 ### Improvements in Interoperability:
 
-- Fix setting of the signal source gain if the AGC is enabled when using the
+- Fixed setting of the signal source gain if the AGC is enabled when using the
   AD9361 front-end.
+- Fixed the regeneration of Galileo ephemeris from the reduced clock and
+  ephemeris data (CED) defined in the Galileo E1B INAV message introduced in
+  Galileo OS SIS ICD Issue 2.0.
 
 ### Improvements in Maintainability:
 
 - Rewritten Viterbi decoder for Galileo navigation messages: encapsulated in a
   class instead of being implemented as free inline functions. This improves
   memory management.
-- Update GSL implementation to v0.39.0. See
+- Updated GSL implementation to v0.39.0. See
