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 === Configuration changes in 1.30 ===
   9 * The "C.UTF-8" locale should be used for $wgShellLocale, if available, to avoid
  10   unexpected behavior when code uses locale-sensitive string comparisons. For
  11   example, the Scribunto extension considers "bar" < "Foo" in most locales
  12   since it ignores case.
  13 * $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
  14   documentation of $wgShellLocale for details.
  15 * $wgShellLocale is now applied for all requests. wfInitShellLocale() is
  16   deprecated and a no-op, as it is no longer needed.
  17 * $wgJobClasses may now specify callback functions as an alternative to plain
  18   class names. This is intended for extensions that want control over the
  19   instantiation of their jobs, to allow for proper dependency injection.
  20 * $wgResourceModules may now specify callback functions as an alternative
  21   to plain class names, using the 'factory' key in the module description
  22   array. This allows dependency injection to be used for ResourceLoader modules.
  23 * $wgExceptionHooks has been removed.
  24 * (T45547) $wgUsePigLatinVariant added (off by default).
  25
  26 === New features in 1.30 ===
  27 * (T37247) Output from Parser::parse() will now be wrapped in a div with
  28   class="mw-parser-output" by default. This may be changed or disabled using
  29   ParserOptions::setWrapOutputClass().
  30 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  31   specific tags to be added by users.
  32 * Added a 'ParserOptionsRegister' hook to allow extensions to register
  33   additional parser options.
  34 * (T45547) Included Pig Latin, a language game in English, as a
  35   LanguageConverter variant.  This allows English-speaking developers
  36   to develop and test LanguageConverter more easily.  Pig Latin can be
  37   enabled by setting $wgUsePigLatinVariant to true.
  38 * Added RecentChangesPurgeRows hook to allow extensions to purge data that
  39   depends on the recentchanges table.
  40
  41 === Languages updated in 1.30 ===
  42
  43 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
  44
  45 === External library changes in 1.30 ===
  46
  47 ==== Upgraded external libraries ====
  48 * mediawiki/mediawiki-codesniffer updated to 0.8.1.
  49

  56
  57 === Bug fixes in 1.30 ===
  58 * (T151633) Ordered list items use now Devanagari digits in Nepalese
  59   (thanks to Sfic)
  60
  61 === Action API changes in 1.30 ===
  62 * (T37247) action=parse output will be wrapped in a div with
  63   class="mw-parser-output" by default. This may be changed or disabled using
  64   the new 'wrapoutputclass' parameter.
  65 * When errorformat is not 'bc', abort reasons from action=login will be
  66   formatted as specified by the error formatter parameters.
  67 * action=compare can now handle arbitrary text, deleted revisions, and
  68   returning users and edit comments.
  69 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
  70   'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
  71   parameters to prop=revisions are deprecated, as are the similarly named
  72   parameters to prop=deletedrevisions, list=allrevisions, and
  73   list=alldeletedrevisions. Use action=compare, action=parse, or
  74   action=expandtemplates instead.
  75
  76 === Action API internal changes in 1.30 ===
  77 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
  78   deprecated. The existing message should be split between "apihelp-*-summary"
  79   and "apihelp-*-extended-description".
  80 * (T123931) Individual values of multi-valued parameters can now be marked as
  81   deprecated.
  82
  83 === Languages updated in 1.30 ===
  84 MediaWiki supports over 350 languages. Many localisations are updated
  85 regularly. Below only new and removed languages are listed, as well as
  86 changes to languages because of Phabricator reports.
  87
  88 * …
  89
  90 ==== Pig Latin added ====
  91 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
  92   for easier variant development and testing. Disabled by default. It can be
  93   enabled by setting $wgUsePigLatinVariant to true.
  94
  95 === Other changes in 1.30 ===
  96 * The use of an associative array for $wgProxyList, where the IP address is in
  97   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
  98   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
  99 * mw.user.bucket (deprecated in 1.23) was removed.
 100 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
 101   deprecated. There are no known callers.
 102 * File::getStreamHeaders() was deprecated.
 103 * MediaHandler::getStreamHeaders() was deprecated.
 104 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
 105   used instead.
 106 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
 107   should be used instead.
 108 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
 109 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
 110   deprecated in 1.24) were removed.
 111 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
 112   BagOStuff::makeGlobalKey() should be used instead.
 113 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
 114   As a result of the new uniform handling, '-{' may need to be escaped
 115   (for example, as '-<nowiki/>{') where it occurs inside template arguments
 116   or wikilinks.
 117 * (T163966) Page moves are now counted as edits for the purposes of
 118   autopromotion, i.e., they increment the user_editcount field in the database.
 119 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
 120   manipulating Special:Log and Special:NewPages lines.
 121 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
 122   PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
 123   hooks have an additional parameter, for manipulating HTML data attributes of
 124   RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
 125   $data['attribs'] subarray.
 126 * (T130632) The OutputPage::enableTOC() method was removed.
 127 * WikiPage::getParserOutput() will now throw an exception if passed
 128   ParserOptions that would pollute the parser cache. Callers should use
 129   WikiPage::makeParserOptions() to create the ParserOptions object and only
 130   change options that affect the parser cache key.
 131 * Article::viewRedirect() is deprecated.
 132 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
 133   callable factory function or a class name.
 134 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
 135   are all deprecated. The main ParserCache instance should be obtained from
 136   MediaWikiServices instead. Access to the underlying BagOStuff is possible
 137   through the new ParserCache::getCacheStorage() method.
 138 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
 139
 140 == Compatibility ==
 141 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
 142 HHVM 3.6.5 or later.
 143
 144 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 145 but support for them is somewhat less mature. There is experimental support for
 146 Oracle and Microsoft SQL Server.
 147
 148 The supported versions are:
 149
 150 * MySQL 5.0.3 or later
 151 * PostgreSQL 8.3 or later
 152 * SQLite 3.3.7 or later
 153 * Oracle 9.0.1 or later
 154 * Microsoft SQL Server 2005 (9.00.1399)
 155
 156 == Upgrading ==
 157 1.30 has several database changes since 1.29, and will not work without schema
 158 updates. Note that due to changes to some very large tables like the revision
 159 table, the schema update may take a long time (minutes on a medium sized site,
 160 many hours on a large site).
 161
 162 Don't forget to always back up your database before upgrading!
 163
 164 See the file UPGRADE for more detailed upgrade instructions, including
 165 important information when upgrading from versions prior to 1.11.
