v5.0.27 — Peaches & Cream 🍑

Hey all! 👋

This week brings a special treat! ✨

This release marks Truffle's formal integration with Hyperledger Fabric's chaincode EVM.
It also brings a fix to re-enable proper decoding of Quorum private values.

Example config for using Truffle with Hyperledger Fabric's EVM chaincode

module.exports = {
  networks: {
    fabricNetwork: {
      host: "127.0.0.1",
      port: 5000, // default Fab3 port
      network_id: "*",
      type: "fabric-evm"
    }
  }
}

Also, for those using native solc and/or docker solc for compilations, faster parsing using solc-js is now available!

Example config

module.exports = {
  compilers: {
    solc: {
      version: "native",
      parser: "solcjs"
    }
  }  
}

And, for those who enjoy Ganache's forking feature, truffle develop now supports fork as a config option.

Example config

module.exports = {
  networks: {
    develop: {
      fork: "https://cloudflare-eth.com/",
      network_id: 1
    }
  }  
}

Special thanks to...

• @itinance for updating truffle-hdwallet-provider's documentation
• @chebykin for adding support for forked Truffle mnemonic's!
