# Description

This command shows what packages were added, removed or upgraded
between subsequent versions of a profile. It only shows top-level
packages, not dependencies; for that, use [`nix profile
diff-closures`](./nix3-profile-diff-closures.md).

The addition of a package to a profile is denoted by the string `∅ ->`
*version*, whereas the removal is denoted by *version* `-> ∅`.
