RELEASE-NOTES-1.30

   1 == MediaWiki 1.30 ==
   2
   3 THIS IS NOT A RELEASE YET
   4
   5 MediaWiki 1.30 is an alpha-quality branch and is not recommended for use in
   6 production.
   7
   8 === MySQL version requirement in 1.30 ===
   9 As of 1.30, MediaWiki now requires MySQL 5.5.8 or higher (see Compatibility
  10 section).
  11
  12 === Configuration changes in 1.30 ===
  13 * The "C.UTF-8" locale should be used for $wgShellLocale, if available, to avoid
  14   unexpected behavior when code uses locale-sensitive string comparisons. For
  15   example, the Scribunto extension considers "bar" < "Foo" in most locales
  16   since it ignores case.
  17 * $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
  18   documentation of $wgShellLocale for details.
  19 * $wgShellLocale is now applied for all requests. wfInitShellLocale() is
  20   deprecated and a no-op, as it is no longer needed.
  21 * $wgJobClasses may now specify callback functions as an alternative to plain
  22   class names. This is intended for extensions that want control over the
  23   instantiation of their jobs, to allow for proper dependency injection.
  24 * $wgResourceModules may now specify callback functions as an alternative
  25   to plain class names, using the 'factory' key in the module description
  26   array. This allows dependency injection to be used for ResourceLoader modules.
  27 * $wgExceptionHooks has been removed.
  28 * (T45547) $wgUsePigLatinVariant added (off by default).
  29
  30 === New features in 1.30 ===
  31 * (T37247) Output from Parser::parse() will now be wrapped in a div with
  32   class="mw-parser-output" by default. This may be changed or disabled using
  33   ParserOptions::setWrapOutputClass().
  34 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  35   specific tags to be added by users.
  36 * Added a 'ParserOptionsRegister' hook to allow extensions to register
  37   additional parser options.
  38 * (T45547) Included Pig Latin, a language game in English, as a
  39   LanguageConverter variant.  This allows English-speaking developers
  40   to develop and test LanguageConverter more easily.  Pig Latin can be
  41   enabled by setting $wgUsePigLatinVariant to true.
  42 * Added RecentChangesPurgeRows hook to allow extensions to purge data that
  43   depends on the recentchanges table.
  44 * Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
  45
  46 === Languages updated in 1.30 ===
  47
  48 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
  49
  50 === External library changes in 1.30 ===
  51
  52 ==== Upgraded external libraries ====

  55
  56 ==== New external libraries ====

  58   wikimedia/testing-access-wrapper and renamed \Wikimedia\TestingAccessWrapper.
  59
  60 ==== Removed and replaced external libraries ====
  61 * …
  62
  63 === Bug fixes in 1.30 ===
  64 * (T151633) Ordered list items use now Devanagari digits in Nepalese
  65   (thanks to Sfic)
  66
  67 === Action API changes in 1.30 ===
  68 * (T37247) action=parse output will be wrapped in a div with
  69   class="mw-parser-output" by default. This may be changed or disabled using
  70   the new 'wrapoutputclass' parameter.
  71 * When errorformat is not 'bc', abort reasons from action=login will be
  72   formatted as specified by the error formatter parameters.
  73 * action=compare can now handle arbitrary text, deleted revisions, and
  74   returning users and edit comments.
  75 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
  76   'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
  77   parameters to prop=revisions are deprecated, as are the similarly named
  78   parameters to prop=deletedrevisions, list=allrevisions, and
  79   list=alldeletedrevisions. Use action=compare, action=parse, or
  80   action=expandtemplates instead.
  81
  82 === Action API internal changes in 1.30 ===
  83 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
  84   deprecated. The existing message should be split between "apihelp-*-summary"
  85   and "apihelp-*-extended-description".
  86 * (T123931) Individual values of multi-valued parameters can now be marked as
  87   deprecated.
  88
  89 === Languages updated in 1.30 ===
  90 MediaWiki supports over 350 languages. Many localisations are updated
  91 regularly. Below only new and removed languages are listed, as well as
  92 changes to languages because of Phabricator reports.
  93
  94 * …
  95
  96 ==== Pig Latin added ====
  97 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
  98   for easier variant development and testing. Disabled by default. It can be
  99   enabled by setting $wgUsePigLatinVariant to true.
 100
 101 === Other changes in 1.30 ===
 102 * The use of an associative array for $wgProxyList, where the IP address is in
 103   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
 104   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
 105 * mw.user.bucket (deprecated in 1.23) was removed.
 106 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
 107   deprecated. There are no known callers.
 108 * File::getStreamHeaders() was deprecated.
 109 * MediaHandler::getStreamHeaders() was deprecated.
 110 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
 111   used instead.
 112 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
 113   should be used instead.
 114 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
 115 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
 116   deprecated in 1.24) were removed.
 117 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
 118   BagOStuff::makeGlobalKey() should be used instead.
 119 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
 120   As a result of the new uniform handling, '-{' may need to be escaped
 121   (for example, as '-<nowiki/>{') where it occurs inside template arguments
 122   or wikilinks.
 123 * (T163966) Page moves are now counted as edits for the purposes of
 124   autopromotion, i.e., they increment the user_editcount field in the database.
 125 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
 126   manipulating Special:Log and Special:NewPages lines.
 127 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
 128   PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
 129   hooks have an additional parameter, for manipulating HTML data attributes of
 130   RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
 131   $data['attribs'] subarray.
 132 * (T130632) The OutputPage::enableTOC() method was removed.
 133 * WikiPage::getParserOutput() will now throw an exception if passed
 134   ParserOptions that would pollute the parser cache. Callers should use
 135   WikiPage::makeParserOptions() to create the ParserOptions object and only
 136   change options that affect the parser cache key.
 137 * Article::viewRedirect() is deprecated.
 138 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
 139   callable factory function or a class name.
 140 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
 141   are all deprecated. The main ParserCache instance should be obtained from
 142   MediaWikiServices instead. Access to the underlying BagOStuff is possible
 143   through the new ParserCache::getCacheStorage() method.
 144 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
 145
 146 == Compatibility ==
 147 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
 148 HHVM 3.6.5 or later.
 149
 150 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 151 but support for them is somewhat less mature. There is experimental support for
 152 Oracle and Microsoft SQL Server.
 153
 154 The supported versions are:
 155
 156 * MySQL 5.5.8 or later
 157 * PostgreSQL 8.3 or later
 158 * SQLite 3.3.7 or later
 159 * Oracle 9.0.1 or later
 160 * Microsoft SQL Server 2005 (9.00.1399)
 161
 162 == Upgrading ==
 163 1.30 has several database changes since 1.29, and will not work without schema
 164 updates. Note that due to changes to some very large tables like the revision
 165 table, the schema update may take a long time (minutes on a medium sized site,
 166 many hours on a large site).
 167
 168 Don't forget to always back up your database before upgrading!
 169
 170 See the file UPGRADE for more detailed upgrade instructions, including
 171 important information when upgrading from versions prior to 1.11.
