   8 THIS IS NOT A RELEASE YET
   9
  10 MediaWiki 1.20 is an alpha-quality branch and is not recommended for use in
  11 production.
  12
  13 === PHP 5.3 now required ===
  14 Since 1.20, the lowest supported version of PHP is now 5.3.2. Please
  15 upgrade PHP if you have not done so prior to upgrading MediaWiki.
  16
  17 === Configuration changes in 1.20 ===
  18 * $wgGitRepositoryViewers defines a mapping from Git remote repository to the
  19   Gitweb instance URL used in Special:Version.

  21   using like nginx, lighttpd, and apache over fastcgi. MediaWiki now always extracts
  22   path info from REQUEST_URI if it's available.

 145 === Languages updated in 1.20 ===
 146
 147 MediaWiki supports over 350 languages. Many localisations are updated
 148 regularly. Below only new and removed languages are listed, as well as
 149 changes to languages because of Bugzilla reports.
 150
 151 * Tornedalen Finnish (fit) added.
 152 * Mizo (lus) added.
 153 * Santali (sat) added.
 154 * (bug 34192) Namespace gender aliases for Albanian languages (sq & aln).
 155 * (bug 35541) Namespace gender aliases for Croatian (hr).
 156 * (bug 36012) Space in $separatorTransformTable should be non-breaking in
 157   Portuguese, Esperanto and Udmurt.
 158
 159 === Other changes in 1.20 ===
 160 * The user_token field is now left empty until a user attempts to login and
 161   cookies need to be set. It is also now possible to reset every user's
 162   user_token simply by clearing the values in the user_token column.
 163 * Removed ./tests/qunit/index.html from core. It wasn't actively maintained and
 164   has been made obsolete when [[Special:JavaScriptTest/qunit]] was introduced,
 165   which actually uses ResourceLoader, LocalSettings and the Skin.
 166 * Removed $wgDBtransactions global. This was only checked in one class
 167   and only applies to MyISAM or similar DBs. Those should only be used
 168   for archived sites anyway. We can't get edit conflicts on such sites,
 169   so the WikiPage code wasn't useful there either.
 170
 171 == Compatibility ==
 172
 173 MediaWiki 1.20 requires PHP 5.3.2. PHP 4 is no longer supported.
 174
 175 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 176 support for them is somewhat less mature. There is experimental support for IBM
 177 DB2 and Oracle.
 178
 179 The supported versions are:
 180
 181 * MySQL 5.0.2 or later
 182 * PostgreSQL 8.3 or later
 183 * SQLite 3.3.7 or later
 184 * Oracle 9.0.1 or later
 185
 186 == Upgrading ==
 187
 188 1.20 has several database changes since 1.19, and will not work without schema
 189 updates.
 190
 191 If upgrading from before 1.11, and you are using a wiki as a commons
 192 repository, make sure that it is updated as well. Otherwise, errors may arise
 193 due to database schema changes.
 194
 195 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 196 new database fields are filled with data.
 197
 198 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 199 changes are made, and there is a slightly higher chance that things could
 200 break. Don't forget to always back up your database before upgrading!
 201
 202 See the file UPGRADE for more detailed upgrade instructions.
 203
 204 For notes on 1.19.x and older releases, see HISTORY.
 205
 206 == Online documentation ==
