 # Release Overview
 ------
-This release includes many architectural changes and physics improvements from the OpenFAST 3.5 series.  Improvements and new features include large platform yaw dynamics, reduced order structural and aero modules, fluid-structure coupling with _AMR-Wind_, wake-added turbulence for _FAST.Farm_, linearization for MHK turbines, aeromap calculations, an updated Python library for _OpenFAST_ file handling, revised wind and wave data handling, removal of _AeroDyn14_, several new modules, and many bug fixes.  The number of changes to input files is very large, so we recommend reviewing the changelog below and notes in https://openfast.readthedocs.io/en/main/source/user/api_change.html for specifics about which files have changes.

 ### HydroDyn
-The _HydroDyn_ module was completely restructured with wave dynamics split out into a new module, _SeaState_ (documented below).  _HydroDyn_ now accesses wave-field data through a pointer to the data held in the _SeaState_ module.  Other improvements include large yaw angle dynamics, bug fixes, and feature enhancements.

Other improvements include large yaw angle dynamics, wave loads at the displaced position in surge/sway, MacCamy-Fuchs diffraction for strip-theory members, wave stretching (various models) with load smoothing, constrained New Wave theory, new strip-theory hydrostatic solution valid for near-horizontal members at the free surface, and bug fixes.
