it is a shame TC has been abandoned by its developers. I would be very much pleased if the development will get taken over by others to maintain that very much useful product.
Anyhow. I have looked around a little bit but did not find a real roadmap beside the information that a complete redesign and new setup aproach will be taken. This, I expect, will take 2-3 years to get ready. But what is in the meantime? There are some updates in functionality already necessary for the current release of TC, like UEFI-Support. The next windows release is also announced and what I experienced over the last years, an adjustment to new windows releases was always necessary, as far as I could see this as simple user only.
So - where is the roadmap?
Once I am confinced it will go on I will be willing to donate, as I also did for the former development team. Only small donations - but anyhow.
