**3DS firmware 11.16.0 was recently released**. 以下是你該知道的:
- If your device is running *Luma 11.0*, it is *100% safe* to update. You can check your Luma version by holding (Select) while booting your device.
- If your device is on an older Luma version, you should [update Luma](checking-for-cfw) before you update your device to 11.16.0.
- If your device does not yet have custom firmware, you can still install it on this version for free without any additional hardware, but the recommended method has been changed.
* If you are using Windows to move files to/from the SD card, you may want to [enable file extensions](file-extensions-(windows)) to avoid misnaming files.
