Ubuntu 20.04 arrives with Linux 5.4 kernel and WireGuard VPN

It's mentioned in the article too, but also big: zfs support.

I've been _loving_ zfs since I switched a few months back. The big wins: easy and fast to backup (don't have to wait for rsync to check every file, and atomic snapshots mean less worry about backing up an inconsistent set of files) and even bigger are just snapshots themselves. Makes it _so_ easy to back out a failed upgrade or anything else that breaks.

Isn’t WireGuard from 5.6?
