hey @rushelex can you sync this branch with main and that maybe fixes CI issues

Wouldn't this change introduce a breaking change? I mean, all users of apollo-react would have to install deepmerge as their runtime dependency, otherwise something might break, right?

@HermanBilous no, users of apollo-react will not have to install an additional dependency because this dependency is already installed in this package in dependencies
