   1 Security reminder: MediaWiki does not require PHP's register_globals. If you
   2 have it on, turn it '''off''' if you can.

   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.23 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.23 ===
  12 * $wgDebugLogGroups values may be set to an associative array with a
  13   'destination' key specifying the log destination. The array may also contain
  14   a 'sample' key with a positive integer value N indicating that the log group
  15   should be sampled by dispatching one in every N messages on average. The
  16   sampling is random.
  17 * In addition to the current exception log format, MediaWiki now serializes
  18   exception metadata to JSON and logs it to the 'exception-json' log group.
  19   This makes MediaWiki easier to integrate with log aggregation and analysis
  20   tools.
  21 * $wgSquidServersNoPurge now supports the use of Classless Inter-Domain
  22   Routing (CIDR) notation to specify contiguous blocks of IPv4 and/or IPv6
  23   addresses that should be trusted to provide X-Forwarded-For headers.
  24 * Preferences 'watchcreations' and 'watchdefault' ("Add pages I create and files
  25   I upload to my watchlist", "Add pages and files I edit to my watchlist") are
  26   now enabled by default.
  27
  28 === New features in 1.23 ===
  29 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
  30   Compared to the browser cache, caching in Web Storage allows ResourceLoader
  31   to be more granular about evicting stale modules from the cache while
  32   retaining the ability to retrieve multiple modules in a single HTTP request.
  33   This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
  34   true. This feature is currently considered experimental and should only be
  35   enabled with care.
  36 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
  37   and {{REVISIONTIMESTAMP:}} (with friends).
  38 * Add "wgRelevantUserName" to mw.config containing the current
  39   Skin::getRelevantUser value.
  40 * (bug 56033) Add content model to the page information.
  41 * Added Article::MissingArticleConditions hook to give extensions a chance to
  42   hide their (unrelated) log entries.
  43 * Added $wgOpenSearchDefaultLimit defining the default number of entries to show
  44   on action=opensearch API call.
  45 * For namespaces with $wgNamespaceProtection (including the MediaWiki
  46   namespace), the "protect" tab will be shown only if there are restriction
  47   levels available that would restrict editing beyond what
  48   $wgNamespaceProtection already applies. The protection form will offer only
  49   those protection levels.
  50 * Added $wgAPIFormatModules, allowing extensions to add additional output
  51   formatting modules for the API.
  52 * (bug 47812) The MediaWiki:Group-user.{css,js} pages can now be used to add
  53   custom CSS or JavaScript enabled only for registered users.
  54 * (bug 52005) Special pages RecentChanges, RecentChangesLinked and Watchlist
  55   now include a legend describing the symbols used in lists of changes.
  56 * Improved the accessibility of the tabs in Special:Preferences.
  57 * Added ApiBeforeMain hook, roughly equivalent to the BeforeInitialize hook:
  58   it's called after everything is set up but before any major processing
  59   happens.
  60
  61 === Bug fixes in 1.23 ===
  62 * (bug 41759) The "updated since last visit" markers (on history pages, recent
  63   changes and watchlist) and the talk page message indicator are now correctly
  64   updated when the user is viewing old revisions of pages, instead of always
  65   acting as if the latest revision was being viewed.
  66 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
  67   when the email address is already confirmed. Also, consistently use
  68   "confirmed", rather than "authenticated", when messaging whether or not the
  69   user has confirmed an email address.
  70 * (bug 56912) Show correct link color on cached result of Special:DeadendPages.
  71 * Classes TitleListDependency and TitleDependency have been removed, as they
  72   have been found unused in core and extensions for a long time.
  73 * (bug 57098) SpecialPasswordReset now obeys returnto parameter
  74 * (bug 37812) ResourceLoader will notice when a module's definition changes and
  75   recompile it accordingly.
  76 * (bug 57201) SpecialRecentChangesFilters hook is now executed for feeds.
  77
  78 === API changes in 1.23 ===
  79 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
  80   categories.
  81 * action=query&meta=filerepoinfo now returns additional information for each
  82   repo.
  83 * EditPage::spamPage() was deprecated since 1.17 and has been removed.
  84 * action=parse&prop=languageshtml was deprecated in 1.18 and will be removed in
  85   MediaWiki 1.24.
  86 * action=parse now has disabletoc flag to disable table of contents in output.
  87 * SpecialRecentChanges::feedSetup() was removed.
  88
  89 === Languages updated in 1.23 ===
  90
  91 MediaWiki supports over 350 languages. Many localisations are updated
  92 regularly. Below only new and removed languages are listed, as well as
  93 changes to languages because of Bugzilla reports.
  94
  95 * Support was added for Northern Luri (lrc)
  96
  97 === Other changes in 1.23 ===
  98 * The rc_type field in the recentchanges table has been superseded by a new
  99   rc_source field.  The rc_source field is a string representation of the
 100   change type where rc_type was a numeric constant.  This field is not yet
 101   queried but will be in a future point release of 1.22.
 102 ** Utilize update.php to create and populate this new field.  On larger wiki's
 103    which do not wish to update recentchanges table in one large update please
 104    review the sql and comments in maintenance/archives/patch-rc_source.sql.
 105 ** The rc_type field of recentchanges will be deprecated in a future point
 106    release.
 107 * The global variable $wgArticle has been removed after a lengthy deprecation.
 108 * The global functions addButton and insertTags (for mw.toolbar.addButton and
 109   mw.toolbar.insertTags) now emits mw.log.warn when accessed.
 110 * User::getPageRenderingHash() was deprecated since 1.17 and has been removed.
 111 * The ExpandTemplates extension has been moved into MediaWiki core.
 112 * (bug 52812) Removed "Disable search suggestions" from Preference.
 113 * (bug 52809) Removed "Disable browser page caching" from Preference.
 114
 115 == Compatibility ==
 116
 117 MediaWiki 1.23 requires PHP 5.3.2 or later.
 118
 119 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 120 support for them is somewhat less mature. There is experimental support for
 121 Oracle.
 122
 123 The supported versions are:
 124
 125 * MySQL 5.0.2 or later
 126 * PostgreSQL 8.3 or later
 127 * SQLite 3.3.7 or later
 128 * Oracle 9.0.1 or later
 129
 130 == Upgrading ==
 131
 132 1.23 has several database changes since 1.22, and will not work without schema
 133 updates. Note that due to changes to some very large tables like the revision
 134 table, the schema update may take quite long (minutes on a medium sized site,
 135 many hours on a large site).
 136
 137 If upgrading from before 1.11, and you are using a wiki as a commons
 138 repository, make sure that it is updated as well. Otherwise, errors may arise
 139 due to database schema changes.
 140
 141 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 142 new database fields are filled with data.
 143
 144 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 145 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 146 with MediaWiki 1.21.
 147
 148 Don't forget to always back up your database before upgrading!
 149
 150 See the file UPGRADE for more detailed upgrade instructions.
 151
 152 For notes on 1.21.x and older releases, see HISTORY.
 153
