Composer v0.20.6

Welcome to Hyperledger Composer v0.20.6, which comes with some bug fixes.
Also we can confirm the Composer v0.20 can be used with hyperledger fabric 1.4.0. It doesn't exploit any features of this release but does tolerate it. As hyperledger fabric 1.4 is the last version of hyperledger fabric v1, this is the last version of fabric the composer will support. Composer will not support the next major release of hyperledger fabric.

Bug fixes

🐞 #4565 Upgrade to latest fabric-shim to address identified fields not allowing non-ascii characters
🐞 #4566 Improve Resource Validator to reject numerical fields which don't contain numbers
🐞 #4480 Ensure logging files are flushed for CLI

Notes

⚠️ If using the Composer tooling to create a Hyperledger Fabric development server, this will now be creating a v1.2.1 server by default. If you are using a different level of Composer v0.16.x, you will need to set the relevant environment variable via export FABRIC_VERSION=hlfvXX when using the Hyperledger Fabric development servers provided by Composer:

  • hlfv1 for Fabric v1.0
  • hlfv11 for Fabric v1.1
  • hlfv12 for Fabric v1.2

The fabric-dev-servers package provided is meant only as a simple hyperledger fabric setup to help you get started with developing with composer using a real fabric. It is not meant to be extended or as a basis for a custom fabric. If you are wondering where versions for hyperledger fabric v1.3 or v1.4 are, these are explicitly not included because you can develop your application using the development fabric 1.2 and still be able to deploy and run it on a fabric 1.3 or 1.4 system.

⚠️ There are multiple support splits across differing Fabric levels, so please be careful with what versions are being used:

  • v0.20.0 and above are compatible with the Fabric 1.2.0, 1.2.1, 1.3.0 and 1.4.x driver only
  • v0.18.2, v0.19.0 and above are compatible with the Fabric 1.1.0 driver only
  • v0.18.0 -> v0.18.1 are compatible with the Fabric RC1 driver only
  • v0.17.3 -> v0.17.6 are compatible with Fabric alpha driver only
  • v0.17.0 -> v0.17.2 are compatible with Fabric preview driver only

⚠️ The is a change in the business network lifecycle administration, and business network card commands between v0.18.2 and v0.19.0
