+### Deprecated: `level`, `message`, `line`, and `sourceId` arguments in `console-message` event on `WebContents`
+
+The `console-message` event on `WebContents` has been updated to provide details on the `Event`
+argument.
+
+```js
+// Deprecated
+webContents.on('console-message', (event, level, message, line, sourceId) => {})
+
+// Replace with:
+webContents.on('console-message', ({ level, message, lineNumber, sourceId, frame }) => {})
+```
+
+Additionally, `level` is now a string with possible values of `info`, `warning`, `error`, and `debug`.
