No, dolfin-stable keeps the kernel stable and is for module
development. The "dolfin" repository is for kernel development, and
should keep the modules stable to make sure nothing breaks which has
previously worked.

I removed all except navierstokes, elasticity-updated and plasticity
(the ones I didn't mark as obsolete before). I'll put it back since
you need it though.

This is what I mean with differentiating between pure equations and
solvers though. Does the convection-diffusion equation really require
a specialized solver? Can't it be implemented in a general way using
the TimeDependentPDE interface we have? Note that it also exists in
src/demo/pde/convection-diffusion.
