2.47 5 April 2024

Added support for GNSS receiver firmware version 20230830
Improved tolerance to heading drift due to high ionospheric activity
Limitation: reports higher than expected position standard deviation when using GNSS receiver FW v20230830
2.30 10 November 2023 GNSS receiver configuration is also reset to default upon a factory restore.
More reliable RTCM input buffering in edge cases
Populate GGA number of satellites field correctly when NTRIP client sends position to NTRIP server

Fixed memory leak that could cause crash after 100's of network dataport connect/disconnect cycles
Fixed memory leak in NTRIP client
In the NTRIP client, don't prepend HTTP preamble when sending GGA message
Correctly populate the NTRIP client GGA message DOP field
