Important Notes

• For the status of QTS updates and maintenance for your NAS model, visit https://www.qnap.com/en/product/eol.php
• Removed support for USB printers.
• To ensure data security, system stability, and storage performance, the maximum number of drives for a single RAID group is now 16 (applicable to RAID 5, RAID 6, and subgroups of RAID 50 and RAID 60). Nevertheless, users can combine multiple RAID groups into a large storage pool that contains more than 16 drives, using RAID 50, RAID 60, or RAID 10 as the RAID configuration. This enhancement will only be applied to new RAID groups. All existing RAID groups and storage systems will not be affected.

Fixed Issues

• DNS features occasionally could not function normally after firmware update to QTS 5.0.0.
• The memory usage of dnsmasq would keep increasing when users ran the "nslookup" command in Ubuntu.
• File Station would display incorrect sorting results when users tried to sort files or folders by their names.
• Users could not download files from shared folders if they manually specified folder paths and enabled advanced folder permissions.
• Users could not use longer domain names when configuring reverse proxy rules.
• On the NAS models that support a maximum of 16 snapshots per volume or LUN, users could not apply snapshot settings when Smart Versioning was selected as the snapshot retention policy.
• LDAP server would lose its user list and group list after firmware update from QTS 4.5.4 to 5.0.0.
• Users could not access home folders via AFP.
• After updating QTS to 5.0.0.1808, users could not connect to iSCSI LUNs via VMware ESXi 6.7 if they restarted the ESXi server.
• The TR-004 expansion enclosure could not enter sleep mode after firmware update to QTS 5.0.0.
• Users could not join the NAS to the Active Directory domain in Windows Server 2003 after firmware update to QTS 5.0.0.
• QTS would stop responding when users created SSD cache and then unlocked an encrypted volume.
• Even though QTS no longer require an exFAT license, Storage & Snapshots would still display a hint about the exFAT license when users tried to format an external device to exFAT.
• On the TVS-472XT, users could not switch from QTS to QuTS hero after uninstalling a Thunderbolt 3 card.
• On the TS-x31P models, users could not query CPU usage or CPU temperatures via SNMP.
• Users could not successfully update firmware for the QXG-10G2SF-NXE network expansion card in Network & Virtual Switch after updating QTS to 5.0.0.

Known Issues

• Some applications cannot access the NAS when secure connection and TLS 1.3 are enabled. This is due to a known issue in the applications. We will fix this issue in upcoming app releases.
• macOS Finder takes a long time to display content in SMB shared folders when users connect the Mac to the NAS via Thunderbolt. This problem may be due to Mac device driver issues. It only occurs to Mac devices with Intel processors and macOS 11 (or later versions).
• Thunderbolt write speeds are lower than expected in QTS 5.0.0. Note: Due to Thunderbolt driver compatibility issues, if you are using macOS 11/12 devices with Intel processors, we do not recommend updating QTS to 5.0.0 for the time being.
• QTS and QuTS hero with newer kernel versions do not support ATTO Fibre Channel adapters. If you have already installed an ATTO Fibre Channel adapter on your device, we do not recommend updating the firmware to QTS 5.0.0 or QuTS hero h5.0.0 for the time being.
• QRM+ temporarily does not support the TS-x32, TS-x32U and TS-x35A models running QTS 5.0.0. We will add support for these models in upcoming releases.
• Users cannot update the firmware of the QXG-10G2T-NXE network expansion card after updating QTS to 5.0.0.
• Control Panel cannot display the information of the TPU installed in the M.2 slot on the QGD-1602P.
• After users rename a shared folder, QuLog Center still displays the original folder name in Accessed Resources.
• Network & Virtual Switch displays unexpected interface connection status and FEC status when users connect the following pairs of devices:
  • NAS with Mellanox network adapter + NAS with Mellanox network adapter

Other Changes

Control Panel

• Replaced SQL Server with MariaDB 5/MariaDB 10, which can be installed in the App Center.
• Removed iSCSI Service from Service Binding in Control Panel. Users can now configure iSCSI service binding settings in iSCSI & Fibre Channel.

Qboost

• Qboost is no longer a built-in application of QTS. Users can choose to install Qboost in App Center.

App Center

• To ensure system security, QTS now automatically disables applications that are not updated and that do not meet the minimum version requirements.
• Removed support for the following applications, utilities, or services:
  • WebERP
  • GLPI
  • Vtiger CRM
  • Ragic Cloud DB

QVR Pro Client & QVR Smart Client

• Starting from QTS 5.0.0, HybridDesk Station no longer supports QVR Pro Client (HDMI output). You can install QVR Smart Client on HybridDesk Station as the client software for your QVR Pro, QVR Elite, or QVP surveillance servers. Note that QVR AI Pack License is required for using QVR Smart Client. You can continue using QVR Pro Client on Windows or macOS as the client software for your surveillance servers to watch live views or play back recordings.
