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 * (T163562) $wgRangeContributionsCIDRLimit was introduced to control the size
  29   of IP ranges that can be queried at Special:Contributions.
  30 * (T45547) $wgUsePigLatinVariant added (off by default).
  31 * (T152540) MediaWiki now supports a section ID escaping style that allows to display
  32   non-Latin characters verbatim on many modern browsers. This is controlled by the
  33   new configuration setting, $wgFragmentMode.
  34 * $wgExperimentalHtmlIds is now deprecated and will be removed in a future version,
  35   use $wgFragmentMode to migrate off it to a modern alternative.
  36 * $wgExternalInterwikiFragmentMode was introduced to control how fragments in
  37   sinterwikis going outside of current wiki farm are encoded.
  38 * (T120333) Soft-deprecated the use of PHP extension 'mysql' in favor of 'mysqli'.
  39   This PHP extension was deprecated in PHP 5.5 and removed in PHP 7.0. MediaWiki
  40   auto-selects the 'mysqli' driver since MediaWiki 1.22, except if explicitly
  41   requested through the configuration parameter $wgDBservers.
  42 * $wgOOUIEditPage was removed, as it is now the default. This was documented as a
  43   temporary variable during the migration period.
  44
  45 === New features in 1.30 ===
  46 * (T37247) Output from Parser::parse() will now be wrapped in a div with
  47   class="mw-parser-output" by default. This may be changed or disabled using
  48   ParserOptions::setWrapOutputClass().
  49 * (T163562) Added ability to search for contributions within an IP ranges
  50   at Special:Contributions.
  51 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  52   specific tags to be added by users.
  53 * Added a 'ParserOptionsRegister' hook to allow extensions to register
  54   additional parser options.
  55 * (T45547) Included Pig Latin, a language game in English, as a
  56   LanguageConverter variant.  This allows English-speaking developers
  57   to develop and test LanguageConverter more easily.  Pig Latin can be
  58   enabled by setting $wgUsePigLatinVariant to true.
  59 * Added RecentChangesPurgeRows hook to allow extensions to purge data that
  60   depends on the recentchanges table.
  61 * Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
  62 * (T2424) Added direct unwatch links to entries in Special:Watchlist (if the
  63   'watchlistunwatchlinks' preference option is enabled). With JavaScript
  64   enabled, these links toggle so the user can also re-watch pages that have
  65   just been unwatched.
  66 * Added $wgParserTestMediaHandlers, where mock media handlers can be passed to
  67   MediaHandlerFactory for parser tests.
  68 * Edit summaries, block reasons, and other "comments" are now stored in a
  69   separate database table. Use the CommentFormatter class to access them.
  70 ** This is currently gated by $wgCommentTableSchemaMigrationStage. Most wikis
  71    can set this to MIGRATION_NEW and run maintenance/migrateComments.php as
  72    soon as any necessary extensions are updated.
  73 * (T138166) Added ability for users to prohibit other users from sending them
  74   emails with Special:Emailuser. Can be enabled by setting
  75   $wgEnableUserEmailBlacklist to true.
  76 * $wgBrowserBlacklist is deprecated, and changing it will have no effect.
  77

  95 === Action API changes in 1.30 ===
  96 * (T37247) action=parse output will be wrapped in a div with
  97   class="mw-parser-output" by default. This may be changed or disabled using
  98   the new 'wrapoutputclass' parameter.
  99 * When errorformat is not 'bc', abort reasons from action=login will be
 100   formatted as specified by the error formatter parameters.
 101 * action=compare can now handle arbitrary text, deleted revisions, and
 102   returning users and edit comments.
 103 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
 104   'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
 105   parameters to prop=revisions are deprecated, as are the similarly named
 106   parameters to prop=deletedrevisions, list=allrevisions, and
 107   list=alldeletedrevisions. Use action=compare, action=parse, or
 108   action=expandtemplates instead.
 109
 110 === Action API internal changes in 1.30 ===
 111 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
 112   deprecated. The existing message should be split between "apihelp-*-summary"
 113   and "apihelp-*-extended-description".
 114 * (T123931) Individual values of multi-valued parameters can now be marked as
 115   deprecated.
 116

 127 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
 128   for easier variant development and testing. Disabled by default. It can be
 129   enabled by setting $wgUsePigLatinVariant to true.
 130
 131 === Other changes in 1.30 ===
 132 * The use of an associative array for $wgProxyList, where the IP address is in
 133   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
 134   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
 135 * mw.user.bucket (deprecated in 1.23) was removed.
 136 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
 137   deprecated. There are no known callers.

 140 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
 141   used instead.
 142 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
 143   should be used instead.
 144 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
 145 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
 146   deprecated in 1.24) were removed.
 147 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
 148   BagOStuff::makeGlobalKey() should be used instead.
 149 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
 150   As a result of the new uniform handling, '-{' may need to be escaped
 151   (for example, as '-<nowiki/>{') where it occurs inside template arguments
 152   or wikilinks.
 153 * (T163966) Page moves are now counted as edits for the purposes of
 154   autopromotion, i.e., they increment the user_editcount field in the database.
 155 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
 156   manipulating Special:Log and Special:NewPages lines.
 157 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
 158   PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
 159   hooks have an additional parameter, for manipulating HTML data attributes of
 160   RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
 161   $data['attribs'] subarray.
 162 * (T130632) The OutputPage::enableTOC() method was removed.
 163 * WikiPage::getParserOutput() will now throw an exception if passed
 164   ParserOptions that would pollute the parser cache. Callers should use
 165   WikiPage::makeParserOptions() to create the ParserOptions object and only
 166   change options that affect the parser cache key.
 167 * Article::viewRedirect() is deprecated.
 168 * IP::isValidBlock() was deprecated. Use the equivalent IP::isValidRange().
 169 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
 170   callable factory function or a class name.
 171 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
 172   are all deprecated. The main ParserCache instance should be obtained from
 173   MediaWikiServices instead. Access to the underlying BagOStuff is possible
 174   through the new ParserCache::getCacheStorage() method.
 175 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
 176 * Sanitizer::escapeId() was deprecated, use escapeIdForAttribute(),
 177   escapeIdForLink() or escapeIdForExternalInterwiki() instead.
 178 * Title::escapeFragmentForURL() was deprecated, use one of the aforementioned
 179   Sanitizer functions or, if possible, Title::getFragmentForURL().
 180 * Second parameter to Sanitizer::escapeIdReferenceList() ($options) now does
 181   nothing and is deprecated.
 182 * mw.util.escapeId() was deprecated, use escapeIdForAttribute() or
 183   escapeIdForLink().
 184 * MagicWord::replaceMultiple() (deprecated in 1.25) was removed.
 185 * WikiImporter now requires the second parameter to be an instance of the Config,
 186   class. Prior to that, the Config parameter was optional (a behavior deprecated in

 189 * mediawiki.ui: Deprecate greys, which are not part of WikimediaUI color palette
 190   any more.

 194   should be used instead.
 195 * RunningStat class (deprecated in 1.27) was removed. The namespaced
 196   RunningStat\RunningStat should be used instead.
 197 * MWMemcached and MemCachedClientforWiki classes (deprecated in 1.27) were removed.
 198   The MemcachedClient class should be used instead.
 199 * EditPage::isOouiEnabled() is deprecated and will always return true.
 200 * EditPage::getSummaryInput() and ::getSummaryInputOOUI() are deprecated. Please
 201   use ::getSummaryInputWidget() instead.
 202 * EditPage::getCheckboxes() and ::getCheckboxesOOUI() are deprecated. Please
 203   use ::getCheckboxesWidget() instead.
 204 * Parser::getRandomString() (deprecated in 1.26) was removed.
 205 * Parser::uniqPrefix() (deprecated in 1.26) was removed.
 206 * Parser::extractTagsAndParams() now only accepts three arguments. The fourth,
 207   $uniq_prefix was deprecated in 1.26 and has now been removed.
 208 * (T172514) The following tables have had their UNIQUE indexes turned into proper
 209   PRIMARY KEYs for increased maintainability: categorylinks, imagelinks, iwlinks,
 210   langlinks, log_search, module_deps, objectcache, pagelinks, query_cache, site_stats,
 211   templatelinks, text, transcache, user_former_groups, user_properties.
 212 * IDatabase::nextSequenceValue() is no longer needed by any database backends
 213   (formerly it was needed by PostgreSQL and Oracle), and is now deprecated.
 214 * (T146591) The lc_lang_key index on the l10n_cache table has been changed into a
 215   PRIMARY KEY.
 216 * (T157227) bot_password.bp_user, change_tag.ct_log_id, change_tag.ct_rev_id,
 217   page_restrictions.pr_user, tag_summary.ts_log_id, tag_summary.ts_rev_id and

 226
 227 == Compatibility ==
 228 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
 229 HHVM 3.6.5 or later.
 230
 231 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 232 but support for them is somewhat less mature. There is experimental support for
 233 Oracle and Microsoft SQL Server.
 234
 235 The supported versions are:
 236
 237 * MySQL 5.5.8 or later
 238 * PostgreSQL 8.3 or later
 239 * SQLite 3.3.7 or later
 240 * Oracle 9.0.1 or later
 241 * Microsoft SQL Server 2005 (9.00.1399)
 242
 243 == Upgrading ==
 244 1.30 has several database changes since 1.29, and will not work without schema
 245 updates. Note that due to changes to some very large tables like the revision
 246 table, the schema update may take a long time (minutes on a medium sized site,
 247 many hours on a large site).
 248
 249 Don't forget to always back up your database before upgrading!
 250
 251 See the file UPGRADE for more detailed upgrade instructions, including
 252 important information when upgrading from versions prior to 1.11.
