To ease backward compatibility, can you keep HexGrid and deprecate it? For example, have HexGrid subclass HexSingleGrid and issue a DeprecationWarning upon construction?

[Tortar]

This seems like a good idea 👍

[Tortar]

But I have not much time to work on this now, also it should be done with care I think since if we issue it in __init__ we will overwrite the __init__ method in the superclass so this should be managed somehow

[Tortar]

Actually did it

Needs to resolve merge conflict.

I don't see any merge conflict @rht , however I resolved one sometime ago

[rht]

I have rebased the branch. RTD build has a failure that is unrelated to this PR

ImportError: urllib3 v2.0 only supports OpenSSL 1.1.1+, currently the 'ssl' module is compiled with OpenSSL 1.0.2n  7 Dec 2017. See: https://github.com/urllib3/urllib3/issues/2168

@EwoutH any idea about the situation?

[rht]

Merged, thank you!
