That's not actually any better, it's worse. A guide that's not updated for 5-10 years means that it's missing 5-10 years of material and newer references. Plus, as a guide it still fails, numerous sections are missing any references to follow, that is: It is a guide that often points you nowhere.
As I pointed out before: It took over 20 years for them to add a section on security. That was a critical issue when it first came out, an even bigger issue in the 2010s when v3 came out, and they only now got around to it. And that chapter lacks references for an entire section. That is not a good guide.
Make it a living document and keep it continuously updated with either expanded or deepened coverage, kept up to date with what's been learned in the industry. Then it will be useful. Otherwise, just go to Wikipedia and you'll get a better resource.
