+v2.2.4 Release Notes - September 8, 2021
+========================================
+
+Improvements
+------------
+
+**peer - New configuration option to disable gossip block forwarding**
+
+If all peers in an organization explicitly set `peer.deliveryclient.blockGossipEnabled` to false,
+no peer in the organization gossips blocks to any other peer in that organization.
+Use this setting when all peers pull blocks from ordering service. 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. For more details see the
+[documentation for enabling the new lifecycle](https://hyperledger-fabric.readthedocs.io/en/release-2.2/enable_cc_lifecycle.html).
