 ## [Unreleased](https://github.com/gnss-sdr/gnss-sdr/tree/next)
 
+### Improvements in Efficiency:
+
+- Improved implementation of the Viterbi decoder for Galileo navigation messages.
+
+
+### Improvements in Flexibility:
+
+- New Tracking parameters allow the configuration of the C/N0 and lock detector smoothers, as well as the activation of the FLL in pull-in and steady state stages.
+- New PVT parameter enable_rx_clock_correction parameter allows to enable or disable the application of the Time solution correction to the computation of Observables.
+
+
 ### Improvements in Maintainability:
 
 - New CMake option ENABLE_ARMA_NO_DEBUG defines the macro ARMA_NO_DEBUG, which disables all run-time checks, such as bounds checking, in the Armadillo library. This will result in faster code. This option is disabled by default during development, but automatically set to ON if the option ENABLE_PACKAGING is set to ON.
