Using newer compiler versions and the optimizer gives gas optimizations and additional safety checks for free!
The advantages of versions 0.8.* over <0.8.0 are:
0.8.0 (can be more gas efficient than some
library based safemath).0.8.2, leads to cheaper runtime gas.
Especially relevant when the contract has small functions. For

Lenovo messed up with the X1E and P1 Gen 1 versions (and maybe later generations) in that the system boots with a thermal limit (aka Tjunction or tjmax) set to 82C (some report 80C). What this means is that regardless of power draw or under-volting settings, when your CPU hits 82C, it will drop the frequency down to the "Configurable TDP-down" frequency, or even lower. It will also may limits the system power draw.
