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 hook, 'UserIsBot', to aid in determining if a user is a bot.
  23 * Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
  24   interact with API parsing.

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