Specifically, it is highly recommended to update 2.6.0 or 2.6.1

Bug fixes:

Space go directly to the correspoding edit screen, again, as expected.

copied to the new course.
 - Link/Button to access Construction Space now added to Main Menu/Remote 
Control for Assistant Co-authors. 

 - Practice problems are marked as "not graded" in a course's table of
