WPGraphQL 2.1.0 warning

[lightson]

When attempting to update the main WPGraphQL plugin I receive this warning:

I see that WPGraphQL v2.0 introduces breaking changes; and I've held off updating it for a little while awaiting possible update for the related ACF plugin, but that's not arrived.

Should I be concerned with this; or is WPGraphQL for ACF 2.4.1 compatible with WPGraphQL 2.x?

(I use these plugins on a hobby site to great effect, but sadly I don't have staging).
