•The deprecated Orbit Determination system will not be available in versions of FreeFlyer 6.10 and higher. For the information on the new system available since FreeFlyer 6.6, see the Orbit Determination Guide.

•Microsoft Windows XP, Service Pack 3 (SP3) is a minimum system requirement for versions of FreeFlyer 6.9 and higher

•Various Objects, Properties, Methods, and Functions have been deprecated

oDeprecated Objects, Properties, Methods, and Functions are elements of FreeFlyer which are no longer recommended for use. The description of each deprecated element indicates the new recommended way to achieve the functionality of that element. The complete list of affected elements is given on the Deprecated Objects, Properties, Methods, and Functions page.

•With the additional OrbitNumber properties to improve the orbit number calculation of the Spacecraft Object, the deprecated property ScOrbitNumber was updated to be initialized as 1 in both the Spacecraft GUI and if the Spacecraft object is initialized in FreeForm Script

•With the Report command, the carriage return expression "\n" will only be evaluated as a carriage return if the special @ character is used to scan the string for escape sequences. See the Scanning Literal Strings section of the Parsing Arbitrary String Data page for more information.

•The Spacecraft.EVector property generates a vector with respect to the Spacecraft central body. In previous versions, this property was always referenced to the Earth.

•The Spacecraft.GHA (Greenwich Hour Angle) property is now calculated with respect to the MJ2000 x-axis. In previous versions, this property was erroneously calculated with respect to the TOD x-axis.
 

•With the addition of 64-bit FreeFlyer, it can now only interface with MATLAB version 7.3 or higher.
