## [Unreleased](https://github.com/gnss-sdr/gnss-sdr/tree/next)
### Improvements in Accuracy
- Local clock correction based on PVT solution (error kept below 1 ms).
### 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.
- Fixed bug in Galileo INAV/FNAV message decoding when PLL is locked at 180 degrees, which prevented from correct navigation message decoding in some situations.
- Fixed PVT computation continuity through the TOW rollover.

- Fix bug in GLONASS dual frequency receiver.
- Added a custom UDP/IP output for PVT data streaming.
- Improved Monitor block with UDP/IP output for internal receiver's data streaming.
- Custom output formats described with .proto files, making easier to other applications reading them in a forward and backward-compatible fashion upon future format changes.
- Custom output formats described with .proto files, making easier to other applications reading them in a forward and backward-compatible fashion upon future format changes. New dependency: Protocol Buffers >= 3.0.0
- Fixes in RINEX generation: week rollover, annotations are not repeated anymore in navigation files. Parameter rinexnav_rate_ms has been removed, annotations are made as new ephemeris arrive.
- Fixes in RTCM messages generation: week rollover.
@ -45,6 +50,7 @@
- Added interfaces for FPGA off-loading.
- CMake scripts now follow a modern approach (targets and properties) but still work with 2.8.12.
- Improvements for macOS users using Homebrew.
- The volk_gnsssdr library can now be built without requiring Boost if the compiler supports C++17.
### Improvements in Reliability
