   8 THIS IS NOT A RELEASE YET

  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 30497) Add client-nojs and client-js classes on document element
  21   to let styles easily hide or show things based on general JS availability
  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
  52 * (bug 30344) Add configuration variable for setting custom priorities when
  53   generating sitemaps
  54 * (bug 16428) Include permalink in printable version
  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
  73 === Bug fixes in 1.19 ===
  74 * $wgUploadNavigationUrl should be used for file redlinks if
  75   $wgUploadMissingFileUrl is not set. The first was used for this
  76   until the second was introduced in 1.17.
  77 * (bug 25355) Parser generates edit section links for special pages.
  78 * (bug 27894) Move 'editondblclick' event listener down from body to
  79   div#bodyContent.
  80 * (bug 30172) The check for posix_isatty() in maintenance scripts did not detect
  81   when the function exists but is disabled. Introduced
  82   Maintenance::posix_isatty().
  83 * (bug 30264) Changed installer-generated LocalSettings.php to use
  84   require_once() instead require() for included extensions.
  85 * Do not convert text in the user interface language to another script.
  86 * (bug 26283) Previewing user JS/CSS pages didn't load other user JS/CSS pages
  87 * (bug 11374) Improved diff readability for colorblind people.
  88 * (bug 26486) ResourceLoader modules with paths to nonexistent files cause PHP
  89   warnings/notices to be thrown.
  90 * (bug 30335) Fix for HTMLForms using GET breaking when non-friendly URLs are
  91   used
  92 * (bug 28649) Avoiding half truncated multi-byte unicode characters when
  93   truncating log comments.
  94 * Show --batch-size option in help of maintenance scripts that support it
  95 * (bug 4381) Magic quotes cleaning was not comprehensive, key strings were not
  96   unescaped
  97 * (bug 30684) Fix bad escaping in mw.message for inexistent messages (i.e. <key>)
  98 * (bug 23057) Importers no longer can 'edit' or 'create' a fully-protected page by

 102 * (bug 30907) Special:Unusedcategories should sort ascendingly.
 103 * (bug 18424) Special:Prefixindex and Special:Allpages paging links are
 104   really small, and somewhat inconsistent with each other.
 105 * Per page edit-notices now work in namespaces without subpages enabled.
 106 * (bug 30245) Use the correct way to construct a log page title
 107 * (bug 31081) $wgEnotifUseJobQ causes many unnecessary jobs to be queued
 108
 109 === API changes in 1.19 ===
 110 * (bug 19838) siprop=interwikimap can now use the interwiki cache.
 111 * (bug 29748) Add API search prefix support.
 112 * (bug 29684) Set forgotten parameter types in ApiQueryIWLinks.
 113 * (bug 29685) do not output NULL parentid with list=deletedrevs&drprop=parentid.
 114 * siprop=interwikimap and siprop=languages can use silanguagecode to have
 115   a best effort language name translation. Use CLDR extension for best result.
 116 * (bug 30230) action=expandtemplates should not silently override invalid title
 117   inputs.

 126 regularly. Below only new and removed languages are listed, as well as
 127 changes to languages because of Bugzilla reports.

 135   populateImageSha1.php

 137   real IP address.
 138
 139 == Compatibility ==
 140
 141 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 142
 143 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 144 support for them is somewhat less mature. There is experimental support for IBM
 145 DB2 and Microsoft SQL Server.
 146
 147 The supported versions are:
 148
 149 * MySQL 4.0 or later
 150 * PostgreSQL 8.3 or later
 151 * SQLite 3
 152 * Oracle 9.0.1 or later
 153
 154 == Upgrading ==
 155
 156 1.19 has several database changes since 1.18, and will not work without schema
 157 updates.
 158
 159 If upgrading from before 1.11, and you are using a wiki as a commons
 160 repository, make sure that it is updated as well. Otherwise, errors may arise
 161 due to database schema changes.
 162
 163 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 164 new database fields are filled with data.
 165
 166 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 167 changes are made, and there is a slightly higher chance that things could
 168 break. Don't forget to always back up your database before upgrading!
 169
 170 See the file UPGRADE for more detailed upgrade instructions.
 171
 172 For notes on 1.15.x and older releases, see HISTORY.
