C++11 was quite a break, C++14 very minor, C++17 a little bit more, but not as major. C++2x is doing a lot of changes, but I haven't seen much of it in the embedded world yet. Mostly because C++17 is still considered new-ish in most safety-critical realms. But say you have some C++<11 experience I think you would need a few weeks to get up to speed max.
