1 Security reminder: MediaWiki does not require PHP's register_globals. If you
2 have it on, turn it '''off''' if you can.
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.
18 * $wgCascadingRestrictionLevels was added.
19 * ftps, ssh, sftp, xmpp, sip, sips, tel, sms, bitcoin, magnet, urn, and geo
20 have been whitelisted inside of $wgUrlProtocols.
21 * $wgDocType and $wgDTD have been removed and are no longer used for the DOCTYPE.
22 * $wgHtml5 is no longer used by core. Setting it to false will no longer disable HTML5.
23 It is still set to true for extension compatibility but doing so in extensions is deprecated.
24 * $wgXhtmlDefaultNamespace is no longer used by core. Setting it will no longer change the
25 xmlns used by MediaWiki. Reliance on this variable by extensions is deprecated.
26 * $wgHandheldStyle was removed.
28 === New features in 1.22 ===
29 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
30 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
31 the "eIOPTZ" formatting characters.
32 * EditWarning: A warning is shown when an editor leaves the edit form without
33 saving (enabled by default, users can opt-out via the 'useeditwarning'
34 preference). This feature was moved from the Vector extension, and is now part
35 of core for all skins. Take care when upgrading that you don't use an older
36 version of the Vector extension as this feature may conflict.
37 * New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
38 compact vertical form layout.
39 * New versions of login (Special:UserLogin) and create account
40 (Special:UserLogin/signup) forms. They are opt-in for now, controlled by
41 the $wgUseVFormUserLogin and $wgUseVFormCreateAccount settings or a 'useNew'
42 URL parameter trigger.
43 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
44 by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
45 * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
47 * (bug 25592) LogEventsList::showLogExtract() will now ignore various
48 Pager-related WebRequest parameters by default, as this is overwhelmingly
49 likely to be what was intended by users of the method. If any caller wishes
50 to use these parameters, the new param 'useRequestParams' may be set to true.
51 * mw.util.addPortletLink: Tooltip is no longer required to be plain (without
52 an accesskey in it already). As such it now rountrips. Creating a link with a
53 message as tooltip, grabbing the title attribute and using it to create
54 another portlet will work as expected.
55 * (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
56 page without namespace.
57 * BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
58 change their class name from .editsection to .mw-editsection and place them at
59 the end of the heading element instead of the beginning. Client-side code and
60 screen-scrapers will have to be adjusted to handle both cases (old HTML will
61 still be visible on cached page renders until they are purged); extensions
62 using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
64 * (bug 45535) introduced the new 'LanguageLinks' hook for manipulating the
65 language links associated with a page before display.
66 * Chosen (http://harvesthq.github.io/chosen/) was added as module 'jquery.chosen'
67 * HTMLForm will turn multiselect checkboxes into a Chosen interface when setting cssclass 'mw-chosen'
68 * rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches
69 of the specified languages instead of all of them.
70 * New GetNewMessagesAlert hook allowing extensions to disable or modify the new
72 * New wgUserNewMsgRevisionId JS global for logged in users. This will be null
73 if the user has no new talk page messages. Otherwise it will be set to the
74 revision ID of the oldest new talk page message. This will allow gadgets and
75 extensions to create their own new message alerts on the client side.
76 * mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace).
77 * mediawiki.log: Implemented log.deprecate. This method defines a property and
78 uses ES5 getter/setter to emit a warning when they are used.
79 * $wgCascadingRestrictionLevels was added, allowing one to specify restriction levels
80 which can be cascading (previously 'sysop' was hard-coded as the only one).
81 * XHTML5 support has been improved. If you set $wgMimeType = 'application/xhtml+xml'
82 MediaWiki will try outputting markup acording to XHTML5 rules.
84 === Bug fixes in 1.22 ===
85 * Disable Special:PasswordReset when $wgEnableEmail is false. Previously one
86 could still navigate to the page by entering the URL directly.
87 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
88 create an account on login due external authentication in some circumstances.
89 * (bug 23393) HTML <hN> headings containing line breaks are now handled
91 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
92 is now non-significant and not preserved in the HTML output.
93 * (bug 47218) Special:BlockList now handles correctly user names with spaces
94 when passed as subpage.
95 * Pager's properly validate which fields are allowed to be sorted on.
96 * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
97 Support for Mac "option" was added in 1.16, but the regex was never updated.
98 * (bug 46768) Usernames of blocking users now display correctly, even if numeric.
99 * (bug 39590) {{PAGESIZE}} for the current page and self-transclusions now
100 show the most up to date result always instead of being a revision behind.
101 * A bias in wfRandomString() toward digits 1-7 has been corrected. Generated
102 strings will now start with digits 0 and 8-f as often as they should.
103 * (bug 45371) Removed Parser_LinkHooks and CoreLinkFunctions classes.
104 * (bug 41545) Allow <kbd>, <samp>, and <var> to be nested like allowed in html.
106 === API changes in 1.22 ===
107 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
108 parameter has had no effect since MediaWiki 1.16, and so its removal is
109 unlikely to impact existing clients.
110 * (bug 47216) action=query&meta=siteinfo&siprop=skins will now indicate which
111 skin is the default and which are unusable (e.g. listed in $wgSkipSkins).
112 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
113 to action=feedwatchlist.
114 * WDDX formatted output will actually be formatted (and normal output will no
115 longer be), and will no longer choke on booleans.
116 * action=opensearch no longer silently ignores the format parameter.
117 * action=opensearch now supports format=jsonfm.
118 * list=usercontribs&ucprop=ids will now include the parent revision id.
119 * BREAKING CHANGE: action=parse no longer returns all langlinks for the page
120 with prop=langlinks by default. The new effectivelanglinks parameter will
121 request that the LanguageLinks hook be called to determine the effective
123 * BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
124 apply the new LanguageLinks hook, and thus only consider language links
125 stored in the database.
126 * (bug 47219) Allow specifying change type of Wikipedia feed items
127 * prop=imageinfo now allows setting iiurlheight without setting iiurlwidth
128 * prop=info now adds the content model of the title.
129 * New upload log entries will now contain information on the relavent
130 image (sha1 and timestamp).
132 === Languages updated in 1.22===
134 MediaWiki supports over 350 languages. Many localisations are updated
135 regularly. Below only new and removed languages are listed, as well as
136 changes to languages because of Bugzilla reports.
138 * (bug 46751) Made Buryat (Russia) (буряад) (bxr) fallback to Russian.
140 === Other changes in 1.22 ===
141 * redirect.php was removed. It was unused.
142 * ClickTracking integration was dropped from the mediaWiki.user.bucket
143 JavaScript function. The 'tracked' option is now ignored.
144 * BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
145 were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
146 LegacyTemplate classes that supported them were removed as well and are now a
147 part of the Nostalgia extension.
148 * Event namespace used by jquery.makeCollapsible has been changed from
149 'mw-collapse' to 'mw-collapsible' for consistency with the module name.
150 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
151 with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
152 $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
153 use AuthPlugin for external authentication/authorization needs.
154 * The Quickbar feature of the legacy skin model and the last remnants of it
155 throughout the code base have been removed.
156 * Externaledit/externaldiff preference was removed. Very few users used this
157 feature, and improper configuration can actually prevent a user from editing
158 * Calling Linker methods using a skin will now output deprecation warnings.
159 * (bug 46680) "Return to" links are no longer tagged with rel="next".
160 * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
161 accesskey character is now $6 instead of $5.
162 * HipHop compiler (hphpc) support was removed. HipHop VM support (hhvm) was
164 * A new Special:Redirect page was added, providing lookup by revision ID,
165 user ID, or file name. The old Special:Filepath page was reimplemented
166 to redirect through Special:Redirect.
167 * Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9.
168 * Support for XHTML 1.0 has been removed. MediaWiki now only outputs (X)HTML5.
172 MediaWiki 1.22 requires PHP 5.3.2 or later.
174 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
175 support for them is somewhat less mature. There is experimental support for
178 The supported versions are:
180 * MySQL 5.0.2 or later
181 * PostgreSQL 8.3 or later
182 * SQLite 3.3.7 or later
183 * Oracle 9.0.1 or later
187 1.22 has several database changes since 1.21, and will not work without schema
188 updates. Note that due to changes to some very large tables like the revision
189 table, the schema update may take quite long (minutes on a medium sized site,
190 many hours on a large site).
192 If upgrading from before 1.11, and you are using a wiki as a commons
193 repository, make sure that it is updated as well. Otherwise, errors may arise
194 due to database schema changes.
196 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
197 new database fields are filled with data.
199 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
200 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
203 Don't forget to always back up your database before upgrading!
205 See the file UPGRADE for more detailed upgrade instructions.
