RELEASE-NOTES-1.26

   1 Security reminder: If you have PHP's register_globals option set, you must
   2 turn it off. MediaWiki will not work with it enabled.

   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 * BREAKING CHANGE (T91240): Language code "bh" is not valid in ISO 639 and
  41   was removed, so it will no longer alias to "bho". If you used "bh" as your
  42   wiki's $wgLanguageCode, you must update your configuration.
  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 * supportsDirectEditing and supportsDirectApiEditing methods added to
  49 ContentHandler, to provide a way for ApiEditPage and EditPage to check
  50 if direct editing of content is allowed. These methods return false,
  51 by default for the ContentHandler base class and true for TextContentHandler
  52 and it's derivative classes (everything in core). For Content types that
  53 do not support direct editing, an alternative mechanism should be provided
  54 for editing, such as action overrides or specific api modules.
  55 * mediaWiki.confirmCloseWindow now returns an object of functions, instead of
  56 one function. The callback can't be called directly any more. The callback function
  57 is replaced with confirmCloseWindow.release().
  58
  59 == Compatibility ==
  60
  61 MediaWiki 1.26 requires PHP 5.3.3 or later. There is experimental support for
  62 HHVM 3.3.0.
  63
  64 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  65 support for them is somewhat less mature. There is experimental support for
  66 Oracle and Microsoft SQL Server.
  67
  68 The supported versions are:
  69
  70 * MySQL 5.0.3 or later
  71 * PostgreSQL 8.3 or later
  72 * SQLite 3.3.7 or later
  73 * Oracle 9.0.1 or later
  74 * Microsoft SQL Server 2005 (9.00.1399)
  75
  76 == Upgrading ==
  77
  78 1.26 has several database changes since 1.25, and will not work without schema
  79 updates. Note that due to changes to some very large tables like the revision
  80 table, the schema update may take quite long (minutes on a medium sized site,
  81 many hours on a large site).
  82
  83 If upgrading from before 1.11, and you are using a wiki as a commons
  84 repository, make sure that it is updated as well. Otherwise, errors may arise
  85 due to database schema changes.
  86
  87 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  88 new database fields are filled with data.
  89
  90 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  91 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  92 with MediaWiki 1.21.
  93
  94 Don't forget to always back up your database before upgrading!
  95
  96 See the file UPGRADE for more detailed upgrade instructions.
