From The Tour, specifically the "Don't ask about" section
Weren't the "Creating or developing a web application" and "Web browsers, including features and browser extensions/add-ons" items moved to the top of the list? If not, they should be. (That's a majority of our off-topic questions.)
Also, the "recommendations" prohibition has changed to be recommendations requests in general. This should be re-worded to match up with the Help Center. (And is should be "recommendation requests" that are off-topic. "Recommendations" are what those naughty questions are trying to engender.)
