I've upgraded my projects from 0.10 to 0.11 according to:
https://github.com/duct-framework/duct/blob/master/UPGRADING.md#011-from-010
In comparison with the newly generated 0.11 project skelton there are few more differences that I have not noticed in the documentation:
project.clj (marked red):

dev.clj:

I do not know, if all differences are required.
