   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
  13 === New features in 1.23 ===
  14 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
  15   Compared to the browser cache, caching in Web Storage allows ResourceLoader
  16   to be more granular about evicting stale modules from the cache while
  17   retaining the ability to retrieve multiple modules in a single HTTP request.
  18   This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
  19   true. This feature is currently considered experimental and should only be
  20   enabled with care.
  21 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
  22   and {{REVISIONTIMESTAMP:}} (with friends).
  23
  24 === Bug fixes in 1.23 ===
  25 * (bug 41759) The "updated since last visit" markers (on history pages, recent
  26   changes and watchlist) and the talk page message indicator are now correctly
  27   updated when the user is viewing old revisions of pages, instead of always
  28   acting as if the latest revision was being viewed.
  29
  30 === API changes in 1.23 ===
  31
  32 === Languages updated in 1.23===
  33
  34 MediaWiki supports over 350 languages. Many localisations are updated
  35 regularly. Below only new and removed languages are listed, as well as
  36 changes to languages because of Bugzilla reports.
  37
  38 === Other changes in 1.23 ===
  39 * The global variable $wgArticle has been removed after a lengthy deprecation
  40
  41 == Compatibility ==
  42
  43 MediaWiki 1.23 requires PHP 5.3.2 or later.
  44
  45 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
  46 support for them is somewhat less mature. There is experimental support for
  47 Oracle.
  48
  49 The supported versions are:
  50
  51 * MySQL 5.0.2 or later
  52 * PostgreSQL 8.3 or later
  53 * SQLite 3.3.7 or later
  54 * Oracle 9.0.1 or later
  55
  56 == Upgrading ==
  57
  58 1.23 has several database changes since 1.22, and will not work without schema
  59 updates. Note that due to changes to some very large tables like the revision
  60 table, the schema update may take quite long (minutes on a medium sized site,
  61 many hours on a large site).
  62
  63 If upgrading from before 1.11, and you are using a wiki as a commons
  64 repository, make sure that it is updated as well. Otherwise, errors may arise
  65 due to database schema changes.
  66
  67 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
  68 new database fields are filled with data.
  69
  70 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
  71 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
  72 with MediaWiki 1.21.
  73
  74 Don't forget to always back up your database before upgrading!
  75
  76 See the file UPGRADE for more detailed upgrade instructions.
