 164 == Compatibility ==
 165
 166 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 167
 168 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 169 support for them is somewhat less mature. There is experimental support for IBM
 170 DB2 and Microsoft SQL Server.
 171
 172 The supported versions are:
 173
 174 * MySQL 4.0 or later
 175 * PostgreSQL 8.3 or later
 176 * SQLite 3
 177 * Oracle 9.0.1 or later
 178
 179 == Upgrading ==
 180
 181 1.19 has several database changes since 1.17, and will not work without schema
 182 updates.
 183
 184 If upgrading from before 1.11, and you are using a wiki as a commons
 185 repository, make sure that it is updated as well. Otherwise, errors may arise
 186 due to database schema changes.
 187
 188 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 189 new database fields are filled with data.
 190
 191 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 192 changes are made, and there is a slightly higher chance that things could
 193 break. Don't forget to always back up your database before upgrading!
 194
 195 See the file UPGRADE for more detailed upgrade instructions.
 196
 197 For notes on 1.15.x and older releases, see HISTORY.
 198
