Project Health<= /span>
Hyperledger Fabric continues to mature, as evidenced by the following ob= servations throughout this report:
The commit rate and mailing list activity are down slightly compared to = the same period last year.
The project would benefit from increased maintainer diversity.
None.
v1.4 and v2.2 are the current LTS releases. Each has patch releases at l= east quarterly.
The project was busy maintaining the two LTS releases, given an increasi= ng number of production deployments.
In active development:
Mailing list activity:
557 messages in Q3 2019 versus 480 messages in = Q3 2020, down 14%. While Chat and Stackoverflow numbers are not av= ailable, they are likely slightly down as well.
The project is working towards a v2.3 release in November. Major feature= s include ledger checkpoint and channel participation management without a = system channel.
Ledger checkpoint will allow new peers to join a channel from a checkpoi= nted snapshot of the state database. This reduces the time to join a channe= l, and reduces the storage size required to maintain a ledger. In the futur= e it will also be possible to prune/archive old blocks to bring the same be= nefit to existing peers.
The channel participation management feature improves the privacy and sc= alability of the ordering service since a global 'system channel' will no l= onger be needed for the creation and management of channels.
The project is shifting from a release cadence of every 3 months to ever= y 4 months. The change is driven by the overall project maturity/stability/= velocity, as well as the difficulty for consumers to keep up with a quarter= ly release cadence.
The other active development items mentioned above for Q2 continue into = Q3 as well.
No maintainer changes for core fabric project this q= uarter. 12 of 13 from IBM.

Documentation translation was a driver in the increased contributor dive= rsity.
