Security Updates

• Applied multiple security updates to further enhance system security.

Enhancement

Network & Virtual Switch

• Improved the DHCP server creation and editing process. When creating a DHCP server, you can also set reserved IP addresses. It is now also possible to create a DHCP server when the adapter is using a DHCP IP address, although we still strongly recommend using a static IP address.
• You can now directly set the DHCP IP address of a client device as a reserved IP address.
• Adapter connection statuses are now displayed in "Network > Interfaces > Thunderbolt".

Storage & Snapshot

• Updated Western Digital Device Analytics (WDDA) to version 8.70.5 for improved stability.

Fixed Issues

• Resolved an unusual issue where some users experienced RAID group and shared folder errors after a firmware update.
• Fixed an issue where ARM-based NAS models could not join a Windows Server 2025 domain.
• Fixed an issue where some users could not successfully stop Hyper Data Protector in App Center.
• Resolved a rare issue in the kernel-mode SMB daemon that caused the NAS to stop responding for some users.
• Fixed an issue where some Snapshot Replica files could not be restored and no log messages would be recorded about them.
• Resolved an issue where some users could not restore files from a remote snapshot vault to a local shared folder.
• Fixed a log message that displayed the wrong operating system.
• Addressed a UI issue in the App Center settings window when the display language was set to French.
• Fixed an unusual issue where a storage pool could not be recovered after a NAS restart due to a RAM error.
• Resolved a rare issue where under certain conditions some users could not recover a storage pool after replacing a disk.
• Fixed an issue where users could not successfully create a SnapSync job using existing LUNs.
• Fixed an issue in Control Panel where right-clicking an empty area would open a context menu with the "Create Shortcut" action.
• Improved WebDAV transfer speeds.
• Improved the login authentication mechanism on certain NAS models.
• Fixed a rare issue where the NAS would stop responding after the user tried to delete a user account.
• Fixed an issue where even though the QDA-A2AR adapter was already running the latest firmware, the system would still notify users that there was a newer firmware version available.
• Fixed an issue where after restarting the NAS, the system would incorrectly indicate that port trunking groups were degraded.
• Resolved an issue where using HBS 3 to back up many small files from QTS to QuTS hero might end up occupying more storage space at the destination than the original total size of the files.
• Optimized the system's storage efficiency.
