I'm building a newer version to see how it goes, we can't use a beta 
version or tip version, any thoughts on a good stable version to build? I'm 
in the middle of a 88.0.4324.182 build but I'm not sure that is any better. 
I've had a hard time determining what should be a good version to build 
arm64.

Thanks for the response!
