1 == MediaWiki 1.29 ==
2
3 THIS IS NOT A RELEASE YET
4
5 MediaWiki 1.29 is an alpha-quality branch and is not recommended for use in
6 production.
7
8 === Configuration changes in 1.29 ===
9 * Default cookie expiration time has been reduced to 30 days. Login cookie expiration time is
10 kept at 180 days.
11 * A new configuration variable has been added: $wgCookieSetOnAutoblock. This
12 determines whether to set a cookie when a user is autoblocked. Doing so means
13 that a blocked user, even after logging out and moving to a new IP address,
14 will still be blocked.
15 * The resetpassword right and associated password reset capture feature has
16 been removed.
17
18 === New features in 1.29 ===
19 * (T5233) A cookie can now be set when a user is autoblocked, to track that user if
20 they move to a new IP address. This is disabled by default.
21
22 === External library changes in 1.29 ===
23
24 ==== Upgraded external libraries ====

31 === Bug fixes in 1.29 ===
32
33 === Action API changes in 1.29 ===
34 * Submitting sensitive authentication request parameters to action=clientlogin,
35 action=createaccount, action=linkaccount, and action=changeauthenticationdata
36 in the query string is now an error. They should be submitted in the POST
37 body instead.
38 * The capture option for action=resetpassword has been removed
39 * action=clearhasmsg now requires a POST.
40
41 === Action API internal changes in 1.29 ===
42
43 === Languages updated in 1.29 ===
44
45 MediaWiki supports over 350 languages. Many localisations are updated
46 regularly. Below only new and removed languages are listed, as well as
47 changes to languages because of Phabricator reports.
48
49 ==== No fallback for Ukrainian ====
50 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
51 language will now use the default fallback language: English. When a translation
52 to Ukrainian is not available, an English string will be shown.
53
54 === Other changes in 1.29 ===
55 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
56 SearchEngineFactory::getSearchEngineClass() instead.
57 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
58 required as all sessions are stored in Object Cache now.
59 * MWHttpRequest::execute() should be considered to return a StatusValue; the
60 Status return type is deprecated.
61 * User::edits() (deprecated in 1.21) was removed.
62 * Xml::escapeJsString() (deprecated in 1.21) was removed.
63
64 == Compatibility ==
65
66 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
67 HHVM 3.6.5 or later.
68
69 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
70 support for them is somewhat less mature. There is experimental support for
71 Oracle and Microsoft SQL Server.
72
73 The supported versions are:
74
75 * MySQL 5.0.3 or later
76 * PostgreSQL 8.3 or later
77 * SQLite 3.3.7 or later
78 * Oracle 9.0.1 or later
79 * Microsoft SQL Server 2005 (9.00.1399)
80
81 == Upgrading ==
82
83 1.29 has several database changes since 1.28, and will not work without schema
84 updates. Note that due to changes to some very large tables like the revision
85 table, the schema update may take quite long (minutes on a medium sized site,
86 many hours on a large site).
87
88 If upgrading from before 1.11, and you are using a wiki as a commons
89 repository, make sure that it is updated as well. Otherwise, errors may arise
90 due to database schema changes.
91
92 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
93 new database fields are filled with data.
94
95 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
96 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
97 with MediaWiki 1.21.
98
99 Don't forget to always back up your database before upgrading!
100
101 See the file UPGRADE for more detailed upgrade instructions.
