Important Notes

• QuTS hero does not support downgrading from h5.1.x to h5.0.1 or earlier. Downgrading firmware can be risky. Please make sure you fully understand and accept the risks if you decide to downgrade your firmware.
• Apple recently fixed an issue that caused macOS computers with an M1 or M2 CPU to occasionally disconnect from Thunderbolt 4 connections. Please update your macOS to version 13.5.1 or later to ensure a stable connection with your QNAP Thunderbolt 4 devices.
• This version is released in a staged rollout, which means we initially release this version to a small portion of users and then gradually reach more users over time.

Security Updates

• Applied multiple security updates to further enhance system security.

Enhancements

Storage & Snapshots

• The extended power condition (EPC) feature of certain SATA drives is now disabled by default. This ensures that the drives' load cycle count does not increase on its own, so that the system can correctly determine when the drives should go into standby mode.

Fixed Issues

• Fixed an issue in Resource Monitor > Storage Resource > Storage Space, where under certain conditions an incorrect value would be displayed under "Other".
• Improved the stability of NTFS ADS metadata after a NAS restart.
• Fixed a Hungarian translation issue on the desktop dashboard.

• Fixed an issue in HBS 3 where after syncing a folder with Windows ACL permissions from a QTS NAS to a QuTS hero NAS, domain users could not access the destination folder even though they could access the source folder.
• Fixed an issue on NAS models with HDMI output where after connecting the NAS to an HDMI device and installing HybridDesk Station, the NAS would stop responding after a restart.
• Resolved an issue where some users experienced sudden disconnection of iSCSI service to an ESXi host.

• Resolved an issue in Storage & Snapshots where after running a disk test that resulted in a read failure, the disk health summary page occasionally did not display the correct warning description.
• Storage & Snapshots now correctly displays the disk mode for SSDs as "Active" or "Standby" (previously "Active (Spinning)" or "Standby (Spindown)").
• Resolved an issue in Storage & Snapshots where a disk's SED status was inconsistent between the "Overview" page and the "Disks/VJBOD > Disks" page.
