4 == MediaWiki 1.23 ==
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
18 === New features in 1.23 ===
19 * ResourceLoader can utilize the Web Storage API to cache modules client-side.
20 Compared to the browser cache, caching in Web Storage allows ResourceLoader
21 to be more granular about evicting stale modules from the cache while
22 retaining the ability to retrieve multiple modules in a single HTTP request.
23 This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
24 true. This feature is currently considered experimental and should only be
25 enabled with care.
26 * (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
27 and {{REVISIONTIMESTAMP:}} (with friends).
28
29 === Bug fixes in 1.23 ===
30 * (bug 41759) The "updated since last visit" markers (on history pages, recent
31 changes and watchlist) and the talk page message indicator are now correctly
32 updated when the user is viewing old revisions of pages, instead of always
33 acting as if the latest revision was being viewed.
34
35 === API changes in 1.23 ===
36 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
37 categories.
38
39 === Languages updated in 1.23===
40
41 MediaWiki supports over 350 languages. Many localisations are updated
42 regularly. Below only new and removed languages are listed, as well as
43 changes to languages because of Bugzilla reports.
44
45 === Other changes in 1.23 ===
46 * The global variable $wgArticle has been removed after a lengthy deprecation
47
48 == Compatibility ==
49
50 MediaWiki 1.23 requires PHP 5.3.2 or later.
51
52 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
53 support for them is somewhat less mature. There is experimental support for
54 Oracle.
55
56 The supported versions are:
57
58 * MySQL 5.0.2 or later
59 * PostgreSQL 8.3 or later
60 * SQLite 3.3.7 or later
61 * Oracle 9.0.1 or later
62
63 == Upgrading ==
64
65 1.23 has several database changes since 1.22, and will not work without schema
66 updates. Note that due to changes to some very large tables like the revision
67 table, the schema update may take quite long (minutes on a medium sized site,
68 many hours on a large site).
69
70 If upgrading from before 1.11, and you are using a wiki as a commons
71 repository, make sure that it is updated as well. Otherwise, errors may arise
72 due to database schema changes.
73
74 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
75 new database fields are filled with data.
76
77 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
78 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
79 with MediaWiki 1.21.
80
81 Don't forget to always back up your database before upgrading!
82
83 See the file UPGRADE for more detailed upgrade instructions.
84
85 For notes on 1.21.x and older releases, see HISTORY.
