<onlyinclude>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 1.2.5 ([https://gna.org/bugs/?7587 bug #7587]).

<section begin= Download description/>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 τ<sub>m</sub> 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.<section end=description/>

<section begin=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).
