Absolutely! All the fixes we’re putting in are available to everyone the moment they go in through GitHub. Entitlement checking went in yesterday, and we’re working on a few compat / signing issues at the moment.
Also, and update from Korea about MSAA, looks like it will hit this week, but will be supported on certain devices for 4.9. Looks like all GearVR compatible android devices are on that list, fortunately.
