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
  22 === New features in 1.23 ===
  23 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
  24   Compared to the browser cache, caching in Web Storage allows ResourceLoader
  25   to be more granular about evicting stale modules from the cache while
  26   retaining the ability to retrieve multiple modules in a single HTTP request.
  27   This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
  28   true. This feature is currently considered experimental and should only be
  29   enabled with care.
  30 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
  31   and {{REVISIONTIMESTAMP:}} (with friends).
  32 * Add "wgRelevantUserName" to mw.config containing the current
  33   Skin::getRelevantUser value
  34
  35 === Bug fixes in 1.23 ===
  36 * (bug 41759) The "updated since last visit" markers (on history pages, recent
  37   changes and watchlist) and the talk page message indicator are now correctly
  38   updated when the user is viewing old revisions of pages, instead of always
  39   acting as if the latest revision was being viewed.
  40 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
  41   when the email address is already confirmed. Also, consistently use
  42   "confirmed", rather than "authenticated", when messaging whether or not the
  43   user has confirmed an email address.
  44
  45 === API changes in 1.23 ===
  46 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
  47   categories.
  48
  49 === Languages updated in 1.23===
  50
  51 MediaWiki supports over 350 languages. Many localisations are updated
  52 regularly. Below only new and removed languages are listed, as well as
  53 changes to languages because of Bugzilla reports.
  54
  55 === Other changes in 1.23 ===
  56 * The global variable $wgArticle has been removed after a lengthy deprecation
  57
  58 == Compatibility ==
  59
  60 MediaWiki 1.23 requires PHP 5.3.2 or later.
  61
  62 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  63 support for them is somewhat less mature. There is experimental support for
  64 Oracle.
  65
  66 The supported versions are:
  67
  68 * MySQL 5.0.2 or later
  69 * PostgreSQL 8.3 or later
  70 * SQLite 3.3.7 or later
  71 * Oracle 9.0.1 or later
  72
  73 == Upgrading ==
  74
  75 1.23 has several database changes since 1.22, and will not work without schema
  76 updates. Note that due to changes to some very large tables like the revision
  77 table, the schema update may take quite long (minutes on a medium sized site,
  78 many hours on a large site).
  79
  80 If upgrading from before 1.11, and you are using a wiki as a commons
  81 repository, make sure that it is updated as well. Otherwise, errors may arise
  82 due to database schema changes.
  83
  84 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  85 new database fields are filled with data.
  86
  87 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  88 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  89 with MediaWiki 1.21.
  90
  91 Don't forget to always back up your database before upgrading!
  92
  93 See the file UPGRADE for more detailed upgrade instructions.
