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

   4 == MediaWiki 1.26 ==
   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
  17 ==== External libraries ====
  18
  19 === Bug fixes in 1.26 ===
  20 * (bug 51283) load.php sometimes sends 304 response without full headers
  21
  22 === Action API changes in 1.26 ===
  23 * API action=query&list=tags: The displayname can now be boolean false if the
  24   tag is meant to be hidden from user interfaces.
  25 * action=import no longer allows both the namespace= and rootpage= parameters
  26   to be set. If they are both set, the value of rootpage= will be ignored.
  27 * prop=revision output in enum mode is now sorted by timestamp rather than
  28   revision ID. This usually won't make any difference.
  29
  30 === Action API internal changes in 1.26 ===
  31
  32 === Languages updated in 1.26 ===
  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
  39 === Other changes in 1.26 ===
  40 * ChangeTags::tagDescription() will return false if the interface message
  41   for the tag is disabled.
  42 * Added PageHistoryPager::doBatchLookups hook.
  43 * supportsDirectEditing and supportsDirectApiEditing methods added to
  44 ContentHandler, to provide a way for ApiEditPage and EditPage to check
  45 if direct editing of content is allowed. These methods return false,
  46 by default for the ContentHandler base class and true for TextContentHandler
  47 and it's derivative classes (everything in core). For Content types that
  48 do not support direct editing, an alternative mechanism should be provided
  49 for editing, such as action overrides or specific api modules.
  50
  51 == Compatibility ==
  52
  53 MediaWiki 1.26 requires PHP 5.3.3 or later. There is experimental support for
  54 HHVM 3.3.0.
  55
  56 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  57 support for them is somewhat less mature. There is experimental support for
  58 Oracle and Microsoft SQL Server.
  59
  60 The supported versions are:
  61
  62 * MySQL 5.0.3 or later
  63 * PostgreSQL 8.3 or later
  64 * SQLite 3.3.7 or later
  65 * Oracle 9.0.1 or later
  66 * Microsoft SQL Server 2005 (9.00.1399)
  67
  68 == Upgrading ==
  69
  70 1.26 has several database changes since 1.25, and will not work without schema
  71 updates. Note that due to changes to some very large tables like the revision
  72 table, the schema update may take quite long (minutes on a medium sized site,
  73 many hours on a large site).
  74
  75 If upgrading from before 1.11, and you are using a wiki as a commons
  76 repository, make sure that it is updated as well. Otherwise, errors may arise
  77 due to database schema changes.
  78
  79 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  80 new database fields are filled with data.
  81
  82 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  83 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  84 with MediaWiki 1.21.
  85
  86 Don't forget to always back up your database before upgrading!
  87
  88 See the file UPGRADE for more detailed upgrade instructions.
