What the listing says

Judge a sequence of Avro schema versions against a named compatibility mode: BACKWARD, FORWARD or FULL, each with its transitive form, or NONE. A transitive mode compares every version against every earlier one; a per-step mode compares only the immediate predecessor, and the gap that leaves is stated rather than hidden. Every comparison performed is listed with its directional result, so a caller can see what was checked as well as the verdict.
