v1.4.1-rc1 Release Notes - March 29, 2019 ----------------------------------------- What's New in Hyperledger Fabric v1.4.1 --------------------------------------- The following features are included in this release: FAB-6135 - Raft Consensus The ordering service now provides an option to use the Raft Consensus algorithm. See https://raft.github.io/ for details on the Raft algorithm. Additional operational metrics and health checks FAB-13088 Endorser metrics FAB-14077 Orderer communication metrics FAB-11937 Raft metrics FAB-13237 Metrics for log records FAB-13341 Kafka health check FAB-12908 CouchDB health check Changes, Known Issues, and Workarounds -------------------------------------- FAB-14723 - Deprecate CAR package format Support for packaging chaincode using the CAR format will be removed in v2.0.0. FAB-12088 - Java chaincode support on s390 architecture Java chaincode support is not yet available on s390 architecture. FAB-12134 - Same chaincode source receiving fingerprint mismatch error Chaincode installed in different ways may result in "chaincode fingerprint mismatch data mismatch" error upon instantiation. This may happen when installing chaincode by using different SDKs. To workaround the problem, package the chaincode prior to installation and instantiation, by using the "peer chaincode package" command. Known Vulnerabilities --------------------- FAB-8664 - Peer should detect and react when its org has been removed This is a relatively low severity problem, because it requires a significant conspiracy of network admins, but it will be addressed in a future release. Resolved Vulnerabilities ------------------------ None. Other noteworthy improvements and fixes --------------------------------------- FAB-14420 - Allow statically configured CAs for TLS communication with orderers FAB-13471 - Fix for multiple chaincode upgrades in a single block FAB-14687 - Fix memory leak in gossip message store Updated to Go version 1.11.5 Updated baseimage version to 0.4.15 For the full list of improvements and fixes, refer to the release change log: https://github.com/hyperledger/fabric/blob/release-1.4/CHANGELOG.md#v141-rc1
