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

• File Station did not correctly display certain strings in Spanish.
• Users sometimes could not connect to iSCSI LUNs via VMware ESXi after updating QTS to 5.0.0.
• If users accessed QTS via an Smart URL and created share links in File Station, other users would not be able to access these share links.
• Recycle Bin could not delete files even after the file retention time specified by users.
• System Event Log would still display an error message even when users successfully restored system settings in Control Panel.
• The domain machine account passwords in SMB could not be automatically updated.
• If users selected a custom wallpaper and then updated the firmware, QTS desktop would revert to the default wallpaper after the update.
• RADIUS server would not use a QNAP certificate for Wi-Fi authentication after firmware update to QTS 5.0.0.
• The root directory on the TS-x53 models was smaller than normal.
• Control Panel could not display correct system temperatures and fan speeds on the TS-863U, TS-963X, and TVS-863 models.
• The TS-453B cannot play sound when users connect the NAS to a monitor via HDMI port 2 and test audio output in HD Station.
• The memory usage of dnsmasq would keep increasing when users ran the "nslookup" command in Ubuntu.

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.
• After updating QTS to 5.0.0.1808, users cannot connect to iSCSI LUNs via VMware ESXi 6.7 if they restart the ESXi server.
• 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
