DSM

1. 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.
2. DSM 7.0.1 ends 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.
3. DSM 7.0.1 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.
4. NFSv4.1 and related advanced functions (multipathing) are no longer supported on Synology NAS models with the following package architectures: Alpine, Alpine4k, armada38x, Avoton, Braswell, Bromolow, Cedarview, Grantley, Monaco. If you had previously enabled NFSv4 and NFSv4.1, the maximum NFS protocol is set to NFSv4 by default after the update. For more information about the package architecture of your model, please refer to this article.
5. Creating SSD caches on block-level LUNs is no longer supported. Existing SSD caches for block LUNs will function normally after the update.
6. NT4 domains are no longer supported. Current NT4 domains will be unavailable after the update.
7. The URLs used by DSM when updating or running services have been modified. Please read this article and make sure that your firewall rules are configured appropriately.
8. iSCSI Manager will become SAN Manager. Please refer to package release notes for more details.
9. When you reconnect to iSCSI targets from your VMware ESXi hosts after the DSM update, the datastores on the LUNs that are mapped to the targets may not be mounted properly. This only happens to LUNs created before the update. The resolution can be found in VMware Knowledge Base.
10. To provide comprehensive TLS support and ensure compatibility, the TLS/SSL profile level in Modern compatibility will automatically change to Intermediate Compatibility after the update.
11. EZ-Internet is merged with Router Configuration in Control Panel. To set up port forwarding, go to Control Panel > External Access > Router Configuration.
12. Python3 is merged into DSM as a built-in service. The original Python3 package will be unavailable in Package Center and you can remove it manually.
13. The following DDNS providers are removed from the service provider list at Control Panel > External Access > DDNS:
    ClouDNS, DNO-O-Matic, DNSEXIT, Dynamic DO!.jp, Joker.com, RU-CENTER, TwoDNS.de, Variomedia, Zoneedit.com
14. The updated QuickConnect connection is secured with an SSL certificate, and your QuickConnect domain will be passed to Let's Encrypt for certificate application purposes. Please refer to the Services Data Collection Disclosure for more details.
