- Only report an update available if the version number of the release is greater than the current version - Removes `command` dependency from `update` package; instead, pass current version as an argument - Remove `brew upgrade` instructions since we can't be certain that gh was installed via Homebrew in the first place. - Does not check for updates unless stderr is a tty - Preserve stderr color output even if stdout is not a tty - Fixes stderr color output on Windows
