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