### Improvements in Availability
- Fixed bug that caused a random deadlock in the Observables block, preventing the computation of PVT fixes.
- Fixed bug in Galileo INAV message decoding when PLL is locked at 180 degrees, which prevented from correct navigation message decoding in some situations.
### Improvements in Efficiency
@ -42,6 +43,7 @@
- The receiver now admits FPGA off-loading, allowing for real time operation at high sampling rates and higher number of signals and channels.
- Fixed program termination (avoiding hangs and segfaults in some platforms/configurations).
- CMake now generates a summary of enabled/disabled features. This info is also stored in a file called features.log in the building directory.
- New parameter PVT.show_local_time_zone displays time in the local time zone. Subject to the proper system configuration of the machine running the software receiver.
- Improved information provided to the user in case of failure.
