5
6 THIS IS NOT A RELEASE YET
7
8 MediaWiki 1.26 is an alpha-quality branch and is not recommended for use in
9 production.
10
11 === Configuration changes in 1.26 ===
12
13 === New features in 1.26 ===
14 * Change tags can now be hidden in the interface by disabling the associated
15 "tag-<id>" interface message.
16
17 ==== External libraries ====
18
19 === Bug fixes in 1.26 ===
20
21 === Action API changes in 1.26 ===
22 * API action=query&list=tags: The displayname can now be boolean false if the
23 tag is meant to be hidden from user interfaces.
24
25 === Action API internal changes in 1.26 ===
26
27 === Languages updated in 1.26 ===
28
29 MediaWiki supports over 350 languages. Many localisations are updated
30 regularly. Below only new and removed languages are listed, as well as
31 changes to languages because of Bugzilla reports.
32
33
34 === Other changes in 1.26 ===
35 * ChangeTags::tagDescription() will return false if the interface message
36 for the tag is disabled.
37 * Added PageHistoryPager::doBatchLookups hook.
38 * supportsDirectEditing and supportsDirectApiEditing methods added to
39 ContentHandler, to provide a way for ApiEditPage and EditPage to check
40 if direct editing of content is allowed. These methods return false,
41 by default for the ContentHandler base class and true for TextContentHandler
42 and it's derivative classes (everything in core). For Content types that
43 do not support direct editing, an alternative mechanism should be provided
44 for editing, such as action overrides or specific api modules.
45
46 == Compatibility ==
47
48 MediaWiki 1.26 requires PHP 5.3.3 or later. There is experimental support for
49 HHVM 3.3.0.
50
51 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
52 support for them is somewhat less mature. There is experimental support for
53 Oracle and Microsoft SQL Server.
54
55 The supported versions are:
56
57 * MySQL 5.0.3 or later
58 * PostgreSQL 8.3 or later
59 * SQLite 3.3.7 or later
60 * Oracle 9.0.1 or later
61 * Microsoft SQL Server 2005 (9.00.1399)
62
63 == Upgrading ==
64
65 1.26 has several database changes since 1.25, 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.
