I've updated and I'm not having any problems... Yet.

What could possibly go wrong, especially since it is downloaded from the internet?

Seriously, I have not heard of a significant problem.

As a VAR, we have not had many calls regarding 2018 as an issue so I wouldn't worry too much. After all it is the best release ever!

For specific assemblies, the opening time decreases by about 40% compared to SW 2017, all settings remaining the same.

No one has any explanation for this phenomenon.
