23 changes to languages because of Bugzilla reports.
24
25 === Other changes in 1.25 ===
26 * The skin autodiscovery mechanism, deprecated in MediaWiki 1.23, has been
27 removed. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery for
28 migration guide for creators and users of custom skins that relied on it.
29 * Javascript variable 'wgFileCanRotate' now only available on Special:Upload.
30
31 == Compatibility ==
32
33 MediaWiki 1.25 requires PHP 5.3.2 or later. There is experimental support for
34 HHVM 3.3.0.
35
36 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
37 support for them is somewhat less mature. There is experimental support for
38 Oracle and Microsoft SQL Server.
39
40 The supported versions are:
41
42 * MySQL 5.0.2 or later
43 * PostgreSQL 8.3 or later
44 * SQLite 3.3.7 or later
45 * Oracle 9.0.1 or later
46 * Microsoft SQL Server 2005 (9.00.1399)
47
48 == Upgrading ==
49
50 1.25 has several database changes since 1.24, and will not work without schema
51 updates. Note that due to changes to some very large tables like the revision
52 table, the schema update may take quite long (minutes on a medium sized site,
53 many hours on a large site).
54
55 If upgrading from before 1.11, and you are using a wiki as a commons
56 repository, make sure that it is updated as well. Otherwise, errors may arise
57 due to database schema changes.
58
59 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
60 new database fields are filled with data.
61
62 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
63 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
64 with MediaWiki 1.21.
65
66 Don't forget to always back up your database before upgrading!
67
68 See the file UPGRADE for more detailed upgrade instructions.
