Q4 Report
v2.2 is the current LTS release with patch releases quarterly.
project delivered v2.4.0-beta with two significant new features:
Fabric Gateway - The Fabric Gateway 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. Applications will interact with a trusted peer (e.g. at their organization) and the peer will coordinate endorsements from other peers and submission to the ordering service. 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 at their organization 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 delivered along with slim SDKs in the https://github.com/hyperledger/fabric-gateway repository. Check out the client application samples.
Peer unjoin - The new command "peer node unjoin" enables an administrator to remove (unjoin) a channel from a peer.
The peer must be stopped when the command is executed so that channel artifacts can be cleaned up.
The channel's blockchain, state database, and associated entries will be removed from the peer.
When the peer is restarted it will no longer receive blocks for the channel.
