 New function numpy.random.choice
 ---------------------------------
-A generic sampling function has been added which will generate samples from a given array-like. The samples can be with or without replacement, and with uniform or given non-uniform probabilities.

+
+Preliminary multi-dimensional support in the polynomial package
+---------------------------------------------------------------
+
+Axis keywords have been added to the integration and differentiation
+functions and a tensor keyword was added to the evaluation functions.
+These additions allow multi-dimensional coefficient arrays to be used in
+those functions. New functions for evaluating 2-D and 3-D coefficient
+arrays on grids or sets of points were added together with 2-D and 3-D
+pseudo-Vandermonde matrices that can be used for fitting.
+
+Support for mask-based NA values in the polynomial package fits
+---------------------------------------------------------------
+
+The fitting functions recognize and remove masked data from the fit.
