Display changelog upon upgrade

What variant of Codex are you using?

CLI

What feature would you like to see?

codex changes very quickly, unfortunately not all changes are benign. For example security model change that enabled codex to run commands and was only confide by sandbox caught me by surprised. Fortunately I quickly realized that codex happily runs docker commands without any confirmation which equals root on host.
To avoid similar surprises codes should print, or at least prompts to print, changelog information upon version upgrade.
