+* (T7645) The "Signature" button on the edit toolbar is now hidden by default
+ in non-talk namespaces. A new configuration variable,
+ $wgExtraSignatureNamespaces, controls in which subject (non-talk) namespaces
+ the "Signature" button on the edit toolbar will be displayed.
+* $wgResourceLoaderUseESI was deprecated and removed. This was an experimental
+ feature that was never enabled by default.
