nix profile history - show all versions of a profile

nix profile history [option…]

Show the changes between each version of your default profile:
# nix profile history
Version 508 (2020-04-10):
flake:nixpkgs#legacyPackages.x86_64-linux.awscli: ∅ -> 1.17.13
Version 509 (2020-05-16) <- 508:
flake:nixpkgs#legacyPackages.x86_64-linux.awscli: 1.17.13 -> 1.18.211

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 <./>.

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