This release improves compatibility for different operating systems including Unix, Mac OS X, and Windows. To achieve this, the make system has been replaced by the Sconstruct system. Both the [[Dasha]] and [[Modelfree4]] code has been significantly improved. A number of bugs have also been fixed including:
* The [http://www.nmr-relax.com/api/1.2/generic_fns.dasha-pysrc.html#Dasha.create_script automatically generated Dasha script] has been fixed. Previously the optimise command used was '<code>min all' </code> or '<code>lmin all'</code>. This is incorrect and the proper syntax is '<code>min m n' </code> or '<code>lmin m n' </code> where m is the first residue number while n is the last.
* The code of [http://www.nmr-relax.com/api/1.2/generic_fns.value-module.html generic_fns/value.py], [http://www.nmr-relax.com/api/1.2/generic_fns.diffusion_tensor-module.html generic_fns/diffusion_tensor.py], and [http://www.nmr-relax.com/api/1.2/specific_fns.model_free-module.html specific_fns/model_free.py] has been fixed to properly handle the local {{:tau_m}} parameter as well as the global {{:tau_m}} parameter.
