   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 * Changed LoginAuthenticateAudit hook so that it may be called before a
  15   valid user is available.  In those cases, an anonymouse user object
  16   will be supplied
  17 * Removed SkinTemplateSetupPageCss hook; use BeforePageDisplay instead.
  18 * (bug 27132) movefile right granted by default to registered users.
  19 * Default cookie lifetime ($wgCookieExpiration) is increased to 180 days.
  20 * (bug 31204) Removed old user.user_options
  21 * $wgMaxImageArea now applies to jpeg files if they are not scaled with
  22   ImageMagick.
  23 * Introduced $wgQueryPageDefaultLimit (defaults to 50) for the number of
  24   items to show by default on query pages (special pages such as Whatlinkshere).
  25 * (bug 32470) Increase the length of ug_group
  26 * (bug 32239) Removed wgEnableTooltipsAndAccesskeys
  27
  28 === New features in 1.19 ===
  29 * (bug 19838) Possibility to get all interwiki prefixes if the interwiki
  30   cache is used.
  31 * $wgDnsBlacklistUrls now accepts an array with url and key as the
  32   elements to work with DNSBLs that require keys, such as
  33   Project Honeypot.
  34 * (bug 30022) Add support for custom loadScript sources to ResourceLoader.
  35 * (bug 19052) Unicode space separator characters (Zs) now terminates external
  36   links and images links.
  37 * (bug 30160) Add public method to mw.loader to get module names from registry.
  38 * (bug 15558) Parameters to special pages included in wikitext can now be passed
  39   as with templates.
  40 * Installer now issues a warning if mod_security is present.
  41 * (bug 29455) Add support for a filter callback function in jQuery byteLimit
  42   plugin.
  43 * Extensions can now participate in the extraction of titles from url paths
  44 * Added two new GetLocalURL hooks to better serve extensions working on a
  45   limited type of titles.
  46 * Added a --no-updates flag to importDump.php that skips updating the links
  47   tables.
  48 * Most presentational html attributes like valign are now converted to inline
  49   css style rules. These attributes were removed from html5 and so we clean
  50   them up when $wgHtml5 is enabled. This can be disabled using
  51   $wgCleanupPresentationalAttributes.
  52 * Magic words (time and number-formatting ones, plus DIRECTIONMARK, but not
  53   NAMESPACE) now depend on the page content language instead of the site
  54   language. In theory this sets the right magic words in system messages,
  55   although they are not used there.
  56 * (bug 30451) Add page_props to RefreshLinks::deleteLinksFromNonexistent
  57 * (bug 30450) Clear page_props table on page deletion

  60   generating sitemaps

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

  85   real name in some parts of the interface instead of a username.
  86 * (bug 30062) Add $wgDBprefix option to cli installer
  87 * getUserPermissionsErrors and getUserPermissionsErrorsExpensive hooks are now
  88   also called when checking for 'read' permission
  89 * Introduce $wgEnableSearchContributorsByIP which controls whether searching
  90   for an IP address redirects to the contributions list for that IP
  91 * (bug 8859) Database::update should take array of tables too
  92 * (bug 19698) Inverse selection for Special:Contributions
  93 * (bug 24037) Add byte length of revision to Special:Contributions
  94 * (bug 1672) Added $wgDisableUploadScriptChecks to allow uploading of files
  95   containing HTML or JS. DISABLING THESE CHECKS IS VERY DANGEROUS.
  96
  97 === Bug fixes in 1.19 ===
  98 * $wgUploadNavigationUrl should be used for file redlinks if
  99   $wgUploadMissingFileUrl is not set. The first was used for this
 100   until the second was introduced in 1.17.

 201 == Compatibility ==
 202
 203 MediaWiki 1.19 requires PHP 5.2.3. PHP 4 is no longer supported.
 204
 205 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 206 support for them is somewhat less mature. There is experimental support for IBM
 207 DB2 and Microsoft SQL Server.
 208
 209 The supported versions are:
 210
 211 * MySQL 4.0 or later
 212 * PostgreSQL 8.3 or later
 213 * SQLite 3
 214 * Oracle 9.0.1 or later
 215
 216 == Upgrading ==
 217
 218 1.19 has several database changes since 1.18, and will not work without schema
 219 updates.
 220
 221 If upgrading from before 1.11, and you are using a wiki as a commons
 222 repository, make sure that it is updated as well. Otherwise, errors may arise
 223 due to database schema changes.
 224
 225 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 226 new database fields are filled with data.
 227
 228 If you are upgrading from MediaWiki 1.4.x or earlier, some major database
 229 changes are made, and there is a slightly higher chance that things could
 230 break. Don't forget to always back up your database before upgrading!
 231
 232 See the file UPGRADE for more detailed upgrade instructions.
 233
 234 For notes on 1.17.x and older releases, see HISTORY.
