In this release: Dependencies updates: Thrust v2.2.0 CUB v2.2.0 Eigen 3.4.0 Boost.Math 1.83.0 (NEW) Dependencies functions and classes are now available under corresponding subnamespaces. For example: hydra::thrust, hydra::boost::math and hydra::Eigen; New spline algorithms for interpolation up to four dimensions: Free functions: ```cpp hydra::spline hydra::spline2D hydra::spline4D hydra::spline3D ``` Including overloads for range-based contained and histograms with corresponding dimension. Header: hydra/Spline.h New method Interpolate(...) for dense and sparse histograms up to four dimensions. New functors: hydra::SplineFunctor hydra::Spline2DFunctor hydra::Spline4DFunctor hydra::Spline3DFunctor Defined in the headers: hydra/functions/SplineFunctor.h , hydra/functions/Spline2DFunctor.h hydra/functions/Spline3DFunctor.h hydra/functions/Spline4DFunctor.h.
