SU2 is being developed by individuals and organized teams around the world. The SU2 Lead Developers are: Dr. Francisco Palacios and Dr. Thomas D. Economon.
Major updates to the MPI implementation that improve performance and align with the MPI 3.0 standard.
Modifications that greatly enhance computational efficiency and memory scalability of mesh partitioning for parallel calculations.
New constant lift mode. Specify a target lift coefficient rather than a fixed angle of attack.
Upgrades to the CGNS mesh reader for further support of mixed-element meshes.
General bug fixes and maintenance.
Unsupported: 3.2.1
8 September 2014
Additional verification test cases for shape design using the compressible adjoint capability (in collaboration with Lockheed Martin).
Preliminary structure for the simulation of real gases (in collaboration with TuDelft and Politecnico di Milano).
New FFD design variables (in collaboration with Volkswagen).
New preconditioners and smoothers for implicit time integration (in collaboration with Intel).
Simplified configuration options (in collaboration with the large SU2 users community. Thanks!).
General bug fixes and maintenance.
Unsupported: 3.2.2

Fully parallel preprocessing with ParMETIS.
SA-neg turbulence model.
Adaptive CFL.
Easily generate FFD boxes with new options.

Scale, rotate, translate meshes in SU2_DEF.
Iterative smoothers: Jacobi, LU-SGS, ILU(0).
Updated non-dimensionalization options for ease of use.
General bug fixes.
Performance Improvements:
MPI and general performance improvements.
Increased mesh deformation stability for all unstructured mesh elements.
CGNS parallel partitioning improvements.
Automated multigrid parameter selection.
Increased robustness for upwind methods.
Low-storage output mode.
Additional Updates:
Updated documentation on the GitHub wiki, including user tutorials and new developer information.

Unsupported: 4.0.1
1 September 2015
Improved performance for scaling, rotating, translating meshes using SU2_DEF.
Configuration file option MATH_PROBLEM now requires CONTINUOUS_ADJOINT instead of ADJOINT.
New datatype abstraction for future flexibility: all current and future double types in the code should be the new su2double type.
New MPI wrapper abstraction for future flexibility.
Restructuring of the test case suite: the configuration files for the TestCases repository now live in a mirrored directory structure under the SU2 repository in order to make automatic testing with Travis CI more effective. To use, download both repositories and recursively copy the contents of one TestCases/ directory into the other to complete the set.
