* Peak intensity errors can now be calculated when using volume integration and replicated spectra ([https://gna.org/bugs/?17457 bug #17457]).
* Failure of the prolate diffusion tensor in model-free analysis - if the tensor is initialised with Da = 0, the tensor is converted to being oblate. This was introduced in relax version 1.3.6.
* relax can now operate without scipy being installed.
* Updated four model-free optimisation system tests to pass under 32-bit Linux.
* Made the N_state_model.test_pcs_fit_zero_pos system test less stringent so it passes on 32-bit Linux.
* The model_free _model_setup() method should handle no model-free model being set when reading relax 1.2 results files ([https://gna.org/bugs/?17417 bug #17417]).
