 - Make the private basis classes public (`assembly.expression.Basis`, `assembly.expression.BasisField` and `assembly.expression.BasisArray`) as especially their docstrings are useful to understand how a *Basis* is created on a field.
 - Remove material parameter keyword-arguments in the `function()`-, `gradient()`- and `hessian()`-methods of the core constitutive material formulations. This removes the ability for temporary material parameters in `LinearElastic(E=None, nu=0.3).gradient(x, E=1.0)`, use `LinearElastic(E=1.0, nu=0.3).gradient(x)` instead. This affects the material formulations `LinearElastic`, `LinearElasticPlaneStrain`, `LinearElasticPlaneStress`, `LinearElasticLargeStrain`, `NeoHooke` and `NeoHookeCompressible`. `None` is still supported for the material parameters of `NeoHooke` and `NeoHookeCompressible`.
 - Remove `LinearElasticPlaneStrain` from the top-level package namespace because this should only be used with `Field(region, dim=2)`. The preferred method is to use `FieldPlaneStrain(region, dim=2)` and the default `LinearElastic`. `LinearElasticPlaneStrain` remains available in `constitution.LinearElasticPlaneStrain`.
+- Rename `Mesh.as_pyvista()` to `Mesh.as_unstructured_grid()` and add `Mesh.as_pyvista()` as alias.
 
 ### Deprecated
 - Deprecate `SolidBodyGravity`, `SolidBodyForce` should be used instead.
