=== Compatibility issues (excluding feature bug fixes)
-* Array#sum is implemented. Ruby itself has no compatibility problem
- because Ruby didn't have sum method for arrays before Ruby 2.4.
+* Array#sum is implemented. [Feature #12217]
+ Ruby itself has no compatibility problem because Ruby didn't have sum method
+ for arrays before Ruby 2.4.
However many third party gems, activesupport, facets, simple_stats, etc,
defines sum method. These implementations are mostly compatible but
there are subtle differences.
