I've installed squeezelite using my tutorial on this version, and everything seems to work (haven't tested wifi yet).
One thing was a bit different compared to earlier versions, I had to manually load snd-bcm2835 to make the onboard sound device work.
In the end I've used this command to make "stick" after a reboot:
echo "/sbin/modprobe snd-bcm2835" >> /opt/bootlocal.sh
sudo filetool.sh -b
I am not saying this is a problem or bug, I understand it if you left it out on purpose. It's just something I noticed.
