version 3 released

[RostyslavDzhohola]

I have an issue with installing "npm i ethereum-waffle".
It cannot find bunch of files in the node-modules
Example:
2020-10-15T18_00_02_936Z-debug.log
npm WARN tar ENOENT: no such file or directory, open 'C:\Users\Rostyslav\AppData\Roaming\VS-Projects\buidler-tutorial\node_modules\.staging\ethashjs-8a961820\.prettierrc'

I have followed instructions from https://buidler.dev/tutorial/writing-and-compiling-contracts.html
Please advice.
