@ -56,6 +56,10 @@ All notable changes to GNSS-SDR will be documented in this file.
### Improvements in Reliability:
- Fixed some potential buffer overflows.
- Avoid source code lines longer than 512 characters. This was a warning raised
by Lintian (very-long-line-length-in-source-file). Long lines in source code
could be used to obfuscate the source code and to hide stuff like backdoors or
security problems.
### Improvements in Usability:
