@sindresorhus I think somewhere along the lines this one was incorrectly closed. I just checked on the existing RequireJS app and it looks like it still needs to be updated to match the new template and specs etc. I might try getting this done tomorrow. As far as I can tell, its the only stable app left in

that we need to update (though the YUI one might get a new PR after the weekend).

Take note kids; "Why we don't close issues without a reference or comment"

I've honestly no idea why I closed it...

No worries! These things happen :)

@sindresorhus I've just checked the implementation I checked in but if you'd like to take a look to make sure nothing is missing that would be appreciated. Cheers!
