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

  53   generating sitemaps

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

  75
  76 === Bug fixes in 1.19 ===

  84   when the function exists but is disabled. Introduced
  85   Maintenance::posix_isatty().

  87   require_once() instead require() for included extensions.
  88 * Do not convert text in the user interface language to another script.
  89 * (bug 26283) Previewing user JS/CSS pages didn't load other user JS/CSS pages
  90 * (bug 11374) Improved diff readability for colorblind people.
  91 * (bug 26486) ResourceLoader modules with paths to nonexistent files cause PHP

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

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