* Initialisation of an empty diffusion tensor to the default values of zero now works.
* The default value of the Iinf relaxation curve fitting parameter can now be set.
* Fix for the complete failure of the reading in of Art Palmer's Modelfree 4 'mfout' results file ([https://gna.org/bugs/?8997 see bug #8997]).* Fix for a rare ZeroDivisionError during Monte Carlo simulations ([https://gna.org/bugs/?11004 see bug #11004]).* relax no longer fails if XH bond vectors cannot be extracted from a PDB file ([https://gna.org/bugs/?11378 see bug #11378]).* The relax_data.display() user function no longer fails ([https://gna.org/bugs/?11383 see bug #11383]).* The selection of model-free model 'm0' causes Monte Carlo simulations to fail resulting in zero errors from that residue onwards ([https://gna.org/bugs/?11476 see bug #11476]).* Another column fusion bug in Modelfree 4's 'mfout' results file can be handled ([https://gna.org/bugs/?11483 see bug #11483]).
* Optimisation fix - the steady-state NOE value, gradient, and Hessian is now properly calculated when an order parameter of exactly 0.0 is encountered.
