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 * $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 * Added prop=contributors to fetch the list of contributors to the page.
 119
 120 === Languages updated in 1.23 ===
 121
 122 MediaWiki supports over 350 languages. Many localisations are updated
 123 regularly. Below only new and removed languages are listed, as well as
 124 changes to languages because of Bugzilla reports.
 125
 126 * Support was added for Northern Luri (lrc).
 127
 128 === Other changes in 1.23 ===
 129 * The rc_type field in the recentchanges table has been superseded by a new
 130   rc_source field.  The rc_source field is a string representation of the
 131   change type where rc_type was a numeric constant.  This field is not yet
 132   queried but will be in a future point release of 1.22.
 133 ** Utilize update.php to create and populate this new field.  On larger wiki's
 134    which do not wish to update recentchanges table in one large update please
 135    review the sql and comments in maintenance/archives/patch-rc_source.sql.
 136 ** The rc_type field of recentchanges will be deprecated in a future point
 137    release.
 138 * The global variable $wgArticle has been removed after a lengthy deprecation.
 139 * The global functions addButton and insertTags (for mw.toolbar.addButton and
 140   mw.toolbar.insertTags) now emits mw.log.warn when accessed.
 141 * The ExpandTemplates extension has been moved into MediaWiki core.
 142 * (bug 52812) Removed "Disable search suggestions" from Preference.
 143 * (bug 52809) Removed "Disable browser page caching" from Preference.
 144 * Three new modules intended for use by custom skins were added:
 145   'skins.common.elements', 'skins.common.content', and 'skins.common.interface',
 146   representing three levels of standard MediaWiki styling. Previously skin
 147   creators wishing to use them had to refer to the file names of appropriate
 148   files directly, which is now discouraged.
 149 * The modules 'skins.vector' and 'skins.monobook' have been renamed to
 150   'skins.vector.styles' and 'skins.monobook.styles', respectively,
 151   and their definition was changed not to include the common*.css files;
 152   the two skins now load the 'skins.common.interface' module instead.
 153 * A page_links_updated field has been added to the page table.
 154 * SpecialPage::getTitle has been deprecated in favor of
 155   SpecialPage::getPageTitle.

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