  - mro/hideal2pds app now writes the correct SAMPLE_BIT_MASK values to the output label. [#3978](https://github.com/USGS-Astrogeology/ISIS3/issues/3978)
 
-  - For Histograms in ISIS, updated the math for calculating what bin data should be placed in and the min/max values of each bin to be more intuitive. In addition, the output of hist and cnethist were changed to display the min/max values of each bin instead of the middle pixel's DN. [#3882](https://github.com/USGS-Astrogeology/ISIS3/issues/3882)
