   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
  19 === New features in 1.19 ===
  20 * (bug 19838) Possibility to get all interwiki prefixes if the interwiki
  21   cache is used.
  22 * $wgDnsBlacklistUrls now accepts an array with url and key as the
  23   elements to work with DNSBLs that require keys, such as
  24   Project Honeypot.
  25 * (bug 30022) Add support for custom loadScript sources to ResourceLoader.
  26 * (bug 19052) Unicode space separator characters (Zs) now terminates external
  27   links and images links.
  28 * (bug 30160) Add public method to mw.loader to get module names from registry.
  29 * (bug 15558) Parameters to special pages included in wikitext can now be passed
  30   as with templates.
  31 * Installer now issues a warning if mod_security is present.
  32 * (bug 29455) Add support for a filter callback function in jQuery byteLimit
  33   plugin.
  34 * Extensions can now participate in the extraction of titles from url paths
  35 * Added two new GetLocalURL hooks to better serve extensions working on a
  36   limited type of titles.
  37 * Added a --no-updates flag to importDump.php that skips updating the links
  38   tables.
  39 * Most presentational html attributes like valign are now converted to inline
  40   css style rules. These attributes were removed from html5 and so we clean
  41   them up when $wgHtml5 is enabled. This can be disabled using
  42   $wgCleanupPresentationalAttributes.
  43 * Magic words (time and number-formatting ones, plus DIRECTIONMARK, but not
  44   NAMESPACE) now depend on the page content language instead of the site
  45   language. In theory this sets the right magic words in system messages,
  46   although they are not used there.
  47 * (bug 30451) Add page_props to RefreshLinks::deleteLinksFromNonexistent
  48 * (bug 30450) Clear page_props table on page deletion
  49 * Hook added to check for exempt from account creation throttle
  50 * (bug 30344) Add configuration variable for setting custom priorities when
  51   generating sitemaps
  52 * (bug 16428) Include permalink in printable version
  53 * (bug 96170) Add array support for space-separated list attributes (like
  54   'class') in the Html helper class.
  55 * (bug 26470) Add checkered background image on hover on files pages.
  56 * (bug 30774) mediawiki.html: Add support for numbers and booleans in the
  57   attribute values and element contents.
  58 * Conversion script between Tifinagh and Latin for the Tachelhit language
  59 * (bug 16755) Add options 'noreplace' and 'noerror' to {{DEFAULTSORT:...}}
  60   to stop it from replace an already existing default sort, and suppress error.
  61 * (bug 18578) Rewrote revision delete related messages to allow better
  62   localisation
  63 * (bug 30364) LanguageConverter now depends on the page content language
  64   instead of the wiki content language
  65 * Jump links will now be usable in css-capable browsers instead of only
  66   in outdated text browsers.
  67 * New common*.css files usable by skins instead of having to copy piles
  68   of generic styles from MonoBook or Vector's css.
  69 * Some deprecated presentational html attributes will now be automatically converted to css.
  70 * (bug 31233) New OutputPage::addJsConfigVars() method to make the output page specific
  71   mw.config map extendable.
  72 * (bug 31297) Add support for namespaces in Special:RecentChanges subpage filter syntax.
  73 * The default user signature now contains a talk link in addition to the user link.
  74
  75 === Bug fixes in 1.19 ===

  78   until the second was introduced in 1.17.
  79 * (bug 25355) Parser generates edit section links for special pages.
  80 * (bug 27894) Move 'editondblclick' event listener down from body to
  81   div#bodyContent.
  82 * (bug 30172) The check for posix_isatty() in maintenance scripts did not detect
  83   when the function exists but is disabled. Introduced
  84   Maintenance::posix_isatty().
  85 * (bug 30264) Changed installer-generated LocalSettings.php to use
  86   require_once() instead require() for included extensions.
  87 * Do not convert text in the user interface language to another script.
  88 * (bug 26283) Previewing user JS/CSS pages didn't load other user JS/CSS pages
  89 * (bug 11374) Improved diff readability for colorblind people.
  90 * (bug 26486) ResourceLoader modules with paths to nonexistent files cause PHP
  91   warnings/notices to be thrown.

  93   used

  95   truncating log comments.

 107 * (bug 31081) $wgEnotifUseJobQ causes many unnecessary jobs to be queued
 108 * (bug 30202) File names are now restricted on upload to 240 bytes, because of
 109   restrictions on some of the database fields.
 110 * Timezones are now recognised in user preferences when offset is different
 111   due to DST

 130 === Languages updated in 1.19 ===

 146
 147 == Compatibility ==
 148
 149 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 150
 151 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 152 support for them is somewhat less mature. There is experimental support for IBM
 153 DB2 and Microsoft SQL Server.
 154
 155 The supported versions are:
 156
 157 * MySQL 4.0 or later
 158 * PostgreSQL 8.3 or later
 159 * SQLite 3
 160 * Oracle 9.0.1 or later
 161
 162 == Upgrading ==
 163
 164 1.19 has several database changes since 1.18, and will not work without schema
 165 updates.
 166
 167 If upgrading from before 1.11, and you are using a wiki as a commons
 168 repository, make sure that it is updated as well. Otherwise, errors may arise
 169 due to database schema changes.
 170
 171 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 172 new database fields are filled with data.
 173
 174 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 175 changes are made, and there is a slightly higher chance that things could
 176 break. Don't forget to always back up your database before upgrading!
 177
 178 See the file UPGRADE for more detailed upgrade instructions.
 179
 180 For notes on 1.15.x and older releases, see HISTORY.
 181
 182 == Online documentation ==
 183
 184 Documentation for both end-users and site administrators is available on
 185 MediaWiki.org, and is covered under the GNU Free Documentation License (except
