I only found a few mentions of the new "bottom-up" approach but nothing in detail. An in-depth explanation would be really helpful! Thanks.

So <code>$('#sidebar .menu')</code> is not better (worst in fact) than just <code>$('.menu')</code>. But evidently, $('ul.menu') still the best choice here. Well on other side, we can probably say than selector optimization is no more useful now for common situations. That’s no more exact since jQuery 1.3 and Sizzle, because it now works bottom-top.
