 * **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
 * **Removed:** An API or feature was removed, and is no longer supported by Electron.

+### Removed: `desktopCapturer.getSources` in the renderer
+
+The `desktopCapturer.getSources` API is now only available in the main process.
+This has been changed in order to improve the default security of Electron
+apps.
+
+If you need this functionality, it can be replaced as follows:
+
+```js
+// Main process
+const { ipcMain, desktopCapturer } = require('electron')
+
+ipcMain.handle(
+  'DESKTOP_CAPTURER_GET_SOURCES',
+  (event, opts) => desktopCapturer.getSources(opts)
+)
+```
+
+```js
+// Renderer process
+const { ipcRenderer } = require('electron')
+
+const desktopCapturer = {
+  getSources: (opts) => ipcRenderer.invoke('DESKTOP_CAPTURER_GET_SOURCES', opts)
+}
+```
+
+However, you should consider further restricting the information returned to
+the renderer; for instance, displaying a source selector to the user and only
+returning the selected source.
