> you can push an update to your website and your mobile app gets new features for free
...has Apple changed its stance on adding features without going through review? I thought that's prohibited (because at least for games that's a big no-no).
Of course, but it's about features that slip in through the web page (for instance via Javascript).
Technically, you're not allowed to ship games which then download interpreted Lua scripts which change or add features to the game for instance. You'll have to release an update through the App Store instead.
(unless Apple has relaxed this rule of course, I haven't checked for the last 4 years or so)
