There has also been a significant amount of Fabric activity in Hyperledger Labs.

Current Plans

The largest item being worked in 2021 is the Fabric Gateway, a new component that will implement much of the high-level 'gateway' programming model. This will remove much of the transaction submission and query logic from the client application and shift it to a common gateway running within the Fabric peer, enabling each of the various client SDKs to be slimmer, more consistent, and require less maintenance. It will also simplify the administrative overhead of running a Fabric network because client applications will be able to connect and submit transactions via a single network port rather than the current situation where ports have to be opened from a client application to multiple peers across potentially multiple organizations. The Fabric Gateway is expected to be function complete for a Q3 v2.4.0-beta release.

Other work items in plan or in progress:

• A feature to purge private data stores, which will help solutions meet GDPR requirements. An RFC is expected so that we can gather additional feedback from the community.
• A feature to unjoin a peer from a channel.
• A more realistic Node.js SDK sample application demonstrating good practices (connection management, error handling, timeouts, retries, etc)
• Guidance for kubernetes deployments
• Open sourcing of the IBM Blockchain Platform console as a Hyperledger Lab

Additional discussion of Fabric roadmap can be found in this contributor meeting recording.
