Starting a CI 4 project: best auth library?

I'd like to try Myth:Auth but am not sure what versions of Myth:Auth & CI4 would be best together. Looking through this thread I've found the following:

@includebeer: I use Myth:Auth beta 2 with CI 4.0.3 and it's working fine.
@MGatner: I also can tell you I'm using Myth:Auth very happily in production now and it is quite solid
@InsiteFX: I use the development branch and it runs just fine for me

Has anything changed since these posts? Can anyone summarise the best current combination to use?

I'm fairly new to CI & have been creating apps the app-starter Composer way up to now - assume that won't cause any problems. 

Grateful for any advice - thanks.
