Hello, not sure if I'm just unable to find where it has moved to or if it was removed entirely, but prior to the most recent update there was an 'Info' button in the top menu where you could check the version of each package/module being used by the current version of Notebooks you had open. This was very helpful in troubleshooting.
Does anyone know where it can be found, now? Or if it was removed, please consider re-adding it?
