Unraid 7.3 stable has landed, with 7.3.1 right behind it. Internal boot, TPM-based licensing, a much better VM CPU pinning view, a new Docker fixed MAC address field, SR-IOV on Intel B-series cards, and a stack of ZFS visibility improvements. There's a lot to unpack, so I've put it all in one video.
In this video I walk through everything new across the 7.3 branch, comparing 7.2 to 7.3.1 side by side wherever it helps. I cover internal boot (and the surprise USB controller passthrough win that comes with it), TPM-based licensing and what's actually stored in the TPM (spoiler, not your license), the dashboard tour with kernel version bumps and the hardware they unlock, the new ZFS health visibility, the Docker MAC address field with the MACVLAN vs IPVLAN gotcha you'll want to know about, the new VM CPU pinning view, and a hands-on demo of SR-IOV on an Intel Arc Pro B50.
