There is a documented and tested migration path from +Kafka to Raft, and existing users should migrate to the newer Raft consensus type. +For compatibility with existing deployments, Kafka is still supported, +but may be removed entirely in a future release. +Additionally, the fabric-kafka and fabric-zookeeper docker images are no longer updated, maintained, or published. + +**Fabric CouchDB image is deprecated** + +v2.2.0 added support for CouchDB 3.1.0 as the recommended and tested version of CouchDB. +If prior versions are utilized, a Warning will appear in peer log. +Note that CouchDB 3.1.0 requires that an admin username and password be set, +while this was optional in CouchDB v2.x. See the +[Fabric CouchDB documentation](https://hyperledger-fabric.readthedocs.io/en/v2.2.0/couchdb_as_state_database.html#couchdb-configuration) +for configuration details. +Also note that CouchDB 3.1.0 default max_document_size is reduced to 8MB. Set a higher value if needed in your environment. +Finally, the fabric-couchdb docker image will not be updated to v3.1.0 and will no longer be updated, maintained, or published. +Users can utilize the official CouchDB docker image maintained by the Apache CouchDB project instead. + +**FAB-7559: Support for specifying orderer endpoints at the global level in channel configuration is deprecated.** + +Utilize the new 'OrdererEndpoints' stanza within the channel configuration of an organization instead. +Configuring orderer endpoints at the organization level accommodates +scenarios where orderers are run by different organizations. Using +this configuration ensures that only the TLS CA certificates of that organization +are used for orderer communications, in contrast to the global channel level endpoints which +would cause an aggregation of all orderer TLS CA certificates across +all orderer organizations to be used for orderer communications. + +**FAB-17428: Support for configtxgen flag `--outputAnchorPeersUpdate` is deprecated.** + +The `--outputAnchorPeersUpdate` mechanism for updating anchor peers has always had +limitations (for instance, it only works the first time anchor peers are updated). +Instead, anchor peer updates should be performed through the normal config update flow. + +**FAB-15406: The fabric-tools docker image is deprecated** + +The fabric-tools docker image will not be published in future Fabric releases. +Instead of using the fabric-tools docker image, users should utilize the +published Fabric binaries. The Fabric binaries can be used to make client calls +to Fabric runtime components, regardless of where the Fabric components are running. + +**FAB-15317: Block dissemination via gossip is deprecated** + +Block dissemination via gossip is deprecated and may be removed in a future release. +Fabric peers can be configured to receive blocks directly from an ordering service +node by using the following configuration: +``` +peer.gossip.orgLeader: true +peer.gossip.useLeaderElection: false +peer.gossip.state.enabled: false +``` + +**FAB-15061: Legacy chaincode lifecycle is deprecated** + +The legacy chaincode lifecycle from v1.x is deprecated and will be removed +in a future release. To prepare for the eventual removal, utilize the v2.x +chaincode lifecycle instead, by enabling V2_0 application capability on all +channels, and redeploying all chaincodes using the v2.x lifecycle. The new +chaincode lifecycle provides a more flexible and robust governance model +for chaincodes. For more details see the +[documentation for enabling the new lifecycle](https://hyperledger-fabric.readthedocs.io/en/release-2.2/enable_cc_lifecycle.html).
