FPC v1.0 RC2: tag_name: v1.0.0-rc2
body: This is the second release candidate of Fabric Private Chaincode (FPC) v1.0.0

The release focuses on enhanced documentation, samples, testing and bug fixes. More details see `CHANGELOG.md`.
FPC v1.0 RC1: tag_name: v1.0.0-rc1
body: This is the Fabric Private Chaincode (FPC) v1.0.0 release candidate, based on Hyperledger Fabric v2.3.

The release implements the FPC architecture described in the [RFC document](https://github.com/hyperledger/fabric-rfcs/pull/40), submitted for integration in Hyperledger Fabric.

For additional information, check out the [README](https://github.com/hyperledger-labs/fabric-private-chaincode/blob/v1.0-rc1/README.md) and the [docs](https://github.com/hyperledger-labs/fabric-private-chaincode/tree/v1.0-rc1/docs/).
FPC Tech Preview / Concept Release 2.0.0: tag_name: cr2.0.0
body: This release extends the concept release 1.0.1 as follows:

- FPC is now based on _Fabric 2.1_ and integrates more seamlessly, e.g., using external builders.

- It provides a _full-specified and stable functional interface_ which should provide future-proofness for proof-of-concepts build on this release.  For more information, see the [FPC Refence Guides](https://github.com/hyperledger-labs/fabric-private-chaincode/blob/concept-release-2.0/README.md#reference-guides)

- The _overall design and protocols_ are described in details in an RFC ([source](https://github.com/mbrandenburger/fabric-rfcs/blob/fpc-rfc/text/0000-fabric-private-chaincode.md)/[PR with discussion](https://github.com/hyperledger/fabric-rfcs/pull/21)) and [UML diagrams](https://github.com/hyperledger-labs/fabric-private-chaincode/blob/concept-release-2.0/README.md#architecture-and-components).  
  Note that while parts of that design do not exist yet in complete form and will be implemented as part of the MVP milestone, targeted for 20Q3. This makes this implementation _not suitable for a secure production usage_. However, these changes should, as mentioned above, not affect the functional interface as seen by fpc chaincode developers, users of these chaincodes and the operators of the infrastructure!
