v1.3.0-rc1 Release Notes - September 24, 2018 --------------------------------------------- What's New in Hyperledger Fabric v1.3 ------------------------------------- The following features/epics are included in this release: FAB-10120 - Identity Mixer for anonymous transactions Keep client identities anonymous and unlinkable through the use of zero-knowledge proofs. FAB-8812 - State-based endorsement Allows the default chaincode-level endorsement policy to be overridden by a per-key endorsement policy. FAB-2809 - Chaincode pagination of query results Clients can now page through result sets from chaincode queries, making it feasible to support large result sets with high performance. FAB-8779 - Java chaincode support As an addition to the current Fabric support for chaincode written in Go and Node.js, Java is now supported. Changes, Known Issues, and Workarounds -------------------------------------- FAB-11122 - Removal of event hub The 'old' event hub has been removed in Hyperledger Fabric v1.3. It is replaced by the peer channel-based event service which was introduced in Fabric v1.1. Applications using the old event hub must switch over to the new channel-based event service before upgrading to v1.3 peer or SDKs. 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 improvements and fixes ---------------------------- Updated to Go version 1.10.4 Updated baseimage version to 0.4.12 For the full list of improvements and fixes, refer to the release change log: https://github.com/hyperledger/fabric/blob/master/CHANGELOG.md#v130-rc1
