The result of Ellipsoid::getName() for the built-in WGS-84 ellipsoid returned World␣Geodetic␣System␣␣1984 in phpgeo 2.x (two space characters before 1984). Starting with phpgeo 3.0, the result is World␣Geodetic␣System␣1984 (single space character before 1984). Please verify that your code is still working if you’re using that result.

Starting with phpgeo 3.0 class constant visiblity modifiers are used. One class constant was changed to private visibility: BearingSpherical::EARTH_RADIUS. Please verify that your code isn’t using that class constant.

No further breaking changes were introduced with phpgeo 3.0.
