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 * HTML5 form validation attributes will no longer be suppressed. Originally
48 browsers had poor support for them, but modern browsers handle them fine.
49 This might affect some forms that used them and only worked because the
50 attributes were not actually being set.
52 === External library changes in 1.29 ===
54 ==== Upgraded external libraries ====
55 * Updated QUnit from v1.22.0 to v1.23.1.
57 ==== New external libraries ====
59 ==== Removed and replaced external libraries ====
61 === Bug fixes in 1.29 ===
62 * (T62604) Core parser functions returning a number now format the number according
63 to the page content language, not wiki content language.
65 === Action API changes in 1.29 ===
66 * Submitting sensitive authentication request parameters to action=clientlogin,
67 action=createaccount, action=linkaccount, and action=changeauthenticationdata
68 in the query string is now an error. They should be submitted in the POST
70 * The capture option for action=resetpassword has been removed
71 * action=clearhasmsg now requires a POST.
72 * (T47843) API errors and warnings may be requested in non-English languages
73 using the new 'errorformat', 'errorlang', and 'errorsuselocal' parameters.
74 * API error codes may have changed. Most notably, errors from modules using
75 parameter prefixes (e.g. all query submodules) will no longer be prefixed.
76 * ApiPageSet-using modules will report the 'invalidreason' using the specified
78 * action=emailuser may return a "Warnings" status, and now returns 'warnings' and
79 'errors' subelements (as applicable) instead of 'message'.
80 * action=imagerotate returns an 'errors' subelement rather than 'errormessage'.
81 * action=move now reports errors when moving the talk page as an array under
82 key 'talkmove-errors', rather than using 'talkmove-error-code' and
83 'talkmove-error-info'. The format for subpage move errors has also changed.
84 * action=revisiondelete no longer includes a "rendered" property on warnings
85 and errors for each item. Use errorformat=wikitext if you're wanting parsed
87 * action=rollback no longer returns a "messageHtml" property. Use
88 errorformat=html if you're wanting HTML formatting of error messages.
89 * action=upload now reports optional stash failures as an array under key
90 'stasherrors' rather than a 'stashfailed' text string.
91 * action=watch reports 'errors' and 'warnings' instead of a single 'error', and
92 no longer returns a 'message' on success.
93 * Added action=validatepassword to validate passwords for the account creation
94 and password change forms.
96 === Action API internal changes in 1.29 ===
97 * New methods were added to ApiBase to handle errors and warnings using i18n
98 keys. Methods for using hard-coded English messages were deprecated:
99 * ApiBase::dieUsage() was deprecated
100 * ApiBase::dieUsageMsg() was deprecated
101 * ApiBase::dieUsageMsgOrDebug() was deprecated
102 * ApiBase::getErrorFromStatus() was deprecated
103 * ApiBase::parseMsg() was deprecated
104 * ApiBase::setWarning() was deprecated
105 * ApiBase::$messageMap is no longer public. Code attempting to access it will
106 result in a PHP fatal error.
107 * The $message parameter to the ApiCheckCanExecute hook should be set to an
108 ApiMessage. This is compatible with MediaWiki 1.27 and later. Returning a
109 code for ApiBase::parseMsg() will no longer work.
110 * UsageException is deprecated in favor of ApiUsageException. For the time
111 being ApiUsageException is a subclass of UsageException to allow things that
112 catch only UsageException to still function properly.
113 * If, for some strange reason, code was using an ApiErrorFormatter instead of
114 ApiErrorFormatter_BackCompat, note that the result format has changed and
115 various methods now take a module path rather than a module name.
116 * ApiMessageTrait::getApiCode() now strips 'apierror-' and 'apiwarn-' prefixes
117 from the message key, and maps some message keys for backwards compatibility.
119 === Languages updated in 1.29 ===
121 MediaWiki supports over 350 languages. Many localisations are updated
122 regularly. Below only new and removed languages are listed, as well as
123 changes to languages because of Phabricator reports.
125 * Based as always on linguistic studies on intelligibility and language
126 knowledge by geography, language fallbacks have been expanded. When a
127 translation is missing in the user's preferred interface language, the
128 corresponding translation for the fallback language will be used instead.
129 English will only be used as last resort when there are no translations.
130 Some configurations (such as date formats and gender namespaces) have also
131 been updated when using the fallback language's configuration was inadequate.
132 The new or reinstated language fallbacks are (after cs ↔ sk in 1.28):
133 hsb ↔ dsb, io → eo, mdf → ru, pnt → el, roa-tara → it.
135 ==== No fallback for Ukrainian ====
136 * (T39314) The fallback from Ukrainian to Russian was removed. The Ukrainian
137 language will now use the default fallback language: English. When a translation
138 to Ukrainian is not available, an English string will be shown.
140 === Other changes in 1.29 ===
141 * Database::getSearchEngine() (deprecated in 1.28) was removed. Use
142 SearchEngineFactory::getSearchEngineClass() instead.
143 * $wgSessionsInMemcached (deprecated in 1.20) was removed. No replacement is
144 required as all sessions are stored in Object Cache now.

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

214 MediaWiki 1.29 requires PHP 5.5.9 or later. There is experimental support for
217 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
218 support for them is somewhat less mature. There is experimental support for
219 Oracle and Microsoft SQL Server.
221 The supported versions are:
223 * MySQL 5.0.3 or later
224 * PostgreSQL 8.3 or later
225 * SQLite 3.3.7 or later
226 * Oracle 9.0.1 or later
227 * Microsoft SQL Server 2005 (9.00.1399)
231 1.29 has several database changes since 1.28, and will not work without schema
232 updates. Note that due to changes to some very large tables like the revision
233 table, the schema update may take quite long (minutes on a medium sized site,
234 many hours on a large site).
236 If upgrading from before 1.11, and you are using a wiki as a commons
237 repository, make sure that it is updated as well. Otherwise, errors may arise
238 due to database schema changes.
240 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
241 new database fields are filled with data.
243 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
244 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
247 Don't forget to always back up your database before upgrading!
249 See the file UPGRADE for more detailed upgrade instructions.
