That change was, as far as I can tell, it was done without any prior announcement (it is announced on the new website). Unfortunately, I had been trying over last few days to figure out the best way to move my currently partially self-hosted setup to ProtonMail, and the only feasible way to do so would likely have been with the Visionary plan. ProtonMail's sudden removal of it means that I likely won't be able to switch to them, and will likely end up removing my current Professional plan. With its removal, there is no non-business plan with multiple mailboxes. It also appears that the ability to pay additional fees per item for extra custom domains, addresses, and other features has been removed. As such, if you need more than what the largest plan offers on these (eg, you need what the old Visionary plan offered), this now appears impossible.
