 Bug Fixes:
+- DietPi-Config | Resolved an issue on RPi where I2C baudrate was not applied correctly, thus selection was ineffective. Many thanks to @flashspys for reporting this issue: https://github.com/MichaIng/DietPi/issues/2966
 - DietPi-Software | Gitea: Resolved an issue where install fails on ARMv7 systems. Many thanks to @maschiw for reporting this issue: https://github.com/MichaIng/DietPi/issues/2959
 
 As always, many smaller code performance and stability improvements, visual and spelling fixes have been done, too much to list all of them here. Check out all code changes of this release on GitHub: https://github.com/MichaIng/DietPi/pull/XXXX
