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
  38 === Bug fixes in 1.23 ===
  39 * (bug 41759) The "updated since last visit" markers (on history pages, recent
  40   changes and watchlist) and the talk page message indicator are now correctly
  41   updated when the user is viewing old revisions of pages, instead of always
  42   acting as if the latest revision was being viewed.
  43 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
  44   when the email address is already confirmed. Also, consistently use
  45   "confirmed", rather than "authenticated", when messaging whether or not the
  46   user has confirmed an email address.
  47
  48 === API changes in 1.23 ===
  49 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
  50   categories.
  51
  52 === Languages updated in 1.23===
  53
  54 MediaWiki supports over 350 languages. Many localisations are updated
  55 regularly. Below only new and removed languages are listed, as well as
  56 changes to languages because of Bugzilla reports.
  57
  58 === Other changes in 1.23 ===
  59 * The rc_type field in the recentchanges table has been superseded by a new
  60   rc_source field.  The rc_source field is a string representation of the
  61   change type where rc_type was a numeric constant.  This field is not yet
  62   queried but will be in a future point release of 1.22.
  63 ** Utilize update.php to create and populate this new field.  On larger wiki's
  64    which do not wish to update recentchanges table in one large update please
  65    review the sql and comments in maintenance/archives/patch-rc_source.sql.
  66 ** The rc_type field of recentchanges will be deprecated in a future point
  67    release.
  68 * The global variable $wgArticle has been removed after a lengthy deprecation
  69 * mediawiki.util: mw.util.wikiGetlink has been renamed to getUrl. (The old name still
  70   works, but is deprecated.)
  71
  72 == Compatibility ==
  73
  74 MediaWiki 1.23 requires PHP 5.3.2 or later.
  75
  76 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  77 support for them is somewhat less mature. There is experimental support for
  78 Oracle.
  79
  80 The supported versions are:
  81
  82 * MySQL 5.0.2 or later
  83 * PostgreSQL 8.3 or later
  84 * SQLite 3.3.7 or later
  85 * Oracle 9.0.1 or later
  86
  87 == Upgrading ==
  88
  89 1.23 has several database changes since 1.22, and will not work without schema
  90 updates. Note that due to changes to some very large tables like the revision
  91 table, the schema update may take quite long (minutes on a medium sized site,
  92 many hours on a large site).
  93
  94 If upgrading from before 1.11, and you are using a wiki as a commons
  95 repository, make sure that it is updated as well. Otherwise, errors may arise
  96 due to database schema changes.
  97
  98 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  99 new database fields are filled with data.
 100
 101 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
 102 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
 103 with MediaWiki 1.21.
 104
 105 Don't forget to always back up your database before upgrading!
 106
 107 See the file UPGRADE for more detailed upgrade instructions.
