   8 THIS IS NOT A RELEASE YET
   9
  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
  28 === New features in 1.19 ===
  29 * (bug 19838) Possibility to get all interwiki prefixes if the interwiki
  30   cache is used.
  31 * $wgDnsBlacklistUrls now accepts an array with url and key as the
  32   elements to work with DNSBLs that require keys, such as
  33   Project Honeypot.
  34 * (bug 30022) Add support for custom loadScript sources to ResourceLoader.
  35 * (bug 19052) Unicode space separator characters (Zs) now terminates external
  36   links and images links.
  37 * (bug 30160) Add public method to mw.loader to get module names from registry.
  38 * (bug 15558) Parameters to special pages included in wikitext can now be passed

  41 * (bug 29455) Add support for a filter callback function in jQuery byteLimit
  42   plugin.

  44   limited type of titles.
  45 * Added a --no-updates flag to importDump.php that skips updating the links
  46   tables.
  47 * Most presentational html attributes like valign are now converted to inline
  48   css style rules. These attributes were removed from html5 and so we clean
  49   them up when $wgHtml5 is enabled. This can be disabled using
  50   $wgCleanupPresentationalAttributes.
  51 * Magic words (time and number-formatting ones, plus DIRECTIONMARK, but not
  52   NAMESPACE) now depend on the page content language instead of the site
  53   language. In theory this sets the right magic words in system messages,
  54   although they are not used there.

  64   attribute values and element contents.
  65 * Conversion script between Tifinagh and Latin for the Tachelhit language.
  66 * (bug 16755) Add options 'noreplace' and 'noerror' to {{DEFAULTSORT:...}}
  67   to stop it from replace an already existing default sort, and suppress error.
  68 * (bug 18578) Rewrote revision delete related messages to allow better
  69   localisation.
  70 * (bug 30364) LanguageConverter now depends on the page content language
  71   instead of the wiki content language.
  72 * Jump links will now be usable in css-capable browsers instead of only
  73   in outdated text browsers.
  74 * New common*.css files usable by skins instead of having to copy piles
  75   of generic styles from MonoBook or Vector's css.
  76 * Some deprecated presentational html attributes will now be automatically
  77   converted to css.

  90 * (bug 8859) Database::update should take array of tables too.
  91 * (bug 19698) Inverse selection for Special:Contributions.
  92 * (bug 24037) Add byte length of revision to Special:Contributions.
  93 * (bug 1672) Added $wgDisableUploadScriptChecks to allow uploading of files
  94   containing HTML or JS. DISABLING THESE CHECKS IS VERY DANGEROUS.
  95 * New path mappings can be added using the WebRequestPathInfoRouter hook
  96   and adding paths to the PathRouter.
  97 * (bug 32666) Special:ActiveUsers now allows a subpage to be used as the
  98   username (eg. Special:ActiveUsers/Username)
  99 * New JavaScript variable wgPageContentLanguage
 100 * Added new debugging toolbar, enabled with $wgDebugToolbar
 101 * Differences in the history page now uses slightly better colors for people

 228 == Compatibility ==
 229
 230 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 231
 232 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 233 support for them is somewhat less mature. There is experimental support for IBM
 234 DB2 and Microsoft SQL Server.
 235
 236 The supported versions are:
 237
 238 * MySQL 5.0.2 or later
 239 * PostgreSQL 8.3 or later
 240 * SQLite 3
 241 * Oracle 9.0.1 or later
 242
 243 == Upgrading ==
 244
 245 1.19 has several database changes since 1.18, and will not work without schema
 246 updates.
 247
 248 If upgrading from before 1.11, and you are using a wiki as a commons
 249 repository, make sure that it is updated as well. Otherwise, errors may arise
 250 due to database schema changes.
 251
 252 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 253 new database fields are filled with data.
 254
 255 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 256 changes are made, and there is a slightly higher chance that things could
 257 break. Don't forget to always back up your database before upgrading!
 258
 259 See the file UPGRADE for more detailed upgrade instructions.
 260
 261 For notes on 1.18.x and older releases, see HISTORY.
