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 things use local-sensitive string comparisons. For
  11   example, Scribunto considers "bar" < "Foo" in most locales since it ignores
  12   case.
  13 * $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
  14   documentation of $wgShellLocale for details.
  15 * $wgJobClasses may now specify callback functions
  16   as an alternative to plain class names.
  17   This is intended for extensions that want control
  18   over the instantiation of their jobs,
  19   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 * $wgShellLocale is now applied for all requests. wfInitShellLocale() is
  25   deprecated and a no-op, as it is no longer needed.
  26 * WikiPage::getParserOutput() will now throw an exception if passed
  27   ParserOptions would pollute the parser cache. Callers should use
  28   WikiPage::makeParserOptions() to create the ParserOptions object and only
  29   change options that affect the parser cache key.
  30 * (T45547) $wgUsePigLatinVariant added (off by default).
  31
  32 === New features in 1.30 ===
  33 * (T37247) Output from Parser::parse() will now be wrapped in a div with
  34   class="mw-parser-output" by default. This may be changed or disabled using
  35   ParserOptions::setWrapOutputClass().
  36 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  37   specific tags to be added by users.
  38 * Added a 'ParserOptionsRegister' hook to allow extensions to register
  39   additional parser options.
  40 * (T45547) Included Pig Latin, a language game in English, as a
  41   LanguageConverter variant.  This allows English-speaking developers
  42   to develop and test LanguageConverter more easily.  Pig Latin can be
  43   enabled by setting $wgUsePigLatinVariant to true.
  44
  45 === Languages updated in 1.30 ===
  46
  47 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
  48

  53
  54 ==== New external libraries ====

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