   1 Security reminder: If you have PHP's register_globals option set, you must

   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.26 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.26 ===
  12
  13 === New features in 1.26 ===
  14 * Change tags can now be hidden in the interface by disabling the associated
  15   "tag-<id>" interface message.
  16 * ':' (colon) is now invalid in usernames for new accounts. Existing accounts
  17   are not affected.
  18
  19 ==== External libraries ====
  20
  21 === Bug fixes in 1.26 ===
  22 * (bug 51283) load.php sometimes sends 304 response without full headers
  23
  24 === Action API changes in 1.26 ===
  25 * API action=query&list=tags: The displayname can now be boolean false if the
  26   tag is meant to be hidden from user interfaces.
  27 * action=import no longer allows both the namespace= and rootpage= parameters
  28   to be set. If they are both set, the value of rootpage= will be ignored.
  29 * prop=revision output in enum mode is now sorted by timestamp rather than
  30   revision ID. This usually won't make any difference.
  31
  32 === Action API internal changes in 1.26 ===
  33
  34 === Languages updated in 1.26 ===
  35
  36 MediaWiki supports over 350 languages. Many localisations are updated
  37 regularly. Below only new and removed languages are listed, as well as
  38 changes to languages because of Bugzilla reports.
  39
  40 * Languages added:
  41 ** dty (डोटेली/Doteli), thanks to translators जनक राज भट्ट, बिप्लब आनन्द,
  42    मेश सिंह बोहरा, and राम प्रसाद जोशी
  43
  44 === Other changes in 1.26 ===
  45 * ChangeTags::tagDescription() will return false if the interface message
  46   for the tag is disabled.
  47 * Added PageHistoryPager::doBatchLookups hook.
  48 * Added ParserCacheSaveComplete to ParserCache
  49 * supportsDirectEditing and supportsDirectApiEditing methods added to
  50 ContentHandler, to provide a way for ApiEditPage and EditPage to check
  51 if direct editing of content is allowed. These methods return false,
  52 by default for the ContentHandler base class and true for TextContentHandler
  53 and it's derivative classes (everything in core). For Content types that
  54 do not support direct editing, an alternative mechanism should be provided
  55 for editing, such as action overrides or specific api modules.
  56 * mediaWiki.confirmCloseWindow now returns an object of functions, instead of
  57 one function. The callback can't be called directly any more. The callback function
  58 is replaced with confirmCloseWindow.release().
  59 * Removed maintenance script deleteImageMemcached.php.
  60
  61 == Compatibility ==
  62
  63 MediaWiki 1.26 requires PHP 5.3.3 or later. There is experimental support for
  64 HHVM 3.3.0.
  65
  66 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  67 support for them is somewhat less mature. There is experimental support for
  68 Oracle and Microsoft SQL Server.
  69
  70 The supported versions are:
  71
  72 * MySQL 5.0.3 or later
  73 * PostgreSQL 8.3 or later
  74 * SQLite 3.3.7 or later
  75 * Oracle 9.0.1 or later
  76 * Microsoft SQL Server 2005 (9.00.1399)
  77
  78 == Upgrading ==
  79
  80 1.26 has several database changes since 1.25, and will not work without schema
  81 updates. Note that due to changes to some very large tables like the revision
  82 table, the schema update may take quite long (minutes on a medium sized site,
  83 many hours on a large site).
  84
  85 If upgrading from before 1.11, and you are using a wiki as a commons
  86 repository, make sure that it is updated as well. Otherwise, errors may arise
  87 due to database schema changes.
  88
  89 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  90 new database fields are filled with data.
  91
  92 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  93 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  94 with MediaWiki 1.21.
  95
  96 Don't forget to always back up your database before upgrading!
  97
  98 See the file UPGRADE for more detailed upgrade instructions.
