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

  57 == Compatibility ==
  58
  59 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
  60 HHVM 3.3.0.
  61
  62 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  63 support for them is somewhat less mature. There is experimental support for
  64 Oracle and Microsoft SQL Server.
  65
  66 The supported versions are:
  67
  68 * MySQL 5.0.2 or later
  69 * PostgreSQL 8.3 or later
  70 * SQLite 3.3.7 or later
  71 * Oracle 9.0.1 or later
  72 * Microsoft SQL Server 2005 (9.00.1399)
  73
  74 == Upgrading ==
  75
  76 1.25 has several database changes since 1.24, and will not work without schema
  77 updates. Note that due to changes to some very large tables like the revision
  78 table, the schema update may take quite long (minutes on a medium sized site,
  79 many hours on a large site).
  80
  81 If upgrading from before 1.11, and you are using a wiki as a commons
  82 repository, make sure that it is updated as well. Otherwise, errors may arise
  83 due to database schema changes.
  84
  85 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  86 new database fields are filled with data.
  87
  88 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  89 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  90 with MediaWiki 1.21.
  91
  92 Don't forget to always back up your database before upgrading!
  93
  94 See the file UPGRADE for more detailed upgrade instructions.
