Update Notes
Bugs fixed:

3. Fixed an issue where modifying the IP might cause TNAS.online to fail to automatically reconnect.
4. Fixed an issue where some pop-up prompts displayed empty content.
5. Fixed an issue where the firewall could not be disabled.
6. Fixed an issue where an incorrect prompt appeared when editing permissions for a shared folder that has used up its quota.
7. Fixed an issue where the USB capacity usage threshold notification could not be set properly.
8. Fixed an issue where newly authorized directories for Time Machine did not take effect immediately.
9. Fixed an issue where switching to an LDAP domain after joining an AD domain did not provide any prompt.

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. In the current version, the auto-mount function for USBCopy devices is temporarily unavailable. To ensure the normal use of this feature, please refrain from updating to this version for now and wait until the next version is released and the issue is resolved before upgrading.
4. 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.

Is the Windows client download version correct? It's 5.2.506 and I already have 5.2.510 and 5.2.520 downloaded.

In Control Panel/Media Index there is a Last Run date even though media indexing is disabled. I think it would be better if this showed the same --- as Status even if it's only a cosmetic change.

F2-425 Plus updated successfully.

Thank you for your feedback. The download link has been updated.
We have noted your suggestion regarding the display of the "Last Run Date" status in "Control Panel/Media Index" and will forward it to the product team. We will consider optimizing it after evaluation.

F2-221 updated with no apparent problems

For me -virtualBox regression. None of the machines will start. The error is as follows:

All three updated, well the F4-424 Pro needed a push, after the update reboot, the webgui showed update in progress. The HDMI console showed the SQL service didn't start and numerous messages about journald not starting. Couldn't putty in. Hard power off/on. System came up fine, no other issues. Other testing to follow tomorrow.

You can visit the online chat on our official website to inquire about installing the previous version of TOS 7, export the virtual machines, and then import them into VMs.

Just noticed on all three of my devices (I'm tired of saying NAS(s), NAS's )

After applying v448
The email notification settings for the warning and information in all categories were turned off. Is this something new or a mistake?
Before I had every category set to notify for notification and email.
