The warning for not enabling callSuper cannot be avoided, but there are legal reasons for using it, so, changed it: explicitly setting 'callSuper=false' removes the warning. You only get the warning

if callSuper is false because that's the default.

 ----------------
 
+### v0.8.3
+
+* @EqualsAndHashCode (and, indirectly, @Data) generate a warning when overriding a class other than java.lang.Object but not setting EqualsAndHashCode's callSuper to true. There are, however, legitimate reasons to do this, so this warning is now no longer generated if you explicitly set callSuper to false. The warning text now also refers to this action if not calling super is intentional.
+
 ### v0.8.2
 
 * @EqualsAndHashCode and @ToString created; these are subsets of what @Data does (namely: generate toString(), and generate equals() and hashCode() implementations). @Data will still generate these methods, but you can now generate them separately if you wish. As part of this split off, you can now specify for toString generation to include the field names in the produced toString method, and for all 3 methods: You can choose to involve the implementation of the superclass, and you can choose to exclude certain fields.
