A good source of information for what is new in C++ versions: https://www.modernescpp.com/index.php/thebigfour https://www.modernescpp.com/index.php/thebigfour That article covers the big four new features: - concepts - modules - coroutines - ranges library

Wow. I haven’t touched C++ in maybe 18 years or so. This actually looks somewhat high level. It mentions that modules will improve compilation times. How are compilation times these days? That was one of my least favorite aspects of C++ back in the day.

In general, I tend to wait less for my C++ builds than Rust ones.

  C++ compilers keep improving and compile times have gotten noticeably quicker for me, especially the linker step which used to take forever. It is possible to have a fast C++ build, but it still requires diligence, ie avoiding including massive headers everywhere & using lots of forward declarations etc. Many code bases don't do this so they end up with ~forever builds.
