The maintainers are pleased to announce that the Hyperledger Fabric v1.1.0-preview release has been published. Download the binaries and images here: http://hyperledger-fabric.read
The v1.1.0-preview release includes Hyperledger Fabric, Hyperledger Fabric CA, and the SDK for Node.js. Note that we are not yet feature complete for the eventual 1.1 release… that will come with the next published release, v1.1.0-alpha. However, we wanted to get the following functionality published to gain some early community feedback on the following features:
FAB-2231 Node.js Chaincode Support
- Building Your First Network and Writing Your First Application tutorials can now be run with either go chaincode or Node.js chaincode.
FAB-5363 Node.js SDK Connection Profile
- Simplify how your applications connect to Fabric with new connection management capabilities and this Tutorial.
FAB-830 Encryption library for chaincode
- Encrypt your data using the new chaincode encryption library, see the Example.
FAB-5346 Attribute-based Access Control
- Enforce access control in your chaincode by using certificate Attribute-based Access Control.
FAB-6089 Chaincode APIs to retrieve client identity
- Obtain transaction submitter identify (certificate, MSP ID, attributes) to make access control decisions using these Chaincode APIs.
FAB-6421 Performance improvements
- Many performance optimizations to significantly improve transaction throughput and response time.
Additionally, there are the usual bug fixes, documentation and test coverage improvements, UX improvements based on user feedback and changes to address a variety of static scan findings.
Many thanks to the 77 developers representing 13 companies and individuals that contributed to this preview release thus far. We continue to see increasing diversity of contribution from member companies. We encourage all developers to join our efforts on Hyperledfer Fabric and other incubated projects. We welcome any feedback you may have, either via this mailing list, JIRA or RocketChat . You can also follow Hyperledger on Twitter or email us with any questions: firstname.lastname@example.org.
