RELEASE-NOTES-1.23

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

   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
  25 === New features in 1.23 ===
  26 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
  27   Compared to the browser cache, caching in Web Storage allows ResourceLoader
  28   to be more granular about evicting stale modules from the cache while
  29   retaining the ability to retrieve multiple modules in a single HTTP request.
  30   This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
  31   true. This feature is currently considered experimental and should only be
  32   enabled with care.
  33 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
  34   and {{REVISIONTIMESTAMP:}} (with friends).
  35 * Add "wgRelevantUserName" to mw.config containing the current
  36   Skin::getRelevantUser value.
  37 * (bug 56033) Add content model to the page information.
  38 * Added Article::MissingArticleConditions hook to give extensions a chance to
  39   hide their (unrelated) log entries.
  40 * Added $wgOpenSearchDefaultLimit defining the default number of entries to show
  41   on action=opensearch API call.
  42 * For namespaces with $wgNamespaceProtection (including the MediaWiki
  43   namespace), the "protect" tab will be shown only if there are restriction
  44   levels available that would restrict editing beyond what
  45   $wgNamespaceProtection already applies. The protection form will offer only
  46   those protection levels.
  47 * Added $wgAPIFormatModules, allowing extensions to add additional output
  48   formatting modules for the API.
  49
  50 === Bug fixes in 1.23 ===
  51 * (bug 41759) The "updated since last visit" markers (on history pages, recent
  52   changes and watchlist) and the talk page message indicator are now correctly
  53   updated when the user is viewing old revisions of pages, instead of always
  54   acting as if the latest revision was being viewed.
  55 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
  56   when the email address is already confirmed. Also, consistently use
  57   "confirmed", rather than "authenticated", when messaging whether or not the
  58   user has confirmed an email address.
  59 * (bug 56912) Show correct link color on cached result of Special:DeadendPages.
  60 * Classes TitleListDependency and TitleDependency have been removed, as they
  61   have been found unused in core and extensions for a long time.
  62 * (bug 57098) SpecialPasswordReset now obeys returnto parameter
  63 * (bug 37812) ResourceLoader will notice when a module's definition changes and
  64   recompile it accordingly.
  65
  66 === API changes in 1.23 ===
  67 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
  68   categories.
  69 * action=query&meta=filerepoinfo now returns additional information for each
  70   repo.
  71 * EditPage::spamPage() was deprecated since 1.17 and has been removed.
  72 * action=parse&prop=languageshtml was deprecated in 1.18 and will be removed in
  73   MediaWiki 1.24.
  74
  75 === Languages updated in 1.23===
  76
  77 MediaWiki supports over 350 languages. Many localisations are updated
  78 regularly. Below only new and removed languages are listed, as well as
  79 changes to languages because of Bugzilla reports.
  80
  81 * Support was added for Northern Luri (lrc)
  82
  83 === Other changes in 1.23 ===
  84 * The rc_type field in the recentchanges table has been superseded by a new
  85   rc_source field.  The rc_source field is a string representation of the
  86   change type where rc_type was a numeric constant.  This field is not yet
  87   queried but will be in a future point release of 1.22.
  88 ** Utilize update.php to create and populate this new field.  On larger wiki's
  89    which do not wish to update recentchanges table in one large update please
  90    review the sql and comments in maintenance/archives/patch-rc_source.sql.
  91 ** The rc_type field of recentchanges will be deprecated in a future point
  92    release.
  93 * The global variable $wgArticle has been removed after a lengthy deprecation.
  94 * The global functions addButton and insertTags (for mw.toolbar.addButton and
  95   mw.toolbar.insertTags) now emits mw.log.warn when accessed.
  96 * User::getPageRenderingHash() was deprecated since 1.17 and has been removed.
  97 * The ExpandTemplates extension has been moved into MediaWiki core.
  98 * (bug 52812) Removed "Disable search suggestions" from Preference.
  99
 100 == Compatibility ==
 101
 102 MediaWiki 1.23 requires PHP 5.3.2 or later.
 103
 104 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 105 support for them is somewhat less mature. There is experimental support for
 106 Oracle.
 107
 108 The supported versions are:
 109
 110 * MySQL 5.0.2 or later
 111 * PostgreSQL 8.3 or later
 112 * SQLite 3.3.7 or later
 113 * Oracle 9.0.1 or later
 114
 115 == Upgrading ==
 116
 117 1.23 has several database changes since 1.22, and will not work without schema
 118 updates. Note that due to changes to some very large tables like the revision
 119 table, the schema update may take quite long (minutes on a medium sized site,
 120 many hours on a large site).
 121
 122 If upgrading from before 1.11, and you are using a wiki as a commons
 123 repository, make sure that it is updated as well. Otherwise, errors may arise
 124 due to database schema changes.
 125
 126 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 127 new database fields are filled with data.
 128
 129 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 130 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 131 with MediaWiki 1.21.
 132
 133 Don't forget to always back up your database before upgrading!
 134
 135 See the file UPGRADE for more detailed upgrade instructions.
 136
 137 For notes on 1.21.x and older releases, see HISTORY.
