I'm on Memu 6.0.1 (I think this is the correct version, not sure how to check) w/ no Google Apps and the 3.4.0 patch is working for me.
However, I think it's safe to say Bluestacks' compatibility was killed. I've only installed the APK (tried two different variants from two different sites) and I keep getting booted before I can download the files. Everything that should be disabled on Bluestacks is, nothing has randomly turned back on.
