Release Note Draft Snippet

[clemsos]

It seems that Hardhat test runner is not catching the error messages properly - while solidity-coverage does. Instead we got a

AssertionError: Expected to fail with NOT_ENOUGH_FUNDS, but failed with: 
Error: VM Exception while processing transaction: reverted with an unrecognized custom error

Hardhat should support custom errors, so maybe sth in passing around the errors defs

Here is a repro repo to see where the problem is https://github.com/clemsos/custom-errors-repro

Let's use a more explicit error name but then LG!
