*****************************
2009-April-13
Release of SCRaytrace V 2.2.
*****************************
New features:
- Implement ModelPosition class to deal with positioning of the models.
- Implement extra positioning parameters for the models.
- Use a common ChangeCoordtoDensity function to calculate the position of a point into the model basis.



*****************************

Release of SCRaytrace V 2.1.3
*****************************
Bug fixes:
- Fix quiet mode in the scene class.



*****************************
2009-April-02
Release of SCRaytrace V 2.1.2
*****************************
Bug fixes:
- Fix quiet mode in rtthread and buildcloud.



*****************************
2009-March-24
Release of SCRaytrace V 2.1.1
*****************************
Bug fixes:
- Fix model 26: density cube with tri-linear interpolation.



****************************
2009-March-06
Release of SCRaytrace V 2.1.
****************************
New features:
- Implement neshift to allow translating the model in its own coordinate system. The class Cbasis has been slightly modified too for this purpose.

Bug fixes:
- Fix calculation of brightness for the UV renderer.
- Fix problem of integration in front of behind the Solar disk.



****************************
2009-February-09
Release of SCRaytrace V 2.0.
****************************
New features:
- Use of boost thread for multi-threading the raytracing. Increase significantly the processing speed on multi-core machines.
- Few new models where implemented: see the model list in the source code documentation for more details.

Refactoring:
- Change CModel::Density method prototype.
- Use double precision for computation of Thomson scattering geometric coefficients to avoid weird values when far away from the Sun.

Miscelaneous:
- Update and clean up source code documentation.
