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.

   4 == MediaWiki 1.23 ==
   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 * $wgLBFactoryConf: Class names have had underscores removed. The configuration
  28   should be updated if LBFactory_Simple or LBFactory_Multi is configured.
  29
  30 === New features in 1.23 ===
  31 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
  32   Compared to the browser cache, caching in Web Storage allows ResourceLoader
  33   to be more granular about evicting stale modules from the cache while
  34   retaining the ability to retrieve multiple modules in a single HTTP request.
  35   This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
  36   true. This feature is currently considered experimental and should only be
  37   enabled with care.
  38 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
  39   and {{REVISIONTIMESTAMP:}} (with friends).
  40 * Add "wgRelevantUserName" to mw.config containing the current
  41   Skin::getRelevantUser value.
  42 * (bug 56033) Add content model to the page information.
  43 * Added Article::MissingArticleConditions hook to give extensions a chance to
  44   hide their (unrelated) log entries.
  45 * Added $wgOpenSearchDefaultLimit defining the default number of entries to show
  46   on action=opensearch API call.
  47 * For namespaces with $wgNamespaceProtection (including the MediaWiki
  48   namespace), the "protect" tab will be shown only if there are restriction
  49   levels available that would restrict editing beyond what
  50   $wgNamespaceProtection already applies. The protection form will offer only
  51   those protection levels.
  52 * Added $wgAPIFormatModules, allowing extensions to add additional output
  53   formatting modules for the API.
  54 * (bug 47812) The MediaWiki:Group-user.{css,js} pages can now be used to add
  55   custom CSS or JavaScript enabled only for registered users.
  56 * (bug 52005) Special pages RecentChanges, RecentChangesLinked and Watchlist
  57   now include a legend describing the symbols used in lists of changes.
  58 * Improved the accessibility of the tabs in Special:Preferences.
  59 * Added ApiBeforeMain hook, roughly equivalent to the BeforeInitialize hook:
  60   it's called after everything is set up but before any major processing
  61   happens.
  62
  63 === Bug fixes in 1.23 ===
  64 * (bug 41759) The "updated since last visit" markers (on history pages, recent
  65   changes and watchlist) and the talk page message indicator are now correctly
  66   updated when the user is viewing old revisions of pages, instead of always
  67   acting as if the latest revision was being viewed.
  68 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
  69   when the email address is already confirmed. Also, consistently use
  70   "confirmed", rather than "authenticated", when messaging whether or not the
  71   user has confirmed an email address.
  72 * (bug 56912) Show correct link color on cached result of Special:DeadendPages.
  73 * Classes TitleListDependency and TitleDependency have been removed, as they
  74   have been found unused in core and extensions for a long time.
  75 * (bug 57098) SpecialPasswordReset now obeys returnto parameter
  76 * (bug 37812) ResourceLoader will notice when a module's definition changes and
  77   recompile it accordingly.
  78 * (bug 57201) SpecialRecentChangesFilters hook is now executed for feeds.
  79
  80 === API changes in 1.23 ===
  81 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
  82   categories.
  83 * action=query&meta=filerepoinfo now returns additional information for each
  84   repo.
  85 * EditPage::spamPage() was deprecated since 1.17 and has been removed.
  86 * action=parse&prop=languageshtml was deprecated in 1.18 and will be removed in
  87   MediaWiki 1.24.
  88 * action=parse now has disabletoc flag to disable table of contents in output.
  89 * SpecialRecentChanges::feedSetup() was removed.
  90 * (bug 25702) list=allcategories, list=allimages, list=alllinks, list=allpages,
  91   list=deletedrevs and list=filearchive did not handle case-sensitivity
  92   properly for all parameters.
  93 * ApiQueryBase::titlePartToKey allows an extra parameter that indicates the
  94   namespace in order to properly capitalize the title part.
  95 * Renamed classes:
  96   - LBFactory_Fake to LBFactoryFake
  97   - LBFactory_Multi to LBFactoryMulti
  98   - LBFactory_Simple to LBFactorySimple
  99   - LBFactory_Single to LBFactorySingle
 100   - LoadBalancer_Single to LoadBalancerSingle
 101   - LoadMonitor_MySQL to LoadMonitorMySQL
 102   - LoadMonitor_Null to LoadMonitorNull
 103 * Removed methods:
 104   - Linker::makeBrokenLink() (deprecated in 1.16)
 105   - Linker::makeBrokenLinkObj() (deprecated in 1.16)
 106   - Linker::makeColouredLinkObj() (deprecated in 1.16)
 107   - Linker::makeSizeLinkObj() (deprecated in 1.17)
 108
 109 === Languages updated in 1.23 ===
 110
 111 MediaWiki supports over 350 languages. Many localisations are updated
 112 regularly. Below only new and removed languages are listed, as well as
 113 changes to languages because of Bugzilla reports.
 114
 115 * Support was added for Northern Luri (lrc)
 116
 117 === Other changes in 1.23 ===
 118 * The rc_type field in the recentchanges table has been superseded by a new
 119   rc_source field.  The rc_source field is a string representation of the
 120   change type where rc_type was a numeric constant.  This field is not yet
 121   queried but will be in a future point release of 1.22.
 122 ** Utilize update.php to create and populate this new field.  On larger wiki's
 123    which do not wish to update recentchanges table in one large update please
 124    review the sql and comments in maintenance/archives/patch-rc_source.sql.
 125 ** The rc_type field of recentchanges will be deprecated in a future point
 126    release.
 127 * The global variable $wgArticle has been removed after a lengthy deprecation.
 128 * The global functions addButton and insertTags (for mw.toolbar.addButton and
 129   mw.toolbar.insertTags) now emits mw.log.warn when accessed.
 130 * User::getPageRenderingHash() was deprecated since 1.17 and has been removed.
 131 * The ExpandTemplates extension has been moved into MediaWiki core.
 132 * (bug 52812) Removed "Disable search suggestions" from Preference.
 133 * (bug 52809) Removed "Disable browser page caching" from Preference.
 134 * Three new modules intended for use by custom skins were added:
 135   'skins.common.elements', 'skins.common.content', and 'skins.common.interface',
 136   representing three levels of standard MediaWiki styling. Previously skin
 137   creators wishing to use them had to refer to the file names of appropriate
 138   files directly, which is now discouraged.
 139 * The modules 'skins.vector' and 'skins.monobook' have been renamed to
 140   'skins.vector.styles' and 'skins.monobook.styles', respectively,
 141   and their definition was changed not to include the common*.css files;
 142   the two skins now load the 'skins.common.interface' module instead.
 143 * A page_links_updated field has been added to the page table.
 144 * SpecialPage::getTitle has been deprecated in favor of
 145   SpecialPage::getPageTitle.
 146
 147 == Compatibility ==
 148
 149 MediaWiki 1.23 requires PHP 5.3.2 or later.
 150
 151 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 152 support for them is somewhat less mature. There is experimental support for
 153 Oracle.
 154
 155 The supported versions are:
 156
 157 * MySQL 5.0.2 or later
 158 * PostgreSQL 8.3 or later
 159 * SQLite 3.3.7 or later
 160 * Oracle 9.0.1 or later
 161
 162 == Upgrading ==
 163
 164 1.23 has several database changes since 1.22, and will not work without schema
 165 updates. Note that due to changes to some very large tables like the revision
 166 table, the schema update may take quite long (minutes on a medium sized site,
 167 many hours on a large site).
 168
 169 If upgrading from before 1.11, and you are using a wiki as a commons
 170 repository, make sure that it is updated as well. Otherwise, errors may arise
 171 due to database schema changes.
 172
 173 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 174 new database fields are filled with data.
 175
 176 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 177 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 178 with MediaWiki 1.21.
 179
 180 Don't forget to always back up your database before upgrading!
 181
 182 See the file UPGRADE for more detailed upgrade instructions.
 183
 184 For notes on 1.21.x and older releases, see HISTORY.
