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 * (T152540) MediaWiki now supports a section ID escaping style that allows to display
  30   non-Latin characters verbatim on many modern browsers. This is controlled by the
  31   new configuration setting, $wgFragmentMode.
  32 * $wgExperimentalHtmlIds is now deprecated and will be removed in a future version,
  33   use $wgFragmentMode to migrate off it to a modern alternative.
  34 * $wgExternalInterwikiFragmentMode was introduced to control how fragments in
  35   sinterwikis going outside of current wiki farm are encoded.
  36
  37 === New features in 1.30 ===
  38 * (T37247) Output from Parser::parse() will now be wrapped in a div with
  39   class="mw-parser-output" by default. This may be changed or disabled using
  40   ParserOptions::setWrapOutputClass().
  41 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  42   specific tags to be added by users.
  43 * Added a 'ParserOptionsRegister' hook to allow extensions to register
  44   additional parser options.
  45 * (T45547) Included Pig Latin, a language game in English, as a
  46   LanguageConverter variant.  This allows English-speaking developers
  47   to develop and test LanguageConverter more easily.  Pig Latin can be
  48   enabled by setting $wgUsePigLatinVariant to true.
  49 * Added RecentChangesPurgeRows hook to allow extensions to purge data that
  50   depends on the recentchanges table.
  51 * Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
  52 * (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
  53   'watchlistunwatchlinks' preference option is enabled). With JavaScript
  54   enabled, these links toggle so the user can also re-watch pages that have
  55   just been unwatched.
  56
  57 === Languages updated in 1.30 ===
  58
  59 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
  60 * Support for skr (Saraiki, سرائیکی) was added.
  61

  76 * (T151633) Ordered list items use now Devanagari digits in Nepalese
  77   (thanks to Sfic)
  78
  79 === Action API changes in 1.30 ===
  80 * (T37247) action=parse output will be wrapped in a div with
  81   class="mw-parser-output" by default. This may be changed or disabled using
  82   the new 'wrapoutputclass' parameter.
  83 * When errorformat is not 'bc', abort reasons from action=login will be
  84   formatted as specified by the error formatter parameters.
  85 * action=compare can now handle arbitrary text, deleted revisions, and
  86   returning users and edit comments.
  87 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
  88   'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
  89   parameters to prop=revisions are deprecated, as are the similarly named
  90   parameters to prop=deletedrevisions, list=allrevisions, and
  91   list=alldeletedrevisions. Use action=compare, action=parse, or
  92   action=expandtemplates instead.
  93
  94 === Action API internal changes in 1.30 ===
  95 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
  96   deprecated. The existing message should be split between "apihelp-*-summary"
  97   and "apihelp-*-extended-description".
  98 * (T123931) Individual values of multi-valued parameters can now be marked as
  99   deprecated.
 100
 101 === Languages updated in 1.30 ===
 102 MediaWiki supports over 350 languages. Many localisations are updated
 103 regularly. Below only new and removed languages are listed, as well as
 104 changes to languages because of Phabricator reports.
 105
 106 * …
 107
 108 ==== Pig Latin added ====
 109 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
 110   for easier variant development and testing. Disabled by default. It can be
 111   enabled by setting $wgUsePigLatinVariant to true.
 112
 113 === Other changes in 1.30 ===
 114 * The use of an associative array for $wgProxyList, where the IP address is in
 115   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
 116   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
 117 * mw.user.bucket (deprecated in 1.23) was removed.
 118 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
 119   deprecated. There are no known callers.
 120 * File::getStreamHeaders() was deprecated.
 121 * MediaHandler::getStreamHeaders() was deprecated.
 122 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
 123   used instead.
 124 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
 125   should be used instead.
 126 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
 127 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
 128   deprecated in 1.24) were removed.
 129 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
 130   BagOStuff::makeGlobalKey() should be used instead.
 131 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
 132   As a result of the new uniform handling, '-{' may need to be escaped
 133   (for example, as '-<nowiki/>{') where it occurs inside template arguments
 134   or wikilinks.
 135 * (T163966) Page moves are now counted as edits for the purposes of
 136   autopromotion, i.e., they increment the user_editcount field in the database.
 137 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
 138   manipulating Special:Log and Special:NewPages lines.
 139 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
 140   PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
 141   hooks have an additional parameter, for manipulating HTML data attributes of
 142   RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
 143   $data['attribs'] subarray.
 144 * (T130632) The OutputPage::enableTOC() method was removed.
 145 * WikiPage::getParserOutput() will now throw an exception if passed
 146   ParserOptions that would pollute the parser cache. Callers should use
 147   WikiPage::makeParserOptions() to create the ParserOptions object and only
 148   change options that affect the parser cache key.
 149 * Article::viewRedirect() is deprecated.
 150 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
 151   callable factory function or a class name.
 152 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
 153   are all deprecated. The main ParserCache instance should be obtained from
 154   MediaWikiServices instead. Access to the underlying BagOStuff is possible
 155   through the new ParserCache::getCacheStorage() method.
 156 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
 157 * Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),
 158   escapeIdForLink() or escapeIdForExternalInterwiki() instead.
 159 * Title::escapeFragmentForURL() was deprecated, use one of the aforementioned
 160   Sanitizer functions or, if possible, Title::getFragmentForURL().
 161 * Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
 162   nothing and is deprecated.
 163 * mw.util.escapeId() was deprecated, use escapeIdForAttribute() or
 164   escapeIdForLink().
 165
 166 == Compatibility ==
 167 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
 168 HHVM 3.6.5 or later.
 169
 170 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 171 but support for them is somewhat less mature. There is experimental support for
 172 Oracle and Microsoft SQL Server.
 173
 174 The supported versions are:
 175
 176 * MySQL 5.5.8 or later
 177 * PostgreSQL 8.3 or later
 178 * SQLite 3.3.7 or later
 179 * Oracle 9.0.1 or later
 180 * Microsoft SQL Server 2005 (9.00.1399)
 181
 182 == Upgrading ==
 183 1.30 has several database changes since 1.29, and will not work without schema
 184 updates. Note that due to changes to some very large tables like the revision
 185 table, the schema update may take a long time (minutes on a medium sized site,
 186 many hours on a large site).
 187
 188 Don't forget to always back up your database before upgrading!
 189
 190 See the file UPGRADE for more detailed upgrade instructions, including
 191 important information when upgrading from versions prior to 1.11.
