     1  v1.3.0-rc1 Release Notes - September 24, 2018
     2  ---------------------------------------------
     3  
     4  What's New in Hyperledger Fabric v1.3
     5  -------------------------------------
     6  
     7  The following features/epics are included in this release:
     8  
     9  FAB-10120 - Identity Mixer for anonymous transactions
    10  Keep client identities anonymous and unlinkable through the use of
    11  zero-knowledge proofs.
    12  
    13  FAB-8812 - State-based endorsement
    14  Allows the default chaincode-level endorsement policy to be overridden by a
    15  per-key endorsement policy.
    16  
    17  FAB-2809 - Chaincode pagination of query results
    18  Clients can now page through result sets from chaincode queries, making it
    19  feasible to support large result sets with high performance.
    20  
    21  FAB-8779 - Java chaincode support
    22  As an addition to the current Fabric support for chaincode written in Go and
    23  Node.js, Java is now supported.
    24  
    25  
    26  Changes, Known Issues, and Workarounds
    27  --------------------------------------
    28  
    29  FAB-11122 - Removal of event hub
    30  
    31  The 'old' event hub has been removed in Hyperledger Fabric v1.3.  It is
    32  replaced by the peer channel-based event service which was introduced in
    33  Fabric v1.1.
    34  Applications using the old event hub must switch over to the new
    35  channel-based event service before upgrading to v1.3 peer or SDKs.
    36  
    37  
    38  FAB-12088 - Java chaincode support on s390 architecture
    39  
    40  Java chaincode support is not yet available on s390 architecture.
    41  
    42  
    43  FAB-12134 Same chaincode source receiving fingerprint mismatch error
    44  
    45  Chaincode installed in different ways may result in "chaincode fingerprint
    46  mismatch data mismatch" error upon instantiation.  This may happen when
    47  installing chaincode by using different SDKs. To workaround the problem,
    48  package the chaincode prior to installation and instantiation, by using
    49  the "peer chaincode package" command.
    50  
    51  
    52  Known Vulnerabilities
    53  ---------------------
    54  FAB-8664 - Peer should detect and react when its org has been removed
    55  This is a relatively low severity problem, because it requires a significant
    56  conspiracy of network admins, but it will be addressed in a future release.
    57  
    58  
    59  Resolved Vulnerabilities
    60  ------------------------
    61  None.
