   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 * (bug 96170) Add array support for space-separated list attributes (like
  58   'class') in the Html helper class.
  59 * (bug 26470) Add checkered background image on hover on files pages.
  60 * (bug 30774) mediawiki.html: Add support for numbers and booleans in the
  61   attribute values and element contents.
  62 * Conversion script between Tifinagh and Latin for the Tachelhit language
  63 * (bug 16755) Add options 'noreplace' and 'noerror' to {{DEFAULTSORT:...}}
  64   to stop it from replace an already existing default sort, and suppress error.
  65 * (bug 18578) Rewrote revision delete related messages to allow better
  66   localisation
  67 * (bug 30364) LanguageConverter now depends on the page content language
  68   instead of the wiki content language
  69 * Jump links will now be usable in css-capable browsers instead of only
  70   in outdated text browsers.
  71 * New common*.css files usable by skins instead of having to copy piles
  72   of generic styles from MonoBook or Vector's css.
  73 * Some deprecated presentational html attributes will now be automatically
  74   converted to css.
  75 * (bug 31297) Add support for namespaces in Special:RecentChanges subpage filter
  76   syntax.
  77 * The default user signature now contains a talk link in addition to the user link.

  79

  91   require_once() instead require() for included extensions.

 113 * (bug 30202) File names are now restricted on upload to 240 bytes, because of
 114   restrictions on some of the database fields.

 116   due to DST

 162 == Compatibility ==
 163
 164 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 165
 166 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 167 support for them is somewhat less mature. There is experimental support for IBM
 168 DB2 and Microsoft SQL Server.
 169
 170 The supported versions are:
 171
 172 * MySQL 4.0 or later
 173 * PostgreSQL 8.3 or later
 174 * SQLite 3
 175 * Oracle 9.0.1 or later
 176
 177 == Upgrading ==
 178
 179 1.19 has several database changes since 1.18, and will not work without schema
 180 updates.
 181
 182 If upgrading from before 1.11, and you are using a wiki as a commons
 183 repository, make sure that it is updated as well. Otherwise, errors may arise
 184 due to database schema changes.
 185
 186 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 187 new database fields are filled with data.
 188
 189 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 190 changes are made, and there is a slightly higher chance that things could
 191 break. Don't forget to always back up your database before upgrading!
 192
 193 See the file UPGRADE for more detailed upgrade instructions.
 194
 195 For notes on 1.15.x and older releases, see HISTORY.
 196
 197 == Online documentation ==
