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, 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+ and v0.19.x 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
