20.0.6 (April 16, 2020) Bug-fix release in the 20.0.x series. This release fixes a bug for **phase-difference fieldmaps that are not in RAS+ orientation**. The bug presented as an error if the orientation was reordered relative to RAS+ (for example, AIL+) and the swapped dimensions were not of the same size. Otherwise, the bug introduced a poor masking of the phase difference map, and could be quite subtle if the original orientation was LAS+. Runs of fMRIPrep that used other susceptibility distortion correction (SDC) methods are not currently considered problematic. This bug affects all earlier versions of fMRIPrep, except for 1.5.10 and any future releases in the 1.5.x series. * FIX: Do not reorient magnitude images nipreps/sdcflows#98
