0.9.1

0.7.1
- Handle setting quadrature degree when it is set to None in UFL form
- Added demo: HyperElasticity.ufl
0.7.0
- Move contents of TODO to: https://blueprints.launchpad.net/ffc
- Support for restriction of finite elements to only consider facet dofs
- Use quadrature_order from metadata when integrating terms using tensor
representation
- Use loop to reset the entries of the local element tensor
- Added new symbolic classes for quadrature optimisation (speed up compilation)
- Added demos: Biharmonic.ufl, div(grad(v)) term;
ReactionDiffusion.ufl, tuple notation;
MetaData.ufl, how to attach metadata to the measure;
ElementRestriction.ufl, restriction of elements to facets
- Tabulate the coordinates of the integration points in the tabulate_tensor()
function
- Change command line option '-f split_implementation' -> '-f split'
- Renaming of files and restructuring of the compiler directory
- Added option -q rule (--quadrature-rule rule) to specify which rule to use
for integration of a given integral. (Can also bet set through the metadata
through "quadrature_rule"). No rules have yet been implemented, so default
is the FIAT rule.
