v5.1.9 – Baklava 🍯

Hi again! 👋

This week's release contains some bug fixes, an internal improvement, and an important dependency update. Truffle is now officially Istanbul-compatible and will spin up ganache-core using the Istanbul hardfork by default. Truffle will also postinstall and invoke solc@0.5.16, which also targets Istanbul by default.

As a reminder, if you are using Truffle with ganache-cli or another chain using a different hardfork (petersburg, constantinople, etc.), you'll need to set solc to target that evmVersion:

// ./truffle-config.js

module.exports = {
  /* ... rest of config */

  compilers: {
    solc: {
      version: "0.5.14",
      settings: {
        ...
        evmVersion: "petersburg"
      }
    }
  }
}

Enjoy! ☕

How to upgrade
