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.
37 === New features in 1.29 ===
38 * (T5233) A cookie can now be set when a user is autoblocked, to track that user
39 if they move to a new IP address. This is disabled by default.
40 * Added ILocalizedException interface to standardize the use of localized
41 exceptions, largely so the API can handle them more sensibly.
42 * Blocks created automatically by MediaWiki, such as for configured proxies or
43 dnsbls, are now indicated as such and use a new i18n message when displayed.
44 * Added new $wgHTTPImportTimeout setting. Sets timeout for
45 downloading the XML dump during a transwiki import in seconds.
46 * Parser limit report is now available in machine-readable format to JavaScript
47 via mw.config.get('wgPageParseReport').
48 * Added $wgSoftBlockRanges, to allow for automatically blocking anonymous edits
49 from certain IP ranges (e.g. private IPs).
50 * (T59603) Added new magic word {{PAGELANGUAGE}} which returns the language code
51 of the page being parsed.
52 * HTML5 form validation attributes will no longer be suppressed. Originally
53 browsers had poor support for them, but modern browsers handle them fine.
54 This might affect some forms that used them and only worked because the
55 attributes were not actually being set.
56 * Expiry times can now be specified when users are added to user groups.
58 === External library changes in 1.29 ===
60 ==== Upgraded external libraries ====
61 * Added wikimedia/timestamp v1.0.0.
62 * Updated QUnit from v1.22.0 to v1.23.1.
63 * Updated cssjanus from v1.1.2 to 1.1.3.
64 * Updated psr/log from v1.0.0 to v1.0.2.
65 * Update Moment.js from v2.8.4 to v2.15.0.
67 ==== New external libraries ====
69 ==== Removed and replaced external libraries ====
71 === Bug fixes in 1.29 ===
72 * (T62604) Core parser functions returning a number now format the number according
73 to the page content language, not wiki content language.
74 * (T27187) Search suggestions based on jquery.suggestions will now correctly only
75 highlight prefix matches in the results.
76 * (T157035) "new mw.Uri()" was ignoring options when using default URI.
78 === Action API changes in 1.29 ===
79 * Submitting sensitive authentication request parameters to action=login,
80 action=clientlogin, action=createaccount, action=linkaccount, and
81 action=changeauthenticationdata in the query string is now an error. They
82 should be submitted in the POST body instead.
83 * The capture option for action=resetpassword has been removed
84 * action=clearhasmsg now requires a POST.
85 * (T47843) API errors and warnings may be requested in non-English languages
86 using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
87 * API error codes may have changed. Most notably, errors from modules using
88 parameter prefixes (e.g. all query submodules) will no longer be prefixed.
89 * ApiPageSet-using modules will report the 'invalidreason' using the specified
91 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
92 'errors' subelements (as applicable) instead of 'message'.
93 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
94 * action=move now reports errors when moving the talk page as an array under
95 key 'talkmove-errors', rather than using 'talkmove-error-code' and
96 'talkmove-error-info'. The format for subpage move errors has also changed.
97 * action=revisiondelete no longer includes a "rendered" property on warnings
98 and errors for each item. Use errorformat=wikitext if you're wanting parsed
100 * action=rollback no longer returns a "messageHtml" property. Use
101 errorformat=html if you're wanting HTML formatting of error messages.
102 * action=upload now reports optional stash failures as an array under key
103 'stasherrors' rather than a 'stashfailed' text string.
104 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
105 no longer returns a 'message' on success.
106 * Added action=validatepassword to validate passwords for the account creation
107 and password change forms.
108 * action=purge now requires a POST.
110 === Action API internal changes in 1.29 ===
111 * New methods were added to ApiBase to handle errors and warnings using i18n
112 keys. Methods for using hard-coded English messages were deprecated:
113 * ApiBase::dieUsage() was deprecated
114 * ApiBase::dieUsageMsg() was deprecated
115 * ApiBase::dieUsageMsgOrDebug() was deprecated
116 * ApiBase::getErrorFromStatus() was deprecated
117 * ApiBase::parseMsg() was deprecated
118 * ApiBase::setWarning() was deprecated
119 * ApiBase::$messageMap is no longer public. Code attempting to access it will
120 result in a PHP fatal error.
121 * The $message parameter to the ApiCheckCanExecute hook should be set to an
122 ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
123 code for ApiBase::parseMsg() will no longer work.
124 * UsageException is deprecated in favor of ApiUsageException. For the time
125 being ApiUsageException is a subclass of UsageException to allow things that
126 catch only UsageException to still function properly.
127 * If, for some strange reason, code was using an ApiErrorFormatter instead of
128 ApiErrorFormatter_BackCompat, note that the result format has changed and
129 various methods now take a module path rather than a module name.
130 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
131 from the message key, and maps some message keys for backwards compatibility.
133 === Languages updated in 1.29 ===
135 MediaWiki supports over 350 languages. Many localisations are updated
136 regularly. Below only new and removed languages are listed, as well as
137 changes to languages because of Phabricator reports.
139 * Based as always on linguistic studies on intelligibility and language
140 knowledge by geography, language fallbacks have been expanded. When a
141 translation is missing in the user's preferred interface language, the
142 corresponding translation for the fallback language will be used instead.
143 English will only be used as last resort when there are no translations.
144 Some configurations (such as date formats and gender namespaces) have also
145 been updated when using the fallback language's configuration was inadequate.
146 The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
147 ca ↔ oc; hsb ↔ dsb; io → eo; mdf → ru; pnt → el; roa-tara → it; rup → ro;
149 * (T155957) Talk Namespaces for Javanese language (jv) have been updated.
151 ==== No fallback for Ukrainian ====
152 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
153 language will now use the default fallback language: English. When a translation
154 to Ukrainian is not available, an English string will be shown.
156 === Other changes in 1.29 ===
157 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
158 SearchEngineFactory::getSearchEngineClass() instead.
159 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
160 required as all sessions are stored in Object Cache now.

162 Status return type is deprecated.

195 * wiki.phtml entry point was removed. Refer to index.php instead. If you want "wiki.phtml"
196 URLs to continue to work, set up redirects. In Apache, this can be done by enabling

248 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
251 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
252 support for them is somewhat less mature. There is experimental support for
253 Oracle and Microsoft SQL Server.
255 The supported versions are:
257 * MySQL 5.0.3 or later
258 * PostgreSQL 8.3 or later
259 * SQLite 3.3.7 or later
260 * Oracle 9.0.1 or later
261 * Microsoft SQL Server 2005 (9.00.1399)
265 1.29 has several database changes since 1.28, and will not work without schema
266 updates. Note that due to changes to some very large tables like the revision
267 table, the schema update may take quite long (minutes on a medium sized site,
268 many hours on a large site).
270 If upgrading from before 1.11, and you are using a wiki as a commons
271 repository, make sure that it is updated as well. Otherwise, errors may arise
272 due to database schema changes.
274 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
275 new database fields are filled with data.
277 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
278 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
281 Don't forget to always back up your database before upgrading!
283 See the file UPGRADE for more detailed upgrade instructions.
285 For notes on 1.28.x and older releases, see HISTORY.
