 ## `vm_limits_cpu_pin_strategy`
 
 Adds a new {config:option}`instance-resource-limits:limits.cpu.pin_strategy` configuration option for virtual machines. This option controls the CPU pinning strategy. When set to `none`, CPU auto pinning is disabled. When set to `auto`, CPU auto pinning is enabled.

+## `gpu_cdi`
+
+Adds support for using the Container Device Interface (CDI) specification to configure GPU passthrough in LXD containers. The `id` field of GPU devices now accepts CDI identifiers (for example, `{VENDOR_DOMAIN_NAME}/gpu=gpu{INDEX}`) for containers, in addition to DRM card IDs. This enables GPU passthrough for devices that don't use PCI addressing (like NVIDIA Tegra iGPUs) and provides a more flexible way to identify and configure GPU devices.
