6 THIS IS NOT A RELEASE YET
8 MediaWiki 1.22 is an alpha-quality branch and is not recommended for use in
11 === Configuration changes in 1.22 ===
12 * $wgRedirectScript was removed. It was unused.
13 * Removed $wgLocalMessageCacheSerialized, it is now always true.
14 * When $wgUseVFormUserLogin is true, the redesign of Special:UserLogin is
15 activated; when $wgUseVFormCreateAccount is true, the redesign of
16 Special:UserLogin/signup is activated.
17 * $wgVectorUseIconWatch is now enabled by default.
19 === New features in 1.22 ===
20 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
21 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
22 the "eIOPTZ" formatting characters.
23 * EditWarning: A warning is shown when an editor leaves the edit form without
24 saving (enabled by default, users can opt-out via the 'useeditwarning'
25 preference). This feature was moved from the Vector extension, and is now part
26 of core for all skins. Take care when upgrading that you don't use an older
27 version of the Vector extension as this feature may conflict.
28 * New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
29 compact vertical form layout.
30 * New versions of login (Special:UserLogin) and create account
31 (Special:UserLogin/signup) forms. They are opt-in for now, controlled by
32 the $wgUseVFormUserLogin and $wgUseVFormCreateAccount settings or a 'useNew'
33 URL parameter trigger.
34 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
35 by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
36 * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
38 * (bug 25592) LogEventsList::showLogExtract() will now ignore various
39 Pager-related WebRequest parameters by default, as this is overwhelmingly
40 likely to be what was intended by users of the method. If any caller wishes
41 to use these parameters, the new param 'useRequestParams' may be set to true.
42 * mw.util.addPortletLink: Tooltip is no longer required to be plain (without
43 an accesskey in it already). As such it now rountrips. Creating a link with a
44 message as tooltip, grabbing the title attribute and using it to create
45 another portlet will work as expected.
46 * (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
47 page without namespace.
48 * BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
49 change their class name from .editsection to .mw-editsection and place them at
50 the end of the heading element instead of the beginning. Client-side code and
51 screen-scrapers will have to be adjusted to handle both cases (old HTML will
52 still be visible on cached page renders until they are purged); extensions
53 using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
55 * (bug 45535) introduced the new 'LanguageLinks' hook for manipulating the
56 language links associated with a page before display.
57 * Chosen (http://harvesthq.github.io/chosen/) was added as module 'jquery.chosen'
58 * HTMLForm will turn multiselect checkboxes into a Chosen interface when setting cssclass 'mw-chosen'
59 * rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches
60 of the specified languages instead of all of them.
61 * New GetNewMessagesAlert hook allowing extensions to disable or modify the new
63 * New wgUserNewMsgRevisionId JS global for logged in users. This will be null
64 if the user has no new talk page messages. Otherwise it will be set to the
65 revision ID of the oldest new talk page message. This will allow gadgets and
66 extensions to create their own new message alerts on the client side.
67 * mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace).
68 * mediawiki.log: Implemented log.deprecate. This method defines a property and
69 uses ES5 getter/setter to emit a warning when they are used.
71 === Bug fixes in 1.22 ===
72 * Disable Special:PasswordReset when $wgEnableEmail. Previously one could still
73 navigate to the page by entering the URL directly.
74 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
75 create an account on login due external authentication in some circumstances.
76 * (bug 23393) HTML <hN> headings containing line breaks are now handled
78 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
79 is now non-significant and not preserved in the HTML output.
80 * (bug 47218) Special:BlockList now handles correctly user names with spaces
81 when passed as subpage.
82 * Pager's properly validate which fields are allowed to be sorted on.
83 * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
84 Support for Mac "option" was added in 1.16, but the regex was never updated.
85 * (bug 46768) Usernames of blocking users now display correctly, even if numeric.
86 * (bug 39590) {{PAGESIZE}} for the current page and self-transclusions now
87 show the most up to date result always instead of being a revision behind.
88 * A bias in wfRandomString() toward digits 1-7 has been corrected. Generated
89 strings will now start with digits 0 and 8-f as often as they should.
91 === API changes in 1.22 ===
92 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
93 parameter has had no effect since MediaWiki 1.16, and so its removal is
94 unlikely to impact existing clients.
95 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
96 to action=feedwatchlist.
97 * WDDX formatted output will actually be formatted (and normal output will no
98 longer be), and will no longer choke on booleans.
99 * action=opensearch no longer silently ignores the format parameter.
100 * action=opensearch now supports format=jsonfm.
101 * list=usercontribs&ucprop=ids will now include the parent revision id.
102 * BREAKING CHANGE: action=parse no longer returns all langlinks for the page
103 with prop=langlinks by default. The new effectivelanglinks parameter will
104 request that the LanguageLinks hook be called to determine the effective
106 * BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
107 apply the new LanguageLinks hook, and thus only consider language links
108 stored in the database.
109 * (bug 47219) Allow specifying change type of Wikipedia feed items
110 * prop=imageinfo now allows setting iiurlheight without setting iiurlwidth
112 === Languages updated in 1.22===
114 MediaWiki supports over 350 languages. Many localisations are updated
115 regularly. Below only new and removed languages are listed, as well as
116 changes to languages because of Bugzilla reports.
118 === Other changes in 1.22 ===
119 * redirect.php was removed. It was unused.
120 * ClickTracking integration was dropped from the mediaWiki.user.bucket
121 JavaScript function. The 'tracked' option is now ignored.
122 * BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
123 were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
124 LegacyTemplate classes that supported them were removed as well and are now a
125 part of the Nostalgia extension.
126 * Event namespace used by jquery.makeCollapsible has been changed from
127 'mw-collapse' to 'mw-collapsible' for consistency with the module name.
128 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
129 with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
130 $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
131 use AuthPlugin for external authentication/authorization needs.
132 * The Quickbar feature of the legacy skin model and the last remnants of it
133 throughout the code base have been removed.
134 * Externaledit/externaldiff preference was removed. Very few users used this
135 feature, and improper configuration can actually prevent a user from editing
136 * Calling Linker methods using a skin will now output deprecation warnings.
137 * (bug 46680) "Return to" links are no longer tagged with rel="next".
138 * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
139 accesskey character is now $6 instead of $5.
140 * A new Special:Redirect page was added, providing lookup by revision ID,
141 user ID, or file name. The old Special:Filepath page was reimplemented
142 to redirect through Special:Redirect.
143 * Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9.
147 MediaWiki 1.22 requires PHP 5.3.2 or later.
149 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
150 support for them is somewhat less mature. There is experimental support for
153 The supported versions are:
155 * MySQL 5.0.2 or later
156 * PostgreSQL 8.3 or later
157 * SQLite 3.3.7 or later
158 * Oracle 9.0.1 or later
162 1.22 has several database changes since 1.21, and will not work without schema
163 updates. Note that due to changes to some very large tables like the revision
164 table, the schema update may take quite long (minutes on a medium sized site,
165 many hours on a large site).
167 If upgrading from before 1.11, and you are using a wiki as a commons
168 repository, make sure that it is updated as well. Otherwise, errors may arise
169 due to database schema changes.
171 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
172 new database fields are filled with data.
174 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
175 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
178 Don't forget to always back up your database before upgrading!
180 See the file UPGRADE for more detailed upgrade instructions.
