Since C++11, the ISO committee has been aiming for a new standard release every 3 years. So far, they've kept this cadence up. I don't recall if C++20 is actually out yet, but I know the feature set was finalized last year, if not out yet, it's probably just due to editorial issues (I've not been using C++ for work the last few years, so my knowledge might be a bit dated).
