* 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])
* If optimisation returns an infinite value or a NaN value, these are now caught and a RelaxError thrown. ([https://gna.org/bugs/?6503 bug #6503], [https://gna.org/task/?3621 task #3621])
* The [http://www.nmr-relax.com/manual/NOE_script_mode_NOE_calculation.html &sigma(;<sub>NOE) </sub> equations of Chapter 8 of the manual] have been fixed. ([https://gna.org/bugs/?7402 bug #7402])
* Files containing relaxation data not consisting of exactly 4 columns will now be read. ([https://gna.org/bugs/?7583 bug #7583])
* Model-free results files from relax versions prior to [[relax 1.2.5|1.2.5]] are now properly read. ([https://gna.org/bugs/?7587 bug #7587])
