production.
=== Configuration changes in 1.23 ===
+* $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
+ should be sampled by dispatching one in every N messages on average. The
+ sampling is random.
+* In addition to the current exception log format, MediaWiki now serializes
+ exception metadata to JSON and logs it to the 'exception-json' log group.
+ This makes MediaWiki easier to integrate with log aggregation and analysis
+ tools.
=== New features in 1.23 ===
+* ResourceLoader can utilize the Web Storage API to cache modules client-side.
+ Compared to the browser cache, caching in Web Storage allows ResourceLoader
+ to be more granular about evicting stale modules from the cache while
+ retaining the ability to retrieve multiple modules in a single HTTP request.
+ This capability can be enabled by setting $wgResourceLoaderStorageEnabled to
+ true. This feature is currently considered experimental and should only be
+ enabled with care.
+* (bug 6092) Add expensive parser functions {{REVISIONID:}}, {{REVISIONUSER:}}
+ and {{REVISIONTIMESTAMP:}} (with friends).
+* Add "wgRelevantUserName" to mw.config containing the current
+ Skin::getRelevantUser value
=== Bug fixes in 1.23 ===
+* (bug 41759) The "updated since last visit" markers (on history pages, recent
+ changes and watchlist) and the talk page message indicator are now correctly
+ updated when the user is viewing old revisions of pages, instead of always
+ acting as if the latest revision was being viewed.
+* (bug 56443) Special:ConfirmEmail no longer shows a "Mail a confirmation code"
+ when the email address is already confirmed. Also, consistently use
+ "confirmed", rather than "authenticated", when messaging whether or not the
+ user has confirmed an email address.
=== API changes in 1.23 ===
+* (bug 54884) action=parse&prop=categories now indicates hidden and missing
+ categories.
=== Languages updated in 1.23===
changes to languages because of Bugzilla reports.
=== Other changes in 1.23 ===
+* The global variable $wgArticle has been removed after a lengthy deprecation
