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
  31 === New features in 1.30 ===
  32 * (T37247) Output from Parser::parse() will now be wrapped in a div with
  33   class="mw-parser-output" by default. This may be changed or disabled using
  34   ParserOptions::setWrapOutputClass().
  35 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  36   specific tags to be added by users.
  37 * File storage backends that supports headers (eg. Swift) now store an
  38   X-Content-Dimensions header for originals that contain the media's dimensions
  39   as page ranges keyed by dimensions.
  40 * Added a 'ParserOptionsRegister' hook to allow extensions to register
  41   additional parser options.
  42
  43 === Languages updated in 1.30 ===
  44
  45 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
  46

  58
  59 === Bug fixes in 1.30 ===
  60 * (T151633) Ordered list items use now Devanagari digits in Nepalese
  61   (thanks to Sfic)
  62
  63 === Action API changes in 1.30 ===
  64 * (T37247) action=parse output will be wrapped in a div with
  65   class="mw-parser-output" by default. This may be changed or disabled using
  66   the new 'wrapoutputclass' parameter.
  67 * When errorformat is not 'bc', abort reasons from action=login will be
  68   formatted as specified by the error formatter parameters.
  69 * action=compare can now handle arbitrary text, deleted revisions, and
  70   returning users and edit comments.
  71
  72 === Action API internal changes in 1.30 ===
  73 * …
  74
  75 === Languages updated in 1.30 ===
  76 MediaWiki supports over 350 languages. Many localisations are updated
  77 regularly. Below only new and removed languages are listed, as well as
  78 changes to languages because of Phabricator reports.
  79
  80 * …
  81
  82 === Other changes in 1.30 ===
  83 * The use of an associative array for $wgProxyList, where the IP address is in
  84   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
  85   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
  86 * mw.user.bucket (deprecated in 1.23) was removed.
  87 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
  88   deprecated. There are no known callers.
  89 * File::getStreamHeaders() was deprecated.
  90 * MediaHandler::getStreamHeaders() was deprecated.
  91 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
  92 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
  93   deprecated in 1.24) were removed.
  94 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
  95   BagOStuff::makeGlobalKey() should be used instead.
  96 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
  97   As a result of the new uniform handling, '-{' may need to be escaped
  98   (for example, as '-<nowiki/>{') where it occurs inside template arguments
  99   or wikilinks.
 100
 101 == Compatibility ==
 102 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
 103 HHVM 3.6.5 or later.
 104
 105 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
 106 but support for them is somewhat less mature. There is experimental support for
 107 Oracle and Microsoft SQL Server.
 108
 109 The supported versions are:
 110
 111 * MySQL 5.0.3 or later
 112 * PostgreSQL 8.3 or later
 113 * SQLite 3.3.7 or later
 114 * Oracle 9.0.1 or later
 115 * Microsoft SQL Server 2005 (9.00.1399)
 116
 117 == Upgrading ==
 118 1.30 has several database changes since 1.29, and will not work without schema
 119 updates. Note that due to changes to some very large tables like the revision
 120 table, the schema update may take quite long (minutes on a medium sized site,
 121 many hours on a large site).
 122
 123 Don't forget to always back up your database before upgrading!
 124
 125 See the file UPGRADE for more detailed upgrade instructions, including
 126 important information when upgrading from versions prior to 1.11.
