   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 * Removed SkinTemplateSetupPageCss hook; use BeforePageDisplay instead.
  15 * (bug 27132) movefile right granted by default to registered users.
  16 * Default cookie lifetime ($wgCookieExpiration) is increased to 180 days.
  17 * (bug 31204) Removed old user.user_options
  18 * $wgMaxImageArea now applies to jpeg files if they are not scaled with
  19   ImageMagick.
  20 * Introduced $wgQueryPageDefaultLimit (defaults to 50) for the number of
  21   items to show by default on query pages (special pages such as Whatlinkshere).
  22
  23 === New features in 1.19 ===
  24 * (bug 19838) Possibility to get all interwiki prefixes if the interwiki
  25   cache is used.
  26 * $wgDnsBlacklistUrls now accepts an array with url and key as the
  27   elements to work with DNSBLs that require keys, such as
  28   Project Honeypot.
  29 * (bug 30022) Add support for custom loadScript sources to ResourceLoader.
  30 * (bug 19052) Unicode space separator characters (Zs) now terminates external
  31   links and images links.
  32 * (bug 30160) Add public method to mw.loader to get module names from registry.
  33 * (bug 15558) Parameters to special pages included in wikitext can now be passed
  34   as with templates.
  35 * Installer now issues a warning if mod_security is present.
  36 * (bug 29455) Add support for a filter callback function in jQuery byteLimit
  37   plugin.
  38 * Extensions can now participate in the extraction of titles from url paths
  39 * Added two new GetLocalURL hooks to better serve extensions working on a
  40   limited type of titles.
  41 * Added a --no-updates flag to importDump.php that skips updating the links
  42   tables.
  43 * Most presentational html attributes like valign are now converted to inline
  44   css style rules. These attributes were removed from html5 and so we clean
  45   them up when $wgHtml5 is enabled. This can be disabled using
  46   $wgCleanupPresentationalAttributes.
  47 * Magic words (time and number-formatting ones, plus DIRECTIONMARK, but not
  48   NAMESPACE) now depend on the page content language instead of the site
  49   language. In theory this sets the right magic words in system messages,
  50   although they are not used there.
  51 * (bug 30451) Add page_props to RefreshLinks::deleteLinksFromNonexistent
  52 * (bug 30450) Clear page_props table on page deletion

  55   generating sitemaps

  57   'class') in the Html helper class.
  58 * (bug 26470) Add checkered background image on hover on files pages.
  59 * (bug 30774) mediawiki.html: Add support for numbers and booleans in the
  60   attribute values and element contents.
  61 * Conversion script between Tifinagh and Latin for the Tachelhit language
  62 * (bug 16755) Add options 'noreplace' and 'noerror' to {{DEFAULTSORT:...}}
  63   to stop it from replace an already existing default sort, and suppress error.
  64 * (bug 18578) Rewrote revision delete related messages to allow better
  65   localisation
  66 * (bug 30364) LanguageConverter now depends on the page content language
  67   instead of the wiki content language
  68 * Jump links will now be usable in css-capable browsers instead of only
  69   in outdated text browsers.
  70 * New common*.css files usable by skins instead of having to copy piles
  71   of generic styles from MonoBook or Vector's css.
  72 * Some deprecated presentational html attributes will now be automatically
  73   converted to css.
  74 * (bug 31297) Add support for namespaces in Special:RecentChanges subpage filter
  75   syntax.

  80   real name in some parts of the interface instead of a username.

  82 * getUserPermissionsErrors and getUserPermissionsErrorsExpensive hooks are now
  83   also called when checking for 'read' permission
  84 * Introduce $wgEnableSearchContributorsByIP which controls whether searching
  85   for an IP address redirects to the contributions list for that IP
  86
  87 === Bug fixes in 1.19 ===

 181 == Compatibility ==
 182
 183 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 184
 185 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 186 support for them is somewhat less mature. There is experimental support for IBM
 187 DB2 and Microsoft SQL Server.
 188
 189 The supported versions are:
 190
 191 * MySQL 4.0 or later
 192 * PostgreSQL 8.3 or later
 193 * SQLite 3
 194 * Oracle 9.0.1 or later
 195
 196 == Upgrading ==
 197
 198 1.19 has several database changes since 1.18, and will not work without schema
 199 updates.
 200
 201 If upgrading from before 1.11, and you are using a wiki as a commons
 202 repository, make sure that it is updated as well. Otherwise, errors may arise
 203 due to database schema changes.
 204
 205 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 206 new database fields are filled with data.
 207
 208 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 209 changes are made, and there is a slightly higher chance that things could
 210 break. Don't forget to always back up your database before upgrading!
 211
 212 See the file UPGRADE for more detailed upgrade instructions.
 213
 214 For notes on 1.17.x and older releases, see HISTORY.
