API Changes
* `potential_vorticity_baroclinic` was changed to take all 3D variables, with dimensions ordered: vertical, y, x.

Highlights
* MetPy has gained a simplified plotting interface designed to mimic that of GEMPAK. It uses a handful of objects on which users set attributes to values to control the plot, requiring data in an xarray `DataArray` or `Dataset`. See MetPy's [plotting examples](https://unidata.github.io/MetPy/latest/examples/index.html#plotting) for more information.
* MetPy's xarray accessor now has its own versions of `loc` and `sel` that accept unit-ed values.
* Added an n-point soothing function
* `moist_lapse` and `dry_lapse` now accept an arbitrary starting (reference) pressure value.
* `potential_vorticity_baroclinic` now works with data either on isobaric or isentropic surfaces.
* MetPy now has state borders that match the boundaries of the county borders.
* `SkewT` instances can now be created at an arbitrary rectangular location within a figure.
* MetPy's calculations have been adjusted so that the values of constants can be overridden by changing the values in the `constants` module.

API Changes
* Renamed `get_wind_speed` to `wind_speed`; the old name is still available but is deprecated and will be removed in 0.12
* Renamed `get_wind_dir` to `wind_direction`; the old name is still available but is deprecated and will be removed in 0.12
* Renamed `get_wind_components` to `wind_components`; the old name is still available but is deprecated and will be removed in 0.12

Highlights

* Added support for cross-sections along arbitrary lat/lon paths
* Added `parcel_profile_with_lcl` to compute the parcel profile and return values for the parcel profile, as well as the ambient pressure, temperature, and dew point that includes the lcl
* Fixed corner case problems in some thermodynamic calculations by using parcel profiles including the LCL
* Added function to get a matplotlib color from a GEMPAK color number
* Added CartoPy map feature for U.S. counties
* `get_test_data` will now automatically download and cache data files if the user is not running a git checkout of MetPy. This makes all of our test/example data much more easily available.
* Added `smooth_gaussian`, which smooths a grid using a Gaussian distribution-shaped kernel; this is an analog of GEMPAK's `gwfs`
* Fixed error reading newer NEXRAD Level 2 files
