-     *  10: to-be-determined changes
+     *  10: local variable type inference (var)

+     * Additions in this release include local variable type inference

In both hunks use "local-variable type" (as in the name of its JEP, 286)
so as to distinguish it from "local variable-type".

Otherwise, looks good.
