+Version 11.2 is a minor release of Orekit.
+
+Highlights in the 11.2 release are:
+
+* the Hatch Filter for GNSS measurements smoothing
+* the parsing and writing of CCSDS CDM in both KVN and XML formats
+* the parsing of SOLFSMY and DTC data for JB2008 atmospheric model
+* the parsing of EOP in Sinex files
+* new measurements for orbit determination: TDOA, bi-static range and range rate
+* support for ITRF 2020 version
+* the computation of mean orbital parameters in the sense of Eckstein-Hechler or Brouwer-Lyddane models.
+* the J2-relativistic clock offset for GNSS measurements
+* an update of the CCSDS ODM v3 format
+* an improvement of the frame transformation
+
+This version depends on Hipparchus 2.1
