Avid is going prescription only..
I only just noticed this one, but it was announced in May. Avid have been doing prescriptions and perpetual (buy once and never have to pay again) licences for a few years but they have now announced they will stop doing perpetual licences this year. They are phasing it out slowly; they will stop selling new perpetual licences from the end of this year but carry on selling upgrades to people who have already bought a perpetual licence.
The last perpetual licence upgrade will finish at the end of 2025 and after that they will only update for the subscription version.
