 in 'html5' being the default mode.
145 * CACHE_ACCEL now only supports APC(u) or WinCache. XCache support was removed
146 as upstream is inactive and has no plans to move to PHP 7.
147 * The old CategorizedRecentChanges feature, including its related configuration
148 option $wgAllowCategorizedRecentChanges, has been removed.
149 * (T188472) The 'comma' value for $wgArticleCountMethod is no longer supported
150 for performance reasons, and installations with this setting will now work as
151 if it was configured with 'any'.
152 * (T185753) MediaWiki now defaults to using RemexHtml to tidy up user input,
153 rather than being off by default. If you wish to disable HTML tidying
154 entirely, set $wgTidyConfig to null; if you wish to use the old, deprecated
155 Tidy external binary, both set $wgTidyConfig to null and $wgUseTidy to true.
156 * $wgLogAutopatrol now defaults to false instead of true.
157 * $wgValidateAllHtml was removed and will be ignored.
158 * $wgScriptExtension, deprecated and ignored since 1.25, was removed. See the
159 1.25 release notes for more information.
160 * $wgUseAjax is now marked as deprecated, just like the deprecated AJAX
161 framework that it enables. Some extensions mistakenly used this to check
162 whether any AJAX functionality at all should be enabled, further making this
163 problematic to retain.
164 * $wgDBmysql5 is now deprecated, and will be removed in a future version. It
165 has been marked as experimental ever since it was introduced.
166 * Fix $magicWords for the Sanskrit language
168 === New features in 1.31 ===
169 * (T76554) User sub-pages named ….json are now protected in the same way that
170 ….js and ….css pages are, so that configuration options can safely be placed
172 * Wikimedia\Rdbms\IDatabase->select() and similar methods now support joins
173 with parentheses for grouping.
174 * As a first pass in standardizing dialog boxes across the MediaWiki product,
175 Html class now provides helper methods for messageBox, successBox, errorBox
176 and warningBox generation.
177 * (T9240) Imports will now record unknown (and, optionally, known) usernames in
178 a format like "iw>Example".
179 * (T20209) Linker (used on history pages, log pages, and so on) will display
180 usernames formed like "iw>Example" as interwiki links, as if by wikitext like
181 [[iw:User:Example|iw>Example]].
182 * (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
183 users during an import.
184 * Added a hook, ParserOutputPostCacheTransform, to allow extensions to affect
185 the ParserOutput::getText() post-cache transformations.
186 * Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
187 initial page text for file uploads.
188 * (T181651) The info page for File pages now displays the file's base-16 SHA1
189 hash value in the table of basic information.
190 * Style tags with a 'data-mw-deduplicate' attribute will be deduplicated as a
191 ParserOutput::getText() post-cache transformation. This may be disabled by
192 passing 'deduplicateStyles' => false to that method.
193 * The identity of the logged-in or IP "actor" for logged actions is being moved
194 into a new actor table, with the rows in tables such as revision and logging
195 referring to the actor ID instead of storing the user ID and name/IP in
197 * This is currently gated by $wgActorTableSchemaMigrationStage. Most wikis
198 can set this to MIGRATION_NEW and run maintenance/migrateActors.php as
199 soon as any necessary extensions are updated.
200 * Most code accessing rows for logged actions from the database should use
201 the relevant getQueryInfo() methods to get the information needed to build
202 the SQL query. The ActorMigration class may also be used to get feature
203 -flagged information needed to access actor-related fields during the
205 * Added Wikimedia\Rdbms\IDatabase::cancelAtomic(), to roll back an atomic
206 section without having to roll back the whole transaction.
207 * Wikimedia\Rdbms\IDatabase::doAtomicSection(), non-native ::insertSelect(),
208 and non-MySQL ::replace() and ::upsert() no longer roll back the whole
209 transaction on failure.
210 * (T189785) Added a monthly heartbeat ping to the pingback feature.
211 * The CLI installer (maintenance/install.php) learned to detect and include
212 extensions. Pass --with-extensions to enable that feature.
213 * (T184791) rc_patrolled now has three states: "0" for unpatrolled,
214 "1" for manually patrolled and "2" for autopatrolled actions.
215 * Extensions can now set their type to "editor" if they provide an editor or
216 enhance the editing experience.
217 * Extensions can use a PSR-4 autoloader by setting an "AutoloadNamespaces"
218 property in extension.json. See the documentation at
219 <https://mediawiki.org/wiki/Manual:Extension.json/Schema#AutoloadNamespaces>
220 for more details and an example.
221 * (T19099) Tabs which link to pages that don't exist (like those to uncreated
222 discussion pages) now have a tooltip to indicate state, not just colour.
224 === External library changes in 1.31 ===
225 * pear/mail, pear/mail_mime and pear/mail_mime-decode have been moved from
226 suggested to required. These packages now must be installed via composer
227 and not via PEAR itself.

518 Links written using square brackets will get the class "text" not "free".
519 * RFC 157418: Whitespace is trimmed from wikitext headings, wikitext list items,
520 wikitext table captions, wikitext table headings, wikitext table cells. HTML
521 headings, HTML list items, HTML table captions, HTML table headings, HTML
522 table cells will not have this trimming behavior.
525 MediaWiki 1.31 requires PHP 7.0.13 or later. Although HHVM 3.18.5 or later is
526 supported, it is generally advised to use PHP 7.0.13 or later for long term
527 support. MediaWiki requires that the mbstring, xml, ctype, json, iconv and
528 fileinfo PHP extensions are loaded to work.
530 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
531 but support for them is somewhat less mature. There is experimental support for
532 Oracle and Microsoft SQL Server.
534 The supported versions are:
536 * MySQL 5.5.8 or later
537 * PostgreSQL 9.2 or later
538 * SQLite 3.3.7 or later
539 * Oracle 9.0.1 or later
540 * Microsoft SQL Server 2005 (9.00.1399)
543 1.31 has several database changes since 1.30, and will not work without schema
544 updates. Note that due to changes to some very large tables like the revision
545 table, the schema update may take quite long (minutes on a medium sized site,
546 many hours on a large site).
548 Don't forget to always back up your database before upgrading!
550 See the file UPGRADE for more detailed upgrade instructions, including
551 important information when upgrading from versions prior to 1.11.
