Latest asset store version or stick with beta?

I’m on beta 4.2.18 and was thinking to update to the latest asset store version to make sure my codebase is in sync.

Or is the beta still moving ahead of the asset store version? If so what state is that in, or what ETA might the next release out of beta happen?

Any other considerations when thinking about making an update right now from an old beta version?

The latest asset store version has surpassed the beta now. So you can use it.

4.2.18 wasn’t even a beta version. That was a normal release.
