   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
  18 === New features in 1.19 ===
  19 * (bug 30497) Add client-nojs and client-js classes on document element
  20   to let styles easily hide or show things based on general JS availability
  21 * (bug 19838) Possibility to get all interwiki prefixes if the interwiki
  22   cache is used.
  23 * $wgDnsBlacklistUrls now accepts an array with url and key as the
  24   elements to work with DNSBLs that require keys, such as
  25   Project Honeypot.
  26 * (bug 30022) Add support for custom loadScript sources to ResourceLoader.
  27 * (bug 19052) Unicode space separator characters (Zs) now terminates external
  28   links and images links.
  29 * (bug 30160) Add public method to mw.loader to get module names from registry.
  30 * (bug 15558) Parameters to special pages included in wikitext can now be passed
  31   as with templates.
  32 * Installer now issues a warning if mod_security is present.
  33 * (bug 29455) Add support for a filter callback function in jQuery byteLimit
  34   plugin.
  35 * Extensions can now participate in the extraction of titles from url paths
  36 * Added two new GetLocalURL hooks to better serve extensions working on a
  37   limited type of titles.
  38 * Added a --no-updates flag to importDump.php that skips updating the links
  39   tables.
  40 * Most presentational html attributes like valign are now converted to inline
  41   css style rules. These attributes were removed from html5 and so we clean
  42   them up when $wgHtml5 is enabled. This can be disabled using
  43   $wgCleanupPresentationalAttributes.
  44 * Magic words (time and number-formatting ones, plus DIRECTIONMARK, but not
  45   NAMESPACE) now depend on the page content language instead of the site
  46   language. In theory this sets the right magic words in system messages,
  47   although they are not used there.
  48 * (bug 30451) Add page_props to RefreshLinks::deleteLinksFromNonexistent
  49 * (bug 30450) Clear page_props table on page deletion
  50 * Hook added to check for exempt from account creation throttle
  51 * (bug 30344) Add configuration variable for setting custom priorities when
  52   generating sitemaps
  53 * (bug 16428) Include permalink in printable version
  54 * (bug 96170) Add array support for space-separated list attributes (like
  55   'class') in the Html helper class.
  56 * (bug 26470) Add checkered background image on hover on files pages.
  57 * (bug 30774) mediawiki.html: Add support for numbers and booleans in the
  58   attribute values and element contents.
  59 * Conversion script between Tifinagh and Latin for the Tachelhit language
  60 * (bug 16755) Add options 'noreplace' and 'noerror' to {{DEFAULTSORT:...}}
  61   to stop it from replace an already existing default sort, and suppress error.
  62 * (bug 30364) LanguageConverter now depends on the page content language
  63   instead of the wiki content language
  64 * (bug 18578) Rewrote revision delete related messages to allow better
  65   localisation
  66
  67 === Bug fixes in 1.19 ===
  68 * $wgUploadNavigationUrl should be used for file redlinks if
  69   $wgUploadMissingFileUrl is not set. The first was used for this
  70   until the second was introduced in 1.17.
  71 * (bug 25355) Parser generates edit section links for special pages.
  72 * (bug 27894) Move 'editondblclick' event listener down from body to
  73   div#bodyContent.
  74 * (bug 30172) The check for posix_isatty() in maintenance scripts did not detect
  75   when the function exists but is disabled. Introduced
  76   Maintenance::posix_isatty().
  77 * (bug 30264) Changed installer-generated LocalSettings.php to use
  78   require_once() instead require() for included extensions.
  79 * Do not convert text in the user interface language to another script.
  80 * (bug 26283) Previewing user JS/CSS pages didn't load other user JS/CSS pages
  81 * (bug 11374) Improved diff readability for colorblind people.
  82 * (bug 26486) ResourceLoader modules with paths to nonexistent files cause PHP
  83   warnings/notices to be thrown.
  84 * (bug 30335) Fix for HTMLForms using GET breaking when non-friendly URLs are
  85   used
  86 * (bug 28649) Avoiding half truncated multi-byte unicode characters when
  87   truncating log comments.
  88 * Show --batch-size option in help of maintenance scripts that support it
  89 * (bug 4381) Magic quotes cleaning was not comprehensive, key strings were not
  90   unescaped
  91 * (bug 30684) Fix bad escaping in mw.message for inexistent messages (i.e. <key>)
  92 * (bug 23057) Importers no longer can 'edit' or 'create' a fully-protected page by
  93   importing a new revision into it
  94 * Allowing moving the associated talk pages of subpages even if the base page
  95   has no subpage.
  96

 102 * siprop=interwikimap and siprop=languages can use silanguagecode to have
 103   a best effort language name translation. Use CLDR extension for best result.
 104 * (bug 30230) action=expandtemplates should not silently override invalid title
 105   inputs.
 106 * (bug 18634) Create API to fetch MediaWiki's language fallback tree structure.

 108   address blocks for list=blocks.
 109 * (bug 30591) Add support to only return keys in ApiAllMessages.
 110
 111 === Languages updated in 1.19 ===
 112
 113 MediaWiki supports over 330 languages. Many localisations are updated
 114 regularly. Below only new and removed languages are listed, as well as
 115 changes to languages because of Bugzilla reports.

 119
 120 === Other changes in 1.19 ===

 123   populateImageSha1.php

 125   real IP address.
 126
 127 == Compatibility ==
 128
 129 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 130
 131 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 132 support for them is somewhat less mature. There is experimental support for IBM
 133 DB2 and Microsoft SQL Server.
 134
 135 The supported versions are:
 136
 137 * MySQL 4.0 or later
 138 * PostgreSQL 8.3 or later
 139 * SQLite 3
 140 * Oracle 9.0.1 or later
 141
 142 == Upgrading ==
 143
 144 1.19 has several database changes since 1.18, and will not work without schema
 145 updates.
 146
 147 If upgrading from before 1.11, and you are using a wiki as a commons
 148 repository, make sure that it is updated as well. Otherwise, errors may arise
 149 due to database schema changes.
 150
 151 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 152 new database fields are filled with data.
 153
 154 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 155 changes are made, and there is a slightly higher chance that things could
 156 break. Don't forget to always back up your database before upgrading!
 157
 158 See the file UPGRADE for more detailed upgrade instructions.
 159
 160 For notes on 1.15.x and older releases, see HISTORY.
 161
 162 == Online documentation ==
 163
 164 Documentation for both end-users and site administrators is available on
 165 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 166 for pages that explicitly state that their contents are in the public domain):

 170 == Mailing list ==
 171
 172 A mailing list is available for MediaWiki user support and discussion:
 173
 174         http://lists.wikimedia.org/mailman/listinfo/mediawiki-l

 180 It's highly recommended that you sign up for one of these lists if you're
 181 going to run a public MediaWiki, so you can be notified of security fixes.
