The Hyperledger Fabric maintainers are pleased to announce the availability of Fabric v1.4.2!

v1.4.2 delivers the next set of patches and fixes on the Fabric 1.4 long-term support (LTS) release.

v1.4.2 also delivers Kafka to Raft migration capability for the ordering service. The Raft-based ordering service is simpler to operate since it requires no dependencies external to the orderer nodes. It also enables the ordering service to be provided by different organizations across different data centers. For these reasons we expect Raft to become the preferred ordering service choice for production Fabric networks.

Please see the release notes for additional improvements and suggestions:
