gcc 8.2! Being on gcc 4.8.5 for RHEL 7 instead of 4.9 was a minor pain point for some c++11 or newer libraries when developing. Nice to see them jump all the way to the 8.x series.
Also great to see xfs gain COW support in RHEL, they are working to make up (in features) for dropping btrfs with xfs. We'll see how stratis works out.
