Important Notes

• The following expansion card models have reached the end of product support, starting from QuTS hero h6.0.0: Mustang-200-C-8G-R10, Mustang-200-i5-1T-32G-R10, Mustang-200-i7-1T-32G-R10, Mustang-F100, Mustang-V100, QM2-2P10G1T, QM2-2S10G1T.

• To ensure system security, starting from h6.0.0 release candidate, QuTS hero no longer allows firmware downgrade.
• For the best experience and optimal system performance, we recommend updating all available applications in the App Center after updating the firmware.

Security Updates

• Applied multiple security updates to further enhance system security.

Fixed Issues

• Fixed an issue where a console message incorrectly hinted the default admin password during setup when users connected the NAS via HDMI. (The default password should be the Cloud Key instead of the MAC address.)
• Fixed an issue where Storage & Snapshots incorrectly displayed the firmware version of the TL-R6020Sep-RP SAS JBOD expansion enclosure as 0.0.0.
• Fixed an issue where Storage & Snapshots incorrectly displayed the error status icon for TL-R6020Sep-RP SAS JBOD expansion enclosure even though the device was functioning normally.
• Fixed an issue where large-capacity storage pools would go offline after users updated QuTS hero version from h5.1.14 to h6.0.0.3500.
• Fixed an issue where the "Resize Shared Folder" button would become grayed-out and unclickable after users expanded a shared folder capacity to 5 PB (upper limit).
• Fixed an issue where the progress of applying individual ACL permission changes would be occasionally stuck at 0% if the folder structure was deep and complex.
• Fixed an issue where Storage Manager would display RAID 60 as RAID 6 when adding a new RAID group.
• Fixed an issue where the "Expand Pool" wizard could allow users to exceed the upper limit of 16 disks when creating a RAID 60 group.
• Fixed an issue where the snapshots taken on the temporary takeover node would not appear in the SMB Previous Versions after an automatic failback to the original active node.
• Fixed an issue where wired 802.1X authentication would fail after a firmware update from QuTS hero h5.x.x to h6.0.0.
• Fixed an issue where encrypted shared folders still allowed unsupported characters in passwords, which would lead to unlock failures after firmware update to QuTS hero h6.0.0.
• Fixed an issue where DNS resolution would fail if the DNS server IP address was not in the list of allowed connections defined by users.
• Fixed an issue where improper API handling would cause abnormal log writing and lead to ramdisk errors.
