             description="Version 10.3 is a minor release of Orekit.
             It includes both new features and bug fixes. New features introduced
             in 10.3 are: relativistic clock correction for range, phase, and range rate
             measurements, piece wise models for empirical forces, one-way GNSS code
             and phase measurements, support for laser ranging data (both CPF and
             CRD formats), Lense-Thirring and De Sitter relativistic corrections to
             satellite acceleration, support for AGI leap second files, new interfaces
             for attitude ephemeris files, Knocke model for Earth's albedo and infrared,
             as well as several other new features. This release includes an important
             fix in DSST orbit determination allowing to used short period Jacobian
             during state transition matrix calculation. It also fixes issues in Kalman
             orbit determination and CCSDS ADM format. See the list below for a full
             description of the changes.">
