For more +information see deprecation announcement below: **FAB-15317: Block dissemination via gossip is deprecated**. + +**orderer - [FAB-18484] Return transaction forwarding result back to the client synchronously** + +With this improvement a Raft follower waits for the transaction to be forwarded to the Raft leader, +and returns the result (success or failure) back to the client accordingly. +Prior to this improvement, the Raft follower returned success after enqueueing it into the message queue, +which might have resulted in the transaction being dropped but a success being returned to the client. +Application clients should still monitor transaction commit events, since the Raft leader is not guaranteed +to deliver the transaction into a block in exception scenarios, but this improvement avoids +transactions from being dropped when there are connection issues between a Raft follower and Raft leader. + +**peer and orderer - Make gRPC maximum message size configurable** + +This improvement makes gRPC maximum message size configurable in peer and orderer. +Previously the maximum message size was hardcoded to 100 megabytes. +Since all nodes should be consistent it is recommended to keep +the default value of 100 megabytes for MaxRecvMsgSize & MaxSendMsgSize. +The value can be configured if needed however. +Configure in peer core.yaml with `peer.maxRecvMsgSize` and `peer.maxSendMsgSize`. +Configure in orderer orderer.yaml with `General.MaxRecvMsgSize` and `General.MaxSendMsgSize`. + + +Dependencies +------------ +Fabric v2.2.4 has been tested with the following dependencies: +* Go 1.16.7 +* CouchDB v3.1.1 + + +Deprecations (existing) +----------------------- + +**FAB-15754: The 'Solo' consensus type is deprecated.** + +The 'Solo' consensus type has always been marked non-production and should be in +use only in test environments, however for compatibility it is still available, +but may be removed entirely in a future release. + +**FAB-16408: The 'Kafka' consensus type is deprecated.** + +The 'Raft' consensus type was introduced in v1.4.1 and has become the preferred +production consensus type. 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 +Additionally, the fabric-kafka and fabric-zookeeper docker images are no longer updated, maintained, or published.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 +peer.deliveryclient.blockGossipEnabled: 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.
