 160 == Compatibility ==
 161 MediaWiki 1.31 requires PHP 5.5.9 or later. There is experimental support for
 162 HHVM 3.6.5 or later.
 163
 164 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 165 but support for them is somewhat less mature. There is experimental support for
 166 Oracle and Microsoft SQL Server.
 167
 168 The supported versions are:
 169
 170 * MySQL 5.0.3 or later
 171 * PostgreSQL 8.3 or later

 173 * Oracle 9.0.1 or later
 174 * Microsoft SQL Server 2005 (9.00.1399)
 175
 176 == Upgrading ==
 177 1.31 has several database changes since 1.30, and will not work without schema
 178 updates. Note that due to changes to some very large tables like the revision
 179 table, the schema update may take quite long (minutes on a medium sized site,
 180 many hours on a large site).
 181
 182 Don't forget to always back up your database before upgrading!
 183
 184 See the file UPGRADE for more detailed upgrade instructions, including
 185 important information when upgrading from versions prior to 1.11.
