4. Fixed the issue where the USB Copy auto-mount function did not take effect.
5. Fixed the issue where the status display might be abnormal during VPN connection.

Warning:
1. If the first update prompts a decompression failure, please click update again.
2. To reduce interruptions caused by system notifications, we have readjusted the triggering rules for notifications at various levels and simultaneously modified the default system notification settings. After the update, you will need to reconfigure your personal notification preferences.
3. Due to the kernel architecture upgrade in TOS 7, the VirtualBox application will no longer be compatible with subsequent versions and will be removed from the App Center.
We recommend that users who still rely on this feature migrate their existing virtual machines to the officially supported VMs (Virtual Machines) application to ensure continued functionality.
For migration instructions, please refer to the technical documentation: https://toshelp.terra-master.com/faq/category/vms

Note: Still seeing instances of error(s) "Failed to retrieve data" (or something like that) flash across the screen after

'dmesg' continues to report multiple instances of I don't know if this is a cause.
A separate reboot post-update also shows error on GUI refresh (-221 checked so far)
Edit:
F2-425+ "Failed to retrieve data" error also appears after installing backup applications 'TFM' & 'USB Copy'

Hello TM after every update the SSH id is changed and my SSH software complain about that? I reported earlier some issues with the SSH identity, could you take another look into this behavior?

Update applied to all. The F4-424 Pro was the easiest update in a long time.
Filesystem Snapshot now purges the oldest if retention period has been reached and a new snapshot is created.
Also, I noticed this, well actually it was on v448: TNAS System Notification from Forge (The emails generated now include the device name)
Other testing will proceed during the day here.
