I got very excited by the Holiday Specials sent out over email this morning, but found little information about what exactly the plan included. After talking to @mwoodworth33 I got some answers, and now want to share it with all of you.
Unlimited Private Projects
Public Team Collaboration
Access to Verified Parts
… and every else listed in the starter plan
Private Team Collaboration
3D Preview (though that might maybe no promises change in the future)
Parts Concierge (though anyone can currently buy a 10 pack for $150 if you’d like them to take care of some tricky parts)
The forthcoming Simulation feature (though that might also get an a la carte option)
So this plan is basically the Professional Plan minus a couple laborious/premium features. I was also told the plan would be grandfathered into new features as they come out (though laborious/premium features will probably continue to cost extra).
