   only the Iris coordinate system has changed.

+* `@pp-mo <https://github.com/pp-mo>`_ fixed a problem where cubes were loading from GRIB 1 with a changed coordinate
+  system, since eccodes versions >= 1.19.  This resulted from a change to eccodes, which now returns a different
+  'shapeOfTheEarth' parameter : see `eccodes issue ECC-811 <https://jira.ecmwf.int/browse/ECC-811>`_ .  This resulted
+  in a coordinate system with a different earth radius.
+  For backwards compatibilty, the earth radius has now been fixed to the same value as previously.
+  However, pending further investigation, this value may be technically incorrect and we may
+  yet decide to change it in a future release.
