+* `disableAutoHideCursor` boolean (optional) - Whether to hide cursor when typing.
+  Default is `false`.
+* `autoHideMenuBar` boolean (optional) - Auto hide the menu bar unless the `Alt`
+  key is pressed. Default is `false`.
+* `enableLargerThanScreen` boolean (optional) _macOS_ - Enable the window to
+  be resized larger than screen. Only relevant for macOS, as other OSes
+  allow larger-than-screen windows by default. Default is `false`.
+* `backgroundColor` string (optional) - The window's background color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. Alpha in #AARRGGBB format is supported if `transparent` is set to `true`. Default is `#FFF` (white).

+* `hasShadow` boolean (optional) - Whether window should have a shadow. Default is `true`.
+* `opacity` number (optional) _macOS_ _Windows_ - Set the initial opacity of
+  the window, between 0.0 (fully transparent) and 1.0 (fully opaque). This
+  is only implemented on Windows and macOS.
+* `darkTheme` boolean (optional) - Forces using dark theme for the window, only works on
+  some GTK+3 desktop environments. Default is `false`.

+  Default is `false`. On Windows, does not work unless the window is frameless.
+* `type` string (optional) - The type of window, default is normal window. See more about
+  this below.
+* `visualEffectState` string (optional) _macOS_ - Specify how the material
+  appearance should reflect window activity state on macOS. Must be used
+  with the `vibrancy` property. Possible values are:
+  * `followWindow` - The backdrop should automatically appear active when the window is active, and inactive when it is not. This is the default.
+  * `active` - The backdrop should always appear active.
+  * `inactive` - The backdrop should always appear inactive.
+* `titleBarStyle` string (optional) _macOS_ _Windows_ - The style of window title bar.
+  Default is `default`. Possible values are:
+  * `default` - Results in the standard title bar for macOS or Windows respectively.
+  * `hidden` - Results in a hidden title bar and a full size content window. On macOS, the window still has the standard window controls (“traffic lights”) in the top left. On Windows, when combined with `titleBarOverlay: true` it will activate the Window Controls Overlay (see `titleBarOverlay` for more information), otherwise no window controls will be shown.
+  * `hiddenInset` _macOS_ - Only on macOS, results in a hidden title bar
+    with an alternative look where the traffic light buttons are slightly
+    more inset from the window edge.
+  * `customButtonsOnHover` _macOS_ - Only on macOS, results in a hidden
+    title bar and a full size content window, the traffic light buttons will
+    display when being hovered over in the top left of the window.
+    **Note:** This option is currently experimental.
+* `trafficLightPosition` [Point](point.md) (optional) _macOS_ -
+  Set a custom position for the traffic light buttons in frameless windows.
+* `roundedCorners` boolean (optional) _macOS_ - Whether frameless window
+  should have rounded corners on macOS. Default is `true`. Setting this property
+  to `false` will prevent the window from being fullscreenable.
+* `thickFrame` boolean (optional) - Use `WS_THICKFRAME` style for frameless windows on
+  Windows, which adds standard window frame. Setting it to `false` will remove
+  window shadow and window animations. Default is `true`.
+* `vibrancy` string (optional) _macOS_ - Add a type of vibrancy effect to
+  the window, only on macOS. Can be `appearance-based`, `titlebar`, `selection`,
+  `menu`, `popover`, `sidebar`, `header`, `sheet`, `window`, `hud`, `fullscreen-ui`,
+  `tooltip`, `content`, `under-window`, or `under-page`.
+* `backgroundMaterial` string (optional) _Windows_ - Set the window's
+  system-drawn background material, including behind the non-client area.
+  Can be `auto`, `none`, `mica`, `acrylic` or `tabbed`. See [win.setBackgroundMaterial](../browser-window.md#winsetbackgroundmaterialmaterial-windows) for more information.
+* `zoomToPageWidth` boolean (optional) _macOS_ - Controls the behavior on
+  macOS when option-clicking the green stoplight button on the toolbar or by
+  clicking the Window > Zoom menu item. If `true`, the window will grow to
+  the preferred width of the web page when zoomed, `false` will cause it to
+  zoom to the width of the screen. This will also affect the behavior when
+  calling `maximize()` directly. Default is `false`.
+* `tabbingIdentifier` string (optional) _macOS_ - Tab group name, allows
+  opening the window as a native tab. Windows with the same
+  tabbing identifier will be grouped together. This also adds a native new
+  tab button to your window's tab bar and allows your `app` and window to
+  receive the `new-window-for-tab` event.
+
+When setting minimum or maximum window size with `minWidth`/`maxWidth`/
+`minHeight`/`maxHeight`, it only constrains the users. It won't prevent you from
+passing a size that does not follow size constraints to `setBounds`/`setSize` or
+to the constructor of `BrowserWindow`.
+
+The possible values and behaviors of the `type` option are platform dependent.
+Possible values are:
+
+* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
+  `notification`.
+  * The `desktop` type places the window at the desktop background window level
+    (kCGDesktopWindowLevel - 1). However, note that a desktop window will not
+    receive focus, keyboard, or mouse events. You can still use globalShortcut to
+    receive input sparingly.
+  * The `dock` type creates a dock-like window behavior.
+  * The `toolbar` type creates a window with a toolbar appearance.
+  * The `splash` type behaves in a specific way. It is not
+    draggable, even if the CSS styling of the window's body contains
+    -webkit-app-region: drag. This type is commonly used for splash screens.
+  * The `notification` type creates a window that behaves like a system notification.
+* On macOS, possible types are `desktop`, `textured`, `panel`.
+  * The `textured` type adds metal gradient appearance
+    (`NSWindowStyleMaskTexturedBackground`).
+  * The `desktop` type places the window at the desktop background window level
+    (`kCGDesktopWindowLevel - 1`). Note that desktop window will not receive
+    focus, keyboard or mouse events, but you can use `globalShortcut` to receive
+    input sparingly.
+  * The `panel` type enables the window to float on top of full-screened apps
+    by adding the `NSWindowStyleMaskNonactivatingPanel` style mask,normally
+    reserved for NSPanel, at runtime. Also, the window will appear on all
+    spaces (desktops).
+* On Windows, possible type is `toolbar`.

+
+> A basic native view.
+
+Process: [Main](../glossary.md#main-process)
+
+`View` is an [EventEmitter][event-emitter].
+
+### `new View()`
+
+Creates a new `View`.
+
+### Instance Events
+
+Objects created with `new View` emit the following events:
+
+#### Event: 'bounds-changed'
+
+Emitted when the view's bounds have changed in response to being laid out. The
+new bounds can be retrieved with [`view.getBounds()`](#viewgetbounds).
+
+### Instance Methods
+
+Objects created with `new View` have the following instance methods:
+
+#### `view.addChildView(view[, index])`
+
+* `view` View - Child view to add.
+* `index` Integer (optional) - Index at which to insert the child view.
+  Defaults to adding the child at the end of the child list.
+
+#### `view.removeChildView(view)`
+
+* `view` View - Child view to remove.
+
+#### `view.setBounds(bounds)`
+
+* `bounds` [Rectangle](structures/rectangle.md) - New bounds of the View.
+
+#### `view.getBounds()`
+
+Returns [`Rectangle`](structures/rectangle.md) - The bounds of this View, relative to its parent.
+
+#### `view.setBackgroundColor(color)`
+
+* `color` string - Color in Hex, RGB, ARGB, HSL, HSLA or named CSS color format. The alpha channel is
+  optional for the hex type.
+
+Examples of valid `color` values:
+
+* Hex
+  * `#fff` (RGB)
+  * `#ffff` (ARGB)
+  * `#ffffff` (RRGGBB)
+  * `#ffffffff` (AARRGGBB)
+* RGB
+  * `rgb\(([\d]+),\s*([\d]+),\s*([\d]+)\)`
+    * e.g. `rgb(255, 255, 255)`
+* RGBA
+  * `rgba\(([\d]+),\s*([\d]+),\s*([\d]+),\s*([\d.]+)\)`
+    * e.g. `rgba(255, 255, 255, 1.0)`
+* HSL
+  * `hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)`
+    * e.g. `hsl(200, 20%, 50%)`
+* HSLA
+  * `hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)`
+    * e.g. `hsla(200, 20%, 50%, 0.5)`
+* Color name
+  * Options are listed in [SkParseColor.cpp](https://source.chromium.org/chromium/chromium/src/+/main:third_party/skia/src/utils/SkParseColor.cpp;l=11-152;drc=eea4bf52cb0d55e2a39c828b017c80a5ee054148)
+  * Similar to CSS Color Module Level 3 keywords, but case-sensitive.
+    * e.g. `blueviolet` or `red`
+
+**Note:** Hex format with alpha takes `AARRGGBB` or `ARGB`, _not_ `RRGGBBAA` or `RGB`.
+
+#### `view.setVisible(visible)`
+
+* `visible` boolean - If false, the view will be hidden from display.
+
+### Instance Properties
+
+Objects created with `new View` have the following properties:
+
+#### `view.children` _Readonly_
+
+A `View[]` property representing the child views of this view.

 * **Removed:** An API or feature was removed, and is no longer supported by Electron.
 
+## Planned Breaking API Changes (30.0)
+
+### Behavior Changed: cross-origin iframes now use Permission Policy to access features
+
+Cross-origin iframes must now specify features available to a given `iframe` via the `allow`
+attribute in order to access them.
+
+See [documentation](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#allow) for
+more information.
+
+### Removed: The `--disable-color-correct-rendering` switch
+
+This switch was never formally documented but it's removal is being noted here regardless. Chromium itself now has better support for color spaces so this flag should not be needed.
+
+## Planned Breaking API Changes (29.0)
+
+### Behavior Changed: `ipcRenderer` can no longer be sent over the `contextBridge`
+
+Attempting to send `ipcRenderer` as an object over the `contextBridge` will now result in
+an empty object on the receiving side of the bridge. This change was made to remove / mitigate
+a security footgun, you should not directly expose ipcRenderer or it's methods over the bridge.
+Instead provide a safe wrapper like below:
+
+```js
+contextBridge.exposeInMainWorld('app', {
+  onEvent: (cb) => ipcRenderer.on('foo', (e, ...args) => cb(args))
+})
+```
+
+### Removed: `renderer-process-crashed` event on `app`
+
+The `renderer-process-crashed` event on `app` has been removed.
+Use the new `render-process-gone` event instead.
+
+```js
+// Removed
+app.on('renderer-process-crashed', (event, webContents, killed) => { /* ... */ })
+
+// Replace with
+app.on('render-process-gone', (event, webContents, details) => { /* ... */ })
+```
+
+### Removed: `crashed` event on `WebContents` and `<webview>`
+
+The `crashed` events on `WebContents` and `<webview>` have been removed.
+Use the new `render-process-gone` event instead.
+
+```js
+// Removed
+win.webContents.on('crashed', (event, killed) => { /* ... */ })
+webview.addEventListener('crashed', (event) => { /* ... */ })
+
+// Replace with
+win.webContents.on('render-process-gone', (event, details) => { /* ... */ })
+webview.addEventListener('render-process-gone', (event) => { /* ... */ })
+```
+
+### Removed: `gpu-process-crashed` event on `app`
+
+The `gpu-process-crashed` event on `app` has been removed.
+Use the new `child-process-gone` event instead.
+
+```js
+// Removed
+app.on('gpu-process-crashed', (event, killed) => { /* ... */ })
+
+// Replace with
+app.on('child-process-gone', (event, details) => { /* ... */ })
+```
+
+### Behavior Changed: `BrowserView.setAutoResize` behavior on macOS
+
+In Electron 29, BrowserView is now a wrapper around the new [WebContentsView](api/web-contents-view.md) API.
+
+Previously, the `setAutoResize` function of the `BrowserView` API was backed by [autoresizing](https://developer.apple.com/documentation/appkit/nsview/1483281-autoresizingmask?language=objc) on macOS, and by a custom algorithm on Windows and Linux.
+For simple use cases such as making a BrowserView fill the entire window, the behavior of these two approaches was identical.
+However, in more advanced cases, BrowserViews would be autoresized differently on macOS than they would be on other platforms, as the custom resizing algorithm for Windows and Linux did not perfectly match the behavior of macOS's autoresizing API.
+The autoresizing behavior is now standardized across all platforms.
+
+If your app uses `BrowserView.setAutoResize` to do anything more complex than making a BrowserView fill the entire window, it's likely you already had custom logic in place to handle this difference in behavior on macOS.
+If so, that logic will no longer be needed in Electron 29 as autoresizing behavior is consistent.

+### 18. Avoid usage of the `file://` protocol and prefer usage of custom protocols
+
+You should serve local pages from a custom protocol instead of the `file://` protocol.
+
+#### Why?
+
+The `file://` protocol gets more privileges in Electron than in a web browser and even in
+browsers it is treated differently to http/https URLs. Using a custom protocol allows you
+to be more aligned with classic web url behavior while retaining even more control about
+what can be loaded and when.
+
+Pages running on `file://` have unilateral access to every file on your machine meaning
+that XSS issues can be used to load arbitrary files from the users machine. Using a custom
+protocol prevents issues like this as you can limit the protocol to only serving a specific
+set of files.
+
+#### How?
+
+Follow the [`protocol.handle`](../api/protocol.md#protocolhandlescheme-handler) examples to
+learn how to serve files / content from a custom protocol.
+
+### 19. Check which fuses you can change
+
+Electron ships with a number of options that can be useful but a large portion of
+applications probably don't need. In order to avoid having to build your own version of
+Electron, these can be turned off or on using [Fuses](./fuses.md).
+
+#### Why?
+
+Some fuses, like `runAsNode` and `nodeCliInspect`, allow the application to behave differently
+when run from the command line using specific environment variables or CLI arguments. These
+can be used to execute commands on the device through your application.
+
+This can let external scripts run commands that they potentially would not be allowed to, but
+that your application might have the rights for.
+
+#### How?
+
+We've made a module, [`@electron/fuses`](https://npmjs.com/package/@electron/fuses), to make
+flipping these fuses easy. Check out the README of that module for more details on usage and
+potential error cases, and refer to
+[How do I flip the fuses?](./fuses.md#how-do-i-flip-the-fuses) in our documentation.
