  10 MediaWiki 1.19 is an alpha-quality branch and is not recommended for use in
  11 production.
  12
  13 === Configuration changes in 1.19 ===
  14 * Changed LoginAuthenticateAudit hook so that it may be called before a
  15   valid user is available.  In those cases, an anonymouse user object
  16   will be supplied.
  17 * Removed SkinTemplateSetupPageCss hook; use BeforePageDisplay instead.
  18 * (bug 27132) movefile right granted by default to registered users.
  19 * Default cookie lifetime ($wgCookieExpiration) is increased to 180 days.
  20 * (bug 31204) Removed old user.user_options.
  21 * $wgMaxImageArea now applies to jpeg files if they are not scaled with
  22   ImageMagick.
  23 * Introduced $wgQueryPageDefaultLimit (defaults to 50) for the number of
  24   items to show by default on query pages (special pages such as Whatlinkshere).
  25 * (bug 32470) Increase the length of ug_group.
  26 * (bug 32239) Removed wgEnableTooltipsAndAccesskeys.
  27 * Removed $wgVectorShowVariantName.

  29 === New features in 1.19 ===
  30 * (bug 19838) Possibility to get all interwiki prefixes if the interwiki
  31   cache is used.
  32 * $wgDnsBlacklistUrls now accepts an array with url and key as the
  33   elements to work with DNSBLs that require keys, such as
  34   Project Honeypot.
  35 * (bug 30022) Add support for custom loadScript sources to ResourceLoader.
  36 * (bug 19052) Unicode space separator characters (Zs) now terminates external
  37   links and images links.
  38 * (bug 30160) Add public method to mw.loader to get module names from registry.

  46 * Added a --no-updates flag to importDump.php that skips updating the links
  47   tables.

  52 * Magic words (time and number-formatting ones, plus DIRECTIONMARK, but not

  67 * (bug 16755) Add options 'noreplace' and 'noerror' to {{DEFAULTSORT:...}}
  68   to stop it from replace an already existing default sort, and suppress error.

  70   localisation.
  71 * (bug 30364) LanguageConverter now depends on the page content language
  72   instead of the wiki content language.
  73 * Jump links will now be usable in css-capable browsers instead of only
  74   in outdated text browsers.
  75 * New common*.css files usable by skins instead of having to copy piles
  76   of generic styles from MonoBook or Vector's css.

  93 * (bug 24037) Add byte length of revision to Special:Contributions.
  94 * (bug 1672) Added $wgDisableUploadScriptChecks to allow uploading of files
  95   containing HTML or JS. DISABLING THESE CHECKS IS VERY DANGEROUS.

  97   and adding paths to the PathRouter.
  98 * (bug 32666) Special:ActiveUsers now allows a subpage to be used as the

 239 == Compatibility ==
 240
 241 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 242
 243 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 244 support for them is somewhat less mature. There is experimental support for IBM
 245 DB2 and Microsoft SQL Server.
 246
 247 The supported versions are:
 248
 249 * MySQL 5.0.2 or later
 250 * PostgreSQL 8.3 or later
 251 * SQLite 3
 252 * Oracle 9.0.1 or later
 253
 254 == Upgrading ==
 255
 256 1.19 has several database changes since 1.18, and will not work without schema
 257 updates.
 258
 259 If upgrading from before 1.11, and you are using a wiki as a commons
 260 repository, make sure that it is updated as well. Otherwise, errors may arise
 261 due to database schema changes.
 262
 263 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 264 new database fields are filled with data.
 265
 266 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 267 changes are made, and there is a slightly higher chance that things could
 268 break. Don't forget to always back up your database before upgrading!
 269
 270 See the file UPGRADE for more detailed upgrade instructions.
 271
 272 For notes on 1.18.x and older releases, see HISTORY.
 273
