  Update all packages to the latest version, with a caret.
  Only update if the update is substantial:

      update-dependency --minimal --regex '.*' ^latest

  Print the log of the above without actually making any changes.

  update-dependency --dry-run --minimal --regex '.*' ^latest

  Update all packages starting with '@jupyterlab/' to the version
  the 'latest' tag currently points to, with a caret range:

      update-dependency --regex '^@jupyterlab/' ^latest

  Update all packages starting with '@jupyterlab/' in all lerna
  workspaces and the root package.json to whatever version the 'next'
  tag for each package currently points to (with a caret tag).
  Update the version range only if the change is substantial.

      update-dependency --lerna --regex --minimal '^@jupyterlab/' ^next
`);
