   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.25 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.25 ===
  12 * $wgPageShowWatchingUsers was removed.
  13 * $wgLocalVirtualHosts has been added to replace $wgConf->localVHosts.
  14 * $wgAntiLockFlags was removed.
  15
  16 === New features in 1.25 ===
  17 * (bug 58139) ResourceLoaderFileModule now supports language fallback
  18   for 'languageScripts'.
  19 * Added a new hook, "ContentAlterParserOutput", to allow extensions to modify the
  20   parser output for a content object before links update.
  21 * (bug 67341) SVG images will no longer be base64-encoded when being embedded
  22   in CSS. This results in slight size increase before gzip compression (due to
  23   percent-encoding), but up to 20% decrease after it.
  24
  25 === Bug fixes in 1.25 ===
  26 * (bug 71003) No additional code will be generated to try to load CSS-embedded
  27   SVG images in Internet Explorer 6 and 7, as they don't support them anyway.
  28 * (bug 67021) On Special:BookSources, corrected validation of ISBNs (both
  29   10- and 13-digit forms) containing "X".
  30
  31 === Action API changes in 1.25 ===
  32 * (bug 65403) XML tag highlighting is now only performed for formats
  33   "xmlfm" and "wddxfm".
  34
  35 === Action API internal changes in 1.25 ===
  36
  37 === Languages updated in 1.25 ===
  38
  39 MediaWiki supports over 350 languages. Many localisations are updated
  40 regularly. Below only new and removed languages are listed, as well as
  41 changes to languages because of Bugzilla reports.
  42
  43 === Other changes in 1.25 ===
  44 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
  45   removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
  46   migration guide for creators and users of custom skins that relied on it.
  47 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
  48 * (bug 56257) Set site logo from mediawiki.skinning.interface module instead of
  49   inline styles in the HTML.
  50 * Removed ApiQueryUsers::getAutoGroups(). (deprecated since 1.20)
  51 * Removed XmlDumpWriter::schemaVersion(). (deprecated since 1.20)
  52 * Removed LogEventsList::getDisplayTitle(). (deprecated since 1.20)
  53 * Removed Preferences::trySetUserEmail(). (deprecated since 1.20)
  54 * Removed mw.user.name() and mw.user.anonymous() methods. (deprecated since 1.20)
  55 * Removed 'ok' and 'err' parameters in the mediawiki.api modules. (deprecated
  56   since 1.20)
  57 * Removed 'async' parameter from the  mw.Api#getCategories() method. (deprecated
  58   since 1.20)
  59 * Removed 'jquery.json' module. (deprecated since 1.24)
  60   Use the 'json' module and global JSON object instead.

  62   Also, the former will now throw an MWException if called with one or more
  63   arguments.
  64 * Removed hitcounters and associated code.
  65
  66 == Compatibility ==
  67
  68 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
  69 HHVM 3.3.0.
  70
  71 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  72 support for them is somewhat less mature. There is experimental support for
  73 Oracle and Microsoft SQL Server.
  74
  75 The supported versions are:
  76
  77 * MySQL 5.0.2 or later
  78 * PostgreSQL 8.3 or later
  79 * SQLite 3.3.7 or later
  80 * Oracle 9.0.1 or later
  81 * Microsoft SQL Server 2005 (9.00.1399)
  82
  83 == Upgrading ==
  84
  85 1.25 has several database changes since 1.24, and will not work without schema
  86 updates. Note that due to changes to some very large tables like the revision
  87 table, the schema update may take quite long (minutes on a medium sized site,
  88 many hours on a large site).
  89
  90 If upgrading from before 1.11, and you are using a wiki as a commons
  91 repository, make sure that it is updated as well. Otherwise, errors may arise
  92 due to database schema changes.
  93
  94 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  95 new database fields are filled with data.
  96
  97 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  98 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  99 with MediaWiki 1.21.
 100
 101 Don't forget to always back up your database before upgrading!
 102
 103 See the file UPGRADE for more detailed upgrade instructions.
