@@ -57,6 +57,8 @@ All notable changes to GNSS-SDR will be documented in this file.
- Now the program exits properly if a SIGINT signal is received (_e.g._, the
user pressing Ctrl+C, or another user application sending an interruption
signal).
- The estimated CN0 value is now printed in the terminal when navigation data is
succesfully decoded.
