v0.8.1

v0.8.1 is a small update to v0.8.0 that adds two planned changes that got overlooked:

• The nu kwargs and member of Matern is now called smoothness, and
• Ancillary codes like performance/benchmark.py are updated to use the new API.

What's Changed

• update extraneous bits with new API by @bwpriest in #197
• replaced "nu" with "smoothness" throughout by @bwpriest in #198
