This PR looks good in general, but I commented some stuff. Thanks!

[deivid-rodriguez]

I don't think you need to bump the version, since nothing is really changing from a final user perspective. This PR is just making sure that this gem works against newest versions of dependencies.

[jesusalc]

Without the version bump, the gem does not update and it does not resolve the new decency versions.

[deivid-rodriguez]

I don't think you get to be added as the author of this gem just with a single contribution 😅. I'm grateful, and probably the authors of this gem too, for your contribution though.

In fact, I would personally revert all the changes in this file, since you only changing the quoting style, and adding your name and email address.

[jesusalc]

Thanks for reviewing so intensely. Is there anything that is missing or that requires attention for the gem to be ready for 6 ruby 2.7.0 and mongo 7 ?

[deivid-rodriguez]

I have no idea, since it doesn't even seem this repo has TravisCI enabled. We can probably ask the current maintainers to add that?

Have you tried the gem in your application?

[jesusalc]

I am currently using this version, hence the PR request.

[deivid-rodriguez]

This gem should probably declare an official range of supported mongoid versions, and explicitly test those in CI. That sounds like something for a separate PR, though.

[jesusalc]

I tried that but it breaks the older version.

[grzegorz-jakubiak]

could some of the maintainers take care of it? we want to add this functionality to activeadmin-mongoid.

@grzegorz-jakubiak there are no maintainers, have you considered becoming one?

@Ruxton I could become one.
