Sat Feb  8 20:34:17 UTC 2020 - Stefan Brüns <stefan.bruens@rwth-aachen.de>

- Update to 2019.1.0
  * Remove scripts
  * Remove LaTeX support (not functional)
  * Add support for complex valued elements; complex mode is chosen
    by compute_form_data(form, complex_mode=True) typically by a
    form compiler; otherwise UFL language is agnostic to the choice
    of real/complex domain
- Update to 2018.1.0
  * Remove python2 support
- Update to 2017.2.0
  * Add geometric quantity CellDiameter defined as a set diameter
    of the cell, i.e., maximal distance between any two points
    of the cell; implemented on simplices and quads/hexes
  * Rename internally used reference quantities
    (Cell|Facet)EdgeVectors to Reference(Cell|Facet)EdgeVectors
  * Add internally used quantites CellVertices,
    (Cell|Facet)EdgeVectors which are physical-coordinates-valued;
    will be useful for further geometry lowering implementations
    for quads/hexes
  * Implement geometry lowering of (Min|Max)(Cell|Facet)EdgeLength
    for quads and hexes
- Update to 2017.1.0
  * Change PyPI package name to fenics-ufl.
  * Add the DirectionalSobolevSpace subclass of SobolevSpace. This
    allows one to use spaces where elements have varying continuity
    in different spatial directions.
  * Add sobolev_space methods for HDiv and HCurl finite elements.
  * Add sobolev_space methods for TensorProductElement and
    EnrichedElement. The smallest shared Sobolev space will be
    returned for enriched elements. For the tensor product
    elements, a DirectionalSobolevSpace is returned depending on
    the order of the spaces associated with the component elements.
- Remove python3-devel build dependency, package is noarch.

- updated to version 2016.2.0 [2016-11-30]
  * Add call operator syntax to Form to replace arguments and
    coefficients. This makes it easier to e.g. express the norm
    defined by a bilinear form as a functional. Example usage:
      # Equivalent to replace(a, {u: f, v: f})
      M = a(f, f)
      # Equivalent to replace(a, {f:1})
      c = a(coefficients={f:1})
  * Add call operator syntax to Form to replace arguments and coefficients:
     a(f, g) == replace(a, {u: f, v: g})
     a(coefficients={f:1}) == replace(a, {f:1})
  * Add @ operator to Form: form @ f == action(form, f) (python 3.5+ only)
  * Reduce noise in Mesh str such that print(form) gets more short and readable
  * Fix repeated split(function) for arbitrary nested elements
  * EnrichedElement: Remove +/* warning
    In the distant past, A + B => MixedElement([A, B]).  The change that
    A + B => EnrichedElement([A, B]) was made in d622c74 (22 March 2010).
    A warning was introduced in fcbc5ff (26 March 2010) that the meaning of
    "+" had changed, and that users wanting a MixedElement should use "*"
    instead.  People have, presumably, been seeing this warning for 6 1/2
    years by now, so it's probably safe to remove.
  * Rework TensorProductElement implementation, replaces OuterProductElement
  * Rework TensorProductCell implementation, replaces OuterProductCell
  * Remove OuterProductVectorElement and OuterProductTensorElement
  * Add FacetElement and InteriorElement
  * Add Hellan-Herrmann-Johnson element
  * Add support for double covariant and contravariant mappings in mixed elements
  * Support discontinuous Taylor elements on all simplices
  * Some more performance improvements
  * Minor bugfixes
  * Improve Python 3 support
  * More permissive in integer types accepted some places
  * Make ufl pass almost all flake8 tests
  * Add bitbucket pipelines testing
  * Improve documentation
 2016.1.0 [2016-06-23]
  * Add operator A^(i,j) := as_tensor(A, (i,j))
  * Updates to old manual for publishing on fenics-ufl.readthedocs.org
  * Bugfix for ufl files with utf-8 encoding
  * Bugfix in conditional derivatives to avoid inf/nan values in generated
    code. This bugfix may break ffc if uflacs is not used, to get around
    that the old workaround in ufl can be enabled by setting
    ufl.algorithms.apply_derivatives.CONDITIONAL_WORKAROUND = True
    at the top of your program.
  * Allow sum([expressions]) where expressions are nonscalar by defining expr+0==expr
  * Allow form=0; form -= other;
  * Deprecate .cell(), .domain(), .element() in favour of .ufl_cell(),
	.ufl_domain(), .ufl_element(), in multiple classes, to allow
	closer integration with dolfin.
  * Remove deprecated properties cell.{d,x,n,volume,circumradius,facet_area}.
  * Remove ancient form2ufl script
  * Add new class Mesh to replace Domain
  * Add new class FunctionSpace(mesh, element)
  * Make FiniteElement classes take Cell, not Domain.
  * Large reworking of symbolic geometry pipeline
  * Implement symbolic Piola mappings
- migrated package to python3
