<onlyinclude>This release introduces new features and fixes a number of important bugs. The most significant feature is the consistency testing of relaxation data from different field strengths using the J(0), F_eta and F_R2 values [Morin and Gagné, 2009][Fushman et al., 1998]. Important bugs which have been fixed include the failure of Monte Carlo simulations when model-free model 'm0' is encountered causing the parameter errors for all subsequent residues to be zero, the failure of reading of Art Palmer's Modelfree 4 'mfout' file, and the handling of missing structural data. For a full description of the additions and fixes, please see below.</onlyinclude>== Description ==

=== Features == * Consistency testing has been added allowing datasets recorded at different magnetic fields to be checked using the consistency function values J(0), Feta, and FR2.* The 'full_analysis.py' script [d'Auvergne and Gooley, 2008] can now perform a model-free analysis in the absence of structural data.=

=== Changes ===
<section begin=changes/>
* Better support for MS Windows Vista in the scons build system and the relax introduction.
* A file listing the unresolved residues is no longer necessary for running the 'full_analysis.py' script.
* A few small documentation additions and fixes.
<section end=changes/>
=== Bugfixes ===
<section begin== Bugfixes ==bugfixes/>* The parameters Dpar D<sub>∥</sub> and Dper D<sub>⊥</sub> are now properly checked upon initialisation of this spheroidal diffusion tensor.
* Initialisation of an empty diffusion tensor to the default values of zero now works.
* The default value of the Iinf I<sub>∞</sub> relaxation curve fitting parameter can now be set.* Fix for the complete failure of the reading in of Art Palmer's Modelfree 4 [[Modelfree4]] '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 [http://www.nmr-relax.com/manual/relax_data_display.html 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[[Modelfree4]]'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.
