Minimum Premiere pro version required for encodeProjectItem

Hi All,

What is the minimum Premiere pro version required to support app.encoder.encodeProjectItem in extension panel?

Our panel uses this method, and its throwing error "ReferenceError: app.encoder.encodeProjectItem is not a function" in Adobe Premiere pro 2015.2 [9.2.0(41) build]

Thanks and Regards,

Anoop NR
