This is an almost embarrassing nit to bring up... there are two different spellings of CANCELED on the same line. [Both are legit](http://grammarist.com/spelling/cancel/) but canceled (one L) is the more common American way. Someone *could* come along later and misspell STATE_INSTALL_CANCELLED as a result, but I should hope the error would be obvious and we have JS autocompletion to help anyhow.
