6 THIS IS NOT A RELEASE YET
8 MediaWiki 1.23 is an alpha-quality branch and is not recommended for use in
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
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
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.
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
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.
39 === Bug fixes in 1.23 ===
40 * (bug 41759) The "updated since last visit" markers (on history pages, recent
41 changes and watchlist) and the talk page message indicator are now correctly
42 updated when the user is viewing old revisions of pages, instead of always
43 acting as if the latest revision was being viewed.
44 * (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
45 when the email address is already confirmed. Also, consistently use
46 "confirmed", rather than "authenticated", when messaging whether or not the
47 user has confirmed an email address.
48 * (bug 19415) action=render no longer shows section edit links.
50 === API changes in 1.23 ===
51 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
54 === Languages updated in 1.23===
56 MediaWiki supports over 350 languages. Many localisations are updated
57 regularly. Below only new and removed languages are listed, as well as
58 changes to languages because of Bugzilla reports.
60 === Other changes in 1.23 ===
61 * The rc_type field in the recentchanges table has been superseded by a new
62 rc_source field. The rc_source field is a string representation of the
63 change type where rc_type was a numeric constant. This field is not yet
64 queried but will be in a future point release of 1.22.
65 ** Utilize update.php to create and populate this new field. On larger wiki's
66 which do not wish to update recentchanges table in one large update please
67 review the sql and comments in maintenance/archives/patch-rc_source.sql.
68 ** The rc_type field of recentchanges will be deprecated in a future point
70 * The global variable $wgArticle has been removed after a lengthy deprecation.
71 * mediawiki.util: mw.util.wikiGetlink has been renamed to getUrl. (The old name
72 still works, but is deprecated.)
76 MediaWiki 1.23 requires PHP 5.3.2 or later.
78 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
79 support for them is somewhat less mature. There is experimental support for
82 The supported versions are:
84 * MySQL 5.0.2 or later
85 * PostgreSQL 8.3 or later
86 * SQLite 3.3.7 or later
87 * Oracle 9.0.1 or later
91 1.23 has several database changes since 1.22, and will not work without schema
92 updates. Note that due to changes to some very large tables like the revision
93 table, the schema update may take quite long (minutes on a medium sized site,
94 many hours on a large site).
96 If upgrading from before 1.11, and you are using a wiki as a commons
97 repository, make sure that it is updated as well. Otherwise, errors may arise
98 due to database schema changes.
100 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
101 new database fields are filled with data.
103 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
104 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
107 Don't forget to always back up your database before upgrading!
109 See the file UPGRADE for more detailed upgrade instructions.
