 ### Notable fix: Namespace inheritance
 
-Namespace behavior when reparenting nodes has historically been poorly specified and the behavior
-diverged between CRuby and JRuby. As a result, making this behavior consistent in v1.12.0 introduced
-a breaking change.

 #### Compensating Feature in XML::Document
 
-This release of Nokogiri introduces a new `Document` boolean attribute, `namespace_inheritance`,
-which controls whether children should inherit a namespace when they are reparented.
-`Nokogiri::XML:Document` defaults this attribute to `false` meaning "do not inherit," thereby making
-explicit the behavior change introduced in v1.12.0.

 #### Fix for XML::Builder
 
-However, recognizing that we want `Builder`-created children to inherit namespaces, Builder now will
-set `namespace_inheritance=true` on the underlying document for both JRuby and CRuby. This means that, on CRuby, the pre-v1.12.0 behavior is restored.
