RELEASE-NOTES-1.23

   1 Security reminder: MediaWiki does not require PHP's register_globals. If you
   2 have it on, turn it '''off''' if you can.

   5
   6 THIS IS NOT A RELEASE YET
   7
   8 MediaWiki 1.23 is an alpha-quality branch and is not recommended for use in
   9 production.
  10
  11 === Configuration changes in 1.23 ===
  12 * $wgDebugLogGroups values may be set to an associative array with a
  13   'destination' key specifying the log destination. The array may also contain
  14   a 'sample' key with a positive integer value N indicating that the log group
  15   should be sampled by dispatching one in every N messages on average. The
  16   sampling is random.
  17 * In addition to the current exception log format, MediaWiki now serializes
  18   exception metadata to JSON and logs it to the 'exception-json' log group.
  19   This makes MediaWiki easier to integrate with log aggregation and analysis
  20   tools.
  21 * $wgSquidServersNoPurge now supports the use of Classless Inter-Domain
  22   Routing (CIDR) notation to specify contiguous blocks of IPv4 and/or IPv6
  23   addresses that should be trusted to provide X-Forwarded-For headers.
  24
  25 === New features in 1.23 ===
  26 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
  27   Compared to the browser cache, caching in Web Storage allows ResourceLoader
  28   to be more granular about evicting stale modules from the cache while
  29   retaining the ability to retrieve multiple modules in a single HTTP request.
  30   This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
  31   true. This feature is currently considered experimental and should only be
  32   enabled with care.
  33 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
  34   and {{REVISIONTIMESTAMP:}} (with friends).
  35 * Add "wgRelevantUserName" to mw.config containing the current
  36   Skin::getRelevantUser value.
  37 * (bug 56033) Add content model to the page information.
  38 * Added Article::MissingArticleConditions hook to give extensions a chance to
  39   hide their (unrelated) log entries.
  40
  41 === Bug fixes in 1.23 ===
  42 * (bug 41759) The "updated since last visit" markers (on history pages, recent
  43   changes and watchlist) and the talk page message indicator are now correctly
  44   updated when the user is viewing old revisions of pages, instead of always
  45   acting as if the latest revision was being viewed.
  46 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
  47   when the email address is already confirmed. Also, consistently use
  48   "confirmed", rather than "authenticated", when messaging whether or not the
  49   user has confirmed an email address.
  50 * (bug 19415) action=render no longer shows section edit links. This affects
  51   behavior of several other features where (bogus) section edit links will
  52   disappear, such as file description pages loaded via $wgUseInstantCommons or
  53   pages transcluded cross-wiki via $wgEnableScaryTranscluding.
  54
  55 === API changes in 1.23 ===
  56 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
  57   categories.
  58
  59 === Languages updated in 1.23===
  60
  61 MediaWiki supports over 350 languages. Many localisations are updated
  62 regularly. Below only new and removed languages are listed, as well as
  63 changes to languages because of Bugzilla reports.
  64
  65 === Other changes in 1.23 ===
  66 * The rc_type field in the recentchanges table has been superseded by a new
  67   rc_source field.  The rc_source field is a string representation of the
  68   change type where rc_type was a numeric constant.  This field is not yet
  69   queried but will be in a future point release of 1.22.
  70 ** Utilize update.php to create and populate this new field.  On larger wiki's
  71    which do not wish to update recentchanges table in one large update please
  72    review the sql and comments in maintenance/archives/patch-rc_source.sql.
  73 ** The rc_type field of recentchanges will be deprecated in a future point
  74    release.
  75 * The global variable $wgArticle has been removed after a lengthy deprecation.
  76
  77 == Compatibility ==
  78
  79 MediaWiki 1.23 requires PHP 5.3.2 or later.
  80
  81 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  82 support for them is somewhat less mature. There is experimental support for
  83 Oracle.
  84
  85 The supported versions are:
  86
  87 * MySQL 5.0.2 or later
  88 * PostgreSQL 8.3 or later
  89 * SQLite 3.3.7 or later
  90 * Oracle 9.0.1 or later
  91
  92 == Upgrading ==
  93
  94 1.23 has several database changes since 1.22, and will not work without schema
  95 updates. Note that due to changes to some very large tables like the revision
  96 table, the schema update may take quite long (minutes on a medium sized site,
  97 many hours on a large site).
  98
  99 If upgrading from before 1.11, and you are using a wiki as a commons
 100 repository, make sure that it is updated as well. Otherwise, errors may arise
 101 due to database schema changes.
 102
 103 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
 104 new database fields are filled with data.
 105
 106 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 107 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 108 with MediaWiki 1.21.
 109
 110 Don't forget to always back up your database before upgrading!
 111
 112 See the file UPGRADE for more detailed upgrade instructions.

 114 For notes on 1.21.x and older releases, see HISTORY.
