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 * The deprecated $wgEditEncoding variable has been removed; it was only used
  20   for Esperanto language character conversion. You are now recommended to use
  21   input methods provided by the UniversalLanguageSelector extension.
  22
  23 === New features in 1.28 ===
  24 * User::isBot() method for checking if an account is a bot role account.
  25 * Added a new 'slideshow' mode for galleries.
  26 * Added a new hook, 'UserIsBot', to aid in determining if a user is a bot.
  27 * Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
  28   interact with API parsing.
  29 * Added a new hook, 'UploadVerifyUpload', which can be used to reject a file
  30   upload. Unlike 'UploadVerifyFile' it provides information about upload comment
  31   and the file description page, but does not run for uploads to stash.
  32

  53 regularly. Below only new and removed languages are listed, as well as

  63 * [BREAKING CHANGE] $wgExtendedLoginCookies has been removed.  You can
  64   use or update a custom session provider if needed.
  65 * Deprecated APIEditBeforeSave hook in favor of EditFilterMergedContent.
  66 * The 'UploadVerification' hook is deprecated. Use 'UploadVerifyFile' instead.
  67
  68 == Compatibility ==
  69
  70 MediaWiki 1.28 requires PHP 5.5.9 or later. There is experimental support for
  71 HHVM 3.6.5 or later.
  72
  73 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  74 support for them is somewhat less mature. There is experimental support for
  75 Oracle and Microsoft SQL Server.
  76
  77 The supported versions are:
  78
  79 * MySQL 5.0.3 or later
  80 * PostgreSQL 8.3 or later
  81 * SQLite 3.3.7 or later
  82 * Oracle 9.0.1 or later
  83 * Microsoft SQL Server 2005 (9.00.1399)
  84
  85 == Upgrading ==
  86
  87 1.28 has several database changes since 1.27, and will not work without schema
  88 updates. Note that due to changes to some very large tables like the revision
  89 table, the schema update may take quite long (minutes on a medium sized site,
  90 many hours on a large site).
  91
  92 If upgrading from before 1.11, and you are using a wiki as a commons
  93 repository, make sure that it is updated as well. Otherwise, errors may arise
  94 due to database schema changes.
  95
  96 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  97 new database fields are filled with data.
  98
  99 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 100 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 101 with MediaWiki 1.21.
 102
 103 Don't forget to always back up your database before upgrading!
 104
 105 See the file UPGRADE for more detailed upgrade instructions.
