There has also been a significant amount of Fabric activity in Hyperledger Labs, a few highlights:

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.
