This patch turns the Blur node options to inputs. Size is now a 2D vector and replaces the Size X and Y option. Bokeh was renamed to Separable to reflect its actual function. Relative was removed in favor of the newly added Relative To Pixel node workflow. There is a slight difference in variable size blurring due to float vs integer computations, so two tests were updated. Reference #137223.
