Yes, yes, I know, there are still 3 whole days to September!.. 
Seriously now, sorry but the dates Fairphone released the individual updates are quite irrelevant, what is important is their content, and that is definitely and totally outdated.
Security patches (because that’s what I am talking about) are perishable goods. Try selling your army suits of chain mail and you’ll understand what I mean.
Already getting those patches 60 days after Google informed the whole world about the underlying vulnerabilities is borderline pointless, by now they are literally yesterday’s news. Still, it’s better than nothing (and it’s not like we customers can do something about it).
(I do notice you avoid the terms “patches” or “security updates”, you just speak about harmless, innocuous “releases”… But the whole point here is security updates, check the thread title. And those need to be as fresh as possible.)
