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
  45 === Languages updated in 1.30 ===
  46
  47 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
  48
  49 === External library changes in 1.30 ===
  50
  51 ==== Upgraded external libraries ====
  52 * mediawiki/mediawiki-codesniffer updated to 0.8.1.
  53
  54 ==== New external libraries ====
  55 * The class \TestingAccessWrapper has been moved to the external library
  56   wikimedia/testing-access-wrapper and renamed \Wikimedia\TestingAccessWrapper.
  57
  58 ==== Removed and replaced external libraries ====
  59 * …
  60
  61 === Bug fixes in 1.30 ===
  62 * (T151633) Ordered list items use now Devanagari digits in Nepalese
  63   (thanks to Sfic)
  64
  65 === Action API changes in 1.30 ===
  66 * (T37247) action=parse output will be wrapped in a div with
  67   class="mw-parser-output" by default. This may be changed or disabled using
  68   the new 'wrapoutputclass' parameter.
  69 * When errorformat is not 'bc', abort reasons from action=login will be
  70   formatted as specified by the error formatter parameters.
  71 * action=compare can now handle arbitrary text, deleted revisions, and
  72   returning users and edit comments.
  73 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
  74   'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
  75   parameters to prop=revisions are deprecated, as are the similarly named
  76   parameters to prop=deletedrevisions, list=allrevisions, and
  77   list=alldeletedrevisions. Use action=compare, action=parse, or
  78   action=expandtemplates instead.
  79
  80 === Action API internal changes in 1.30 ===
  81 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
  82   deprecated. The existing message should be split between "apihelp-*-summary"
  83   and "apihelp-*-extended-description".
  84 * (T123931) Individual values of multi-valued parameters can now be marked as
  85   deprecated.
  86
  87 === Languages updated in 1.30 ===
  88 MediaWiki supports over 350 languages. Many localisations are updated
  89 regularly. Below only new and removed languages are listed, as well as
  90 changes to languages because of Phabricator reports.
  91
  92 * …
  93
  94 ==== Pig Latin added ====
  95 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
  96   for easier variant development and testing. Disabled by default. It can be
  97   enabled by setting $wgUsePigLatinVariant to true.
  98
  99 === Other changes in 1.30 ===
 100 * The use of an associative array for $wgProxyList, where the IP address is in
 101   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
 102   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
 103 * mw.user.bucket (deprecated in 1.23) was removed.
 104 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
 105   deprecated. There are no known callers.
 106 * File::getStreamHeaders() was deprecated.
 107 * MediaHandler::getStreamHeaders() was deprecated.
 108 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
 109   used instead.
 110 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
 111   should be used instead.
 112 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
 113 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
 114   deprecated in 1.24) were removed.
 115 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
 116   BagOStuff::makeGlobalKey() should be used instead.
 117 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
 118   As a result of the new uniform handling, '-{' may need to be escaped
 119   (for example, as '-<nowiki/>{') where it occurs inside template arguments
 120   or wikilinks.
 121 * (T163966) Page moves are now counted as edits for the purposes of
 122   autopromotion, i.e., they increment the user_editcount field in the database.
 123 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
 124   manipulating Special:Log and Special:NewPages lines.
 125 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
 126   PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
 127   hooks have an additional parameter, for manipulating HTML data attributes of
 128   RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
 129   $data['attribs'] subarray.
 130 * (T130632) The OutputPage::enableTOC() method was removed.
 131 * WikiPage::getParserOutput() will now throw an exception if passed
 132   ParserOptions that would pollute the parser cache. Callers should use
 133   WikiPage::makeParserOptions() to create the ParserOptions object and only
 134   change options that affect the parser cache key.
 135 * Article::viewRedirect() is deprecated.
 136 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
 137   callable factory function or a class name.
 138 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
 139   are all deprecated. The main ParserCache instance should be obtained from
 140   MediaWikiServices instead. Access to the underlying BagOStuff is possible
 141   through the new ParserCache::getCacheStorage() method.
 142 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
 143
 144 == Compatibility ==
 145 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
 146 HHVM 3.6.5 or later.
 147
 148 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 149 but support for them is somewhat less mature. There is experimental support for
 150 Oracle and Microsoft SQL Server.
 151
 152 The supported versions are:
 153
 154 * MySQL 5.5.8 or later
 155 * PostgreSQL 8.3 or later
 156 * SQLite 3.3.7 or later
 157 * Oracle 9.0.1 or later
 158 * Microsoft SQL Server 2005 (9.00.1399)
 159
 160 == Upgrading ==
 161 1.30 has several database changes since 1.29, and will not work without schema
 162 updates. Note that due to changes to some very large tables like the revision
 163 table, the schema update may take a long time (minutes on a medium sized site,
 164 many hours on a large site).
 165
 166 Don't forget to always back up your database before upgrading!
 167
 168 See the file UPGRADE for more detailed upgrade instructions, including
 169 important information when upgrading from versions prior to 1.11.
