It is all-new.
With the Ubuntu development reorganization, it has been decided to expand the scope of Behind MOTU interviews beyond the MOTU team, and onto the larger Ubuntu Development Team.
The new Behind the Circle website features more than just a visual refresh. The former maintainer, Daniel Holbach, has handed the reins to the team of Maia Kozheva, Nigel Babu, and David Futcher. With the new authors, you can expect a number of new interviews with Ubuntu developers appearing in the near future!
