Composer v0.19.15

Welcome to Hyperledger Composer v0.19.15, which comes with some performance and functional fixes, to help keep you all Composing.

Features

✨ #4314 gives the REST server some ❤️ enabling dynamic logging and the ability to turn off the test interface. And it's not even Christmas.

Bug fixes

🐞 #4372 removes signature verification from within the Composer client, this occurs downstream anyway and was acting as a bottleneck during transactions ... now it is gone 🐎
🐞 #4391 reduces the number of connected peer objects, meaning that the same will be used for query and submit
🐞 #4384 modifies the logging trace so that only identifiers are logged, meaning that less time is spent writing trace an more time running the code
🐞 #4394 updates dependancies to remove the warnings when performing an npm install

Notes

⚠️ If using the Composer tooling to create a Hyperledger Fabric development server, this will now be creating a v1.2.0 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

⚠️ 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 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
