ufl (1:2022.2.0-3) experimental; urgency=medium At version 2023.1.0, ufl (supporting next-generation ffcx and dolfinx) became incompatible with legacy ffc and dolfin. For this reason the legacy version ufl 2022.2.0 is now packaged separately as python3-ufl-legacy in order to continue supporting ffc and dolfin. The python module name has been changed from ufl to ufl_legacy. The python3-dolfin and python3-ffc packages have been patched to match this change. The dolfin module should continue to run without requiring changes to user scripts. However if your own scripts use the legacy ufl python module directly, you will need to update them to use ufl_legacy instead. All ufl import statements will need to be updated to ufl_legacy. That is, import ufl can be changed to import ufl_legacy as ufl requiring no further changes in the use of the ufl object. Any explicit imports must likewise be updated e.g. change from ufl import product to from ufl_legacy import product -- Drew Parsons Mon, 16 Jan 2023 02:08:56 +0100
