v0.20.0
Composer v0.20.0
Welcome to Hyperledger Composer v0.20.0, which is so shiny that it runs on top of Fabric 1.2, like a star on top of a majestic Christmas tree hung with sparkly (yet tasteful) decorations.
🔥 Please note that Fabric 1.2 is required and you should stick with Composer 0.19.x if you are using Fabric 1.1.
Features
✨ Toleration of Fabric 1.2. This means that it works with Fabric 1.2 but the Composer code does not attempt to exploit any new capabilities found in Fabric 1.2.
Bug fixes
None.
Doc Updates
📖 #4311 Grammar fixes to the docs from @manifestlifeinc
📖 #4318 Updates to the multi-org tutorial for Fabric 1.2, and improvements to transaction processor documentation of return values for the REST server from @mahoney1
Please do read the documentation, and if you really want more information, then check out our integration tests as the examples are being run as part of our regression test suite 👌
Notes
export FABRIC_VERSION=hlfv11 when using the Hyperledger Fabric development servers provided by Composer. 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.
npm or docker commands when pulling Composer binaries, and you need to keep using and earlier Composer version, then you must specify the version number:
npm install -g [email protected]docker pull hyperledger/composer-cli:0.19
Documentation for v0.20.x can be found here
Documentation for v0.19.x can be found here

v0.19.12
Composer v0.19.12
Welcome to Hyperledger Composer v0.19.12, which comes with features and fixes to help give you the best Composer experience yet 👍 There are two significant features inbound within this release, so pay special attention to the release notes, and maybe visit the associated documentation, before treating yourself to the Conga Comic at the end 🍾 ⚽️
Features
✨ Ever wanted to get a return value from running a Transaction? Well ... now you can 😱 PRs #4207, #4218, #4219, #4220, #4223, #4224, #4226, #4227 and #4228 come from his Royal Conganess himself, @sstone1. They enable the option to return data to client applications from transaction processor functions. This can be useful for returning a receipt to the submitter of the transaction, or returning an asset modified by the transaction to avoid a separate lookup of the asset after the transaction has been committed.
✨ The same set of PRs deliver the ability to have a "read-only" transaction, whereby the transaction is not committed - it will not be endorsed by multiple peers on the blockchain network, it will not be sent to the ordering service, nor will it publish any events. This feature can be useful when the APIs that client applications can use to read data from the business network are too limited for your use case. For example, a client application may wish to get all of the assets across multiple business networks deployed to multiple channels in a single call to the blockchain network...this (and more) is now possible 👍
Bug fixes
🐞 #4179 is a fix in the angular generator to prevent a forced page refresh after adding assets
🐞 #4204, #4206 , #4209 and #4212 are fixes within the to/fromJSON() process to help with performance
🐞 #4162 exports the classes in the composer-cli package so that they can be consumed, with thanks to @simonghrt for the contribution 👍
🐞 #4200 makes node-plant-uml package in composer-common a dev-dependancy to help put it on a diet, care of @mttrbrts
🐞 #4222 is an edit to the API documentation to correct the naming within the example code, and comes with a shout out to @bjrnt 🎉
Doc Updates
📖 #4230 is the associated documentation for the features delivered within this release. We strongly urge you to check them out. There are two key documentation items here:
