Amazon Managed Blockchain now supports Hyperledger Fabric v1.4
Amazon Managed Blockchain now supports Hyperledger Fabric version 1.4 for new networks. In addition to stability improvements and bug fixes, this version improves Node.js and Java client SDKs for easier chaincode development and deployment, enhances private data collections to make the feature more stable and easier to use, supports Java chaincode, and has additional metrics to monitor network activity. Customers can also now select CouchDB as their state database, enabling them to perform richer state data queries from chaincode using JSON storage and query formats.
