• A new shapely.ops.polylabel() function has been added. It computes a point suited for labeling concave polygons (#395).

• A new shapely.ops.split() function has been added. It splits a geometry by another geometry of lesser dimension: polygon by line, line by point (#293, #371).

• Support for testing with Numpy 1.4.1 has been added (#301).
