From other posts on the forum, it seems the new symbolic engine is FriCAS. It saves PTC from having to license technology from Maplesoft or Mathworks, which they were previously doing. I doubt the other companies even wanted to renew their deal with PTC, but who knows. Maybe PTC just didn't want to give money to competitors, and who could blame them. Others have posted the new engine has some problems. So time will tell how this will play out.
I'd like to see PTC sell Mathcad to Maplesoft. Then it could get back to being like it used to be.
