   8 THIS IS NOT A RELEASE YET

  10 MediaWiki 1.20 is an alpha-quality branch and is not recommended for use in
  11 production.

  13 === PHP 5.3 now required ===

 173 === Languages updated in 1.20 ===
 174
 175 MediaWiki supports over 350 languages. Many localisations are updated
 176 regularly. Below only new and removed languages are listed, as well as
 177 changes to languages because of Bugzilla reports.
 178
 179 * Emilian (egl) added.
 180 * Tornedalen Finnish (fit) added.
 181 * Mizo (lus) added.
 182 * Santali (sat) added.
 183 * (bug 34192) Namespace gender aliases for Albanian languages (sq & aln).
 184 * (bug 35541) Namespace gender aliases for Croatian (hr).
 185 * (bug 36012) Space in $separatorTransformTable should be non-breaking in
 186   Portuguese, Esperanto and Udmurt.
 187
 188 === Other changes in 1.20 ===
 189 * The user_token field is now left empty until a user attempts to login and
 190   cookies need to be set. It is also now possible to reset every user's
 191   user_token simply by clearing the values in the user_token column.
 192 * Removed ./tests/qunit/index.html from core. It wasn't actively maintained and
 193   has been made obsolete when [[Special:JavaScriptTest/qunit]] was introduced,
 194   which actually uses ResourceLoader, LocalSettings and the Skin.
 195 * Removed $wgDBtransactions global. This was only checked in one class
 196   and only applies to MyISAM or similar DBs. Those should only be used
 197   for archived sites anyway. We can't get edit conflicts on such sites,
 198   so the WikiPage code wasn't useful there either.
 199
 200 == Compatibility ==
 201
 202 MediaWiki 1.20 requires PHP 5.3.2. PHP 4 is no longer supported.
 203
 204 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 205 support for them is somewhat less mature. There is experimental support for IBM
 206 DB2 and Oracle.
 207
 208 The supported versions are:
 209
 210 * MySQL 5.0.2 or later
 211 * PostgreSQL 8.3 or later
 212 * SQLite 3.3.7 or later
 213 * Oracle 9.0.1 or later
 214
 215 == Upgrading ==
 216
 217 1.20 has several database changes since 1.19, and will not work without schema
 218 updates.
 219
 220 If upgrading from before 1.11, and you are using a wiki as a commons
 221 repository, make sure that it is updated as well. Otherwise, errors may arise
 222 due to database schema changes.
 223
 224 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 225 new database fields are filled with data.
 226
 227 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 228 changes are made, and there is a slightly higher chance that things could
 229 break. Don't forget to always back up your database before upgrading!
 230
 231 See the file UPGRADE for more detailed upgrade instructions.
 232
 233 For notes on 1.19.x and older releases, see HISTORY.
 234
 235 == Online documentation ==
 236
 237 Documentation for both end-users and site administrators is available on
 238 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 239 for pages that explicitly state that their contents are in the public domain):
 240
 241         https://www.mediawiki.org/wiki/Documentation
 242
 243 == Mailing list ==
 244
 245 A mailing list is available for MediaWiki user support and discussion:
 246
 247         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 248
 249 A low-traffic announcements-only list is also available:
 250
 251         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 252
 253 It's highly recommended that you sign up for one of these lists if you're
 254 going to run a public MediaWiki, so you can be notified of security fixes.
 255
 256 == IRC help ==
 257
 258 There's usually someone online in #mediawiki on irc.freenode.net.
