- Avoid thrown errors if the target doesn't have propertyIsEnumerable. #252
 
 - isMergeableObjectis now only called if there are two values that could be merged. a34dd4d2
 
 - Fix: falsey values can now be merged. #170
 
 - Properties are now only overwritten if they exist on the target object and are enumerable. #164
Technically this could probably be a patch release since "which properties get overwritten" wasn't documented and accidentally overwriting a built-in function or some function up the property chain would almost certainly be undesirable, but it feels like a gray area, so here we are with a feature version bump.
