Yep, already started local builds/tests, new ISO is certainly needed with the huge amounts of updates. You can expect the first public test ISO to be up in 2-3 days.

2 months later

Yes, already build a few, just locally, tons of changes in Calamares, so thus far no use yet to upload for general testing. Expect one this week, with linux kernel 4.20.10.

Thanks for info. I damaged my system, while playing with new systemd. I will wait patiently.
