Ich hab zwar nichts mit QuTS hero zu tun, aber weil es hier heute so furchtbar langweilig ist: Es gibt eine neue hero Version 
Neben dem im "kleinen" QTS Update gefixten Problem mit QM2 Lüftern gibt es hier noch ein paar weitere Fixes:

New Feature
Storage&Snapshots
To ensure the availability of your data, Storage & Snapshots now supports "Replace & Detach", which allows you to copy data from a faulty disk to a spare disk and then safely detach the faulty disk.
Security Updates
Fixed the security issue CVE-2022-27600.
Applied multiple security updates to further enhance system security.
Fixed Issues
Fixed an issue where QuTS Hero might sometimes report abnormal fan speeds on the QM2 expansion card.
Fixed an issue where users could not unlock an encrypted folder in File Station and the system might display an error message after a failed attempt.
Fixed an issue where installing certain applications might occasionally cause Storage & Snapshots to keep refreshing shared folder statuses.
Fixed an issue where users could not close the Quick Start wizard in Network & Virtual Switch if there had been another user whose username only differed in case sensitivity.
Fixed an issue where security logs might repeatedly record the same events.
Fixed an issue where File Station would display a preview window instead of directly downloading files when users tried to download files via a share link.
Fixed an issue where the system generated dnsmasq logs whenever QVPN was connected or disconnected, causing insufficient space on the ram disk.
Fixed an issue where the system could not mount a RDX QuikStor external drive that was formatted in ext4 and set to write-protection mode.
Fixed an issue where the system would create a duplicate snapshot schedule if users clicked the "Apply" button twice when editing a snapshot schedule.
Fixed an issue where users could not back up data for an exFAT external drive with HBS.
Fixed an issue where the Overview section in Storage & Snapshots could not correctly display the status of SED drives.
Fixed an issue where after entering the auto-protection mode, the NAS could not restart when the UPS resumed power. (Note: If a UPS is set up, the NAS can enter the auto-protection mode in the event of a power outage. Normally, the NAS will restart when the UPS resumes power.)
Resolved an issue where the system could not send SNMP traps via a specified IP address after users created a VLAN connection.
Fixed an issue where the NAS might occasionally shut down unexpectedly after users updated Container Station to 3.0.
Known Issues
Users sometimes cannot switch between different FEC (Forward Error Correction) modes for the QXG-25G2SF-CX6LX network expansion card.
SnapSync jobs for LUNs may fail after users edit LUN names.
After users edit LUN settings and run a Snapshot Replica job, the destination NAS cannot correctly display LUN information in Snapshot Vault.
Storage & Snapshots and iSCSI & Fibre Channel sometimes display different sizes of the same LUN after users revert a LUN by importing a snapshot.
