OpenFAST v3.4.0
Release Notes
OpenFAST v3.4.0 includes several major new features and bug fixes. New features include a new curled-wake model in FAST.Farm (#931), buoyancy calculations in AeroDyn 15 for MHK turbines (#957), rotor and tail furling (#1277), and new library interfaces for AeroDyn 15 and MoorDyn to couple with other codes (#1110 & #848). One major bug fix is changing the CFD coupling to use only the AeroDyn 15 mesh information -- this had led to some discrepancies in CFD results (#1324).
The full set of changes included in this version are further documented in the following listed pull requests.

Precompiled Binaries
The binary files in this release were built with the Visual Studio solution files distributed with OpenFAST (not using cmake), using
- Intel Fortran compiler 2021 (Update 2,
w_oneAPI_2021.2.0.243) with Microsoft Visual Studio Community 2019 - Microsoft Visual C++ 2019 (C), for build in Matlab
- MATLAB Version: 9.9.0.1857802 (R2020b) Update 7
- FAST.Farm_x64_OMP.exe is built with OpenMP libraries and linked with dynamic libraries.
- You will need this Intel Fortran redistributable package installed to run FAST.Farm_x64_OMP.exe if you do not already have Intel Fortran OneAPI 2021 installed. See the installation instructions here.
- You may also need a redistributable library for Visual Studio installed. See instructions here.
The other OpenFAST executables DO NOT require these redistributable libraries to be installed. Instead, they were built with static libraries.
