These codecs are widespread on end devices such as smartphones, tablets, computers, and smart TVs. If the end device does not support the required codecs, the use of media files may be limited. Refer to this article for workarounds.
In addition, please note the following exceptions:
- Surveillance Station on DSM will continue to support server-side processing of AVC (H.264) streams, see the release notes.
- Deep Video Analytics (DVA) series models and VisualStation clients will retain support for AVC (H.264) and HEVC (H.265) codecs.
- To ensure package compatibility, Advanced Media Extensions (AME), File Station, Media Server, Surveillance Station, Synology Drive, Universal Search, Synology Photos and Snapshot Replication will automatically update to the latest version.

Log Center now includes disk logs.
Provided an option to change stripe cache size when the RAID type of Storage pool is RAID 5, RAID 6, RAID F1, or SHR (three disks or above).
High Availability Manager 2.0
High Availability Manager has been modularized into a package to ensure better system maintenance and offers greater update flexibility.
New mechanism can now eliminate unnecessary system reboot during major update to keep your cluster secure and maintain high service availability.

DSM
- 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.
- 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.
- Creating SSD caches on block-level LUNs is no longer supported. Existing SSD caches for block LUNs will function normally after the update.
- NT4 domains are no longer supported. Current NT4 domains will be unavailable after the update.
- 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.
- iSCSI Manager will become SAN Manager on DSM 7.0. Please refer to package release notes for more details.
- 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.
- 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.
- EZ-Internet is merged with Router Configuration in Control Panel. To set up port forwarding, go to Control Panel > External Access > Router Configuration.
- 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.
- 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 - 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 Privacy Statement for more details.

Known Issues & Limitations
- For locally modified files in a read-only sync folder, the status will always be "syncing" in DS cloud.
- Re-enabling indexing services previously set will be required when you upgrading DSM 6.0.
- Upgrade to DSM 6.0 will trigger media indexing for Audio Station browsing enhancement.
- Because of structure change, some notifications that occurred before the upgrade could abnormally displayed. All notifications generated after upgrading to DSM 6.0 will be shown normally.
- MailPlus and MailPlus Server:
- Initial retrieval of mail using the POP3 fetch function may take longer than usual.
- MailPlus Server is required to be configured before running MailPlus.
- MailPlus is required to be installed on both Synology NAS devices to ensure stability when switching load balancing services from one server to the other for MailPlus Server.
- Both Synology NAS devices must have identical MailPlus application portal and privilege settings to ensure stability when switching load balancing services from one server to the other for MailPlus Server.
- To upgrade the MailPlus Server in active-active mode from Beta 1/Beta 2 version to the official version, it is required to remove the cluster mechanism first and upgrade two nodes separately. After the upgrade, set up the active-active cluster with two nodes again and the data will be synced automatically. Such initiative will not be required after DSM 6.0.
- The function to customize library visibility will not be applied to DS video in the following mobile platforms: iOS, Windows Phone, Roku TV, and Samsung TV.
- After converting the permission type to ACL, the settings in Photo Station and File Station may still be inconsistent. For better user experience, the shared folder "photo" will be converted automatically back to Linux mode if you have done the ACL conversion in DSM 6.0 RC.
