Here are the full release notes as of April 25th, 2023.

Version: 7.2-64551 Release Candidate

(2023-04-25)

Important Note

  1. After installing this update, you will not be able to downgrade to a previous DSM version.
  2. This update will restart your Synology NAS.
  3. Starting from this version, logs for drives will no longer appear in Storage Manager > HDD and will be available only in Log Center.
  4. Removed the "Automatically create port forwarding rules" option from QuickConnect advanced settings to increase network security.
  5. Users can now create a Btrfs volume of up to 1 PB on specific Synology NAS models.. This update automatically converts existing volumes that use the Btrfs (Peta Volume) file system to Btrfs. However, to create a volume larger than 200 TB, a RAID 6 storage pool and at least 64 GB of system memory are still required. Learn more

What’s New

  1. Added support for WriteOnce shared folders. This feature is based on the Write Once, Read Many (WORM) technology and can be enabled to prevent files from being modified, deleted, or renamed for a specified period.
  2. Added support for volume encryption. All volume encryption keys are stored in the Encryption Key Vault, which can be set up on a local Synology NAS or via KMIP on a remote Synology NAS.
  3. Added more Synology NAS models to support M.2 NVMe SSD storage pools. Learn more
  4. Added more Synology NAS models to support the M2D18 adapter card: RS822RP+, RS822+, RS1221RP+, and RS1221+.
  5. Added more SSD cache group management options, including changing the RAID type and replacing a drive.
  6. Added support for inline zero-block removal to increase the efficiency of data deduplication.
  7. Adjusted how drive information is presented in Storage Manager. Users can now quickly check the condition of their drives by looking at the "Drive Status" field.
  8. Users can now view the amount of used and free space for each storage pool and volume in Storage Manager.
  9. Added a warning notification for when the available shared folder quota is low.
  10. Supports deleting individual desktop notifications.
  11. Supports sending DSM notifications via additional webhook providers, including LINE and Microsoft Teams.
  12. Supports creating custom notification rules for system events, giving users greater control over what notifications to receive.
  13. Supports exporting a list of users and of groups.
  14. Added support for SAML to integrate DSM with external SSO servers.
  15. Added the option to allow non-admin users to safely eject USB devices.
  16. Users can now manually input the IP addresses or FQDNs of one or more domain controllers in the trusted domain. This allows Synology NAS to sync domain data directly with the specified domain controllers.
  17. Users can now enable Synology's email server to send DSM notifications directly to their Synology Account.

Limitation

  1. S.M.A.R.T. testing for M.2 NVMe SSDs is no longer supported.
  2. Starting from DSM 7.2 Beta, Virtual Machine Manager will no longer support creating clusters with older DSM versions. Please update each host in the cluster to the same DSM version or above versions for the Virtual Machine Manager cluster to operate properly.
  3. If your Synology Directory Server domain has been migrated from Windows AD, we recommend not updating to this version as this may cause start-up failure of your Synology Directory Server. We will fix this issue in the upcoming release.

Most of the new features we have already seen in the beta version, like WORM and volume encryption, but this version brings a huge list of security patches and updates that are a welcome sight for any user.

Testing of this version will start soon and I will post any major breaking changes or issues that I might experience.
