@ArthurJWH please rebase your branch to develop so we can properly review this PR. I'm under the impression the 26 commits of this PR should not belong to this git history

@ArthurJWH tests and linters are not passing.... CHANGELOG needs to be updated,

and, finally, I think there's smth wrong with your git tree again... Could you check the git diff and verify everything is good with your PR?

Let us know whenever you have the PR ready to be reviewed again please.
