Docs downloaded from the CircleCI build.

curl -H "Circle-Token: $CIRCLE_TOKEN" https://circleci.com/api/v1.1/project/github/SciTools/cartopy/2856/artifacts \
   | grep -o 'https://[^"]*' \
   | wget -x -nH --verbose --header "Circle-Token: $CIRCLE_TOKEN" --input-file -

Followed the instructions in the base repo and removed the .build_info file included in the download.

I don’t know anything about how this is generated, but it looks like the wrong release number has snuck in somehow. See e.g. the top of the API page.

New docs looking good though - nice and clean.

Ah, this was wrong for 0.19.0 too, I think. @greglucas you should have pulled from the CircleCI build for the tag, but it seems we have excluded builds for tags.

[QuLogic]

I pushed a v0.20.x branch based on the tag, which maybe will trick CircleCI into a build without getting the version number wrong.

@rcomer, looks like the new version worked: https://scitools.org.uk/cartopy/docs/latest/reference/index.html

Let us know if you find anything else missing/wrong!
