+GSkyPixel
+  The class now supports 1D and 2D pixels. Type conversion methods
+  have been added that allow assigning integer and double precision
+  values from and to GSkyPixel for 1D pixels. A size() method has
+  been added that returns the pixel dimension. Also the is1D() and
+  is2D() methods can be used to determine whether a pixel is 1D
+  or 2D. index() methods have been added to set and get 1D pixel
+  values. A xy() method has been added to set x and y simultaneously
+  for 2D pixels. 1D and 2D pixel constructors exist now for
+  integer and double precision values.
+
+GWcs => GSkyProjection
+  The GWcs class has been renamed to GSkyProjection as it is more
+  general than the World Coordinate Systems. A size() method has
+  been added that returns the dimension of the projection (1D or
+  2D). The integer index methods have been removed as GSkyPixel
+  now supports 1D and 2D pixels.
+
+GWcslib => GWcs
+  The GWcslib class has been renamed to GWcs. The class now conforms
+  to the GSkyProjection base class interface.
+
+GWcsHPX => GHealpix
+  The GWcsHPX class has been renamed to GHealpix as the Healpix
+  projection is not a World Coordinate System. GHealpix is no

+GWcsRegistry
+  Now holds objects of renamed type GWcs (see GHealpix).
