Right, but why agonize over users who are intent on shooting themselves in the foot? As long as they have the notice, we could say “well, we did warn you”… I support de-modal-izing this:
We could add some words to encourage users to update, e.g.
We’ve updated this site. Please update, or things might get weird
Not that exact language, but you see what I mean 
I would like us to improve this for the current release, how much work is this in your estimation @sam… I think the old school way
leaves a lot to be desired and I much prefer @awesomerobot mockup. Not proposing a huge change to behavior, just get rid of the jarring big ol’ giant OK/CANCEL dialog?
Probably not too much work to add this in, @martin can take it next week.
This change has been merged:

Now the popup shows at the top of the page and is much less in-your-face than a modal
