  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.

  17   not have the right to mark things patrolled.

  22 * Wikimedia\Rdbms\IDatabase->select() and similar methods now support
  23   joins with parentheses for grouping.

  25   Html class now provides helper methods for messageBox, successBox, errorBox and
  26   warningBox generation.

  29 * (T20209) Linker (used on history pages, log pages, and so on) will display
  30   usernames formed like "iw>Example" as interwiki links, as if by wikitext like
  31   [[iw:User:Example|iw>Example]].
  32 * (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
  33   users during an import.

 137 == Compatibility ==
 138 MediaWiki 1.31 requires PHP 5.5.9 or later. There is experimental support for
 139 HHVM 3.6.5 or later.
 140
 141 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 142 but support for them is somewhat less mature. There is experimental support for
 143 Oracle and Microsoft SQL Server.
 144
 145 The supported versions are:
 146
 147 * MySQL 5.0.3 or later
 148 * PostgreSQL 8.3 or later
 149 * SQLite 3.3.7 or later
 150 * Oracle 9.0.1 or later
 151 * Microsoft SQL Server 2005 (9.00.1399)
 152
 153 == Upgrading ==
 154 1.31 has several database changes since 1.30, and will not work without schema
 155 updates. Note that due to changes to some very large tables like the revision
 156 table, the schema update may take quite long (minutes on a medium sized site,
 157 many hours on a large site).
 158
 159 Don't forget to always back up your database before upgrading!
 160
 161 See the file UPGRADE for more detailed upgrade instructions, including
 162 important information when upgrading from versions prior to 1.11.
