c++ – Is TC++PL 4th Edition by Bjarne Stroustrup outdated?

First of all, I hope this question doesn’t fall under “Asking For Books Recommendation” Category.

Since TC++PL covers C++11, it is 3 revisions old (C++14, C++17, C++20), the ISO group is working on C++23, and I think a 5th revision won’t be published anytime soon. So is it outdated?
