v5.1.21 – `immutable` caramel

Good day!

Please enjoy this Truffle release! Today, we bring you two notable enhancements:

1. Firstly, @rkalis has updated Truffle's migration output to include both decimal and hexadecimal for gas values! Pretty handy! 📋
   
2. Secondly, Solidity v0.6.5 and above now provide the immutable keyword! 💪Thanks to @haltman-at's quick action and due preparedness, Truffle's debugger and decoder now both support this new language feature!

As always, check the changelog below for more, and please do take care! Let us know if you run into any issues. 🙇

How to upgrade

We recommend upgrading to the latest version of Truffle by running:

npm uninstall -g truffle
npm install -g truffle
