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.
31 * A temporary feature flag, $wgDisableUserGroupExpiry, is provided to disable
32 new features that rely on the schema changes to the user_groups table. This
33 feature flag will likely be removed before 1.29 is released.
34 * (T158474) "Unknown user" has been added to $wgReservedUsernames.
35 * (T156983) $wgRateLimitsExcludedIPs now accepts CIDR ranges as well as single IPs.
36 * $wgDummyLanguageCodes is deprecated. Additional language code mappings may be
37 added to $wgExtraLanguageCodes instead.
39 === New features in 1.29 ===
40 * (T5233) A cookie can now be set when a user is autoblocked, to track that user
41 if they move to a new IP address. This is disabled by default.
42 * Added ILocalizedException interface to standardize the use of localized
43 exceptions, largely so the API can handle them more sensibly.
44 * Blocks created automatically by MediaWiki, such as for configured proxies or
45 dnsbls, are now indicated as such and use a new i18n message when displayed.
46 * Added new $wgHTTPImportTimeout setting. Sets timeout for
47 downloading the XML dump during a transwiki import in seconds.
48 * Parser limit report is now available in machine-readable format to JavaScript
49 via mw.config.get('wgPageParseReport').
50 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
51 from certain IP ranges (e.g. private IPs).
52 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
53 of the page being parsed.
54 * HTML5 form validation attributes will no longer be suppressed. Originally
55 browsers had poor support for them, but modern browsers handle them fine.
56 This might affect some forms that used them and only worked because the
57 attributes were not actually being set.
58 * Expiry times can now be specified when users are added to user groups.
59 * Completely new user interface for the RecentChanges page, which
60 structures filters into user-friendly groups. This has corresponding
61 changes to how filters are registered by core and extensions.
63 === External library changes in 1.29 ===

82 * (T62604) Core parser functions returning a number now format the number according
83 to the page content language, not wiki content language.
84 * (T27187) Search suggestions based on jquery.suggestions will now correctly only
85 highlight prefix matches in the results.
86 * (T157035) "new mw.Uri()" was ignoring options when using default URI.

93 * (T125177) SECURITY: API parameters may now be marked as "sensitive" to keep
94 their values out of the logs.

101 === Action API changes in 1.29 ===
102 * Submitting sensitive authentication request parameters to action=login,
103 action=clientlogin, action=createaccount, action=linkaccount, and
104 action=changeauthenticationdata in the query string is now an error. They
105 should be submitted in the POST body instead.
106 * The capture option for action=resetpassword has been removed
107 * action=clearhasmsg now requires a POST.
108 * (T47843) API errors and warnings may be requested in non-English languages
109 using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
110 * API error codes may have changed. Most notably, errors from modules using
111 parameter prefixes (e.g. all query submodules) will no longer be prefixed.
112 * ApiPageSet-using modules will report the 'invalidreason' using the specified
114 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
115 'errors' subelements (as applicable) instead of 'message'.
116 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
117 * action=move now reports errors when moving the talk page as an array under
118 key 'talkmove-errors', rather than using 'talkmove-error-code' and
119 'talkmove-error-info'. The format for subpage move errors has also changed.
120 * action=revisiondelete no longer includes a "rendered" property on warnings
121 and errors for each item. Use errorformat=wikitext if you're wanting parsed
123 * action=rollback no longer returns a "messageHtml" property. Use
124 errorformat=html if you're wanting HTML formatting of error messages.
125 * action=upload now reports optional stash failures as an array under key
126 'stasherrors' rather than a 'stashfailed' text string.
127 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
128 no longer returns a 'message' on success.
129 * Added action=validatepassword to validate passwords for the account creation
130 and password change forms.
131 * action=purge now requires a POST.
132 * There is a new `languagevariants` siprop for action=query&meta=siteinfo,
133 which returns a list of languages with active LanguageConverter instances.
134 * action=query&query=allpages will no longer filter redirects using a database
135 query in miser mode. This may result in less results being returned than were
138 === Action API internal changes in 1.29 ===
139 * New methods were added to ApiBase to handle errors and warnings using i18n
140 keys. Methods for using hard-coded English messages were deprecated:
141 * ApiBase::dieUsage() was deprecated
142 * ApiBase::dieUsageMsg() was deprecated
143 * ApiBase::dieUsageMsgOrDebug() was deprecated
144 * ApiBase::getErrorFromStatus() was deprecated
145 * ApiBase::parseMsg() was deprecated
146 * ApiBase::setWarning() was deprecated
147 * ApiBase::$messageMap is no longer public. Code attempting to access it will
148 result in a PHP fatal error.
149 * The $message parameter to the ApiCheckCanExecute hook should be set to an
150 ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
151 code for ApiBase::parseMsg() will no longer work.
152 * UsageException is deprecated in favor of ApiUsageException. For the time
153 being ApiUsageException is a subclass of UsageException to allow things that
154 catch only UsageException to still function properly.
155 * If, for some strange reason, code was using an ApiErrorFormatter instead of
156 ApiErrorFormatter_BackCompat, note that the result format has changed and
157 various methods now take a module path rather than a module name.
158 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
159 from the message key, and maps some message keys for backwards compatibility.
160 * API parameters may now be marked as "sensitive" to keep their values out of
163 === Languages updated in 1.29 ===
165 MediaWiki supports over 350 languages. Many localisations are updated
166 regularly. Below only new and removed languages are listed, as well as
167 changes to languages because of Phabricator reports.
169 * Based as always on linguistic studies on intelligibility and language
170 knowledge by geography, language fallbacks have been expanded. When a
171 translation is missing in the user's preferred interface language, the
172 corresponding translation for the fallback language will be used instead.
173 English will only be used as last resort when there are no translations.
174 Some configurations (such as date formats and gender namespaces) have also
175 been updated when using the fallback language's configuration was inadequate.
176 The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
177 ca ↔ oc; hsb ↔ dsb; io → eo; mdf → ru; pnt → el; roa-tara → it; rup → ro;
179 * (T137376) New language support: Atikamekw (atj).
180 * (T155957) Talk Namespaces for Javanese language (jv) have been updated.
182 ==== No fallback for Ukrainian ====
183 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
184 language will now use the default fallback language: English. When a translation
185 to Ukrainian is not available, an English string will be shown.
187 === Other changes in 1.29 ===
188 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
189 SearchEngineFactory::getSearchEngineClass() instead.
190 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
191 required as all sessions are stored in Object Cache now.
192 * MWHttpRequest::execute() should be considered to return a StatusValue; the
193 Status return type is deprecated.

226 * wiki.phtml entry point was removed. Refer to index.php instead. If you want "wiki.phtml"
227 URLs to continue to work, set up redirects. In Apache, this can be done by enabling
228 mod_rewrite and adding the following rules to your configuration:
232 RewriteRule ^/w/wiki\.phtml$ /w/index.php [R=301,L]

258 * User-like objects that are passed to SpecialUserRights and its subclasses are
259 now required to have a getGroupMemberships() method. See UserRightsProxy for

275 * HTMLFileCache::newFromTitle() (deprecated in 1.24) was removed.
276 * BREAKING CHANGE: Internal signature changes to ChangesListSpecialPage
277 and subclasses. It should only break if you call buildMainQueryConds
278 (changed to buildQuery with new signature) or doMainQuery (new
279 signature). Subclasses are likely to call at least doMainQuery
280 (possibly both), but other classes might too, because they were
282 Also, some related hooks were deprecated, but this is not yet a
284 * Removed 'jquery.arrowSteps' module. (deprecated since 1.28)
285 * The 'jquery.autoEllipsis' ResourceLoader module is now deprecated.
286 * WikiRevision::$fileIsTemp was deprecated.
287 * WikiRevision::$importer was deprecated.
288 * WikiRevision::$user was deprecated.
289 * Article::getLastPurgeTimestamp(), WikiPage::getLastPurgeTimestamp(), and the
290 WikiPage::PURGE_* constants are deprecated, and the functions will always
291 return false. They were a hack for an issue that has since been fixed.
292 * Hook 'EditPageBeforeEditChecks' is now deprecated. Instead use the new hook
293 'EditPageGetCheckboxesDefinition', or 'EditPage::showStandardInputs:options'
294 if you don't actually care about checkboxes and just want to add some HTML
296 * Selflinks are now rendered as href-less <a> tags with the class mw-selflink
297 rather than <strong> tags. The old class name, "selflink", was deprecated
298 and will be removed in a future release. (T160480)
299 * (T156184) $wgRawHtml will no longer apply to internationalization messages.
300 * Browser support for non-ES5 JavaScript browsers, including Android 2,
301 Opera <12.10, and Internet Explorer 9, was lowered from Grade A to Grade C.
305 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
308 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
309 support for them is somewhat less mature. There is experimental support for
310 Oracle and Microsoft SQL Server.
312 The supported versions are:
314 * MySQL 5.0.3 or later
315 * PostgreSQL 8.3 or later
316 * SQLite 3.3.7 or later
317 * Oracle 9.0.1 or later
318 * Microsoft SQL Server 2005 (9.00.1399)
322 1.29 has several database changes since 1.28, and will not work without schema
323 updates. Note that due to changes to some very large tables like the revision
324 table, the schema update may take quite long (minutes on a medium sized site,
325 many hours on a large site).
327 If upgrading from before 1.11, and you are using a wiki as a commons
328 repository, make sure that it is updated as well. Otherwise, errors may arise
329 due to database schema changes.
331 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
332 new database fields are filled with data.
334 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
335 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
338 Don't forget to always back up your database before upgrading!
340 See the file UPGRADE for more detailed upgrade instructions.
