Previously, the behavior was to warn users that a cask was already installed and then skip modifying the installed version. This is different to how we handled things with formulas. For them we would upgrade any already installed formulas. This just brings casks in line with what we already do with formulas. Changes: - cmd/install: Upgrade already installed casks if HOMEBREW_NO_INSTALL_UPGRADE is not set - env_config: Update wording of HOMEBREW_NO_INSTALL_UPGRADE to include casks - remove error that was only used to alert about already installed casks Note: - The upgrade command for casks defaults to --greedy when you pass named casks to the command which means that this will always default to that behavior since you must specify the name of the cask when installing.
