asynchronous HTTP request to a MediaWiki entry point. This may require
- increasing the number of server worker threads.
+ increasing the number of server worker threads. $wgRunJobsAsync has been
+ added to disable this feature if needed, falling back to executing the job
+ on the same process but making the execution synchronously.
* $wgDebugLogGroups values may be set to an associative array with a
'destination' key specifying the log destination. The array may also contain
a 'sample' key with a positive integer value N indicating that the log group
* $wgLicenseTerms has been removed as it was unused.
* $wgProfileOnly is now deprecated; set the log file in
$wgDebugLogGroups['profileoutput'] to replace it.
+* $wgMaxBacklinksInvalidate was removed; use $wgJobBackoffThrottling instead

=== New features in 1.23 ===
* ResourceLoader can utilize the Web Storage API to cache modules client-side.
installer has been updated to use it.
* Changes to content typography (fonts, line-height, etc.). See
https://www.mediawiki.org/wiki/Typography_refresh for further information.
+* The Vector skin's visual treatment of external links has been simplified to a
+ single icon (from nine). This should not affect local rules unless they were
+ re-using these icons, which have now been deleted.
* ResourceLoader: mw.loader.using() now implements a Promise interface.
* Add new hook ChangesListInitRows accessed via ChangesList::initChangesListRows.
If called by the ChangesList consumer this gives extensions a chance to batch
process the result set prior to rendering.
* A PoolCounterRedis class was added which can be make use of in $wgPoolCounterConf.
This requires at least one Redis 2.6+ server.
+* $wgProfileToDatabase was removed. Set $wgProfiler to ProfilerSimpleDB
+ in StartProfiler.php instead of using this.
+* (bug 63444) Made it possible to change the indent string (default: 4 spaces)
+ used by FormatJson::encode().
=== Bug fixes in 1.23 ===
* (bug 41759) The "updated since last visit" markers (on history pages, recent
included in all searches.
* Added list=prefixsearch that works like action=opensearch but can be used as
a generator.
+* (bug 24782) Various modules will now use unique continuation parameters.
+* (bug 63249) Cache RecentChanges Atom feed in varnish for 15 seconds.
=== Languages updated in 1.23 ===
* Special:Search no longer has an "include redirects" option on the advanced
tab. Redirects are now included in all searches.

+* The locations of resources have been split between upstream libraries, now in
+ resources/lib/, local libaries in resources/src/, and local forks of upstream
+ libraries, also in resources/src/.
+* BREAKING CHANGE: The automatically-generated function closure with which
+ ResourceLoader wraps all modules' JavaScript code now binds the identifier
+ names 'jQuery' and '$' to the jQuery object of the version of jQuery that is
+ bundled with MediaWiki. If you bind these names to other objects in global
+ scope (like Zepto.js or document.querySelectorAll, for example) you will need
+ to use different names to or re-bind them at the top of each
+ ResourceLoader-loaded module.
+* (bug 52342) Preference "Remember my login" was removed.
