Make Special:UserLogin form use mw-ui-checkbox
[lhc/web/wiklou.git] / RELEASE-NOTES-1.24
1 Security reminder: If you have PHP's register_globals option set, you must
2 turn it off. MediaWiki will no longer work with it enabled.

4 == MediaWiki 1.24 ==
5
6 THIS IS NOT A RELEASE YET
7
8 MediaWiki 1.24 is an alpha-quality branch and is not recommended for use in
9 production.
10
11 === Configuration changes in 1.24 ===
12 * MediaWiki will no longer run if register_globals is enabled. It has been
13 deprecated for 5 years now, and was removed in PHP 5.4. For more information
14 about why, see <https://www.mediawiki.org/wiki/register_globals>.
15 * MediaWiki now requires PHP's iconv extension. openSUSE users may need to
16 install the php5-iconv package. Users of other systems may need to add
17 extension=iconv.so to php.ini or recompile PHP without --without-iconv.
18 * MediaWiki will no longer function if magic quotes are enabled. It has
19 been deprecated for 5 years now, and was removed in PHP 5.4.
20 * The server's canonical hostname is available as $wgServerName, which is
21 exposed in both mw.config and ApiQuerySiteInfo.
22 * Introduced $wgPagePropsHaveSortkey as a backwards-compatibility switch,
23 for using the old schema of the page_props table, in case the respective
24 schema update was not applied.
25 * $wgSearchEverythingOnlyLoggedIn was removed as the 'searcheverything'
26 user option was removed. Use $wgNamespacesToBeSearchedDefault instead or
27 if you used to have $wgDefaultUserOptions['searcheverything'] = 1.
28 * $wgMasterWaitTimeout has been deprecated.
29 * $wgDBClusterTimeout has been removed.
30 * $wgProxyKey has been removed. It is no longer used by MediaWiki core.
31 Ensure $wgSecretKey is set in LocalSettings.php.
32 * $wgExtraInterlanguageLinkPrefixes is a new configuration variable that
33 contains an array of interwiki prefixes that should be treated as language
34 prefixes (i.e. turned into interlanguage links when $wgInterwikiMagic is set
35 to true).
36 * $wgParserTestRemote has been removed.
37 * $wgCountTotalSearchHits has been removed. If you're concerned about efficiency
38 of search, you should use something like CirrusSearch instead of built in
39 search.
40 * Users in the 'sysop' group have access to Special:MergeHistory by default.
41 * $wgFileStore was removed after having been deprecated in 1.17. Alternative
42 configurations are $wgDeletedDirectory and $wgHashedUploadDirectory.
43 * The deprecated $wgUseCommaCount variable has been removed.
44 * $wgEnableSorbs and $wgSorbsUrl have been removed.
45 * The UserCryptPassword and UserComparePassword hooks are no longer called. Any extensions
46 using them must be updated to use the Password Hashing API.
47 * $wgCompiledFiles has been removed.
48 * $wgSortSpecialPages was removed, the listing on Special:SpecialPages is
49 now always sorted.
50 * Users must be able to edit a page to be able to delete it.
51 * $wgHTCPMulticastAddress, $wgHTCPMulticastRouting and $wgHTCPPort were removed.
52 * $wgRC2UDPAddress, $wgRC2UDPInterwikiPrefix, $wgRC2UDPOmitBots, $wgRC2UDPPort
53 and $wgRC2UDPPrefix have been removed.
54
55 === New features in 1.24 ===
56 * Added a new hook, "WhatLinksHereProps", to allow extensions to annotate
57 WhatLinksHere entries.
58 * Added a new hook, "ContentGetParserOutput", to customize parser output for
59 a given content object.
60 * Deprecated the hook "ShowRawCssJs", use "ContentGetParserOutput" instead.
61 * HTMLForm's HTMLTextField now supports the 'url' type.
62 * HTMLForm fields may now be dynamically hidden based on the values of other
63 fields in the form.
64 * HTMLForm now supports multiple copies of an input field or set of input
65 fields, e.g. the form may request "one or more usernames" without having to
66 have the user enter delimited list of names into a text field.
67 * Added a new hook, "SidebarBeforeOutput", to allow to edit the structure of
68 the sidebar just before its display.
69 * (bug 49156) Added the mediawiki.cookie ResourceLoader module, which wraps
70 jquery.cookie so that getting/setting a cookie is syntactically and
71 functionally similar to using the WebRequest::getCookie() and
72 WebResponse::setcookie() methods.
73 * (bug 44740) jQuery upgraded from 1.8.3 to 1.11.1. A new configuration option,
74 $wgIncludejQueryMigrate, also loads the jQuery Migrate hack to let extensions
75 and gadgets use the long-deprecated functions that were removed in jQuery 1.9.
76 This option is turned off by default, and will be removed in MediaWiki 1.25.
77 * (bug 47076) jQuery UI upgraded from 1.8.24 to 1.9.2.
78 * Changes to content typography (fonts, etc.). See
79 https://www.mediawiki.org/wiki/Typography_refresh for further information.
80 * WikitextContent will now render redirects with the expected "redirect"
81 header, rather than as an ordered list. Code calling Article::viewRedirect
82 can probably be changed to no longer special-case redirects.
83 * Header font set to a serif font stack. See
84 https://www.mediawiki.org/wiki/Typography_refresh for further information.
85 * (bug 65567) Added a new hook, "BeforeHttpsRedirect", to allow cancellation of
86 the HTTP to HTTPS redirect due to forceHTTPS cookie, userRequires, etc. This
87 is only for page views, since this hook doesn't affect UserLogin, OAuth,
88 CentralAuth, etc. ATTENTION: This hook is likely to be removed soon due to
89 overall design of the system.
90 * (bug 17367) It is now possible to add pages to your watchlist from
91 Special:UnwatchedPages without reloading the special page.
92 * New methods setVolatile and isVolatile are added to PPFrame, so that
93 extensions such as Cite.php can mark that their output is volatile and
94 shouldn't be cached.
95 * (bug 52817) Advanced search options are now saved on the search page itself,
96 rather than in a dedicated pane in the preferences panel.
97 * (bug 44591) The dropdown actions menu (little triangle next to page tabs) in
98 the Vector skin has gained a label that should make it more discoverable.
99 * MWCryptHKDF added for fast, cryptographically secure random number generation
100 that won't deplete openssl's entropy pool.
101 * ResourceLoader: File modules can now provide a skip function that uses an
102 inline feature test to bypass loading of the module.
103 * (bug 20210) Special pages may now provide autocompletion of their subpage
104 names in search suggestions. Right now the only useful implementation is in
105 Special:Log, but more are to come.
106 * Special:MostLinkedTemplates is no longer limited to transclusions from the
107 Template namespace.
108 * Skins can now use 'remoteSkinPath' when defining ResourceLoader modules.
109 This works the same as 'remoteExtPath' but is relative to the skins/ folder
110 instead of the extensions/ folder.
111 * Added the json2.js polyfill for the ES5 JSON.stringify and JSON.parse methods.
112 Exposed as module "json" with a skip function to optimise loading.
113 * Extensions and skins may now use 'namemsg' in $wgExtensionCredits in addition
114 to 'name', to allow for the name to be localizable. 'name' should still be
115 specified for backwards-compatibility and to define the path Special:Version
116 uses to find extension license information.
117 * Browser tests are now included to verify basic wiki functionality in developer
118 environments. For details on running tests, see tests/browser/README.mediawiki.
119 * Upgrade jStorage to v0.4.10.
120 * {{!}} is now a magic word that produces the | character. This removes the need
121 for Template:! for purposes such as passing pipes inside of parameters.
122 * (bug 20790) The block log snippet on Special:Contributions and while
123 editing user and user talk pages now works for IP range blocks.
124 * (bug 9360) Added ability to change the page language for MediaWiki pages using
125 Special:PageLanguage. All pages are set to wiki language by default.
126 The feature needs to be enabled with $wgPageLanguageUseDB=true and
127 permission needs to be set for 'pagelang'.
128 * Upgrade Moment.js to v2.7.0.
129 * (bug 67042) Added support for the HTML5 <rtc> tag for East Asian typography.
130 * Upgrade Sinon.JS to 1.10.3.
131 * Added the es5-shim polyfill for older or non-compliant javascript engines.
132 * Upgrade jQuery Cookie to v1.3.1.
133 * (bug 20476) Add a "viewsuppressed" user right to be able to view
134 suppressed content but not suppress it ("suppressrevision" right).
135 * (bug 66440) The MediaWiki web installer will now allow you to choose the skins
136 to enable (from the ones included in download tarball) and decide which one
137 should be the default.
138 * (bug 68085, 68802) Links like [[localInterwikiPrefix:languageCode:pageTitle]],
139 where localInterwikiPrefix is a member of the $wgLocalInterwikis array, will
140 no longer be displayed in the sidebar when $wgInterwikiMagic is true. In a
141 similar way, links like [[localInterwikiPrefix:File:Image.png]] and
142 [[localInterwikiPrefix:Category:Hello]] will now render as regular links, and
143 will not include the file or add the page to the category.
144 * New special page, MyLanguages, to redirect users to subpages with localised
145 versions of a page. (Integrated from Extension:Translate)
146 * MediaWiki now supports multiple password types, including bcrypt and PBKDF2.
147 The default type can be changed with $wgPasswordDefault and the type
148 configurations can be changed with $wgPasswordConfig.
149 * Skins can now define custom styles for default ResourceLoader modules using
150 the $wgResourceModuleSkinStyles global. See the Vector skin for examples.
151 * (bug 4488) There is now a preference to watch pages where the user has
152 rollbacked an edit by default.
153 * (bug 15484) Users will now be redirected to the login page when they need to
154 log in, rather than being shown a page asking them to log in and having to click
155 another link to actually get to the login page.
156 * A JSONContent and JSONContentHandler were added for extensions to extend.
157
158 === Bug fixes in 1.24 ===
159 * (bug 50572) MediaWiki:Blockip should support gender
160 * (bug 49116) Footer copyright notice is now always displayed in user language
161 rather than content language (same as copyright notice for editing interface).
162 * (bug 62258) A bug was fixed in File::getUnscaledThumb when a height
163 restriction was present in the parameters. Images with both the "frame"
164 option and a size specification set will now always ignore the provided
165 size and display an unscaled image, as the documentation has always
166 claimed it would.
167 * (bug 39035) Improved Vector skin performance by removing collapsibleNav,
168 which used to collapse some sidebar elements by default.
169 This removes -list id suffixes like p-lang-list: instead of using things like
170 #p-lang-list, you can do #p-lang .body ul.
171 * (bug 890) Links in Special:RecentChanges and Special:Watchlist no longer
172 follow redirects to their target pages.
173 * Parser now dies early if called recursively, instead of producing subtle bugs.
174 * (bug 14323) Redirect pages, when viewed with redirect=no, no longer hide the
175 remaining page content.
176 * (bug 52587) Maintenance script deleteBatch.php no longer follows redirects
177 in the file namespace and delete the file on the target page. It will still
178 however delete the redirect page.
179 * (bug 22683) {{msgnw:}} and other uses of PPFrame::RECOVER_ORIG will correctly
180 recover the original code of extension tags.
181 * (bug 65757) MSSQL: Update script drops unnamed constraints to be prepared
182 for future updates. Because it's doing so heuristically, it may fail or drop
183 wrong constraints.
184 * (bug 67870) wfShellExec() cuts off stdout at multiples of 8192 bytes.
185 * $wgRunJobsAsync now works with private wikis (e.g. read requires login).
186 * (bugs 57238, 65206) Blank pages can now be directly created.
187
188 === Web API changes in 1.24 ===
189 * action=parse API now supports prop=modules, which provides the list of
190 ResourceLoader modules that should be used to enhance the parsed content.
191 * action=query&meta=siteinfo&siprop=interwikimap returns a new "protorel"
192 field which is true iff protocol-relative urls can be used to access
193 a particular interwiki map entry.
194 * ApiQueryLogEvents now provides logpage, which is the page ID from the
195 logging table, if ids are requested and the user has the permissions.
196 * action=edit now requires that appendtext, prependtext, or section=new be used
197 when using the 'redirect' parameter, to prevent clients accidentally
198 overwriting the target page with the content of the redirect.
199 * action=logevents will now return an error if both letitle and leprefix are
200 specified.
201 * action=logevents has a new parameter, lenamespace, to allow filtering by
202 namespace.
203 * action=expandtemplates has a new parameter, prop, and a new output format.
204 The old format is still used if prop isn't provided, but this is deprecated.
205 * meta=userinfo can now return the count of unread pages on the watchlist.
206 * list=watchlist can now filter by unread status.
207 * The deprecated action=parse&prop=languageshtml has been removed.
208 * (bug 48071) action=setnotificationtimestamp no longer throws PHP or database
209 errors when no pages are given.
210 * (bug 60734) Actions that use ApiPageSet (e.g. purge, watch,
211 setnotificationtimestamp) will now include continuation information when
212 using a generator.
213 * $wgAPIModules (and the related $wgAPIFormatModules, $wgAPIMetaModules,
214 $wgAPIPropModules, and $wgAPIListModules settings) now allow API modules
215 to be specified using a "module spec" array instead of a plain class name.
216 A "module spec" is an associative array containing at least the 'class' key
217 for the module's class, and optionally a 'factory' key for the factory function
218 to use for the module. This is intended for extensions that want control over
219 the instantiation of their API modules, to allow for proper dependency
220 injection.
221 * Removed 'props' and 'errors' from action=paraminfo, as they have extremely
222 limited use and are generally inaccurate, unmaintained, and impossible to
223 properly maintain. Also removed the corresponding methods from ApiBase and
224 the 'APIGetPossibleErrors' and 'APIGetResultProperties' hooks.
225
226 === Languages updated in 1.24 ===
227
228 MediaWiki supports over 350 languages. Many localisations are updated
229 regularly. Below only new and removed languages are listed, as well as
230 changes to languages because of Bugzilla reports.
231
232 === Other changes in 1.24 ===
233 * The deprecated jquery.delayedBind ResourceLoader module was removed.
234 * The deprecated function mw.util.toggleToc was removed.
235 * The Special:Search hooks SpecialSearchGo and SpecialSearchResultsAppend
236 were removed as they were unused.
237 * (bug 65477) User::pingLimiter() now has an additional profile point varying
238 by action being used.
239 * mediawiki.util.$content no longer supports old versions of the Vector,
240 Monobook, Modern and CologneBlue skins that don't yet implement the "mw-body"
241 and/or "mw-body-primary" class name in their html.
242 * Added pp_sortkey column to page_props table, so pages can be efficiently
243 queried and sorted by property value (bug 58032).
244 See $wgPagePropsHaveSortkey if you want to postpone the schema change.
245 * BREAKING CHANGE: All four built-in MediaWiki skins (Vector, MonoBook, Modern
246 and Cologne Blue) were moved out of MediaWiki core to their own respective
247 repositories. They will be installed with the release tarball, but you must
248 install them separately if installing MediaWiki from source code. A warning
249 message displayed until you do it should guide you through the process. See
250 also <https://www.mediawiki.org/wiki/Manual:Skin_configuration>.
251 * BREAKING CHANGE: Skins built for MediaWiki 1.15 and earlier that do not use
252 the "headelement" template key are no longer supported. Setting
253 $useHeadElement = false; is no longer supported and will not cause old keys
254 like "headlinks", "skinnameclass", etc. to be defined.
255 * The deprecated 'SpecialVersionExtensionTypes' hook was removed.
256 * (bug 63891) Add 'X-Robots-Tag: noindex' header in action=render pages.
257 * SpecialPage no longer supports the syntax for invoking wfSpecial*() functions.
258 Special pages should subclass SpecialPage and implement the execute() method.
259 * (bug 63755) The deprecated constants RC_MOVE and RC_MOVE_OVER_REDIRECT were
260 removed.
261 * Special:MostLinkedTemplates has been renamed to Special:MostTranscludedPages.
262 * The skin autodiscovery mechanism has been deprecated and will be removed in
263 MediaWiki 1.25. See https://www.mediawiki.org/wiki/Manual:Skin_autodiscovery
264 for migration guide for creators and users of custom skins that relied on it.
265 * ResourceLoaderFileModule#getAllStyleFiles now returns all style files and all
266 skin style files used by the module.
267 * Removed getLang() from IContextSource and subclasses. (deprecated since 1.19)
268 * Removed setLang() from subclasses of IContextSource. (deprecated since 1.19)
269 * Removed WebRequest::escapeAppendQuery(). (deprecated since 1.20)
270 * Removed info(), purge(), revert() and rollback() from the Article class; they
271 have since become subclasses of the Action class. (deprecated since 1.19)
272 * SearchEngineReplacePrefixesComplete hook was removed.
273 * The "jquery.json" module has been deprecated. Use the "json" module instead.

279 * Removed ApiBase::createContext(). (deprecated since 1.19)
280 * BREAKING CHANGE: The undocumented Special{$this->getName()}BeforeFormDisplay
281 set of hooks has been removed and replaced by a single new hook
282 SpecialPageBeforeFormDisplay.
283 * (bug 65781) Removed block warning on included {{Special:Contributions}}
284 * Removed Skin::makeGlobalVariablesScript. (deprecated since 1.19)
285 * Removed MWNamespace::isMain(). (deprecated since 1.19)
286 * Removed Preferences::loadOldSearchNs(). (deprecated since 1.19)
287 * Removed OutputPage::getStatusMessage(). (deprecated since 1.18)
288 * Removed OutputPage::isUserJsAllowed(). (deprecated since 1.18)

292 * Removed Title::escapeLocalURL(). (deprecated since 1.19)
293 * Removed Title::escapeFullURL(). (deprecated since 1.19)
294 * Removed User::isValidEmailAddr(). (deprecated since 1.18)
295 * Removed Title::getEscapedText(). (deprecated since 1.19)

297 * Removed WikiPage::isBigDeletion(). (deprecated since 1.19)
298 * Removed MWInit class which contained functions related to a now discontinued
299 PHP compiler called hphpc. (deprecated since 1.22)
300 * ApiResult::enableSizeCheck() and disableSizeCheck() are now obsolete.
301 * Removed ResourceLoaderGetStartupModules hook. (deprecated since 1.23)
302 * Removed getFormFields(), onSubmit() and onSuccess() from FormlessAction, as
303 these were meant specifically for FormAction instead.
304 * Removed Action::execute().
305 * Removed AjaxAddScript which has been obsolete since ResourceLoader and
306 is unused by any modern extension.
307 * Removed maintenance/nextJobDB.php; no longer in use.
308 * Removed global function wfViewPrevNext(). (deprecated since 1.19)
309 * Removed global function xmlsafe() from Export.php. (moved to OAIRepo extension)
310 * Removed Title::userCanRead(). (deprecated since 1.19)
311 * Removed maintenance script importTextFile.php. Use edit.php script instead.
312 * A _from_namespace field has been added to the templatelinks, pagelinks,
313 and filelinks tables. Run update.php to apply this change to the schema.
314 * Removed File::sha1Base36(). (deprecated since 1.19)
315 * Removed File::getPropsFromPath(). (deprecated since 1.19)
316 * Removed functions blockedPage(), noCreatePermission(), readOnlyPage() and
317 userNotLoggedInPage() from EditPage.php. (deprecated since 1.19)

319 setPreloadedText() from EditPage.php. (deprecated since 1.21)
320 * Removed global functions wfArrayLookup(), wfArrayMerge(), wfDebugDieBacktrace()
321 and wfTime(). (deprecated since 1.22)
322 * Microsoft Internet Explorer 6 is now a "grade C" browser, meaning that
323 JavaScript is no longer executed in this browser. The IEFixes script, which
324 existed purely to provide support for MSIE versions below 7 and which was
325 conditionally loaded for those browsers, was also removed.
326 * Action::checkCanExecute() no longer has a return value.
327 * Removed cleanupForIRC(), loadFromCurRow(), newFromCurRow(), notifyRC2UDP()
328 and sendToUDP() from RecentChange.php. (deprecated since 1.22)

378 == Compatibility ==
379
380 MediaWiki 1.24 requires PHP 5.3.2 or later.
381
382 MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but
383 support for them is somewhat less mature. There is experimental support for
384 Oracle and Microsoft SQL Server.
385
386 The supported versions are:
387
388 * MySQL 5.0.2 or later
389 * PostgreSQL 8.3 or later
390 * SQLite 3.3.7 or later
391 * Oracle 9.0.1 or later
392 * Microsoft SQL Server 2005 (9.00.1399)
393
394 == Upgrading ==
395
396 1.24 has several database changes since 1.23, and will not work without schema
397 updates. Note that due to changes to some very large tables like the revision
398 table, the schema update may take quite long (minutes on a medium sized site,
399 many hours on a large site).
400
401 If upgrading from before 1.11, and you are using a wiki as a commons
402 repository, make sure that it is updated as well. Otherwise, errors may arise
403 due to database schema changes.
404
405 If upgrading from before 1.7, you may want to run refreshLinks.php to ensure
406 new database fields are filled with data.
407
408 If you are upgrading from MediaWiki 1.4.x or earlier, you should upgrade to
409 1.5 first. The upgrade script maintenance/upgrade1_5.php has been removed
410 with MediaWiki 1.21.
411
412 Don't forget to always back up your database before upgrading!
413
414 See the file UPGRADE for more detailed upgrade instructions.
415
416 For notes on 1.23.x and older releases, see HISTORY.
417
418 == Online documentation ==
