Composer v0.18.1

Welcome to Hyperledger Composer v0.18.1.

This is the release to build projects on top of Hyperledger Fabric v1.1-RC1; if you are looking to build on top of the Fabric v1.0, you will need to use the v0.16.x development stream.

Documentation for Hyperledger Composer is under the 'next' branch which can be found here

Documentation for 0.16.x can be found here

Features

✨ #3528 exposes request to transaction processor functions, enabling the calling of HTTP or REST APIs from transaction processor functions. This allows you to move complex computation off the blockchain. For more information, please check out the updated documentation.

Community Contributions

Hyperledger Composer v0.18.0 delivered the ability to use cloud hosted wallets. This enables your wallet store to be held on a different local file location, or within a cloud based service. We would like to give a big shout out to @Rmannn for producing and open sourcing composer-wallet-s3, which is a Hyperledger Composer wallet implementation using Amazon S3 as the store. 👍

Bug Fixes

🐞 #3535 ensures that the Composer version is set within generated package files
🐞 #3538 ensures that the correct wallet is being used during a card import
🐞 #3550 enables the use of cards with certificates in the REST server when in multi-user mode

Notes

⚠️ 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 Fabric1.1-RC1 network. Unfortunately only Composer v0.18.0 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:

  • v0.18.0 and above is 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

Conga Comics

A release simply would not be the same without a CongaComic - fortunately our resident artist @EdMoffatt has completed the snow themed two-parter ⛄️
