Installing onto test bed units currently; will post if any issues appear in the coming days.

When will a .ins image become available for clean installs & the initboot that's being issued privately for TOS 7, will that become a public build in the coming weeks/months?

Trying to strategize future unit deployment processes & would like a clearer timeline regarding those two aspects.

3. Fixed an issue where system log time was one hour earlier than daylight saving time.

This is now correct in the system log (hurray) but still wrong in Media index last run.

F4-424 Pro(BIOS MADN0101.V05): update ok
F4-425 Plus(BIOS MTWL0101.V05): update ok
F5-422(BIOS MAPL0304V22): update ok

That's what I'd like to know as well

Hi. As with upgrading to TOS 7, there are a few things to keep in mind when installing TOS 7 by flashing a new USB boot drive.
The new USB boot image specifically for TOS 7 can now be downloaded here:

Sorry, the previous link was wrong. It's been corrected now.

Updated F2-221, F5-221, F2-424, F2-425Plus. And Tnas-PC*

Now both -424 and -425 show a LAN1 connection as well as alb-Bond on Lan1 and Lan2. While this is not a direct issue it is **** annoying.
The Good News: New Version of Tnas-PC no longer shows the errant LAN1 connection in it's listing. Plus WOL now appears to work on alb-Bond connections.

*Is 'Surrogate Com' a part of Tnas-PC? My windows 11 system always has issues with it while updating Tnas-PC. If I opt to try and close, it fails. If I opt to ignore it, it appears to update - but that does not feel "good". I have taken to deleting Tnas-PC entirely and re-installing it. Makes me feel better about the installation, but seems totally unnecessary. The down-side is that details that should be remembered also are deleted - I don't use Terrasync options, but I am guessing that some of that info may be 'lost' as is 'Access History'.
