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 * mediawiki.util: mw.util.wikiGetlink has been renamed to getUrl. (The old name still
58 works, but is deprecated.)
59
60 == Compatibility ==
61
62 MediaWiki 1.23 requires PHP 5.3.2 or later.
63
64 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
65 support for them is somewhat less mature. There is experimental support for
66 Oracle.
67
68 The supported versions are:
69
70 * MySQL 5.0.2 or later
71 * PostgreSQL 8.3 or later
72 * SQLite 3.3.7 or later
73 * Oracle 9.0.1 or later
74
75 == Upgrading ==
76
77 1.23 has several database changes since 1.22, and will not work without schema
78 updates. Note that due to changes to some very large tables like the revision
79 table, the schema update may take quite long (minutes on a medium sized site,
80 many hours on a large site).
81
82 If upgrading from before 1.11, and you are using a wiki as a commons
83 repository, make sure that it is updated as well. Otherwise, errors may arise
84 due to database schema changes.
85
86 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
87 new database fields are filled with data.
88
89 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
90 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
91 with MediaWiki 1.21.
92
93 Don't forget to always back up your database before upgrading!
94
95 See the file UPGRADE for more detailed upgrade instructions.
96
97 For notes on 1.21.x and older releases, see HISTORY.
