3 THIS IS NOT A RELEASE YET
5 MediaWiki 1.29 is an alpha-quality branch and is not recommended for use in
8 === Configuration changes in 1.29 ===
9 * Default cookie expiration time has been reduced to 30 days. Login cookie expiration time is
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
17 * The $error parameter to the EmailUser hook should be set to a Status object
18 or boolean false. This should be compatible with at least MediaWiki 1.23 if
19 not earlier. Returning a raw HTML string is now deprecated.
20 * The $message parameter to the ApiCheckCanExecute hook should be set to an
21 ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
22 code for ApiBase::parseMsg() will no longer work.
23 * ApiBase::$messageMap is no longer public. Code attempting to access it will
24 result in a PHP fatal error.
25 * $wgUserEmailUseReplyTo is now true by default to work around restrictive DMARC policies.
26 * Subpages are now enabled by default in the Template namespace. Set
27 $wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
29 === New features in 1.29 ===
30 * (T5233) A cookie can now be set when a user is autoblocked, to track that user if
31 they move to a new IP address. This is disabled by default.
33 === External library changes in 1.29 ===
35 ==== Upgraded external libraries ====
36 * Updated QUnit from v1.22.0 to v1.23.1.
38 ==== New external libraries ====
40 ==== Removed and replaced external libraries ====
42 === Bug fixes in 1.29 ===
44 === Action API changes in 1.29 ===
45 * Submitting sensitive authentication request parameters to action=clientlogin,
46 action=createaccount, action=linkaccount, and action=changeauthenticationdata
47 in the query string is now an error. They should be submitted in the POST
49 * The capture option for action=resetpassword has been removed
50 * action=clearhasmsg now requires a POST.
51 * (T47843) API errors and warnings may be requested in non-English languages
52 using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
53 * API error codes may have changed. Most notably, errors from modules using
54 parameter prefixes (e.g. all query submodules) will no longer be prefixed.
55 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
56 'errors' subelements (as applicable) instead of 'message'.
57 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
58 * action=move now reports errors when moving the talk page as an array under
59 key 'talkmove-errors', rather than using 'talkmove-error-code' and
60 'talkmove-error-info'. The format for subpage move errors has also changed.
61 * action=revisiondelete no longer includes a "rendered" property on warnings
62 and errors for each item. Use errorformat=wikitext if you're wanting parsed
64 * action=rollback no longer returns a "messageHtml" property. Use
65 errorformat=html if you're wanting HTML formatting of error messages.
66 * action=upload now reports optional stash failures as an array under key
67 'stasherrors' rather than a 'stashfailed' text string.
68 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
69 no longer returns a 'message' on success.
71 === Action API internal changes in 1.29 ===
72 * New methods were added to ApiBase to handle errors and warnings using i18n
73 keys. Methods for using hard-coded English messages were deprecated:
74 * ApiBase::dieUsage() was deprecated
75 * ApiBase::dieUsageMsg() was deprecated
76 * ApiBase::dieUsageMsgOrDebug() was deprecated
77 * ApiBase::getErrorFromStatus() was deprecated
78 * ApiBase::parseMsg() was deprecated
79 * ApiBase::setWarning() was deprecated
80 * ApiBase::$messageMap is no longer public. Code attempting to access it will
81 result in a PHP fatal error.
82 * The $message parameter to the ApiCheckCanExecute hook should be set to an
83 ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
84 code for ApiBase::parseMsg() will no longer work.
85 * UsageException is deprecated in favor of ApiUsageException. For the time
86 being ApiUsageException is a subclass of UsageException to allow things that
87 catch only UsageException to still function properly.
88 * If, for some strange reason, code was using an ApiErrorFormatter instead of
89 ApiErrorFormatter_BackCompat, note that the result format has changed and
90 various methods now take a module path rather than a module name.
91 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
92 from the message key, and maps some message keys for backwards compatibility.
94 === Languages updated in 1.29 ===
96 MediaWiki supports over 350 languages. Many localisations are updated
97 regularly. Below only new and removed languages are listed, as well as
98 changes to languages because of Phabricator reports.
100 ==== No fallback for Ukrainian ====
101 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
102 language will now use the default fallback language: English. When a translation
103 to Ukrainian is not available, an English string will be shown.
105 === Other changes in 1.29 ===
106 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
107 SearchEngineFactory::getSearchEngineClass() instead.
108 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
109 required as all sessions are stored in Object Cache now.
110 * MWHttpRequest::execute() should be considered to return a StatusValue; the
111 Status return type is deprecated.
112 * User::edits() (deprecated in 1.21) was removed.
113 * Xml::escapeJsString() (deprecated in 1.21) was removed.
114 * Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
116 * Article::getAutosummary() and WikiPage::getAutosummary (deprecated in 1.21)
118 * Hooks ArticleViewCustom, EditPageGetDiffText and ShowRawCssJs (deprecated in 1.21)
120 * Class RevisiondeleteAction (deprecated in 1.25) was removed.

123 * Article::fetchContent() (deprecated in 1.21) was removed.
127 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
130 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
131 support for them is somewhat less mature. There is experimental support for
132 Oracle and Microsoft SQL Server.
134 The supported versions are:
136 * MySQL 5.0.3 or later
137 * PostgreSQL 8.3 or later
138 * SQLite 3.3.7 or later
139 * Oracle 9.0.1 or later
140 * Microsoft SQL Server 2005 (9.00.1399)
144 1.29 has several database changes since 1.28, and will not work without schema
145 updates. Note that due to changes to some very large tables like the revision
146 table, the schema update may take quite long (minutes on a medium sized site,
147 many hours on a large site).
149 If upgrading from before 1.11, and you are using a wiki as a commons
150 repository, make sure that it is updated as well. Otherwise, errors may arise
151 due to database schema changes.
153 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
154 new database fields are filled with data.
156 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
157 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
160 Don't forget to always back up your database before upgrading!
162 See the file UPGRADE for more detailed upgrade instructions.
