Today (27-Mar-2014) is the official release day for AutoCAD 2015! All restrictions on the beta testers are lifted, and for those of you on Subscription be sure to check your account now for the available downloads.
AutoCAD Civil 3D and many of the verticals will be released in the weeks ahead. But for those who like to get an early jump on the newest stuff (and we know who we are!) the basic version of AutoCAD (and LT) 2015 is now ready for you to install, play with, and provide feedback. Be sure to use the Autodesk Community Forums if you have questions or need help.
I'll have more to say once I get mine up and running. Enjoy!
