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 * Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
  57   MediaHandlerFactory for parser tests.
  58
  59 === Languages updated in 1.30 ===
  60
  61 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
  62 * Support for skr (Saraiki, سرائیکی) was added.

  79   (thanks to Sfic)
  80
  81 === Action API changes in 1.30 ===
  82 * (T37247) action=parse output will be wrapped in a div with
  83   class="mw-parser-output" by default. This may be changed or disabled using
  84   the new 'wrapoutputclass' parameter.
  85 * When errorformat is not 'bc', abort reasons from action=login will be
  86   formatted as specified by the error formatter parameters.
  87 * action=compare can now handle arbitrary text, deleted revisions, and
  88   returning users and edit comments.
  89 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
  90   'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
  91   parameters to prop=revisions are deprecated, as are the similarly named
  92   parameters to prop=deletedrevisions, list=allrevisions, and
  93   list=alldeletedrevisions. Use action=compare, action=parse, or
  94   action=expandtemplates instead.
  95
  96 === Action API internal changes in 1.30 ===
  97 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
  98   deprecated. The existing message should be split between "apihelp-*-summary"
  99   and "apihelp-*-extended-description".
 100 * (T123931) Individual values of multi-valued parameters can now be marked as
 101   deprecated.
 102
 103 === Languages updated in 1.30 ===
 104 MediaWiki supports over 350 languages. Many localisations are updated
 105 regularly. Below only new and removed languages are listed, as well as
 106 changes to languages because of Phabricator reports.
 107
 108 * …
 109
 110 ==== Pig Latin added ====
 111 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
 112   for easier variant development and testing. Disabled by default. It can be
 113   enabled by setting $wgUsePigLatinVariant to true.
 114
 115 === Other changes in 1.30 ===
 116 * The use of an associative array for $wgProxyList, where the IP address is in
 117   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
 118   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
 119 * mw.user.bucket (deprecated in 1.23) was removed.
 120 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
 121   deprecated. There are no known callers.
 122 * File::getStreamHeaders() was deprecated.
 123 * MediaHandler::getStreamHeaders() was deprecated.
 124 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
 125   used instead.
 126 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
 127   should be used instead.
 128 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
 129 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
 130   deprecated in 1.24) were removed.
 131 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
 132   BagOStuff::makeGlobalKey() should be used instead.
 133 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
 134   As a result of the new uniform handling, '-{' may need to be escaped
 135   (for example, as '-<nowiki/>{') where it occurs inside template arguments
 136   or wikilinks.
 137 * (T163966) Page moves are now counted as edits for the purposes of
 138   autopromotion, i.e., they increment the user_editcount field in the database.
 139 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
 140   manipulating Special:Log and Special:NewPages lines.
 141 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
 142   PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
 143   hooks have an additional parameter, for manipulating HTML data attributes of
 144   RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
 145   $data['attribs'] subarray.
 146 * (T130632) The OutputPage::enableTOC() method was removed.
 147 * WikiPage::getParserOutput() will now throw an exception if passed
 148   ParserOptions that would pollute the parser cache. Callers should use
 149   WikiPage::makeParserOptions() to create the ParserOptions object and only
 150   change options that affect the parser cache key.
 151 * Article::viewRedirect() is deprecated.
 152 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
 153   callable factory function or a class name.
 154 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
 155   are all deprecated. The main ParserCache instance should be obtained from
 156   MediaWikiServices instead. Access to the underlying BagOStuff is possible
 157   through the new ParserCache::getCacheStorage() method.
 158 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
 159 * Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),
 160   escapeIdForLink() or escapeIdForExternalInterwiki() instead.
 161 * Title::escapeFragmentForURL() was deprecated, use one of the aforementioned
 162   Sanitizer functions or, if possible, Title::getFragmentForURL().
 163 * Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
 164   nothing and is deprecated.
 165 * mw.util.escapeId() was deprecated, use escapeIdForAttribute() or
 166   escapeIdForLink().
 167 * MagicWord::replaceMultiple() (deprecated in 1.25) was removed.
 168 * WikiImporter now requires the second parameter to be an instance of the Config,
 169   class. Prior to that, the Config parameter was optional (a behavior deprecated in
 170   1.25).
 171 * Removed 'jquery.mwExtension' module. (deprecated since 1.26)
 172 * mediawiki.ui: Deprecate greys, which are not part of WikimediaUI color palette
 173   any more.
 174 * CdbReader, CdbWriter, CdbException classes (deprecated in 1.25) were removed.
 175   The namespaced classes in the Cdb namespace should be used instead.
 176 * IPSet class (deprecated in 1.26) was removed. The namespaced IPSet\IPSet
 177   should be used instead.
 178
 179 == Compatibility ==
 180 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
 181 HHVM 3.6.5 or later.
 182
 183 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 184 but support for them is somewhat less mature. There is experimental support for
 185 Oracle and Microsoft SQL Server.
 186
 187 The supported versions are:
 188
 189 * MySQL 5.5.8 or later
 190 * PostgreSQL 8.3 or later
 191 * SQLite 3.3.7 or later
 192 * Oracle 9.0.1 or later
 193 * Microsoft SQL Server 2005 (9.00.1399)
 194
 195 == Upgrading ==
 196 1.30 has several database changes since 1.29, and will not work without schema
 197 updates. Note that due to changes to some very large tables like the revision
 198 table, the schema update may take a long time (minutes on a medium sized site,
 199 many hours on a large site).
 200
 201 Don't forget to always back up your database before upgrading!
 202
 203 See the file UPGRADE for more detailed upgrade instructions, including
 204 important information when upgrading from versions prior to 1.11.
