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
  25 === New features in 1.30 ===
  26 * (T37247) Output from Parser::parse() will now be wrapped in a div with
  27   class="mw-parser-output" by default. This may be changed or disabled using
  28   ParserOptions::setWrapOutputClass().
  29 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
  30   specific tags to be added by users.
  31 * File storage backends that supports headers (eg. Swift) now store an
  32   X-Content-Dimensions header for originals that contain the media's dimensions
  33   as page ranges keyed by dimensions.
  34

  47 === Bug fixes in 1.30 ===
  48 * (T151633) Ordered list items use now Devanagari digits in Nepalese
  49   (thanks to Sfic)
  50
  51 === Action API changes in 1.30 ===
  52 * (T37247) action=parse output will be wrapped in a div with
  53   class="mw-parser-output" by default. This may be changed or disabled using
  54   the new 'wrapoutputclass' parameter.
  55 * When errorformat is not 'bc', abort reasons from action=login will be
  56   formatted as specified by the error formatter parameters.
  57
  58 === Action API internal changes in 1.30 ===
  59 * …
  60
  61 === Languages updated in 1.30 ===
  62 MediaWiki supports over 350 languages. Many localisations are updated
  63 regularly. Below only new and removed languages are listed, as well as
  64 changes to languages because of Phabricator reports.
  65
  66 * …
  67
  68 === Other changes in 1.30 ===
  69 * The use of an associative array for $wgProxyList, where the IP address is in
  70   the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
  71   Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
  72 * mw.user.bucket (deprecated in 1.23) was removed.
  73 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
  74   deprecated. There are no known callers.
  75 * File::getStreamHeaders() was deprecated.
  76 * MediaHandler::getStreamHeaders() was deprecated.
  77 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
  78 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
  79   deprecated in 1.24) were removed.
  80 * wfMemcKey() and wfGlobalCacheKey() were deprecated. ObjectCache::makeKey() and
  81   ObjectCache::makeGlobalKey() should be used instead.
  82
  83 == Compatibility ==

  85 HHVM 3.6.5 or later.
  86

  88 but support for them is somewhat less mature. There is experimental support for
  89 Oracle and Microsoft SQL Server.
  90
  91 The supported versions are:
  92
  93 * MySQL 5.0.3 or later
  94 * PostgreSQL 8.3 or later

  97 * Microsoft SQL Server 2005 (9.00.1399)
  98
  99 == Upgrading ==
 100 1.30 has several database changes since 1.29, and will not work without schema
 101 updates. Note that due to changes to some very large tables like the revision
 102 table, the schema update may take quite long (minutes on a medium sized site,
 103 many hours on a large site).
 104
 105 Don't forget to always back up your database before upgrading!
 106
 107 See the file UPGRADE for more detailed upgrade instructions, including
 108 important information when upgrading from versions prior to 1.11.
