v1.6.0

Highlights

• Consistently use the WMO definition of relative humidity across calculations
• New calculations: wet bulb potential temperature, Corfidi MCS motion, DCAPE, and Galvez-Davidson Index
• Improvements for using isentropic interpolation with xarray data not natively on pressure surfaces (like WRF output)
• Support for specifying line stroke width in simplified plotting interface
• Support for controlling more style options for map layers in simplified plotting interface
• Support for rotated latitude longitude projection
• Support for Python 3.12
• Many bug fixes and clean ups
