**Full Changelog**: https://github.com/Unidata/MetPy/compare/v1.1.0...v1.2.0

This is the first feature release since 1.0.

Highlights
* Added classes to read a variety of data in GEMPAK-formatted files
* Added `showalter_index` calculation
* Added `PlotGeometry` to the simplified plotting interface, which makes it easy to plot a variety of geospatial data (e.g. SPC convective outlooks or NHC hurricane wind swaths in geojson format). See [this notebook](https://gist.github.com/23ccozad/8c5ee73731c466be2ed00817aabd792d) for examples.
* Significantly improved METAR parser to output both the visibility and remarks part of the reports, as well as better handle more weather codes (like 'FU')
* Improvements to simplified plotting interface including better notebook tab completion, support for controlling font size, and GEMPAK-like zooming on areas (e.g. '+us')
* Improved detection of problematic soundings in calculations
* Dropped support for Python <3.7 and NumPy <1.17
* Reduced the time it takes to import `metpy.io`
* Fixed up a variety of unit issues in calculations
