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 * (T120333) Soft-deprecated the use of PHP extension 'mysql' in favor of 'mysqli'.
  37   This PHP extension was deprecated in PHP 5.5 and removed in PHP 7.0. MediaWiki
  38   auto-selects the 'mysqli' driver since MediaWiki 1.22, except if explicitly
  39   requested through the configuration parameter $wgDBservers.
  40 * $wgOOUIEditPage was removed, as it is now the default. This was documented as a
  41   temporary variable during the migration period.
  42
  43 === New features in 1.30 ===
  44 * (T37247) Output from Parser::parse() will now be wrapped in a div with
  45   class="mw-parser-output" by default. This may be changed or disabled using
  46   ParserOptions::setWrapOutputClass().
  47 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  48   specific tags to be added by users.
  49 * Added a 'ParserOptionsRegister' hook to allow extensions to register
  50   additional parser options.
  51 * (T45547) Included Pig Latin, a language game in English, as a
  52   LanguageConverter variant.  This allows English-speaking developers
  53   to develop and test LanguageConverter more easily.  Pig Latin can be
  54   enabled by setting $wgUsePigLatinVariant to true.
  55 * Added RecentChangesPurgeRows hook to allow extensions to purge data that
  56   depends on the recentchanges table.
  57 * Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
  58 * (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
  59   'watchlistunwatchlinks' preference option is enabled). With JavaScript
  60   enabled, these links toggle so the user can also re-watch pages that have
  61   just been unwatched.
  62 * Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
  63   MediaHandlerFactory for parser tests.
  64
  65 === External library changes in 1.30 ===

  79 * (T151633) Ordered list items use now Devanagari digits in Nepalese
  80   (thanks to Sfic)
  81
  82 === Action API changes in 1.30 ===
  83 * (T37247) action=parse output will be wrapped in a div with
  84   class="mw-parser-output" by default. This may be changed or disabled using
  85   the new 'wrapoutputclass' parameter.
  86 * When errorformat is not 'bc', abort reasons from action=login will be
  87   formatted as specified by the error formatter parameters.
  88 * action=compare can now handle arbitrary text, deleted revisions, and
  89   returning users and edit comments.
  90 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
  91   'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
  92   parameters to prop=revisions are deprecated, as are the similarly named
  93   parameters to prop=deletedrevisions, list=allrevisions, and
  94   list=alldeletedrevisions. Use action=compare, action=parse, or
  95   action=expandtemplates instead.
  96
  97 === Action API internal changes in 1.30 ===
  98 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
  99   deprecated. The existing message should be split between "apihelp-*-summary"
 100   and "apihelp-*-extended-description".
 101 * (T123931) Individual values of multi-valued parameters can now be marked as
 102   deprecated.
 103
 104 === Languages updated in 1.30 ===
 105 MediaWiki supports over 350 languages. Many localisations are updated
 106 regularly. Below only new and removed languages are listed, as well as
 107 changes to languages because of Phabricator reports.
 108
 109 * Added: kbp (Kabɩyɛ / Kabiyè)
 110 * Added: skr (Saraiki, سرائیکی)
 111 * Added: tay (Tayal / Atayal)
 112
 113 ==== Pig Latin added ====
 114 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
 115   for easier variant development and testing. Disabled by default. It can be
 116   enabled by setting $wgUsePigLatinVariant to true.
 117
 118 === Other changes in 1.30 ===
 119 * The use of an associative array for $wgProxyList, where the IP address is in
 120   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
 121   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
 122 * mw.user.bucket (deprecated in 1.23) was removed.
 123 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
 124   deprecated. There are no known callers.
 125 * File::getStreamHeaders() was deprecated.
 126 * MediaHandler::getStreamHeaders() was deprecated.
 127 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
 128   used instead.
 129 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
 130   should be used instead.
 131 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
 132 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
 133   deprecated in 1.24) were removed.
 134 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
 135   BagOStuff::makeGlobalKey() should be used instead.
 136 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
 137   As a result of the new uniform handling, '-{' may need to be escaped
 138   (for example, as '-<nowiki/>{') where it occurs inside template arguments
 139   or wikilinks.
 140 * (T163966) Page moves are now counted as edits for the purposes of
 141   autopromotion, i.e., they increment the user_editcount field in the database.
 142 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
 143   manipulating Special:Log and Special:NewPages lines.
 144 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
 145   PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
 146   hooks have an additional parameter, for manipulating HTML data attributes of
 147   RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
 148   $data['attribs'] subarray.
 149 * (T130632) The OutputPage::enableTOC() method was removed.
 150 * WikiPage::getParserOutput() will now throw an exception if passed
 151   ParserOptions that would pollute the parser cache. Callers should use
 152   WikiPage::makeParserOptions() to create the ParserOptions object and only
 153   change options that affect the parser cache key.
 154 * Article::viewRedirect() is deprecated.
 155 * IP::isValidBlock() was deprecated. Use the equivalent IP::isValidRange().
 156 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
 157   callable factory function or a class name.
 158 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
 159   are all deprecated. The main ParserCache instance should be obtained from
 160   MediaWikiServices instead. Access to the underlying BagOStuff is possible
 161   through the new ParserCache::getCacheStorage() method.
 162 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
 163 * Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),
 164   escapeIdForLink() or escapeIdForExternalInterwiki() instead.
 165 * Title::escapeFragmentForURL() was deprecated, use one of the aforementioned
 166   Sanitizer functions or, if possible, Title::getFragmentForURL().
 167 * Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
 168   nothing and is deprecated.
 169 * mw.util.escapeId() was deprecated, use escapeIdForAttribute() or
 170   escapeIdForLink().
 171 * MagicWord::replaceMultiple() (deprecated in 1.25) was removed.
 172 * WikiImporter now requires the second parameter to be an instance of the Config,
 173   class. Prior to that, the Config parameter was optional (a behavior deprecated in
 174   1.25).
 175 * Removed 'jquery.mwExtension' module. (deprecated since 1.26)
 176 * mediawiki.ui: Deprecate greys, which are not part of WikimediaUI color palette
 177   any more.
 178 * CdbReader, CdbWriter, CdbException classes (deprecated in 1.25) were removed.
 179   The namespaced classes in the Cdb namespace should be used instead.
 180 * IPSet class (deprecated in 1.26) was removed. The namespaced IPSet\IPSet
 181   should be used instead.
 182 * RunningStat class (deprecated in 1.27) was removed. The namespaced
 183   RunningStat\RunningStat should be used instead.
 184 * MWMemcached and MemCachedClientforWiki classes (deprecated in 1.27) were removed.
 185   The MemcachedClient class should be used instead.
 186 * EditPage::isOouiEnabled() is deprecated and will always return true.
 187 * Parser::getRandomString() (deprecated in 1.26) was removed.
 188 * Parser::uniqPrefix() (deprecated in 1.26) was removed.
 189 * Parser::extractTagsAndParams() now only accepts three arguments. The fourth,
 190   $uniq_prefix was deprecated in 1.26 and has now been removed.
 191 * (T172514) The following tables have had their UNIQUE indexes turned into proper
 192   PRIMARY KEYs for increased maintainability: categorylinks, imagelinks, iwlinks,
 193   langlinks, log_search, module_deps, objectcache, pagelinks, query_cache, site_stats,
 194   templatelinks, text, transcache, user_former_groups, user_properties.
 195
 196 == Compatibility ==
 197 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
 198 HHVM 3.6.5 or later.
 199
 200 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 201 but support for them is somewhat less mature. There is experimental support for
 202 Oracle and Microsoft SQL Server.
 203
 204 The supported versions are:
 205
 206 * MySQL 5.5.8 or later
 207 * PostgreSQL 8.3 or later
 208 * SQLite 3.3.7 or later
 209 * Oracle 9.0.1 or later
 210 * Microsoft SQL Server 2005 (9.00.1399)
 211
 212 == Upgrading ==
 213 1.30 has several database changes since 1.29, and will not work without schema
 214 updates. Note that due to changes to some very large tables like the revision
 215 table, the schema update may take a long time (minutes on a medium sized site,
 216 many hours on a large site).
 217
 218 Don't forget to always back up your database before upgrading!
 219
 220 See the file UPGRADE for more detailed upgrade instructions, including
 221 important information when upgrading from versions prior to 1.11.
