 This is a tutorial on how to use the Julia package [CubicHermiteSpline.jl](https://github.com/liuyxpp/CubicHermiteSpline.jl), which performs a [cubic Hermite spline interpolation](https://en.wikipedia.org/wiki/Cubic_Hermite_spline) on an array of data points, $(x_i, y_i)$, given that their associated gradients, $k_i=(dy/dx)_i$, are known in advance.
 
-New: v0.2.2 can now compute the 1st order derivative of the interpolated function.
+New

+- v0.3.0 can now perform bivariate cubic Hermite spline interpolation for 2D data points (regular and irregular grids are both supported).
+- v0.2.2 can now compute the 1st order derivative of the interpolated function.
