2.3	New environment added: cellSizeProjectionMethod
2.0	Two new parameters added: method z_unit The method parameter allows you choose between the traditional planar method for performing the calculations, and the new geodesic method. When using the geodesic option: A new z_unit parameter is available, which allows you to specify the linear unit of the vertical z-values if it is not already defined in the coordinate system of the input. If a suitable GPU device is available on your system, greater performance will come as a result of the calculations being GPU accelerated. The behavior for how NoData cells and boundary cells are handled was changed. At least seven of the eight cells neighboring the processing cell must have a value, otherwise the output will be NoData. Cells in the outermost rows and columns of the output raster will be NoData.

3.0	Two new parameters added: extraction_area analysis_extent
2.3	New environment added: cellSizeProjectionMethod
2.2	There were some changes in the default environment behavior, as follows: The tool will now use the in_raster as the default snap raster. This will improve the accuracy of the output by ensuring the correct alignment of the feature mask with the value raster. If the Mask input is a feature, the in_raster will be used for setting the cell size and the snap raster for the analysis environment. If the Mask input is a raster, the tool will compare the cell size of it to that of the in_raster, and use the one with the largest value as the cell size of the operation.

2.0	Two new parameters added: method z_unit The method parameter allows you choose between the traditional planar method for performing the calculations, and the new geodesic method. When using the geodesic option: A new z_unit parameter is available, which allows you to specify the linear unit of the vertical z-values if it is not already defined in the coordinate system of the input. If a suitable GPU device is available on your system, greater performance will come as a result of the calculations being GPU accelerated. The behavior for how NoData cells and boundary cells are handled was changed. At least seven of the eight cells neighboring the processing cell must have a value, otherwise the output will be NoData. Cells in the outermost rows and columns of the output raster will be NoData.
