## 1.0.7 (August 23, 2012)

  • stats function on Base object that, for each variable, gives the mean, min, max and the variance,

  • full python Tecplot binary file reader and writer,

  • more treatments examples.

  • Antares does not use tvtk anymore for slice and iso-surface treatments, it uses vtk instead

## 1.0.6 (July 27, 2012)

  • node_to_cell function (for both structured and unstructured grid),

  • Window attributes, now use a zone_name attribute instead of the _parent attribute to know in which zone to work

  • Zone/Instant shape attribute (the attribute can now be set with just a = instead of using set_shape function)
