"4.0.0 beta" vs. "4.0.0 of 2021-6-29"

Hello.
I have “4.0.0 beta” installed. Please, give an advise:

1)Is “4.0.0 beta” different from “4.0.0 of 2021-6-29”?
2)Shall I remove “4.0.0 beta” to install “4.0.0 of 2021-6-29”?

Yes, they are different. Yes you should remove the beta first, then install the official version for the Chrome webstore.
