I see that TurboFloat will be not valid for solo plan and basic plan, it is right ?
Yes. TurboFloat will only be available for the Plus, Premium and Max plans. It's also included with the self-hosted version of LimeLM. For all other plans there's a 10 floating license limit (so you can try TurboFloat and see if fits your needs).
If yes, it is a very bad new for a lot of customers...For exemple, i do not need to have 3000 activations just to use float lincenses. 😲
Floating licenses won't be needed by most customers. They're typically only needed by customers selling to large end-users buying many "seats" of software (corporations, universities, government agencies, etc.) For customers selling to these types of end-users, the Plus plan price is a negligible cost (especially considering the positive ROI -- return on investment -- of LimeLM).
