   * added missing casting methods to convert esri to uniform and uniform to rectilinear (when you want to use point data on an esri-grid, you can cast it to uniform first)
   * added `axes_attributes` also to unstructured grids
 * Grid method `compatible_with` now has a `check_location` argument to optionally check data location (!280)
+* added `Mask` enum with two options: (!286)
+  * `Mask.FLEX` for flexible masking
+  * `Mask.NONE` to explicitly use plain numpy arrays
+* added `mask` attribute and init-arg to `Info` : can be a `Mask` value or a valid mask for `numpy.ma.MaskedArray` (!286)
+* `data.tools.prepare` now applies masks to data if set in `Info` object (!286)
+* `ARegridding` now has a `out_mask` arg (!286)
+* `RegridNearest` and `RegridLinear` now support explicitly masked data (input doesn't have `Mask.FLEX`) (!286)
+* adapters now have an `in_info` property (!286)

+### Bug fixes

+* cells for structured grids in 3D are now created correctly (no negative Volume in VTK/ESMF) (!286)
