@@ -5,6 +5,8 @@ Enhancements:
 - Quartz64/Star64/VisionFive 2 | The extended attribute handler for ext4 security labels "CONFIG_EXT4_FS_SECURITY" has been enabled for these SBCs, required for some Docker containers. Many thanks to @gxsw for reporting this missing feature: https://github.com/MichaIng/DietPi/issues/7102
 - Quartz64/Star64/VisionFive 2 | eBPF functionality for firewall and network monitoring software like Cilium has been added to our kernel builds for these SBCs. Many thanks to @kbrighton for reporting these missing features: https://github.com/MichaIng/DietPi/issues/6834
 - Orange Pi 5 | Older U-Boot builds caused the Ethernet MAC address to be random and change on every boot. Recent U-Boot builds solve this, but they are not flashed automatically on package upgrades. We hence inform users and offer to flash the latest U-Boot image during the DietPi update. Many thanks to @thuehlinger for reporting and testing the case: https://github.com/MichaIng/DietPi/issues/6663
+- DietPi-Config | Legacy Odroid C2 resolution and GPU memory options have been removed.

 Bug fixes:
 - Network | Resolved a rare issue, where shutdowns could hang, when networking.service and [email protected] instances try to bring down the same network interface concurrently. Many thanks to @ioctl2 for reporting this issue: https://github.com/MichaIng/DietPi/issues/7104
