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
10 expiration time is 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
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
27 * Subpages are now enabled by default in the Template namespace. Set
28 $wgNamespacesWithSubpages[NS_TEMPLATE] to false to keep the old behavior.
29 * $wgRunJobsAsync is now false by default (T142751). This change only affects
30 wikis with $wgJobRunRate > 0.
32 === New features in 1.29 ===
33 * (T5233) A cookie can now be set when a user is autoblocked, to track that user
34 if they move to a new IP address. This is disabled by default.
35 * Added ILocalizedException interface to standardize the use of localized
36 exceptions, largely so the API can handle them more sensibly.
37 * Blocks created automatically by MediaWiki, such as for configured proxies or
38 dnsbls, are now indicated as such and use a new i18n message when displayed.
39 * Added new $wgHTTPImportTimeout setting. Sets timeout for
40 downloading the XML dump during a transwiki import in seconds.
41 * Parser limit report is now available in machine-readable format to JavaScript
42 via mw.config.get('wgPageParseReport').
43 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
44 from certain IP ranges (e.g. private IPs).
45 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
46 of the page being parsed.
47 * Added JavaScript that provides as-you-type suggestions for reason
48 on the block, delete and protect forms.
49 * HTML5 form validation attributes will no longer be suppressed. Originally
50 browsers had poor support for them, but modern browsers handle them fine.
51 This might affect some forms that used them and only worked because the
52 attributes were not actually being set.
54 === External library changes in 1.29 ===
56 ==== Upgraded external libraries ====
57 * Updated QUnit from v1.22.0 to v1.23.1.
59 ==== New external libraries ====
61 ==== Removed and replaced external libraries ====
63 === Bug fixes in 1.29 ===
64 * (T62604) Core parser functions returning a number now format the number according
65 to the page content language, not wiki content language.
67 === Action API changes in 1.29 ===
68 * Submitting sensitive authentication request parameters to action=clientlogin,
69 action=createaccount, action=linkaccount, and action=changeauthenticationdata
70 in the query string is now an error. They should be submitted in the POST
72 * The capture option for action=resetpassword has been removed
73 * action=clearhasmsg now requires a POST.
74 * (T47843) API errors and warnings may be requested in non-English languages
75 using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
76 * API error codes may have changed. Most notably, errors from modules using
77 parameter prefixes (e.g. all query submodules) will no longer be prefixed.
78 * ApiPageSet-using modules will report the 'invalidreason' using the specified
80 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
81 'errors' subelements (as applicable) instead of 'message'.
82 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
83 * action=move now reports errors when moving the talk page as an array under
84 key 'talkmove-errors', rather than using 'talkmove-error-code' and
85 'talkmove-error-info'. The format for subpage move errors has also changed.
86 * action=revisiondelete no longer includes a "rendered" property on warnings
87 and errors for each item. Use errorformat=wikitext if you're wanting parsed
89 * action=rollback no longer returns a "messageHtml" property. Use
90 errorformat=html if you're wanting HTML formatting of error messages.
91 * action=upload now reports optional stash failures as an array under key
92 'stasherrors' rather than a 'stashfailed' text string.
93 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
94 no longer returns a 'message' on success.
95 * Added action=validatepassword to validate passwords for the account creation
96 and password change forms.
98 === Action API internal changes in 1.29 ===
99 * New methods were added to ApiBase to handle errors and warnings using i18n
100 keys. Methods for using hard-coded English messages were deprecated:
101 * ApiBase::dieUsage() was deprecated
102 * ApiBase::dieUsageMsg() was deprecated
103 * ApiBase::dieUsageMsgOrDebug() was deprecated
104 * ApiBase::getErrorFromStatus() was deprecated
105 * ApiBase::parseMsg() was deprecated
106 * ApiBase::setWarning() was deprecated
107 * ApiBase::$messageMap is no longer public. Code attempting to access it will
108 result in a PHP fatal error.
109 * The $message parameter to the ApiCheckCanExecute hook should be set to an
110 ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
111 code for ApiBase::parseMsg() will no longer work.
112 * UsageException is deprecated in favor of ApiUsageException. For the time
113 being ApiUsageException is a subclass of UsageException to allow things that
114 catch only UsageException to still function properly.
115 * If, for some strange reason, code was using an ApiErrorFormatter instead of
116 ApiErrorFormatter_BackCompat, note that the result format has changed and
117 various methods now take a module path rather than a module name.
118 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
119 from the message key, and maps some message keys for backwards compatibility.
121 === Languages updated in 1.29 ===
123 MediaWiki supports over 350 languages. Many localisations are updated
124 regularly. Below only new and removed languages are listed, as well as
125 changes to languages because of Phabricator reports.
127 * Based as always on linguistic studies on intelligibility and language
128 knowledge by geography, language fallbacks have been expanded. When a
129 translation is missing in the user's preferred interface language, the
130 corresponding translation for the fallback language will be used instead.
131 English will only be used as last resort when there are no translations.
132 Some configurations (such as date formats and gender namespaces) have also
133 been updated when using the fallback language's configuration was inadequate.
134 The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
135 hsb ↔ dsb, io → eo, mdf → ru, pnt → el, roa-tara → it.
137 ==== No fallback for Ukrainian ====
138 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
139 language will now use the default fallback language: English. When a translation
140 to Ukrainian is not available, an English string will be shown.
142 === Other changes in 1.29 ===
143 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
144 SearchEngineFactory::getSearchEngineClass() instead.
145 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
146 required as all sessions are stored in Object Cache now.
147 * MWHttpRequest::execute() should be considered to return a StatusValue; the
148 Status return type is deprecated.
149 * User::edits() (deprecated in 1.21) was removed.
150 * Xml::escapeJsString() (deprecated in 1.21) was removed.
151 * Article::getText() and Article::prepareTextForEdit() (deprecated in 1.21)
153 * Article::getAutosummary() and WikiPage::getAutosummary() (deprecated in 1.21)
155 * Hooks ArticleViewCustom, EditPageGetDiffText and ShowRawCssJs (deprecated in 1.21)
157 * Class RevisiondeleteAction (deprecated in 1.25) was removed.
158 * WikiPage::prepareTextForEdit() (deprecated in 1.21) was removed.
159 * WikiPage::getText() (deprecated in 1.21) was removed.
160 * Article::fetchContent() (deprecated in 1.21) was removed.
161 * User::getPassword() (deprecated in 1.27) was removed.
162 * User::getTemporaryPassword() (deprecated in 1.27) was removed.
163 * User::isPasswordReminderThrottled() (deprecated in 1.27) was removed.
164 * Class FSRepo (deprecated in 1.19) was removed.
165 * WebRequest::checkSessionCookie() (deprecated in 1.27) was removed. Use
166 \MediaWiki\Session\SessionManager::singleton()->getPersistedSessionId() instead.
167 * Class ImageGallery (deprecated in 1.22) was removed.
168 Use ImageGalleryBase::factory instead.
169 * Title::moveNoAuth() (deprecated in 1.25) was removed. Use MovePage class instead.
170 * Hook UnknownAction (deprecated in 1.19) was actually deprecated (it will now
171 emit warnings). Create a subclass of Action and add it to $wgActions instead.
172 * WikiRevision::getText() (deprecated since 1.21) is no longer marked deprecated.
173 * Linker::getInterwikiLinkAttributes() (deprecated since 1.25) was removed.
174 * Linker::getInternalLinkAttributes() (deprecated since 1.25) was removed.
175 * Linker::getInternalLinkAttributesObj() (deprecated since 1.25) was removed.
176 * Linker::getLinkAttributesInternal() (deprecated since 1.25) was removed.
177 * RedisConnectionPool::handleException (deprecated since 1.23) was removed.
178 * The static properties mw.Api.errors and mw.Api.warnings, containing incomplete
179 and outdated lists of errors/warnings returned by the API, are now deprecated.
180 * wiki.phtml entry point was removed. Refer to index.php instead. If you want "wiki.phtml"
181 URLs to continue to work, set up redirects. In Apache, this can be done by enabling
182 mod_rewrite and adding the following rules to your configuration:
186 RewriteRule ^/w/wiki\.phtml$ /w/index.php [R=301,L]
190 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
193 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
194 support for them is somewhat less mature. There is experimental support for
195 Oracle and Microsoft SQL Server.
197 The supported versions are:
199 * MySQL 5.0.3 or later
200 * PostgreSQL 8.3 or later
201 * SQLite 3.3.7 or later
202 * Oracle 9.0.1 or later
203 * Microsoft SQL Server 2005 (9.00.1399)
207 1.29 has several database changes since 1.28, and will not work without schema
208 updates. Note that due to changes to some very large tables like the revision
209 table, the schema update may take quite long (minutes on a medium sized site,
210 many hours on a large site).
212 If upgrading from before 1.11, and you are using a wiki as a commons
213 repository, make sure that it is updated as well. Otherwise, errors may arise
214 due to database schema changes.
216 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
217 new database fields are filled with data.
219 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
220 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
223 Don't forget to always back up your database before upgrading!
225 See the file UPGRADE for more detailed upgrade instructions.
