 | What’s new in the v2.0 Alpha Read Full ReleaseA word about the Alpha releaseThe Alpha release of Hyperledger Fabric v2.0 allows users to try out two exciting new features — the new Fabric chaincode lifecycle and FabToken. The Alpha release is being offered to provide users a preview of new capabilities and is not meant to be used in production. Additionally there is no upgrade support to the v2.0 Alpha release, and no intended upgrade support from the the Alpha release to future versions of v2.x. |

v1.4.1 delivers the first set of patches on the Fabric 1.4 long-term support (LTS) release. v1.4.1 also delivers the next phase of the v1.4 release theme around improved production operations. New operational metrics and health checks are included in v1.4.1, as well as a Raft-based ordering service.
The Raft-based ordering service provides crash fault tolerance like the Kafka ordering service implementation, without the need to manage external dependencies, making it easier to deploy and operate. Additionally, when using Raft, ordering service nodes can be provided by different organizations across the world in different data centers. For these reasons, we expect Raft to become the preferred ordering service choice for new production Fabric networks. Fabric developers and testers have been using the battle-tested etcd implementation of Raft for a long time, and the maintainers are pleased to add Raft support to the Fabric 1.4 LTS release. We also expect to deliver Kafka to Raft migration capabilities in coming releases.
