 MediaWiki 1.22 is an alpha-quality branch and is not recommended for use in
 production.
 
-=== Configuration changes in 1.22 ===
-* $wgRedirectScript was removed. It was unused.
-* Removed $wgLocalMessageCacheSerialized, it is now always true.
-* $wgVectorUseIconWatch is now enabled by default.
-* $wgCascadingRestrictionLevels was added.
-* ftps, ssh, sftp, xmpp, sip, sips, tel, sms, bitcoin, magnet, urn, and geo
-  have been whitelisted inside of $wgUrlProtocols.
-* $wgDocType and $wgDTD have been removed and are no longer used for the DOCTYPE.
-* $wgHtml5 is no longer used by core. Setting it to false will no longer disable HTML5.
-  It is still set to true for extension compatibility but doing so in extensions is deprecated.
-* $wgXhtmlDefaultNamespace is no longer used by core. Setting it will no longer change the
-  xmlns used by MediaWiki. Reliance on this variable by extensions is deprecated.
-* $wgHandheldStyle was removed.
-* $wgHandheldForIPhone was removed.
-* $wgJsMimeType is no longer used by core. Most usage has been removed since
-  HTML output is now exclusively HTML5.
-* $wgDBOracleDRCP added. True enables persistent connection with DRCP on Oracle.
-* $wgLogAutopatrol added to allow disabling logging of autopatrol edits in the logging table.
-  default for $wgLogAutopatrol is true.
-* The 'edit' right no longer allows for editing a user's own CSS and JS.
-* New rights 'editmyusercss', 'editmyuserjs', 'viewmywatchlist',
-  'editmywatchlist', 'viewmyprivateinfo', 'editmyprivateinfo', and
-  'editmyoptions' restrict actions that were formerly allowed by default. They
-  have been added to the default for $wgGroupPermissions['*'].
-* The 'editprotected' right no longer allows bypassing of all page protection
-  restrictions. Any group using it for this purpose will now need to have all
-  the individual rights listed in $wgRestrictionTypes for the same effect.
-* The 'protect' and 'autoconfirmed' rights are no longer used for the default
-  page protection levels. The rights 'editprotected' and 'editsemiprotected'
-  are now used for this purpose instead.
-* (bug 40866) wgOldChangeTagsIndex removed.
-* $wgNoFollowDomainExceptions now only matches entire domains. For example,
-  an entry for 'bar.com' will still match 'foo.bar.com' but not 'foobar.com'.
-* $wgCopyUploadTimeout and $wgCopyUploadAsyncTimeout added to change the timeout times for
-  fetching the file during upload by url.
-* New key added to $wgGalleryOptions - $wgGalleryOptions['mode'] to set
-  default gallery mode.
-* New hook 'GalleryGetModes' to allow extensions to make new gallery modes.
-* The checkbox for staying in HTTPS displayed on the login form when $wgSecureLogin is
-  enabled has been removed. Instead, whether the user stays in HTTPS will be determined
-  based on the user's preferences, and whether they came from HTTPS or not.
-* $wgRC2UDPAddress, $wgRC2UDPInterwikiPrefix, $wgRC2UDPOmitBots, $wgRC2UDPPort,
-  and $wgRC2UDPPrefix configuration options have been deprecated in favor of a
-  $wgRCFeeds configuration array. $wgRCFeeds makes both the format and
-  destination of recent change notifications customizable, and allows for
-  multiple destinations to be specified.
-* (bug 53862) portal-url, currentevents-url and helppage have been removed from the
-  default Sidebar.
-* The 'vector-simplesearch' preference is now enabled by default. Previously
-  it was only enabled if the Vector extension was installed.
-* The precise format of metric datagrams produced by the UDP profiler and stats counter
-  may now be specified as $wgUDPProfilerFormatString and $wgStatsFormatString,
-  respectively.
-* (bug 54597) $wgBlockOpenProxies, $wgProxyPorts, $wgProxyScriptPath, and
-  $wgProxyMemcExpiry have been removed, along with the open proxy scanner
-  script they were added for.
-* Default value of $wgMaxShellMemory has been tripled (it's now 300 MB).
+* Breaking Changes in 1.22
+* New features in 1.22
+* Configuration changes in 1.22
+* Bug fixes in 1.22
+* API changes in 1.22
+* Languages updated in 1.22
+* Other changes in 1.22

+=== Breaking Changes in 1.22 ===
+* BREAKING CHANGE: (bug 41729) Display editsection links next to headings. Also
+  change their class name from .editsection to .mw-editsection and place them at
+  the end of the heading element instead of the beginning. Client-side code and
+  screen-scrapers will have to be adjusted to handle both cases (old HTML will
+  still be visible on cached page renders until they are purged); extensions
+  using the DoEditSectionLink or EditSectionLink hooks might need adjustments as
+  well.
+* (bug 55818) BREAKING CHANGE: Removed undocumented 'Debug' hook in wfDebug.
+  This resolves an infinite loop when using $wgDebugFunctionEntry = true.
+* BREAKING CHANGE: action=parse no longer returns all langlinks for the page
+  with prop=langlinks by default. The new effectivelanglinks parameter will
+  request that the LanguageLinks hook be called to determine the effective
+  language links.
+* BREAKING CHANGE: list=allpages, list=langbacklinks, and prop=langlinks do not
+  apply the new LanguageLinks hook, and thus only consider language links
+  stored in the database.
+* BREAKING CHANGE: Implementation of MediaWiki's JS and JSON value encoding
+  has changed:
+** MediaWiki no longer supports PHP installations in which the native JSON
+   extension is missing or disabled.
+** XmlJsCode objects can no longer be nested inside objects or arrays.
+   (For Xml::encodeJsCall(), this individually applies to each argument.)
+** The sets of characters escaped by default, along with the precise escape
+   sequences used, have changed (except for the Xml::escapeJsString()
+   function, which is now deprecated).
+* BREAKING CHANGE: The Services_JSON class has been removed. If necessary,
+  be sure to upgrade affected extensions at the same time (e.g. Collection).
+* BREAKING CHANGE: Legacy skins Simple, MySkin, Chick, Standard and Nostalgia
+  were all removed. (Nostalgia was moved to an extension.) The SkinLegacy and
+  LegacyTemplate classes that supported them were removed as well and are now a
+  part of the Nostalgia extension.
+* BREAKING CHANGE: The "ExternalAuth" authentication subsystem was removed, along
+  with its associated globals of $wgExternalAuthType, $wgExternalAuthConf,
+  $wgAutocreatePolicy and $wgAllowPrefChange. Affected users are encouraged to
+  use AuthPlugin for external authentication/authorization needs.
+* BREAKING CHANGE: mw.util.tooltipAccessKeyRegexp: The match group for the
+  accesskey character is now $6 instead of $5.
+* BREAKING CHANGE: meta keywords are no longer supported. A <meta name="keywords"
+  will no longer be output and OutputPage::addKeyword no longer exists.
+* BREAKING CHANGE: The EditSectionLink hook was removed after being
+  deprecated since MediaWiki 1.14. Use DoEditSectionLink instead.
+* (bug 50310) BREAKING CHANGE: wikibits: Drop support for mwCustomEditButtons.
+  It defaults to an empty array and emits mw.log.warn when accessed.
+* BREAKING CHANGE: Special:Disambiguations has been removed from MediaWiki core.
+  Functions related to disambiguation pages are now handled by the Disambiguator
+  extension (https://www.mediawiki.org/wiki/Extension:Disambiguator) (bug
+  35981).
+* BREAKING CHANGE: The 'mediawiki.legacy.wikiprintable' module has been removed.
+  The skins/common/wikiprintable.css file no longer exists. Return value of
+  Skin#commonPrintStylesheet is ignored. Please use the 'mediawiki.legacy.commonPrint'
+  module instead or base your skin on SkinTemplate.
+* BREAKING CHANGE: The module 'mediawiki.legacy.IEFixes' has been removed as it was
+  unused. The file skins/common/IEFixes.js remains but is only used by wikibits.
+  The file never contained any re-usable components. To use it in a skin, load
+  'mediawiki.legacy.wikibits' (which IEFixes depends on) and that will import
+  IEFixes automatically if user agent conditions are met.
