I had earlier installed Superset locally from its docker image by following instructions in https://hub.docker.com/r/apache/superset.
Now I want to find what release of Superset was installed. I exported the contents of the docker image. But if I see the contents of the package.json in superset assets folder, it shows the following at the top:
"version": "0.0.dev"
The same appears in the Superset UI in the menu About. How can I find the release or version from the image content?
