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.
28 * $wgRunJobsAsync is now false by default (T142751). This change only affects
29 wikis with $wgJobRunRate > 0.
31 === New features in 1.29 ===
32 * (T5233) A cookie can now be set when a user is autoblocked, to track that user if
33 they move to a new IP address. This is disabled by default.
34 * Added ILocalizedException interface to standardize the use of localized
35 exceptions, largely so the API can handle them more sensibly.
36 * Blocks created automatically by MediaWiki, such as for configured proxies or
37 dnsbls, are now indicated as such and use a new i18n message when displayed.
38 * Added new $wgHTTPImportTimeout setting. Sets timeout for
39 downloading the XML dump during a transwiki import in seconds.
41 === External library changes in 1.29 ===
43 ==== Upgraded external libraries ====
44 * Updated QUnit from v1.22.0 to v1.23.1.
46 ==== New external libraries ====
48 ==== Removed and replaced external libraries ====
50 === Bug fixes in 1.29 ===
51 * (T62604) Core parser functions returning a number now format the number according
52 to the page content language, not wiki content language.
54 === Action API changes in 1.29 ===
55 * Submitting sensitive authentication request parameters to action=clientlogin,
56 action=createaccount, action=linkaccount, and action=changeauthenticationdata
57 in the query string is now an error. They should be submitted in the POST
59 * The capture option for action=resetpassword has been removed
60 * action=clearhasmsg now requires a POST.
61 * (T47843) API errors and warnings may be requested in non-English languages
62 using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
63 * API error codes may have changed. Most notably, errors from modules using
64 parameter prefixes (e.g. all query submodules) will no longer be prefixed.
65 * ApiPageSet-using modules will report the 'invalidreason' using the specified
67 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
68 'errors' subelements (as applicable) instead of 'message'.
69 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
70 * action=move now reports errors when moving the talk page as an array under
71 key 'talkmove-errors', rather than using 'talkmove-error-code' and
72 'talkmove-error-info'. The format for subpage move errors has also changed.
73 * action=revisiondelete no longer includes a "rendered" property on warnings
74 and errors for each item. Use errorformat=wikitext if you're wanting parsed
76 * action=rollback no longer returns a "messageHtml" property. Use
77 errorformat=html if you're wanting HTML formatting of error messages.
78 * action=upload now reports optional stash failures as an array under key
79 'stasherrors' rather than a 'stashfailed' text string.
80 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
81 no longer returns a 'message' on success.
82 * Added action=validatepassword to validate passwords for the account creation
83 and password change forms.
85 === Action API internal changes in 1.29 ===
86 * New methods were added to ApiBase to handle errors and warnings using i18n
87 keys. Methods for using hard-coded English messages were deprecated:
88 * ApiBase::dieUsage() was deprecated
89 * ApiBase::dieUsageMsg() was deprecated
90 * ApiBase::dieUsageMsgOrDebug() was deprecated
91 * ApiBase::getErrorFromStatus() was deprecated
92 * ApiBase::parseMsg() was deprecated
93 * ApiBase::setWarning() was deprecated
94 * ApiBase::$messageMap is no longer public. Code attempting to access it will
95 result in a PHP fatal error.
96 * The $message parameter to the ApiCheckCanExecute hook should be set to an
97 ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
98 code for ApiBase::parseMsg() will no longer work.
99 * UsageException is deprecated in favor of ApiUsageException. For the time
100 being ApiUsageException is a subclass of UsageException to allow things that
101 catch only UsageException to still function properly.
102 * If, for some strange reason, code was using an ApiErrorFormatter instead of
103 ApiErrorFormatter_BackCompat, note that the result format has changed and
104 various methods now take a module path rather than a module name.
105 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
106 from the message key, and maps some message keys for backwards compatibility.
108 === Languages updated in 1.29 ===
110 MediaWiki supports over 350 languages. Many localisations are updated
111 regularly. Below only new and removed languages are listed, as well as
112 changes to languages because of Phabricator reports.
114 * Based as always on linguistic studies on intelligibility and language
115 knowledge by geography, language fallbacks have been expanded. When a
116 translation is missing in the user's preferred interface language, the
117 corresponding translation for the fallback language will be used instead.
118 English will only be used as last resort when there are no translations.
119 Some configurations (such as date formats and gender namespaces) have also
120 been updated when using the fallback language's configuration was inadequate.
121 The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
122 hsb ↔ dsb, io → eo, mdf → ru, pnt → el, roa-tara → it.
124 ==== No fallback for Ukrainian ====
125 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
126 language will now use the default fallback language: English. When a translation
127 to Ukrainian is not available, an English string will be shown.
129 === Other changes in 1.29 ===
130 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
131 SearchEngineFactory::getSearchEngineClass() instead.
132 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
133 required as all sessions are stored in Object Cache now.
134 * MWHttpRequest::execute() should be considered to return a StatusValue; the
135 Status return type is deprecated.
136 * User::edits() (deprecated in 1.21) was removed.
137 * Xml::escapeJsString() (deprecated in 1.21) was removed.
138 * Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
140 * Article::getAutosummary() and WikiPage::getAutosummary (deprecated in 1.21)
142 * Hooks ArticleViewCustom, EditPageGetDiffText and ShowRawCssJs (deprecated in 1.21)
144 * Class RevisiondeleteAction (deprecated in 1.25) was removed.
145 * WikiPage::prepareTextForEdit() (deprecated in 1.21) was removed.
146 * WikiPage::getText() (deprecated in 1.21) was removed.
147 * Article::fetchContent() (deprecated in 1.21) was removed.
148 * User::getPassword() (deprecated in 1.27) was removed.
149 * User::getTemporaryPassword() (deprecated in 1.27) was removed.
150 * User::isPasswordReminderThrottled() (deprecated in 1.27) was removed.
151 * FSRepo (deprecated in 1.19) was removed.
152 * WebRequest::checkSessionCookie() (deprecated in 1.27) was removed. Use
153 \MediaWiki\Session\SessionManager::singleton()->getPersistedSessionId() instead.
154 * Class ImageGallery (deprecated in 1.22) was removed.
155 Use ImageGalleryBase::factory instead.
156 * Title::moveNoAuth() (deprecated in 1.25) was removed. Use MovePage class instead.
157 * Hook UnknownAction (deprecated in 1.19) was actually deprecated (it will now emit warnings).
158 Create a subclass of Action, and add it to $wgActions instead.
162 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
165 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
166 support for them is somewhat less mature. There is experimental support for
167 Oracle and Microsoft SQL Server.
169 The supported versions are:
171 * MySQL 5.0.3 or later
172 * PostgreSQL 8.3 or later
173 * SQLite 3.3.7 or later
174 * Oracle 9.0.1 or later
175 * Microsoft SQL Server 2005 (9.00.1399)
179 1.29 has several database changes since 1.28, and will not work without schema
180 updates. Note that due to changes to some very large tables like the revision
181 table, the schema update may take quite long (minutes on a medium sized site,
182 many hours on a large site).
184 If upgrading from before 1.11, and you are using a wiki as a commons
185 repository, make sure that it is updated as well. Otherwise, errors may arise
186 due to database schema changes.
188 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
189 new database fields are filled with data.
191 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
192 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
195 Don't forget to always back up your database before upgrading!
197 See the file UPGRADE for more detailed upgrade instructions.
