-----

- 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.
- Remove support for old style .form files/format

------------------

- Experimental support for UFL, supporting both .form and .ufl
- Moved configuration and construction of python extension module to ufc_module

------------------

- Initial work on UFL transition
- Minor bug fixes
- The version of ufc and swig is included in the form signature
- Better system configuration for JIT compiled forms
- The JIT compiled python extension module use shared_ptr for all classes

------------------

- Update DOLFIN output format (-l dolfin) for DOLFIN 0.9.0
- Cross-platform fixes for test scripts
- Minor bug fix for quadrature code generation (forms affected by this bug would not be able to compile
- Fix bug with output of ``*.py``.
- Permit dot product bewteen rectangular matrices (Frobenius norm)

------------------

- New operator skew()
- Allow JIT compilation of elements and dof maps
- Rewrite JIT compiler to rely on Instant for caching
- Display flop count for evaluating the element tensor during compilation
- Add arguments language and representation to options dictionary
- Fix installation on Windows
- Add option -f split_implementation for separate .h and .cpp files

------------------

- Remove default restriction +/- for Constant
- Make JIT optimization (-O0 / -O2) optional
- Add in-memory cache to speed up JIT compiler for repeated assembly
- Allow subdomain integrals without needing full range of integrals
- Allow simple subdomain integral specification dx(0), dx(1), ds(0) etc
