10 == Upgrading notes for 1.37 ==
11 Don't forget to always back up your database before upgrading!
13 See the file UPGRADE for more detailed per-version upgrade instructions from the
14 oldest supported upgrading version, MediaWiki 1.27.
16 Some specific notes for MediaWiki 1.37 upgrades are below:
19 For notes on 1.36.x and older releases, see HISTORY.
21 === Configuration changes for system administrators in 1.37 ===
24 ==== New configuration ====
25 * $wgBrowserFormatDetection - This setting allows the enabling or disabling
26 of automatic detection of possible phone numbers in a webpage in Safari on iOS.
29 ==== Changed configuration ====
30 * $wgContentHandlerTextFallback - This setting, which defines how to
31 react if a plain text version of a non-text Content object is
32 requested using ContentHandler::getContentText(), is deprecated.
33 * $wgActions was reworked to support injecting dependencies into
34 Action subclasses. Previously, $wgActions was an array where the
35 keys were the names of actions, and the values had the following
36 impacts (for a given key 'Foo')
37 - `true`: use the class 'FooAction' unless for a specific page
38 WikiPage::getActionOverrides() wants to override that action
39 - a string: use the class with that name, and do not allow overriding
41 - `false`: the action is disabled
42 - a callable: use the Action instance returned by invoking that
43 callback, and do not allow overriding on a per-page basis
44 - an object: use that specific Action instance, and do not allow
45 overriding on a per-page basis.
46 As part of T253078, values can now be arrays that are not callables,
47 which are treated as ObjectFactory specs, allowing for services to
48 be injected. Additionally, the distinction between values that allow
49 per-page overrides and those that do not was removed - all actions
50 can now be overridden on a per-page basis using
51 WikiPage::getActionOverrides().
52 * $wgShellboxUrl is deprecated, use $wgShellboxUrls as a mapping of
53 service => URL instead.
54 * $wgIncludejQueryMigrate Default value for this configuration has changed
55 from true to false. This may break gadgets that depended on methods removed
56 in jQuery 3. See T280944 for more information.
59 ==== Removed configuration ====
60 * $wgLegacyJavaScriptGlobals, deprecated in 1.36.
61 * $wgShowDBErrorBacktrace, deprecated and non-functional since 1.32.
62 * $wgShowSQLErrors, deprecated and non-functional since 1.32.

64 at most 10 objects in its LRU-cache.

204 RevisionRecord instead:
205 - PageUpdater::doCreate()
206 - PageUpdater::doModify()
207 - Parser::statelessFetchTemplate()
208 - WikiPage::doEditContent()
209 The ParserOptions `templateCallback` option is a callback that is called

211 'revision' key to that array used to be a Revision object and was used if
212 no 'revision-record' was returned - it is now ignored.
213 * Previously, the classes RevisionTestModifyableContent and
214 RevisionTestModifyableContentHandler were loaded for use in tests, but
215 were only used within the tests for the since-removed Revision class. This

307 This is so that we can use the default PHPUnit entry point (T90875).
308 * The PHPUNIT_REUSE_DB / --reuse-db option was removed from the phpunit.php
309 runner. It had been broken for at least three years already. The original use

331 $wgUser but was deprecated since 1.36.
332 * ParserOptions::newCanonical() no longer supports the first parameter being
333 null (or omitted entirely), which would fallback to the global $wgUser but

354 supported. Use MergeHistoryFactory instead. MergeHistory::checkPermissions,
355 deprecated since 1.36, was removed.
356 * Skin::generateDebugHTML(), deprecated since 1.35, was removed. Call
357 MWDebug::getHTMLDebugLog() directly.
358 * The ApiTestCase class no longer interacts with the global $wgUser.
359 Previously, the global variable was set at the start of each test, and in
360 ApiTestCase::doApiRequest() if a performer was specified $wgUser was
361 updated to match, and if no performer was specified $wgUser was used
362 instead. Now, $wgUser is not updated, and if no performer is specified
363 the reusable TestUser object for the sysop is relied on. Extensions
364 or skins that rely on the global $wgUser variable (which has been
365 deprecated since 1.35) should instead retrieve the acting user from the
366 relevant context source.

378 of User as $audience parameter.
379 - A number of methods now accept UserIdentity instead of User parameter.
380 - ::localUserFromCentralId method now returns UserIdentity and not necessarily
382 All extensions that extend this class or use this method were updated to be
383 ready to the new behavior.
384 * WatchedItemStoreInterface::enqueueWatchlistExpiryJob, deprecated since 1.36,
386 * ResultWrapper is now abstract. It cannot be directly constructed (T286694).

410 * Article::getContentObject, deprecated since 1.32, was removed.
