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.

   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 * $wgPasswordSenderName has been deprecated. To set a custom mailer name,
  30   the system message 'emailsender' should be modified (default: "{{SITENAME}}").
  31
  32 === New features in 1.23 ===
  33 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
  34   Compared to the browser cache, caching in Web Storage allows ResourceLoader
  35   to be more granular about evicting stale modules from the cache while
  36   retaining the ability to retrieve multiple modules in a single HTTP request.
  37   This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
  38   true. This feature is currently considered experimental and should only be
  39   enabled with care.
  40 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
  41   and {{REVISIONTIMESTAMP:}} (with friends).
  42 * Add "wgRelevantUserName" to mw.config containing the current
  43   Skin::getRelevantUser value.
  44 * (bug 56033) Add content model to the page information.
  45 * Added Article::MissingArticleConditions hook to give extensions a chance to
  46   hide their (unrelated) log entries.
  47 * Added $wgOpenSearchDefaultLimit defining the default number of entries to show
  48   on action=opensearch API call.
  49 * For namespaces with $wgNamespaceProtection (including the MediaWiki
  50   namespace), the "protect" tab will be shown only if there are restriction
  51   levels available that would restrict editing beyond what
  52   $wgNamespaceProtection already applies. The protection form will offer only
  53   those protection levels.
  54 * Added $wgAPIFormatModules, allowing extensions to add additional output
  55   formatting modules for the API.
  56 * (bug 47812) The MediaWiki:Group-user.{css,js} pages can now be used to add
  57   custom CSS or JavaScript enabled only for registered users.
  58 * (bug 52005) Special pages RecentChanges, RecentChangesLinked and Watchlist
  59   now include a legend describing the symbols used in lists of changes.
  60 * Improved the accessibility of the tabs in Special:Preferences.
  61 * Added ApiBeforeMain hook, roughly equivalent to the BeforeInitialize hook:
  62   it's called after everything is set up but before any major processing
  63   happens.
  64 * The jquery.client module now performs a component-wise version comparison in
  65   its #test method when strings are used in the browser map: version '1.10' is
  66   now correctly considered larger than '1.2'. Using numbers in the version map
  67   is not affected.
  68 * All API modules now support an assert parameter, which can either be
  69   'user' or 'bot'. The API will throw an error if the user is not logged
  70   in (user) or does not have the 'bot' userright (bot). Based off of the
  71   AssertEdit extension by Steve Sanbeg.
  72 * WikitextContent will now render redirects with the expected "redirect"
  73   header, rather than as an ordered list. Code calling Article::viewRedirect
  74   can probably be changed to no longer special-case redirects.
  75
  76 === Bug fixes in 1.23 ===
  77 * (bug 41759) The "updated since last visit" markers (on history pages, recent
  78   changes and watchlist) and the talk page message indicator are now correctly
  79   updated when the user is viewing old revisions of pages, instead of always
  80   acting as if the latest revision was being viewed.
  81 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
  82   when the email address is already confirmed. Also, consistently use
  83   "confirmed", rather than "authenticated", when messaging whether or not the
  84   user has confirmed an email address.
  85 * (bug 56912) Show correct link color on cached result of Special:DeadendPages.
  86 * Classes TitleListDependency and TitleDependency have been removed, as they
  87   have been found unused in core and extensions for a long time.
  88 * (bug 57098) SpecialPasswordReset now obeys returnto parameter
  89 * (bug 37812) ResourceLoader will notice when a module's definition changes and
  90   recompile it accordingly.
  91 * (bug 57201) SpecialRecentChangesFilters hook is now executed for feeds.
  92 * (bug 58640) Fixed a compatibility issue with PCRE 8.34 that caused pages
  93   to appear blank or with missing text.
  94 * (bug 56931) Updated the plural rules to CLDR 24. They are in new format
  95   which is detailed in UTS 35 Rev 33. The PHP parser and evaluator as well as
  96   the JavaScript evaluator were updated to support the new format. Plural rules
  97   for some languages have changed, most notably Russian. Affected software
  98   messages have been updated and marked for review at translatewiki.net.
  99 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
 100   remaining page content.
 101
 102 === Web API changes in 1.23 ===
 103 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
 104   categories.
 105 * action=query&meta=filerepoinfo now returns additional information for each
 106   repo.
 107 * action=parse&prop=languageshtml was deprecated in 1.18 and will be removed in
 108   MediaWiki 1.24.
 109 * action=parse now has disabletoc flag to disable table of contents in output.
 110 * (bug 25702) list=allcategories, list=allimages, list=alllinks, list=allpages,
 111   list=deletedrevs and list=filearchive did not handle case-sensitivity
 112   properly for all parameters.
 113 * ApiQueryBase::titlePartToKey allows an extra parameter that indicates the
 114   namespace in order to properly capitalize the title part.
 115 * (bug 57874) action=feedcontributions no longer has one item more than limit.
 116 * All API modules now support an assert parameter. See the new features section
 117   for more details.
 118
 119 === Languages updated in 1.23 ===
 120
 121 MediaWiki supports over 350 languages. Many localisations are updated
 122 regularly. Below only new and removed languages are listed, as well as
 123 changes to languages because of Bugzilla reports.
 124
 125 * Support was added for Northern Luri (lrc).
 126
 127 === Other changes in 1.23 ===
 128 * The rc_type field in the recentchanges table has been superseded by a new
 129   rc_source field.  The rc_source field is a string representation of the
 130   change type where rc_type was a numeric constant.  This field is not yet
 131   queried but will be in a future point release of 1.22.
 132 ** Utilize update.php to create and populate this new field.  On larger wiki's
 133    which do not wish to update recentchanges table in one large update please
 134    review the sql and comments in maintenance/archives/patch-rc_source.sql.
 135 ** The rc_type field of recentchanges will be deprecated in a future point
 136    release.
 137 * The global variable $wgArticle has been removed after a lengthy deprecation.
 138 * The global functions addButton and insertTags (for mw.toolbar.addButton and
 139   mw.toolbar.insertTags) now emits mw.log.warn when accessed.
 140 * The ExpandTemplates extension has been moved into MediaWiki core.
 141 * (bug 52812) Removed "Disable search suggestions" from Preference.
 142 * (bug 52809) Removed "Disable browser page caching" from Preference.
 143 * Three new modules intended for use by custom skins were added:
 144   'skins.common.elements', 'skins.common.content', and 'skins.common.interface',
 145   representing three levels of standard MediaWiki styling. Previously skin
 146   creators wishing to use them had to refer to the file names of appropriate
 147   files directly, which is now discouraged.
 148 * The modules 'skins.vector' and 'skins.monobook' have been renamed to
 149   'skins.vector.styles' and 'skins.monobook.styles', respectively,
 150   and their definition was changed not to include the common*.css files;
 151   the two skins now load the 'skins.common.interface' module instead.
 152 * A page_links_updated field has been added to the page table.
 153 * SpecialPage::getTitle has been deprecated in favor of
 154   SpecialPage::getPageTitle.

 232 == Compatibility ==
 233
 234 MediaWiki 1.23 requires PHP 5.3.2 or later.
 235
 236 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
 237 support for them is somewhat less mature. There is experimental support for
 238 Oracle.
 239
 240 The supported versions are:
 241
 242 * MySQL 5.0.2 or later
 243 * PostgreSQL 8.3 or later
 244 * SQLite 3.3.7 or later
 245 * Oracle 9.0.1 or later
 246
 247 == Upgrading ==
 248
 249 1.23 has several database changes since 1.22, and will not work without schema
 250 updates. Note that due to changes to some very large tables like the revision
 251 table, the schema update may take quite long (minutes on a medium sized site,
 252 many hours on a large site).
 253
 254 If upgrading from before 1.11, and you are using a wiki as a commons
 255 repository, make sure that it is updated as well. Otherwise, errors may arise
 256 due to database schema changes.
 257
 258 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 259 new database fields are filled with data.
 260
 261 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 262 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 263 with MediaWiki 1.21.
 264
 265 Don't forget to always back up your database before upgrading!
 266
 267 See the file UPGRADE for more detailed upgrade instructions.
 268
 269 For notes on 1.21.x and older releases, see HISTORY.
 270
 271 == Online documentation ==
 272
 273 Documentation for both end-users and site administrators is available on
 274 MediaWiki.org, and is covered under the GNU Free Documentation License (except
 275 for pages that explicitly state that their contents are in the public domain):
 276
 277         https://www.mediawiki.org/wiki/Documentation
 278
 279 == Mailing list ==
 280
 281 A mailing list is available for MediaWiki user support and discussion:
 282
 283         https://lists.wikimedia.org/mailman/listinfo/mediawiki-l
 284
 285 A low-traffic announcements-only list is also available:
 286
 287         https://lists.wikimedia.org/mailman/listinfo/mediawiki-announce
 288
 289 It's highly recommended that you sign up for one of these lists if you're
 290 going to run a public MediaWiki, so you can be notified of security fixes.
 291
 292 == IRC help ==
 293
 294 There's usually someone online in #mediawiki on irc.freenode.net.
