RELEASE-NOTES-1.28

   1 == MediaWiki 1.28 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.28 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === Configuration changes in 1.28 ===
   9 * The load.php entry point now enforces the existing policy of not allowing
  10   access to session data, which includes the session user and the session
  11   user's language. If such access is attempted, an exception will be thrown.
  12 * The number of internal PBKDF2 iterations used to derive the session secret
  13   is configurable via $wgSessionPbkdf2Iterations.
  14 * Upload dialog's file upload log comment can now be configured separately for
  15   local and foreign uploads.
  16 * $wgForeignUploadTargets now defaults to `[ 'local' ]`, where `'local'`
  17   signifies local uploads. A value of `[]` (empty array) now means that
  18   no upload targets are allowed, effectively disabling the upload dialog.
  19
  20 === New features in 1.28 ===
  21 * User::isBot() method for checking if an account is a bot role account.
  22 * Added a new 'slider' mode for galleries.
  23 * Added a new hook, 'UserIsBot', to aid in determining if a user is a bot.
  24 * Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
  25   interact with API parsing.
  26 * Added a new hook, 'UploadVerifyUpload', which can be used to reject a file
  27   upload. Unlike 'UploadVerifyFile' it provides information about upload comment
  28   and the file description page, but does not run for uploads to stash.
  29

  47 === Languages updated in 1.28 ===
  48
  49 MediaWiki supports over 350 languages. Many localisations are updated
  50 regularly. Below only new and removed languages are listed, as well as
  51 changes to languages because of Phabricator reports.
  52

  56 === Other changes in 1.28 ===
  57 * (T128697) Improved handling of large diffs.
  58 * [BREAKING CHANGE] $wgExtendedLoginCookies has been removed.  You can
  59   use or update a custom session provider if needed.
  60 * Deprecated APIEditBeforeSave hook in favor of EditFilterMergedContent.
  61 * The 'UploadVerification' hook is deprecated. Use 'UploadVerifyFile' instead.
  62
  63 == Compatibility ==
  64
  65 MediaWiki 1.28 requires PHP 5.5.9 or later. There is experimental support for
  66 HHVM 3.6.5 or later.
  67
  68 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  69 support for them is somewhat less mature. There is experimental support for
  70 Oracle and Microsoft SQL Server.
  71
  72 The supported versions are:
  73
  74 * MySQL 5.0.3 or later
  75 * PostgreSQL 8.3 or later
  76 * SQLite 3.3.7 or later
  77 * Oracle 9.0.1 or later
  78 * Microsoft SQL Server 2005 (9.00.1399)
  79
  80 == Upgrading ==
  81
  82 1.28 has several database changes since 1.27, and will not work without schema
  83 updates. Note that due to changes to some very large tables like the revision
  84 table, the schema update may take quite long (minutes on a medium sized site,
  85 many hours on a large site).
  86
  87 If upgrading from before 1.11, and you are using a wiki as a commons
  88 repository, make sure that it is updated as well. Otherwise, errors may arise
  89 due to database schema changes.
  90
  91 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  92 new database fields are filled with data.
  93
  94 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  95 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  96 with MediaWiki 1.21.
  97
  98 Don't forget to always back up your database before upgrading!
  99
 100 See the file UPGRADE for more detailed upgrade instructions.
