What is the difference between Werkstatt-01 (2020) and the 2014 Moogfest edition?

This production run of Werkstatt-01 features the same 100% analog design of the 2014 Moogfest Werkstatt-01. The key difference is that the 2020 Werkstatt-01 has been updated to accept a CV Gate Input. *Because of this difference, the current CV Expander is not interchangeable with the 2014 CV Expander.
