### relax version 3.1.7.

*Item posted by Edward d Auvergne <bugman> on Mon Mar 17 15:53:07 2014.*

### Description

This is a minor feature and bugfix release which includes improvements to the relaxation dispersion chapter of the manual and the addition of new infrastructure for R1rho data handling in the dispersion analysis. More details are given below.

### Download

The new relax versions can be downloaded from http://www.nmr-relax.com/download.html. If binary distributions are not yet available for your platform and you manage to compile the binary modules, please consider contributing these to the relax project (described in section 3.6 of the relax manual, http://www.nmr-relax.com/manual/relax_distribution_archives.html).
