Is Radsystems Studio still alive?

Radsystems Studio seems very good product, but since both Laravel 7 and php 7.4 have finished their development cycle, I have a few questions for developers:
Does it make sense to invest time and money in RadSystems?
Is an upgrade to Laravel 10.x and php 8.x planned?
Is there a roadmap for the project?
Is Radsystems still alive?
