+v2.5.4 Release Notes - August 2, 2023
+=====================================
+
+Fixes
+-----
+
+**Misconfigured certificate can cause a peer or orderer node to fail**
+
+A misconfigured certificate can cause a peer or ordering service node to fail with error:
+`runtime error: index out of range [1] with length 1`.
+Additional handling of certificates in Go 1.19 and above did not handle an error condition correctly.
+The fix will now log an error `failed to traverse certificate verification chain` instead of failing the peer or orderer node.
+[#4320](https://github.com/hyperledger/fabric/pull/4320)
+
+**Orderer startup may fail due to max entry size limit exceeded**
+
+An ordering service node with large blocks may fail to start with error:
+`Failed to create chain support for channel, error: error creating consenter for channel: failed to restore persisted raft data: failed to create or read WAL: failed to read WAL and cannot repair: wal: max entry size limit exceeded`.
+The version of etcd raft included in Fabric v2.5 had a maximum wal (write-ahead log) entry size of 10MB. The issue has been fixed in later versions of etcd raft. Fabric v2.5.4 updates etcd raft to v3.5.9 which includes the fix.
+[#4343](https://github.com/hyperledger/fabric/pull/4343)
+
+
+Dependencies
+------------
+Fabric v2.5.4 has been tested with the following dependencies:
+* Go 1.20.6
+* CouchDB v3.3.2
+
+Fabric docker images on dockerhub utilize Ubuntu 20.04.
+
+
+Deprecations (existing)
+-----------------------
+
+**Ordering service system channel is deprecated**
+
+v2.3 introduced the ability to manage an ordering service without a system channel.
+Managing an ordering service without a system channel has privacy, scalability,
+and operational benefits. The use of a system channel is deprecated and may be removed in a future release.
+For information about removal of the system channel, see the [Create a channel without system channel documentation](https://hyperledger-fabric.readthedocs.io/en/release-2.3/create_channel/create_channel_participation.html).
+
+**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 the 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 channel configuration updates.
+
+**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, and not gossip blocks, 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).
