  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.

  32   usernames formed like "iw>Example" as interwiki links, as if by wikitext like

  34 * (T111605) The 'ImportHandleUnknownUser' hook allows extensions to auto-create
  35   users during an import.

 156 == Compatibility ==
 157 MediaWiki 1.31 requires PHP 5.5.9 or later. There is experimental support for
 158 HHVM 3.6.5 or later.
 159
 160 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 161 but support for them is somewhat less mature. There is experimental support for
 162 Oracle and Microsoft SQL Server.
 163
 164 The supported versions are:
 165
 166 * MySQL 5.0.3 or later
 167 * PostgreSQL 8.3 or later
 168 * SQLite 3.3.7 or later
 169 * Oracle 9.0.1 or later
 170 * Microsoft SQL Server 2005 (9.00.1399)
 171
 172 == Upgrading ==
 173 1.31 has several database changes since 1.30, and will not work without schema
 174 updates. Note that due to changes to some very large tables like the revision
 175 table, the schema update may take quite long (minutes on a medium sized site,
 176 many hours on a large site).
 177
 178 Don't forget to always back up your database before upgrading!
 179
 180 See the file UPGRADE for more detailed upgrade instructions, including
 181 important information when upgrading from versions prior to 1.11.
