+## Added Features
+- **HIDDEV and HIDRAW**: For full USB HID device support in WSL2.
+- **Full CGroupsV2**: Enabled with `systemd.unified_cgroup_hierarchy=1` and all required options.
+- **Kernel IO functions**: Includes `CONFIG_BLK_CGROUP_IOCOST=y`, `CONFIG_IO_WEIGHT=y`, and IO scheduling controllers with weights (`weight`), missing from Microsoft's base kernel to optimize containers and disk-intensive workloads.
