KIP-97 — Improved Kafka Client RPC Compatibility Policy

Accepted Kafka 1.0 ProtocolClient

Formalizes a bidirectional client-broker RPC compatibility policy so that new clients can negotiate down to older broker API versions, not just new brokers supporting old clients. The prior one-way policy forced users to upgrade all brokers to a new version before any clients could be upgraded to a matching new version, coupling two independent deployment lifecycles.
