 173 == Compatibility ==
 174
 175 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 176
 177 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 178 support for them is somewhat less mature. There is experimental support for IBM
 179 DB2 and Microsoft SQL Server.
 180
 181 The supported versions are:
 182
 183 * MySQL 4.0 or later
 184 * PostgreSQL 8.3 or later
 185 * SQLite 3
 186 * Oracle 9.0.1 or later
 187
 188 == Upgrading ==
 189
 190 1.19 has several database changes since 1.17, and will not work without schema
 191 updates.
 192
 193 If upgrading from before 1.11, and you are using a wiki as a commons
 194 repository, make sure that it is updated as well. Otherwise, errors may arise
 195 due to database schema changes.
 196
 197 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 198 new database fields are filled with data.
 199
 200 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 201 changes are made, and there is a slightly higher chance that things could
 202 break. Don't forget to always back up your database before upgrading!
 203
 204 See the file UPGRADE for more detailed upgrade instructions.
 205
 206 For notes on 1.15.x and older releases, see HISTORY.
