I think that the hash is indeed that if a commit. And I thought someone had written a script to find the commit from the hash. Alternatively you could look at the various system attributes the Squeak vm uses to identify itself. I *think* the Pharo vm has the same info baked in. In particular there should be the date of the commit.

This filename of the VM download url...

includes a hash "276a5ff" that I presumed identified the opensmalltalk-vm

commit from which this VM was built. i.e. so I could check that out if I wanted to compile a debug version of that VM.

However...

$ git checkout 276a5ff

says... error: pathspec '276a5ff' did not match any file(s) known to git.

so what exactly is that hash 276a5ff in the filename?
