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 * BREAKING CHANGE: $wgHTTPProxy is now *required* for all external requests
  10   made by MediaWiki via a proxy. Relying on the http_proxy environment
  11   variable is no longer supported.
  12 * The load.php entry point now enforces the existing policy of not allowing
  13   access to session data, which includes the session user and the session
  14   user's language. If such access is attempted, an exception will be thrown.
  15 * The number of internal PBKDF2 iterations used to derive the session secret
  16   is configurable via $wgSessionPbkdf2Iterations.
  17 * Upload dialog's file upload log comment can now be configured separately for
  18   local and foreign uploads.
  19 * $wgForeignUploadTargets now defaults to `[ 'local' ]`, where `'local'`
  20   signifies local uploads. A value of `[]` (empty array) now means that
  21   no upload targets are allowed, effectively disabling the upload dialog.
  22 * The deprecated $wgEditEncoding variable has been removed; it was only used
  23   for Esperanto language character conversion. You are now recommended to use
  24   input methods provided by the UniversalLanguageSelector extension.
  25
  26 === New features in 1.28 ===
  27 * User::isBot() method for checking if an account is a bot role account.
  28 * Added a new 'slideshow' mode for galleries.
  29 * Added a new hook, 'UserIsBot', to aid in determining if a user is a bot.
  30 * Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
  31   interact with API parsing.
  32 * Added a new hook, 'UploadVerifyUpload', which can be used to reject a file
  33   upload. Unlike 'UploadVerifyFile' it provides information about upload comment
  34   and the file description page, but does not run for uploads to stash.
  35
  36 === External library changes in 1.28 ===

  39 * Updated es5-shim from v4.1.5 to v4.5.8

  51   interact with ApiParse and ApiExpandTemplates.
  52
  53 === Languages updated in 1.28 ===
  54
  55 MediaWiki supports over 350 languages. Many localisations are updated
  56 regularly. Below only new and removed languages are listed, as well as
  57 changes to languages because of Phabricator reports.

  63
  64 === Other changes in 1.28 ===
  65 * (T128697) Improved handling of large diffs.
  66 * [BREAKING CHANGE] $wgExtendedLoginCookies has been removed.  You can
  67   use or update a custom session provider if needed.
  68 * Deprecated APIEditBeforeSave hook in favor of EditFilterMergedContent.
  69 * The 'UploadVerification' hook is deprecated. Use 'UploadVerifyFile' instead.
  70 * SiteConfiguration::isLocalVHost() was removed (deprecated since 1.25).
  71 * The 'UserLoginComplete' hook has a new parameter to differentiate between actual
  72   login and visiting the login page while already logged in.
  73 * ResourceLoader::makeLoaderURL() was removed (deprecated since 1.24).
  74
  75 == Compatibility ==
  76
  77 MediaWiki 1.28 requires PHP 5.5.9 or later. There is experimental support for
  78 HHVM 3.6.5 or later.
  79
  80 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  81 support for them is somewhat less mature. There is experimental support for
  82 Oracle and Microsoft SQL Server.
  83
  84 The supported versions are:
  85
  86 * MySQL 5.0.3 or later
  87 * PostgreSQL 8.3 or later
  88 * SQLite 3.3.7 or later
  89 * Oracle 9.0.1 or later
  90 * Microsoft SQL Server 2005 (9.00.1399)
  91
  92 == Upgrading ==
  93
  94 1.28 has several database changes since 1.27, and will not work without schema
  95 updates. Note that due to changes to some very large tables like the revision
  96 table, the schema update may take quite long (minutes on a medium sized site,
  97 many hours on a large site).
  98
  99 If upgrading from before 1.11, and you are using a wiki as a commons
 100 repository, make sure that it is updated as well. Otherwise, errors may arise
 101 due to database schema changes.
 102
 103 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 104 new database fields are filled with data.
 105
 106 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 107 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 108 with MediaWiki 1.21.
 109
 110 Don't forget to always back up your database before upgrading!
 111
 112 See the file UPGRADE for more detailed upgrade instructions.
