Homebrew warning: deprecated verified parameter in Supercmd cask #663

Running brew install --cask supercmdlabs/supercmd/supercmd produces:

Warning: Calling the verified parameter in the url stanza is deprecated!
Use the default URL verification behaviour instead.

/opt/homebrew/Library/Taps/supercmdlabs/homebrew-supercmd/Casks/supercmd.rb:8

Homebrew says Supercmd is already installed. The install is not failing;
this is a deprecation warning from the tap's cask definition.
