Introduction on website is not working

[noppelmax]

Hey,

i tried to run the introduction published on the website in my notebook:

import geoviews as gv
import geoviews.feature as gf
import xarray as xr
from cartopy import crs

gv.extension('bokeh', 'matplotlib')

(gf.ocean + gf.land + gf.ocean * gf.land * gf.coastline * gf.borders).options(
    'Feature', projection=crs.Geostationary(), global_extent=True, height=325
).cols(3)

and i just get the following error:

You either need to downgrade cartopy or upgrade to a geoviews dev release. A real geoviews release compatible with latest cartopy will be released over the next couple of days.

GeoViews 1.6.0 has been out for 2 weeks now, and 1.6.1 will follow shortly.
