Where is iTunes Match in iTunes 12?

I simply can't find it. I read that to update Match, I should go to Store > Update iTunes Match, but there's nothing called Store - not in the menu, and not in the strip of options on top of iTunes. There's something called 'iTunes Store', but when I go there, theres just music I can buy, no Match-options (there's a link to iTunes Match, but that only lets me add my computer – I don't need to add it as I already have Match).

So where is it gone? How do I update Match? Getting really frustrated here...
