What issue are you seeing?

Running "codex update" successfully updates codex, but also leaves all releases in place. This means that on every update the local ".codex" folder gets ~250M bigger. There should at least be an option to select a different behavior, or perhaps the script could keep a fixed number of older versions in place?
