Notes

⚠️ If using the Composer tooling to create a Hyperledger Fabric development server, this will now be creating a v1.1.0 server by default. If you are using Composer v0.16.x, you will need to use Fabric v1.0.x, and you must set an environment variable via export FABRIC_VERSION=hlfv1 when using the Hyperledger Fabric development servers provided by Composer.

⚠️ If you have not specified a version in your npm or docker commands when pulling Composer binaries, and you need to keep using Composer v0.16.x, then you *must specify the version number:

• npm install -g composer-cli@0.16.6
• docker pull hyperledger/composer-cli:0.16.6

We strongly suggest that you migrate to Composer v0.19.x instead, but we understand that existing projects may need to stick with Composer v0.16.x for the time being.

⚠️ Business Network Cards are not transferable between v0.16.x and v0.17.x onwards. It will be necessary to manually clear your card store in order to use a different version. Please note that the CLI command to delete a named card will not work correctly if targeting a named card that was created from a different version.

⚠️ The Composer Tools is now setting up a Fabric v1.1 network. Unfortunately only Composer v0.18.2 and above are (and will be) compatible with this alpha driver. There are multiple support splits across differing Fabric levels, so please be careful with what versions are being used:

• 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

Dearly beloved, we are gathered here today to bare witness to another #CongaComic creation from our resident artist @EdMoffatt, who has probably been forced to set an email rule to ignore GitHub emails due to all the tags he gets in these release notes. @EdMoffatt @EdMoffatt @EdMoffatt
