 215 == Compatibility ==
 216
 217 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 218
 219 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 220 support for them is somewhat less mature. There is experimental support for IBM
 221 DB2 and Microsoft SQL Server.
 222
 223 The supported versions are:
 224
 225 * MySQL 4.0 or later
 226 * PostgreSQL 8.3 or later
 227 * SQLite 3
 228 * Oracle 9.0.1 or later
 229
 230 == Upgrading ==
 231
 232 1.19 has several database changes since 1.17, and will not work without schema
 233 updates.
 234
 235 If upgrading from before 1.11, and you are using a wiki as a commons
 236 repository, make sure that it is updated as well. Otherwise, errors may arise
 237 due to database schema changes.
 238
 239 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 240 new database fields are filled with data.
 241
 242 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 243 changes are made, and there is a slightly higher chance that things could
 244 break. Don't forget to always back up your database before upgrading!
 245
 246 See the file UPGRADE for more detailed upgrade instructions.
 247
 248 For notes on 1.15.x and older releases, see HISTORY.
 249
