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 * When $wgPingback is true, MediaWiki will periodically ping
  26   https://www.mediawiki.org/beacon with basic information about the local
  27   MediaWiki installation.  This data includes, for example, the type of system,
  28   PHP version, and chosen database backend. This behavior is off by default.
  29
  30 === New features in 1.28 ===
  31 * User::isBot() method for checking if an account is a bot role account.
  32 * Added a new 'slideshow' mode for galleries.
  33 * Added a new hook, 'UserIsBot', to aid in determining if a user is a bot.
  34 * Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
  35   interact with API parsing.
  36 * Added a new hook, 'UploadVerifyUpload', which can be used to reject a file
  37   upload. Unlike 'UploadVerifyFile' it provides information about upload comment
  38   and the file description page, but does not run for uploads to stash.
  39 * (T141604) Extensions can now provide a better error message when their
  40   maintenance scripts are run without the extension being installed.
  41 * (T8948) Numeric sorting in categories is now supported by setting $wgCategoryCollation
  42   to uca-default-u-kn or uca-<langcode>-u-kn. If migrating from another
  43   collation, you will need to run the updateCollation.php maintenance script.
  44

  55
  56 === Action API changes in 1.28 ===
  57 * Added 'maxarticlesize' property to action=query&meta=siteinfo which contains
  58   the value of $wgMaxArticleSize.
  59 * Property 'modulemessages' from action=parse&prop=modules was removed
  60   (deprecated since 1.26).
  61 * The following response properties from action=login, deprecated in 1.27, are
  62   now removed: lgtoken, cookieprefix, sessionid. Clients should handle cookies
  63   to properly manage session state.
  64
  65 === Action API internal changes in 1.28 ===
  66 * Added a new hook, 'ApiMakeParserOptions', to allow extensions to better
  67   interact with ApiParse and ApiExpandTemplates.
  68
  69 === Languages updated in 1.28 ===
  70
  71 MediaWiki supports over 350 languages. Many localisations are updated
  72 regularly. Below only new and removed languages are listed, as well as
  73 changes to languages because of Phabricator reports.
  74

  80

  84   use or update a custom session provider if needed.
  85 * Deprecated APIEditBeforeSave hook in favor of EditFilterMergedContent.
  86 * The 'UploadVerification' hook is deprecated. Use 'UploadVerifyFile' instead.
  87 * SiteConfiguration::isLocalVHost() was removed (deprecated since 1.25).

  89   login and visiting the login page while already logged in.

  91 * $.fn.liveAndTestAtStart was removed (deprecated since 1.24).
  92 * Linker::link() and Linker::linkKnown() were deprecated; please instead use
  93   MediaWiki\Linker\LinkRenderer. In addition, the LinkBegin and LinkEnd hooks
  94   were replaced by HtmlPageLinkRendererBegin and HtmlPageLinkRendererEnd
  95   respectively. See docs/hooks.txt for the specific changes needed for those hooks.
  96 * Aliases for Linker methods, deprecated since 1.21, were removed from Skin:

 105   disabled.
 106 * DifferenceEngine::generateDiffBody() was removed (deprecated since 1.21).
 107 * UploadBase::stashFileGetKey() and UploadBase::stashSession() were deprecated.

 110   favour of CC-0.

 112 == Compatibility ==
 113
 114 MediaWiki 1.28 requires PHP 5.5.9 or later. There is experimental support for
 115 HHVM 3.6.5 or later.
 116
 117 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 118 support for them is somewhat less mature. There is experimental support for
 119 Oracle and Microsoft SQL Server.
 120
 121 The supported versions are:
 122
 123 * MySQL 5.0.3 or later
 124 * PostgreSQL 8.3 or later
 125 * SQLite 3.3.7 or later
 126 * Oracle 9.0.1 or later
 127 * Microsoft SQL Server 2005 (9.00.1399)
 128
 129 == Upgrading ==
 130
 131 1.28 has several database changes since 1.27, and will not work without schema
 132 updates. Note that due to changes to some very large tables like the revision
 133 table, the schema update may take quite long (minutes on a medium sized site,
 134 many hours on a large site).
 135
 136 If upgrading from before 1.11, and you are using a wiki as a commons
 137 repository, make sure that it is updated as well. Otherwise, errors may arise
 138 due to database schema changes.
 139
 140 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 141 new database fields are filled with data.
 142
 143 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 144 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 145 with MediaWiki 1.21.
 146
 147 Don't forget to always back up your database before upgrading!
 148
 149 See the file UPGRADE for more detailed upgrade instructions.
