Composer v0.19.6

Welcome to Hyperledger Composer v0.19.6. This release comes with a bug-fixing-bonanza ... the most noticeable of which being the enablement of the 'back' button in the browser when using Playground. 🥂

Check out the rest of the release notes below and treat yourself to a fresh new Conga Comic at the end 👍

Features

✨ #3984 provides some enhancements to the embedded connector to be more consistent with a real fabric in how identities are managed

Bug fixes

🐞 #3906 is a beauty. Ever wanted to use the 'back' button in Playground? Well, you might have noticed that it didn't work.... until now 🌟 👍 Yes, that's right ... the browser 'back' button has been enabled. 🐞 #3992 enforces stricter checking in JSON population of resources ... so you can no longer make up your own fields. They would have been ignored during the population, but now you are explicitly told that they will not be created. 🐞 #3983 updates the documentation for the uninstall process for the dev-servers 📖 🐞 #4008 gives even more love to the Playground, removing the final traces of org.acme. They never provided us with any anvils, so we have stopped advertising them. 🐞 #4012 lets us give a shout out to @zachgoll for providing a fix to the linting error resulting from the angular generator 🐞 #4027 and #4049 reduce the number of getState() calls to couchDB when dealing with registries during context build.

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
