Toolbox still uses a F32 image with updates-testing enabled. Normal or Bug?

I saw that there are multiple version in the registry .
OK I just found that the TAG has a confusing semantic. It repeats the Fedora release (already in the name “f32”). I was expecting “Latest” or 1, 2, 3 …

For reference: toolbox list and podman inspect gives all the info.

I have the latest version, but still it has updates-testing enabled. is it a bug?

Question is how to get an alert on registry updates ??
