 I've been testing 1.4 on some  production apps for the past couple of days
 and ran into one breaking change.

 Since our ST_Extent now returns a box3d_extent, this broke one of my
 custom functions that was expecting a box2d

 To fix, I had to make a change to my app to accept box3d instead of box2d
 in the function call, but I also had to put in an auto cast

 CREATE CAST (box3d_extent AS box3d)
   WITH FUNCTION st_box3d_extent(box3d_extent)
   AS IMPLICIT;


 While this is not a bug, it is something that is likely to break some
 applications.  So I presume we should make note of it in the release
 notes.
