-
-The `remote` module provides a simple way to do inter-process communication
-(IPC) between the renderer process (web page) and the main process.
-
-In Electron, GUI-related modules (such as `dialog`, `menu` etc.) are only
-available in the main process, not in the renderer process. In order to use them
-from the renderer process, the `ipc` module is necessary to send inter-process
-messages to the main process. With the `remote` module, you can invoke methods
-of the main process object without explicitly sending inter-process messages,
-similar to Java's [RMI][rmi]. An example of creating a browser window from a
-renderer process:
-
-```javascript
-const { BrowserWindow } = require('electron').remote
-const win = new BrowserWindow({ width: 800, height: 600 })
-win.loadURL('https://github.com')
-```
-
-**Note:** For the reverse (access the renderer process from the main process),
-you can use [webContents.executeJavaScript](web-contents.md#contentsexecutejavascriptcode-usergesture).
-
-**Note:** The remote module can be disabled for security reasons in the following contexts:
-
-* [`BrowserWindow`](browser-window.md) - by setting the `enableRemoteModule` option to `false`.
-* [`<webview>`](webview-tag.md) - by setting the `enableremotemodule` attribute to `false`.
-
-## Remote Objects
-
-Each object (including functions) returned by the `remote` module represents an
-object in the main process (we call it a remote object or remote function).
-When you invoke methods of a remote object, call a remote function, or create
-a new object with the remote constructor (function), you are actually sending
-synchronous inter-process messages.
-
-In the example above, both [`BrowserWindow`](browser-window.md) and `win` were remote objects and
-`new BrowserWindow` didn't create a `BrowserWindow` object in the renderer
-process. Instead, it created a `BrowserWindow` object in the main process and
-returned the corresponding remote object in the renderer process, namely the
-`win` object.
-
-**Note:** Only [enumerable properties][enumerable-properties] which are present
-when the remote object is first referenced are accessible via remote.
-
-**Note:** Arrays and Buffers are copied over IPC when accessed via the `remote`
-module. Modifying them in the renderer process does not modify them in the main
-process and vice versa.
-
-## Lifetime of Remote Objects
-
-Electron makes sure that as long as the remote object in the renderer process
-lives (in other words, has not been garbage collected), the corresponding object
-in the main process will not be released. When the remote object has been
-garbage collected, the corresponding object in the main process will be
-dereferenced.
-
-If the remote object is leaked in the renderer process (e.g. stored in a map but
-never freed), the corresponding object in the main process will also be leaked,
-so you should be very careful not to leak remote objects.
-
-Primary value types like strings and numbers, however, are sent by copy.
-
-## Passing callbacks to the main process
-
-Code in the main process can accept callbacks from the renderer - for instance
-the `remote` module - but you should be extremely careful when using this
-feature.
-
-First, in order to avoid deadlocks, the callbacks passed to the main process
-are called asynchronously. You should not expect the main process to
-get the return value of the passed callbacks.
-
-For instance you can't use a function from the renderer process in an
-`Array.map` called in the main process:
-
-```javascript
-// main process mapNumbers.js
-exports.withRendererCallback = (mapper) => {
-  return [1, 2, 3].map(mapper)
-}
-
-exports.withLocalCallback = () => {
-  return [1, 2, 3].map(x => x + 1)
-}
-```
-
-```javascript
-// renderer process
-const mapNumbers = require('electron').remote.require('./mapNumbers')
-const withRendererCb = mapNumbers.withRendererCallback(x => x + 1)
-const withLocalCb = mapNumbers.withLocalCallback()
-
-console.log(withRendererCb, withLocalCb)
-// [undefined, undefined, undefined], [2, 3, 4]
-```
-
-As you can see, the renderer callback's synchronous return value was not as
-expected, and didn't match the return value of an identical callback that lives
-in the main process.
-
-Second, the callbacks passed to the main process will persist until the
-main process garbage-collects them.
-
-For example, the following code seems innocent at first glance. It installs a
-callback for the `close` event on a remote object:
-
-```javascript
-require('electron').remote.getCurrentWindow().on('close', () => {
-  // window was closed...
-})
-```
-
-But remember the callback is referenced by the main process until you
-explicitly uninstall it. If you do not, each time you reload your window the
-callback will be installed again, leaking one callback for each restart.
-
-To make things worse, since the context of previously installed callbacks has
-been released, exceptions will be raised in the main process when the `close`
-event is emitted.
-
-To avoid this problem, ensure you clean up any references to renderer callbacks
-passed to the main process. This involves cleaning up event handlers, or
-ensuring the main process is explicitly told to dereference callbacks that came
-from a renderer process that is exiting.
-
-## Accessing built-in modules in the main process
-
-The built-in modules in the main process are added as getters in the `remote`
-module, so you can use them directly like the `electron` module.
-
-```javascript
-const app = require('electron').remote.app
-console.log(app)
-```
-
-## Methods
-
-The `remote` module has the following methods:
-
-### `remote.getCurrentWindow()`
-
-Returns [`BrowserWindow`](browser-window.md) - The window to which this web page
-belongs.
-
-**Note:** Do not use `removeAllListeners` on [`BrowserWindow`](browser-window.md).
-Use of this can remove all [`blur`](https://developer.mozilla.org/en-US/docs/Web/Events/blur)
-listeners, disable click events on touch bar buttons, and other unintended
-consequences.
-
-### `remote.getCurrentWebContents()`
-
-Returns [`WebContents`](web-contents.md) - The web contents of this web page.
-
-### `remote.getGlobal(name)`
-
-* `name` String
-
-Returns `any` - The global variable of `name` (e.g. `global[name]`) in the main
-process.
-
-## Properties
-
-### `remote.require`
-
-A `NodeJS.Require` function equivalent to `require(module)` in the main process.
-Modules specified by their relative path will resolve relative to the entrypoint
-of the main process.
-
-e.g.
-
-```sh
-project/
-├── main
-│   ├── foo.js
-│   └── index.js
-├── package.json
-└── renderer
-    └── index.js
-```
-
-```js
-// main process: main/index.js
-const { app } = require('electron')
-app.whenReady().then(() => { /* ... */ })
-```
-
-```js
-// some relative module: main/foo.js
-module.exports = 'bar'
-```
-
-```js
-// renderer process: renderer/index.js
-const foo = require('electron').remote.require('./foo') // bar
-```
-
-### `remote.process` _Readonly_
-
-A `NodeJS.Process` object.  The `process` object in the main process. This is the same as
-`remote.getGlobal('process')` but is cached.

 ## Planned Breaking API Changes (14.0)
 
-### API Changed: `window.(open)`

+more closely align with Chromium's process model for security, performance and maintainability.

 The optional parameter `frameName` will no longer set the title of the window. This now follows the specification described by the [native documentation](https://developer.mozilla.org/en-US/docs/Web/API/Window/open#parameters) under the corresponding parameter `windowName`.

 You will be affected by this change if you use either `webFrame.executeJavaScript` or `webFrame.executeJavaScriptInIsolatedWorld`. You will need to ensure that values returned by either of those methods are supported by the [Context Bridge API](api/context-bridge.md#parameter--error--return-type-support) as these methods use the same value passing semantics.
 
+### Default Changed: `nativeWindowOpen` defaults to `true`
+
+Prior to Electron 14, `window.open` was by default shimmed to use
+`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
+to open synchronously scriptable child windows, among other incompatibilities.
+`nativeWindowOpen` is no longer experimental, and is now the default.
+
+See the documentation for [window.open in Electron](api/window-open.md)
+for more details.
+
+### Removed: BrowserWindowConstructorOptions inheriting from parent windows
+
+Prior to Electron 14, windows opened with `window.open` would inherit
+BrowserWindow constructor options such as `transparent` and `resizable` from
+their parent window. Beginning with Electron 14, this behavior is removed, and
+windows will not inherit any BrowserWindow constructor options from their
+parents.
+
+Instead, explicitly set options for the new window with `setWindowOpenHandler`:
+
+```js
+webContents.setWindowOpenHandler((details) => {
+  return {
+    action: 'allow',
+    overrideBrowserWindowOptions: {
+      // ...
+    }
+  }
+})
+```
+
+### Removed: `additionalFeatures`
+
+The deprecated `additionalFeatures` property in the `new-window` and
+`did-create-window` events of WebContents has been removed. Since `new-window`
+uses positional arguments, the argument is still present, but will always be
+the empty array `[]`. (Though note, the `new-window` event itself is
+deprecated, and is replaced by `setWindowOpenHandler`.) Bare keys in window
+features will now present as keys with the value `true` in the options object.
+
+```js
+// Removed in Electron 14
+// Triggered by window.open('...', '', 'my-key')
+webContents.on('did-create-window', (window, details) => {
+  if (details.additionalFeatures.includes('my-key')) {
+    // ...
+  }
+})
+
+// Replace with

+  if (details.options['my-key']) {

-# Tray
-
-## Overview
-
-<!-- ✍ Update this section if you want to provide more details -->
-
-This guide will take you through the process of creating a
-[Tray](https://www.electronjs.org/docs/api/tray) icon with
-its own context menu to the system's notification area.
-
-On MacOS and Ubuntu, the Tray will be located on the top
-right corner of your screen, adjacent to your battery and wifi icons.
-On Windows, the Tray will usually be located in the bottom right corner.
-
-## Example
-
-### main.js
-
-First we must import `app`, `Tray`, `Menu`, `nativeImage` from `electron`.
-
-```js
-const { app, Tray, Menu, nativeImage } = require('electron')
-```
-
-Next we will create our Tray. To do this, we will use a
-[`NativeImage`](https://www.electronjs.org/docs/api/native-image) icon,
-which can be created through any one of these
-[methods](https://www.electronjs.org/docs/api/native-image#methods).
-Note that we wrap our Tray creation code within an
-[`app.whenReady`](https://www.electronjs.org/docs/api/app#appwhenready)
-as we will need to wait for our electron app to finish initializing.
-
-```js title='main.js'
-let tray
-
-app.whenReady().then(() => {
-  const icon = nativeImage.createFromPath('path/to/asset.png')
-  tray = new Tray(icon)
-
-  // note: your contextMenu, Tooltip and Title code will go here!
-})
-```
-
-Great! Now we can start attaching a context menu to our Tray, like so:
-
-```js
-const contextMenu = Menu.buildFromTemplate([
-  { label: 'Item1', type: 'radio' },
-  { label: 'Item2', type: 'radio' },
-  { label: 'Item3', type: 'radio', checked: true },
-  { label: 'Item4', type: 'radio' }
-])
-
-tray.setContextMenu(contextMenu)
-```
-
-The code above will create 4 separate radio-type items in the context menu.
-To read more about constructing native menus, click
-[here](https://www.electronjs.org/docs/api/menu#menubuildfromtemplatetemplate).
-
-Finally, let's give our tray a tooltip and a title.
-
-```js
-tray.setToolTip('This is my application')
-tray.setTitle('This is my title')
-```
-
-## Conclusion
-
-After you start your electron app, you should see the Tray residing
-in either the top or bottom right of your screen, depending on your
-operating system.
