.. warning::

:term:`FiPy` 2 brings unavoidable syntax changes. Please see
:mod:`examples.updating.update1_0to2_0` for guidance on the changes that
you will need to make to your :term:`FiPy` 1.x scripts.

The significant changes since version 1.2 are:

- :class:`~fipy.variables.cellVariable.CellVariable` and
:class:`~fipy.variables.faceVariable.FaceVariable` objects can hold
values of any rank.

- Much simpler syntax for specifying
``Cell``\s for initial conditions and
``Face``\s for boundary conditions.

- Automated determination of the Péclet number and partitioning of
:class:`~fipy.terms.implicitSourceTerm.ImplicitSourceTerm` coefficients
between the matrix diagonal and the right-hand-side-vector.

- Simplified :class:`~fipy.viewers.viewer.Viewer` syntax.

- Support for the `Trilinos solvers`_.

- Support for anisotropic diffusion coefficients.
