And anyone running the stable builds have therefore never been updated to an at all recent build… sighs

And looking at my phone, I have no idea how I'm meant to update to the milestone builds. The updater lets me select "stable" or "all (inc. nightly)", and nowhere do the milestone builds appear…

None of this is helping me believe there's really any decent security story. Abandon all users who don't check the website (or whatever) to find out about releases, trusting the built-in updater to provide updates. Never publish any security advisories that cover your distribution…
