Project Health
Hyperledger Fabric continues to mature, as evidenced by the following observations 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 least quarterly.
The project was busy maintaining the two LTS releases, given an increasing 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 available, they are likely slightly down as well.
The project is working towards a v2.3 release in November. Major features include ledger checkpoint and channel participation management without a system channel.
Ledger checkpoint will allow new peers to join a channel from a checkpointed snapshot of the state database. This reduces the time to join a channel, and reduces the storage size required to maintain a ledger. In the future it will also be possible to prune/archive old blocks to bring the same benefit to existing peers.
The channel participation management feature improves the privacy and scalability of the ordering service since a global 'system channel' will no longer be needed for the creation and management of channels.
The project is shifting from a release cadence of every 3 months to every 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 quarterly release cadence.
The other active development items mentioned above for Q2 continue into Q3 as well.
No maintainer changes for core fabric project this quarter. 12 of 13 from IBM.

Documentation translation was a driver in the increased contributor diversity.
