Upgrading Whonix 9.4 -> 9.6

Hi,
I enabled Whonix repositories by doing “sudo whonix_repository”.
After doing “sudo apt-get update && sudo apt-get dist-upgrade” in “whonixcheck” I still see 9.4 version.

[INFO] [whonixcheck] Whonix News Download Result: There is no news file available for Whonix Build Version 9.4 yet.

Do I have to import new Vbox images of Whonix 9.6?

This is expected. Build version always stays as is. Because it's the version of the build that you imported.

No. As long as it says it's current and as long nowhere else it says it should be updated, it's fine.
