Hyperledger introduces Fabric v1.4 LTS, the first long term support release

Hyperledger, an open source collaborative effort created to advance cross-industry blockchain technologies hosted by The Linux Foundation, today introduced Fabric v1.4 LTS, its first long term support release.

The Fabric developers have been working with network operators and application developers to deliver v1.4 with a focus on production operations and developer ease of use.

Key new production-focused features of Fabric fall into four key areas:

Complete details of the new features can be found in Hyperledger’s What’s New documentation and release notes.

Hyperledger Fabric’s First Long Term Support Release.

Hyperledger Fabric v1.4 LTS marks the first long term support release. Hyperledger noted this as a critically important development for those beginning to deploy Hyperledger Fabric solutions into production and is a reflection of the confidence that the Fabric maintainers have in this latest release.

The policy to date has been to provide bug fix (patch) releases for its most recent major or minor release until the next major or minor release has been published. Hyperledger reports they plan to continue this policy for subsequent releases. However, for Hyperledger Fabric v1.4 LTS, the Fabric maintainers are pledging to provide bug fixes for a period of one year from the date of release (Jan 10). This will likely result in a series of patch releases (v1.4.1, v1.4.2, …), where multiple fixes are bundled into a patch release.

If running with Hyperledger Fabric v1.4 LTS, users can be assured that they will be able to safely upgrade to any of the subsequent patch releases. In the advent that there is a need for some upgrade process to remedy a defect, Hyperledge will provide that process with the patch release.
