[Robert Cimrman]

I am pleased to announce release 2009.4 of SfePy.

Description
-----------

SfePy (simple finite elements in Python) is a software, distributed
under the BSD license, for solving systems of coupled partial
differential equations by the finite element method. The code is
based
on NumPy and SciPy packages.

New documentation site: http://docs.sfepy.org/doc

Many thanks to Logan Sorenson for the new documentation contents, and
Vladimir
Lukes for setting up the server.

Highlights of this release
--------------------------
- unified handling of user-defined functions (for defining subdomains,
  heterogeneous material properties, boundary conditions etc.)
- greatly improved postprocessing and visualization capabilities,
namely:
  - support for file sequences (evolutionary simulations)
  - animations (using ffmpeg)
  - automatic scalar bars
  - sfepy_gui.py: Mayavi2-based GUI to launch simulations

Major improvements
------------------
Apart from many bug-fixes, let us mention:
- quasistatic time stepping
- graphical logging:
  - dynamic adding of data groups (new axes) to Log and
ProcessPlotter
- linear algebra:
  - reversed Cuthill-McKee permutation algorithm, graph in-place
permutation
- setting of parameter variables by a user-defined function
- new tests and terms
