Edit : in the meantime, Steinberg made an announcement that answered my question about the new licensing system. Thank you.

you’re laughing but Steinberg have announced they’re going dongle-less. Tom

I’m curious if Steinberg also plans to update their older plugins respectively. At least I wouldn’t want to keep the dongle around, just to be able to use Halion Symphonic Orchestra…

I saw the announcement after! Great!
