 169 == Compatibility ==
 170 MediaWiki 1.31 requires PHP 5.5.9 or later. Although HHVM 3.18.5 or later is supported,
 171 it is generally advised to use PHP 5.5.9 or later for long term support.
 172
 173 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 174 but support for them is somewhat less mature. There is experimental support for
 175 Oracle and Microsoft SQL Server.
 176
 177 The supported versions are:
 178
 179 * MySQL 5.0.3 or later
 180 * PostgreSQL 8.3 or later
 181 * SQLite 3.3.7 or later
 182 * Oracle 9.0.1 or later
 183 * Microsoft SQL Server 2005 (9.00.1399)
 184
 185 == Upgrading ==
 186 1.31 has several database changes since 1.30, and will not work without schema
 187 updates. Note that due to changes to some very large tables like the revision
 188 table, the schema update may take quite long (minutes on a medium sized site,
 189 many hours on a large site).
 190
 191 Don't forget to always back up your database before upgrading!
 192
 193 See the file UPGRADE for more detailed upgrade instructions, including
 194 important information when upgrading from versions prior to 1.11.
