Project Health

Hyperledger Fabric is fairly mature and stable with a Long-term support (LTS) release and incremental new features being added in minor releases. There is less churn and fewer commits than in years past, with continued focus on quality and support. New features get proposed, approved, and implemented based on a community RFC process. Mailing list activity is down a bit compared to prior years. PRs and mailing list questions are generally turned around quickly.

Current Plans

The project is working on a v2.5.0 release in the release-2.5 branch, with a feature to Purge the history of private data. The feature may help organizations meet GDPR requirements with the ability to delete private data while preserving a hash of the data on the blockchain. The v2.5 release is expected around end of 2022 and is expected to become the next long-term support release. 

Fabric v3.0 release development has started, primarily around refactoring the ordering service for the upcoming BFT consensus integration. In the v3.0 release we are considering deprecation and removal of some features that have historically made deployment difficult, such as docker-in-docker chaincode building.

The project is investigating creation of ARM based binaries and docker images, due to the M1 mac (ARM-based) gaining traction in the developer community.

The project has started to shift CI from Azure Pipelines to Github Actions across the various Fabric repositories.

More details can be found in the project ZenHub board, this board provides a current priority view of the Github issues across the various Fabric repositories.
