Version 0.10 (January 17, 2014)

We are very pleased to announce that Andrew Dawson was added to the cartopy core development team. In this release Andrew has single-handedly implemented comprehensive vector transformation and visualisation capabilities, including:

• The ability to transform vector fields between different coordinate reference systems via the transform_vectors() CRS method.

• GeoAxes.quiver and GeoAxes.barbs for arrow and barb plotting. More information is available at Vector plotting.

• A regridding function for “regularising” a vector field in the target coordinate system. See also cartopy.vector_transform.vector_scalar_to_grid(). Both quiver() and barbs() accept the regrid_shape keyword to trigger this behaviour automatically.

• GeoAxes.streamplot adds the ability to draw streamlines in any projection from a vector field in any other projection.
