dolfin (2019.2.0~legacy20230609.8b85e9d.ar-1) unstable; urgency=medium

  * UFL 2023 is no longer compatible with legacy dolfin. The last
    compatible UFL version 2022 is now provided separately as
    ufl_legacy (python3-ufl-legacy). dolfin now uses ufl_legacy.
    Depending on how you use dolfin and ufl, you may need to update
    scripts, e.g. replace
      import ufl
    with
      import ufl_legacy as ufl
    or replace
      from ufl import FunctionSpace
    with
      from ufl_legacy import FunctionSpace
    If you use ufl classes from the dolfin namespace rather than the ufl
    namespace, for instance `from dolfin import *; V=FunctionSpace(mesh,el)`
    rather than `import ufl; V=ufl.FunctionSpace(mesh,el)`, then no code
    changes should be needed.
