4 == MediaWiki 1.22 ==
5
6 THIS IS NOT A RELEASE YET
7
8 MediaWiki 1.22 is an alpha-quality branch and is not recommended for use in
9 production.
10
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.
27 * $wgJsMimeType is no longer used by core. Most usage has been removed since
28 HTML output is now exclusively HTML5.
29 * $wgDBOracleDRCP added. True enables persistent connection with DRCP on Oracle.
30
31 === New features in 1.22 ===
32 * (bug 44525) mediawiki.jqueryMsg can now parse (whitelisted) HTML elements and attributes.
33 * (bug 33454) Language::sprintfDate now has a timezone parameter, and supports
34 the "eIOPTZ" formatting characters.
35 * EditWarning: A warning is shown when an editor leaves the edit form without
36 saving (enabled by default, users can opt-out via the 'useeditwarning'
37 preference). This feature was moved from the Vector extension, and is now part
38 of core for all skins. Take care when upgrading that you don't use an older
39 version of the Vector extension as this feature may conflict.
40 * New 'mediawiki.ui' CSS module providing mw-ui-* styles for buttons and a
41 compact vertical form layout.
42 * New versions of login (Special:UserLogin) and create account
43 (Special:UserLogin/signup) forms. They are opt-in for now, controlled by
44 the $wgUseVFormUserLogin and $wgUseVFormCreateAccount settings or a 'useNew'
45 URL parameter trigger.
46 * (bug 23343) Implemented ability to apply IP blocks to the contents of X-Forwarded-For headers
47 by adding a new configuration variable $wgApplyIpBlocksToXff (disabled by default).
48 * The new hook 'APIGetPossibleErrors' to modify the list of possible errors was
49 added.
50 * (bug 25592) LogEventsList::showLogExtract() will now ignore various
51 Pager-related WebRequest parameters by default, as this is overwhelmingly
52 likely to be what was intended by users of the method. If any caller wishes
53 to use these parameters, the new param 'useRequestParams' may be set to true.
54 * mw.util.addPortletLink: Tooltip is no longer required to be plain (without
55 an accesskey in it already). As such it now rountrips. Creating a link with a
56 message as tooltip, grabbing the title attribute and using it to create
57 another portlet will work as expected.
58 * (bug 6747) {{ROOTPAGENAME}} introduced, contains the name of the topmost
59 page without namespace.
60 * BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
61 change their class name from .editsection to .mw-editsection and place them at
62 the end of the heading element instead of the beginning. Client-side code and
63 screen-scrapers will have to be adjusted to handle both cases (old HTML will
64 still be visible on cached page renders until they are purged); extensions
65 using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
66 well.
67 * (bug 45535) introduced the new 'LanguageLinks' hook for manipulating the
68 language links associated with a page before display.
69 * Chosen (http://harvesthq.github.io/chosen/) was added as module 'jquery.chosen'
70 * HTMLForm will turn multiselect checkboxes into a Chosen interface when setting cssclass 'mw-chosen'
71 * rebuildLocalisationCache learned --lang option. Let you rebuild l10n caches
72 of the specified languages instead of all of them.
73 * New GetNewMessagesAlert hook allowing extensions to disable or modify the new
74 messages alert
75 * New wgUserNewMsgRevisionId JS global for logged in users. This will be null
76 if the user has no new talk page messages. Otherwise it will be set to the
77 revision ID of the oldest new talk page message. This will allow gadgets and
78 extensions to create their own new message alerts on the client side.
79 * mediawiki.log: Added log.warn wrapper (uses console.warn and console.trace).
80 * mediawiki.log: Implemented log.deprecate. This method defines a property and
81 uses ES5 getter/setter to emit a warning when they are used.
82 * $wgCascadingRestrictionLevels was added, allowing one to specify restriction levels
83 which can be cascading (previously 'sysop' was hard-coded as the only one).
84 * XHTML5 support has been improved. If you set $wgMimeType = 'application/xhtml+xml'
85 MediaWiki will try outputting markup acording to XHTML5 rules.
86 * New hook 'TitleSquidURLs' for manipulating the list of URLs to be purged from
87 HTTP caches when a page is changed.
88 * Changed the patrolling system to always show the link for patrolling in case the
89 current revision is patrollable. This also removed the usage of the rcid URI parameters.
90 * Oracle DB backend now supports Database Resident Connection Pooling (DRCP).
91 Can be enabled by setting $wgDBOracleDRCP=true.
92 Requires Oracle DB 11gR1 or above, enabled DRCP inside the DB itself and a
93 propper connect string.
94 More about DRCP can be found at:
95 http://www.oracle-base.com/articles/11g/database-resident-connection-pool-11gr1.php
96
97 === Bug fixes in 1.22 ===
98 * Disable Special:PasswordReset when $wgEnableEmail is false. Previously one
99 could still navigate to the page by entering the URL directly.
100 * (bug 47138) Fixed a fatal error when a blocked user tries to automatically
101 create an account on login due external authentication in some circumstances.
102 * (bug 23393) HTML <hN> headings containing line breaks are now handled
103 correctly.
104 * (bug 45803) Whitespace within == Headline == syntax and within <hN> headings
105 is now non-significant and not preserved in the HTML output.
106 * (bug 47218) Special:BlockList now handles correctly user names with spaces
107 when passed as subpage.
108 * Pager's properly validate which fields are allowed to be sorted on.
109 * mw.util.tooltipAccessKeyRegexp: The regex now matches "option-" as well.
110 Support for Mac "option" was added in 1.16, but the regex was never updated.
111 * (bug 46768) Usernames of blocking users now display correctly, even if numeric.
112 * (bug 39590) {{PAGESIZE}} for the current page and self-transclusions now
113 show the most up to date result always instead of being a revision behind.
114 * A bias in wfRandomString() toward digits 1-7 has been corrected. Generated
115 strings will now start with digits 0 and 8-f as often as they should.
116 * (bug 45371) Removed Parser_LinkHooks and CoreLinkFunctions classes.
117 * (bug 41545) Allow <kbd>, <samp>, and <var> to be nested like allowed in html.
118 * PLURAL magic word no longer causes a PHP notice when no matching form exists.
119 * (bug 36641) Patrol page links no longer show on non-existent revisions.
120 * (bug 35810) Pages not linked from Special:RecentChanges or Special:NewPages
121 are patrollable now.
122 * (bug 30213) JavaScript for search suggestions is now disabled when the API
123 is disabled, and AJAX patrolling and watching are now disabled when use of
124 the write API is not allowed.
125 * (bug 48294) API: Fix chunk upload async mode.
126
127 === API changes in 1.22 ===
128 * (bug 46626) xmldoublequote parameter was removed. Because of a bug, the
129 parameter has had no effect since MediaWiki 1.16, and so its removal is
130 unlikely to impact existing clients.
131 * (bug 47216) action=query&meta=siteinfo&siprop=skins will now indicate which
132 skin is the default and which are unusable (e.g. listed in $wgSkipSkins).
133 * (bug 25325) Added support for wlshow filtering (bots/anon/minor/patrolled)
134 to action=feedwatchlist.
135 * WDDX formatted output will actually be formatted (and normal output will no
136 longer be), and will no longer choke on booleans.
137 * action=opensearch no longer silently ignores the format parameter.
138 * action=opensearch now supports format=jsonfm.
139 * list=usercontribs&ucprop=ids will now include the parent revision id.
140 * BREAKING CHANGE: action=parse no longer returns all langlinks for the page
141 with prop=langlinks by default. The new effectivelanglinks parameter will
142 request that the LanguageLinks hook be called to determine the effective
143 language links.
144 * BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
145 apply the new LanguageLinks hook, and thus only consider language links
146 stored in the database.
147 * (bug 47219) Allow specifying change type of Wikipedia feed items
148 * prop=imageinfo now allows setting iiurlheight without setting iiurlwidth
149 * prop=info now adds the content model and page language of the title.
150 * New upload log entries will now contain information on the relavent
151 image (sha1 and timestamp).
152
153 === Languages updated in 1.22===
154
155 MediaWiki supports over 350 languages. Many localisations are updated
156 regularly. Below only new and removed languages are listed, as well as
157 changes to languages because of Bugzilla reports.
158
159 * (bug 46751) Made Buryat (Russia) (буряад) (bxr) fallback to Russian.
160
161 === Other changes in 1.22 ===
162 * redirect.php was removed. It was unused.
163 * ClickTracking integration was dropped from the mediaWiki.user.bucket
164 JavaScript function. The 'tracked' option is now ignored.
165 * BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
166 were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
167 LegacyTemplate classes that supported them were removed as well and are now a
168 part of the Nostalgia extension.
169 * Event namespace used by jquery.makeCollapsible has been changed from
170 'mw-collapse' to 'mw-collapsible' for consistency with the module name.
171 * BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
172 with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
173 $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
174 use AuthPlugin for external authentication/authorization needs.
175 * The Quickbar feature of the legacy skin model and the last remnants of it
176 throughout the code base have been removed.
177 * Externaledit/externaldiff preference was removed. Very few users used this
178 feature, and improper configuration can actually prevent a user from editing
179 * Calling Linker methods using a skin will now output deprecation warnings.
180 * (bug 46680) "Return to" links are no longer tagged with rel="next".
181 * BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
182 accesskey character is now $6 instead of $5.
183 * HipHop compiler (hphpc) support was removed. HipHop VM support (hhvm) was
184 added.
185 * A new Special:Redirect page was added, providing lookup by revision ID,
186 user ID, or file name. The old Special:Filepath page was reimplemented
187 to redirect through Special:Redirect.
188 * Monobook: Removed the old conditional stylesheets for Opera 6, 7 and 9.
189 * Support for XHTML 1.0 has been removed. MediaWiki now only outputs (X)HTML5.
190 * wikibits: User-agent related globals have been deprecated. The following
191 properties now default to false and emit mw.log.warn: is_gecko, is_chrome_mac,
192 is_chrome, webkit_version, is_safari_win, is_safari, webkit_match, is_ff2,
193 ff2_bugs, is_ff2_win, is_ff2_x11, opera95_bugs, opera7_bugs, opera6_bugs,
194 is_opera_95, is_opera_preseven, is_opera, and ie6_bugs.
195
196 == Compatibility ==
197
198 MediaWiki 1.22 requires PHP 5.3.2 or later.
199
200 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
201 support for them is somewhat less mature. There is experimental support for
202 Oracle.
203
204 The supported versions are:
205
206 * MySQL 5.0.2 or later
207 * PostgreSQL 8.3 or later
208 * SQLite 3.3.7 or later
209 * Oracle 9.0.1 or later
210
211 == Upgrading ==
212
213 1.22 has several database changes since 1.21, and will not work without schema
214 updates. Note that due to changes to some very large tables like the revision
215 table, the schema update may take quite long (minutes on a medium sized site,
216 many hours on a large site).
217
218 If upgrading from before 1.11, and you are using a wiki as a commons
219 repository, make sure that it is updated as well. Otherwise, errors may arise
220 due to database schema changes.
221
222 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
223 new database fields are filled with data.
224
225 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
226 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
227 with MediaWiki 1.21.
228
229 Don't forget to always back up your database before upgrading!
230
231 See the file UPGRADE for more detailed upgrade instructions.
232
233 For notes on 1.21.x and older releases, see HISTORY.
