Has EPSG changed again something with the Web Mercator projection? 
The EPSG report about EPSG:3857 shows that it is using a flattened 
WGS84 ellipsoid.


Compare with 


I thought that 3857 was just the same as EPSG:3785 used to be and the same than
the fake EPSG:900913. What should I believe now? Is there any valid EPSG code
for a spherical world or is it better to go with the self made EPSG:900913?
