- USB devices (Wi-Fi dongle, Bluetooth dongle, 3G/4G dongle, USB DAC/speaker, and DTV dongle) are no longer supported. If your Synology NAS is currently connected via a wireless dongle, it will be disconnected after the update.
- DSM 7.0 will end support for ext3. We strongly suggest backing up the data stored on your ext3 volumes and transferring the data to volumes with supported file systems before the update.
- DSM 7.0 by default disables NTLMv1 and enables NTMLv2 only, so SMB clients (e.g., Windows XP devices, media players, network printers, smart TVs, and IP cameras) won’t be able to access your Synology NAS. To restore the connection after the update, go to Control Panel > File Services > SMB > Advanced Settings > Others and enable NTLMv1 authentication.
