@@ -34,6 +34,11 @@ All notable changes to GNSS-SDR will be documented in this file.
`TelemetryDecoder_XX.dump_crc_stats_filename=./crc_stats` in the configuration
file. At the end of the processing (or exiting with `q` + `[Enter]`), the CRC
check success rate will be reported in a file.
- The `UHD_Signal_Source` learned to dump data in folders that do not exist,
*e.g.*, if `SignalSource.dump=true`,
`SignalSource.dump_filename=./non-existing/data.dat`, and the `non-existing`
folder does not exist, it will be created if the running user has writing
permissions. This also works for absolute paths.
