- [x] xref #44315

@simonjayhawkins Failing pipelines are related. Looks like our env files changed on master, so that our pins are not enough. Should we adress this here? The failing envs are picking up aiobotocore-2.0.0, so we can just pin those envs too? > Looks like our env files changed on master

python 3.7 is dropped on master so there has been many changes to the ci on master compared to 1.3.x Pinned the other two envs Thanks @phofl
