Sure, there are hundreds of thousands more that apply to even older releases (or may not mention any release), but if you ...
can never find a relevant answer here
... then you are hitting some really bad odds ;-). But, as @ArturMeinild mentioned, if that's the case, then please do add your question! If there's already a question out there that doesn't have an answer (or that answer doesn't work for you) - Upvote and perhaps even add a bounty!
