QNAP Release Note

QTS 5.2.1

QTS 5.2.1.2930 build 20241025

[Important Notes]
- If you are using an NVIDIA GPU card and have updated the firmware to QTS 5.2.1 (or their later versions), please update NVIDIA GPU Driver in the App Center.
- Due to certain compatibility issues, ARM-based NAS models are unable to run certain third-party applications in QTS 5.2.1. We recommend users of the following applications on an ARM-based NAS to wait until new versions of the applications are released before updating to QTS 5.2.1 or later:
- AhsayOBM (9.7.0.200)
- CloudBackoGo (9.7.2.0 or earlier)
- Qfinder Discovery Service uses UDP port 8097 for communication. To ensure the service functions properly, allow devices in your internal network to access port 8097 through your firewall before enabling the service. We recommend blocking external access to this port if your device permits external connections.

[Security Updates]
- Applied multiple security updates to further enhance system security.

[New Features]
System
- Starting from QTS 5.2.1, certain QTS NAS models now also support the QuTS hero operating system. After updating to QTS 5.2.1, you can switch to QuTS hero by reinitializing the NAS. Applicable NAS models: HS-264, TBS-464, TS-253E, TS-453E, TS-264, TS-364, TS-464, TS-464C2, TS-664, and TS-466C.

Control Panel
- Administrators can now edit the user ID (UID) of an administrator in Control Panel > Privilege > Users > Edit Account Profile.

Storage & Snapshots
- Storage & Snapshots now displays Qfiling-related storage information on shared folders that are configured as Qfiling space recycling folders.

[Enhancement]
SSH
- Improved SSH connectivity and added support for additional encryption algorithms such as ECDSA and ED25519. To give users more transition time, we have also temporarily reinstated support for umac-64@openssh.com and hmac-sha1; however, we highly recommend users to switch to other algorithms as soon as possible to ensure greater security.

Control Panel
- Upgraded Apache HTTP Server to version 2.4.62 for improved security.
- Improved the shared folder name sorting method in Control Panel for easier browsing.

Domain Security
- Enhanced LDAP client functionality by providing "one" and "subtree" as search scope options.

Storage & Snapshots
- Improved the write performance of the read-only cache type.
- Enhanced the "Time since last snapshot" UI design in Storage & Snapshots > Data Protection > Snapshot.

File Station
- Users can update to File Station 5 by opening App Center and clicking update on the File Station 5 app icon.
- File Station can now access your Personal Vault in myQNAPcloud Storage. Note: You will need to provide your Personal Vault's encryption key.
- File Station now displays information about Qfiling space recycling tasks for folders.
- Improved the loading time when opening video files.
(Since File Station can now be manually updated in App Center starting from QTS 5.2.1, you can read detailed release information for the application at: https://www.qnap.com/en/app_releasenotes/list.php?app_choose=FileStation5)
