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 * (bug 54884) action=parse&prop=categories now indicates hidden and missing
32 categories.
33
34 === Languages updated in 1.23===
35
36 MediaWiki supports over 350 languages. Many localisations are updated
37 regularly. Below only new and removed languages are listed, as well as
38 changes to languages because of Bugzilla reports.
39
40 === Other changes in 1.23 ===
41 * The global variable $wgArticle has been removed after a lengthy deprecation
42
43 == Compatibility ==
44
45 MediaWiki 1.23 requires PHP 5.3.2 or later.
46
47 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
48 support for them is somewhat less mature. There is experimental support for
49 Oracle.
50
51 The supported versions are:
52
53 * MySQL 5.0.2 or later
54 * PostgreSQL 8.3 or later
55 * SQLite 3.3.7 or later
56 * Oracle 9.0.1 or later
57
58 == Upgrading ==
59
60 1.23 has several database changes since 1.22, and will not work without schema
61 updates. Note that due to changes to some very large tables like the revision
62 table, the schema update may take quite long (minutes on a medium sized site,
63 many hours on a large site).
64
65 If upgrading from before 1.11, and you are using a wiki as a commons
66 repository, make sure that it is updated as well. Otherwise, errors may arise
67 due to database schema changes.
68
69 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
70 new database fields are filled with data.
71
72 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
73 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
74 with MediaWiki 1.21.
75
76 Don't forget to always back up your database before upgrading!
77
78 See the file UPGRADE for more detailed upgrade instructions.
79
