There are two new ellipsoid definitions in this maintenance release: GSK-2011 and PZ-90.11.

To create custom datums using these new ellipsoid definitions, see the following references for the valid datum parameters:
Using one of these ellipsoids in a TAB, MIF, or WOR (workspace) file upgrades the file to version 1501.
MapInfo Pro 15.2.x and 16.0 cannot correctly use tables containing these new ellipsoid definitions. When you open such a table in MapInfo Pro 15.2.x or 16.0, the CoordSys of the table is set to WGS84. Opening a workspace in 15.2.x or 16.0 that uses the Set Map CoordSys statement with one of these ellipsoids definitions generates an error. When you dismiss the error, MapInfo Pro use WGS84 for table's CoordSys. The same error displays from an MBX or MapBasic window and when importing a MIF file that uses one of these new ellipsoids in a Coordsys clause.
