hi what date of august 2021 for new features for all xbox consoles

one more question what date of august 2021 should i check for new features on xbox insider build

what date would early august 2021 be for announcements of new features on older xbox consoles and next gen consoles

I checked the email and I do not see any expiration date at least as far as I can tell. but that's not necessarily the case because I've had other codes long time ago in the past that had didn't have an expiration date and we're no good. but anyways will
I still be able to use it this August once this year goes off? Since the date is August 2021. I should be able to use it this August in 19?
