Hyperledger Fabric continues to mature, as evidenced by the following observations throughout this report:
The commit rate and mailing list activity were down compared to the same period last year. PRs and mailing list questions are generally turned around quickly.

v2.2 is the current LTS releases with patch releases quarterly. v1.4 LTS went end of support in April 2021. Production users are encouraged to use v2.2, users who want to try new features are encouraged to use v2.3 and v2.4.0-alpha and provide feedback.

Upcoming releases planned this quarter:
v2.3 added two major features which are seeing encouraging adoption in the community:
The project was busy maintaining the releases and preparing for a v2.4.0-beta release with the new Fabric Gateway (details below).
Additionally the project has been planning future work through the RFC process.

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