This is mainly a bug fix version of the 3.1 series. All tickets solved are described below.

# Noticeable fixed issues that may affect the results obtained with previous versions

Ticket #256 reported that the scalar product of two unsymmetric tensors was not properly computed.

This may affect single crystal finite strain computations to a limited extent, as the Mandel stress tensor is almost symmetric.

# Tickets fixed

## Ticket #245: Example generated with the zmat behaviour misses the **parameters section

For more details, see: https://sourceforge.net/p/tfel/tickets/245/

## Ticket #199: The wrapping of the setParameter methods of the mtest::Behaviour class is missing in the python bindings

The following methods are now available:

• setParameter
• setIntegerParameter
• setUnsignedIntegerParameter
