This Release includes

- Test Suite Restructure (174) which improved the ability to run and edit tests by breaking them out from single files into folders containing tests for specific parts of each submodule
- Metocean module added which can pull data from the wind_toolkit with 4 regions and 1-hr or 5-min data (187)
- Two Dolfyn Updates (169, 186) which address many bug fixes, clean up, and some feature expansion
- ADV skipped timesteps, max gap, and attributes
- error in integral length scale calculation
- error in despiking function
- move Reynolds stress and cross-spectral density calculations to ADV folder
- prevent inaccurate TKE calculation from ADCP velocity input
- Delft3D z-calculation, timestep, and new example notebook comparing ADV, and D3D river transect data (168, 190, 199)
- Wec_Sim support for v5.0 and cable class (185)
- Return period added for contours by mbruggs (193)
- Provide a function to convert from Te to Tp using ITTC approximation (210)
- General upkeep and compatibility maintenance (181, 211)
- General Bug Fixes (205, 208)
