Name
     nix profile history - show all versions of a profile

Synopsis
     nix profile history [option...]

Examples
     *	Show the changes between each version of your default profile:

     # nix profile history

     Version 509 (2020-05-16) <- 508:
     flake:nixpkgs#legacyPackages.x86_64-linux.awscli: 1.17.13 -> 1.18.211

Description
     This  command  shows  what packages were added, removed or upgraded between
     subsequent versions of a profile. It only shows top-level packages, not de-
     pendencies; for that, use nix profile diff-closures.

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