launch lakeFS 1.3.1, browsing to the web server at 8000, it notifies a new version available, which will forward me to the Github page where I can see the latest being 1.7.0 How can I get that?

You need to pull the latest image. 1.3.1 is cached locally with tag latest. Add

--pull=always

to your run command

it's pulling, nice, thanks

--pull=newer

Pull if the image on the registry is newer than the one in the local containers storage. An image is considered to be newer when the digests are different. Comparing the time stamps is prone to errors. Pull errors are suppressed if a local image was found.
