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 * ':' (colon) is now invalid in usernames for new accounts. Existing accounts
17 are not affected.
18
19 ==== External libraries ====
20
21 === Bug fixes in 1.26 ===
22 * (bug 51283) load.php sometimes sends 304 response without full headers
23
24 === Action API changes in 1.26 ===
25 * API action=query&list=tags: The displayname can now be boolean false if the
26 tag is meant to be hidden from user interfaces.
27 * action=import no longer allows both the namespace= and rootpage= parameters
28 to be set. If they are both set, the value of rootpage= will be ignored.
29 * prop=revision output in enum mode is now sorted by timestamp rather than
30 revision ID. This usually won't make any difference.
31
32 === Action API internal changes in 1.26 ===
33
34 === Languages updated in 1.26 ===
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
41 === Other changes in 1.26 ===
42 * ChangeTags::tagDescription() will return false if the interface message
43 for the tag is disabled.
44 * Added PageHistoryPager::doBatchLookups hook.
45 * supportsDirectEditing and supportsDirectApiEditing methods added to
46 ContentHandler, to provide a way for ApiEditPage and EditPage to check
47 if direct editing of content is allowed. These methods return false,
48 by default for the ContentHandler base class and true for TextContentHandler
49 and it's derivative classes (everything in core). For Content types that
50 do not support direct editing, an alternative mechanism should be provided
51 for editing, such as action overrides or specific api modules.
52 * mediaWiki.confirmCloseWindow now returns an object of functions, instead of
53 one function. The callback can't be called directly any more. The callback function
54 is replaced with confirmCloseWindow.release().
55 * Removed maintenance script deleteImageMemcached.php.
56
57 == Compatibility ==
58
59 MediaWiki 1.26 requires PHP 5.3.3 or later. There is experimental support for
60 HHVM 3.3.0.
61
62 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
63 support for them is somewhat less mature. There is experimental support for
64 Oracle and Microsoft SQL Server.
65
66 The supported versions are:
67
68 * MySQL 5.0.3 or later
69 * PostgreSQL 8.3 or later
70 * SQLite 3.3.7 or later
71 * Oracle 9.0.1 or later
72 * Microsoft SQL Server 2005 (9.00.1399)
73
74 == Upgrading ==
75
76 1.26 has several database changes since 1.25, and will not work without schema
77 updates. Note that due to changes to some very large tables like the revision
78 table, the schema update may take quite long (minutes on a medium sized site,
79 many hours on a large site).
80
81 If upgrading from before 1.11, and you are using a wiki as a commons
82 repository, make sure that it is updated as well. Otherwise, errors may arise
83 due to database schema changes.
84
85 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
86 new database fields are filled with data.
87
88 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
89 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
90 with MediaWiki 1.21.
91
92 Don't forget to always back up your database before upgrading!
93
94 See the file UPGRADE for more detailed upgrade instructions.
