  The <ph name="CUSTOM_STATE_DEPRECATED_SYNTAX">:--foo</ph> syntax for the CSS custom state feature is being changed to <ph name="CUSTOM_STATE_NEW_SYNTAX">:state(foo)</ph> in <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph> in order to comply with changes that have been made in <ph name="FIREFOX_PRODUCT_NAME">Firefox</ph> and <ph name="SAFARI_PRODUCT_NAME">Safari</ph>.
