This is a major bug fix release. A number of important bugs have been fixed including the failure of model selection between global diffusion models when using the local tm models ([https://gna.org/bugs/?7616 bug #7616]), the failure of model elimination when the model '[[m0' ]] is used ([https://gna.org/bugs/?7226 bug #7226]), and the failure in the reading of old model-free results files from relax versions prior to [[relax 1.2.5|1.2.5]] ([https://gna.org/bugs/?7587 bug #7587]). Additional bug fixes are detailed below. New features include preliminary support for RNA/DNA data and support for the [http://www.nmr-relax.com/manual/grace_write.html grace.write user function] for reduced spectral density mapping.

* The 'angles.py' sample script no longer fails when residue specific relaxation data is missing (corrupt input data). ([https://gna.org/bugs/?7224 bug #7224])
* Prior to executing Modelfree4, Dasha, Molmol, Grace, or OpenDX, tests are run to determine if the binary exists, is executable, and is in the system path. ([https://gna.org/bugs/?7225 bug #7225])
* Model elimination when using the model-free model '[[m0' ]] no longer fails. ([https://gna.org/bugs/?7226 bug #7226])
* The strict checking of the Da and Dr diffusion tensor parameters has been relaxed to allow for optimisation imprecision. ([https://gna.org/bugs/?7297 bug #7297])
* The reading of Modelfree4 mfout results files no longer fails when residue specific relaxation data is missing (corrupt input data). ([https://gna.org/bugs/?7277 bug #7277])
