RELEASE-NOTES-1.31

   1 == MediaWiki 1.31 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.31 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.31 ===
   9 * $wgEnableAPI and $wgEnableWriteAPI are now deprecated and will be removed in
  10   a future version. The API is now considered to be stable, secure and
  11   essential.
  12 * $wgUsejQueryThree was removed, as it is now the default. This was documented as a
  13   temporary variable during the migration period, deprecated since 1.29.
  14 * $wgLogoHD has been updated to support svg images and uses $wgLogo where
  15   possible for fallback images such as png.
  16 * (T44246) $wgFilterLogTypes will no longer ignore 'patrol' when user does
  17   not have the right to mark things patrolled.
  18 * Wikis that contain imported revisions or CentralAuth global blocks should run
  19   maintenance/cleanupUsersWithNoId.php.
  20 * $wgResourceLoaderMinifierStatementsOnOwnLine and $wgResourceLoaderMinifierMaxLineLength
  21   were removed (deprecated since 1.27).
  22 * (T180921) $wgReferrerPolicy now supports having fallbacks for browsers that are not
  23   using the latest version of the Referrer Policy specification.
  24 * $wgFragmentMode is now set to [ 'legacy', 'html5' ] by default. This is a first step of
  25   migration to human-readable section IDs that will later result in 'html5' being the
  26   default mode.
  27
  28 === New features in 1.31 ===
  29 * Wikimedia\Rdbms\IDatabase->select() and similar methods now support
  30   joins with parentheses for grouping.
  31 * As a first pass in standardizing dialog boxes across the MediaWiki product,
  32   Html class now provides helper methods for messageBox, successBox, errorBox and
  33   warningBox generation.
  34 * (T9240) Imports will now record unknown (and, optionally, known) usernames in
  35   a format like "iw>Example".
  36 * (T20209) Linker (used on history pages, log pages, and so on) will display
  37   usernames formed like "iw>Example" as interwiki links, as if by wikitext like
  38   [[iw:User:Example|iw>Example]].
  39 * (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
  40   users during an import.
  41 * Added a hook, ParserOutputPostCacheTransform, to allow extensions to affect
  42   the ParserOutput::getText() post-cache transformations.
  43 * Added a hook, UploadForm:getInitialPageText, to allow extensions to alter the
  44   initial page text for file uploads.
  45 * (T181651) The info page for File pages now displays the file's base-36 SHA1
  46   hash value in the table of basic information.

 185
 186 == Compatibility ==
 187 MediaWiki 1.31 requires PHP 5.5.9 or later. Although HHVM 3.18.5 or later is supported,
 188 it is generally advised to use PHP 5.5.9 or later for long term support.
 189
 190 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 191 but support for them is somewhat less mature. There is experimental support for
 192 Oracle and Microsoft SQL Server.
 193
 194 The supported versions are:
 195
 196 * MySQL 5.0.3 or later
 197 * PostgreSQL 8.3 or later
 198 * SQLite 3.3.7 or later
 199 * Oracle 9.0.1 or later
 200 * Microsoft SQL Server 2005 (9.00.1399)
 201
 202 == Upgrading ==
 203 1.31 has several database changes since 1.30, and will not work without schema
 204 updates. Note that due to changes to some very large tables like the revision
 205 table, the schema update may take quite long (minutes on a medium sized site,
 206 many hours on a large site).
 207
 208 Don't forget to always back up your database before upgrading!
 209
 210 See the file UPGRADE for more detailed upgrade instructions, including
 211 important information when upgrading from versions prior to 1.11.
