+## [0.16.0] - 2018-02-14
+### Changed
+- Interpolation makes use of OpenMP
+- Cleanup of header includes
+- fypp Fortran preprocessor is ported to fckit 0.6
+
+### Added
+- Parallel structured interpolation methods (2D,3D): linear, cubic, quasicubic
+- Interpolation for multi-level and multi-variable fields
+- atlas_Trace: Fortran API and use within OpenMP parallel regions
+- StructuredColumns halo-exchange for vector fields
+- Field::halo_exchange() function
+
+### Fixed
+- Fortran compilation with PGI 18.10
+- Access to Field view within OpenMP parallel region
+- FunctionSpaces use only required halo, even if larger halo is available in mesh
+- Fixed faulty name of a Field when created through Fortran API, wrapping existing memory
+- Fix NodeColumns functionspace when mesh is created from projected grid.
+- Parallel interpolation from regular lonlat grid.
+- Spectral spherical harmonics transforms for large cases
