@ -111,6 +111,14 @@ activate it using ``pragma experimental ABIEncoderV2;`` - we kept
the same pragma, even though it is not considered experimental
anymore.
The set of types supported by the new encoder is a strict superset of
the ones supported by the old one. Contracts that use it can interact with ones
that do not without limitations. The reverse is possible only as long as the
non-``ABIEncoderV2`` contract does not try to make calls that would require
decoding types only supported by the new encoder. The compiler can detect this
and will issue an error. Simply enabling ``ABIEncoderV2`` for your contract is
enough to make the error go away.
