I got this warning:
*** Warning: Parameters *_domains of assemble has been deprecated in DOLFIN version 1.4.0.
*** It will be removed from version 1.6.0.
*** Parameter *_domains of assemble will be removed. Include this in the ufl form instead.
*** ----------------------
My general question: Is there a place/source where the correct usage of these features is tabulated ? The documentation and tutorials online obviously cannot keep pace with the changes.
