-## Modernization
-
-The Electron team is currently undergoing an initiative to modernize our API in a few concrete ways. These include: updating our modules to use idiomatic JS properties instead of separate `getPropertyX` and `setpropertyX`, converting callbacks to promises, and removing some other anti-patterns present in our APIs. The current status of the Promise initiative can be tracked in the [promisification](promisification.md) tracking file.
-
-As we work to perform these updates, we seek to create the least disruptive amount of change at any given time, so as many changes as possible will be introduced in a backward compatible manner and deprecated after enough time has passed to give users a chance to upgrade their API calls.
-
-This document and its child documents will be updated to reflect the latest status of our API changes.

+
+Process: [Main](../glossary.md#main-process)
+
+The `webFrameMain` module can be used to lookup frames across existing
+[`WebContents`](web-contents.md) instances. Navigation events are the common
+use case.
+
+```javascript
+const { BrowserWindow, webFrameMain } = require('electron')
+
+const win = new BrowserWindow({ width: 800, height: 1500 })
+win.loadURL('https://twitter.com')
+
+win.webContents.on(
+  'did-frame-navigate',
+  (event, url, isMainFrame, frameProcessId, frameRoutingId) => {
+    const frame = webFrameMain.fromId(frameProcessId, frameRoutingId)
+    if (frame) {
+      const code = 'document.body.innerHTML = document.body.innerHTML.replaceAll("heck", "h*ck")'
+      frame.executeJavaScript(code)
+    }
+  }
+)
+```
+
+You can also access frames of existing pages by using the `mainFrame` property
+of [`WebContents`](web-contents.md).
+
+```javascript
+const { BrowserWindow } = require('electron')
+
+async function main () {
+  const win = new BrowserWindow({ width: 800, height: 600 })
+  await win.loadURL('https://reddit.com')
+
+  const youtubeEmbeds = win.webContents.mainFrame.frames.filter((frame) => {
+    try {
+      const url = new URL(frame.url)
+      return url.host === 'www.youtube.com'
+    } catch {
+      return false
+    }
+  })
+
+  console.log(youtubeEmbeds)
+}
+
+main()
+```
+
+## Methods
+
+These methods can be accessed from the `webFrameMain` module:
+
+### `webFrameMain.fromId(processId, routingId)`
+
+* `processId` Integer - An `Integer` representing the internal ID of the process which owns the frame.
+* `routingId` Integer - An `Integer` representing the unique frame ID in the
+  current renderer process. Routing IDs can be retrieved from `WebFrameMain`
+  instances (`frame.routingId`) and are also passed by frame
+  specific `WebContents` navigation events (e.g. `did-frame-navigate`).
+
+Returns `WebFrameMain | undefined` - A frame with the given process and routing IDs,
+or `undefined` if there is no WebFrameMain associated with the given IDs.
+
+## Class: WebFrameMain
+
+Process: [Main](../glossary.md#main-process)
+
+### Instance Methods
+
+#### `frame.executeJavaScript(code[, userGesture])`
+
+* `code` String
+* `userGesture` Boolean (optional) - Default is `false`.
+
+Returns `Promise<unknown>` - A promise that resolves with the result of the executed
+code or is rejected if execution throws or results in a rejected promise.
+
+Evaluates `code` in page.
+
+In the browser window some HTML APIs like `requestFullScreen` can only be
+invoked by a gesture from the user. Setting `userGesture` to `true` will remove
+this limitation.
+
+#### `frame.reload()`
+
+Returns `boolean` - Whether the reload was initiated successfully. Only results in `false` when the frame has no history.
+
+#### `frame.send(channel, ...args)`
+
+* `channel` String
+* `...args` any[]
+
+Send an asynchronous message to the renderer process via `channel`, along with
+arguments. Arguments will be serialized with the [Structured Clone
+Algorithm][SCA], just like [`postMessage`][], so prototype chains will not be
+included. Sending Functions, Promises, Symbols, WeakMaps, or WeakSets will
+throw an exception.
+
+The renderer process can handle the message by listening to `channel` with the
+[`ipcRenderer`](ipc-renderer.md) module.
+
+#### `frame.postMessage(channel, message, [transfer])`
+
+* `channel` String
+* `message` any
+* `transfer` MessagePortMain[] (optional)
+
+Send a message to the renderer process, optionally transferring ownership of
+zero or more [`MessagePortMain`][] objects.
+
+The transferred `MessagePortMain` objects will be available in the renderer
+process by accessing the `ports` property of the emitted event. When they
+arrive in the renderer, they will be native DOM `MessagePort` objects.
+
+For example:
+
+```js
+// Main process
+const { port1, port2 } = new MessageChannelMain()
+webContents.mainFrame.postMessage('port', { message: 'hello' }, [port1])
+
+// Renderer process
+ipcRenderer.on('port', (e, msg) => {
+  const [port] = e.ports
+  // ...
+})
+```
+
+### Instance Properties
+
+#### `frame.url` _Readonly_
+
+A `string` representing the current URL of the frame.
+
+#### `frame.top` _Readonly_
+
+A `WebFrameMain | null` representing top frame in the frame hierarchy to which `frame`
+belongs.
+
+#### `frame.parent` _Readonly_
+
+A `WebFrameMain | null` representing parent frame of `frame`, the property would be
+`null` if `frame` is the top frame in the frame hierarchy.
+
+#### `frame.frames` _Readonly_
+
+A `WebFrameMain[]` collection containing the direct descendents of `frame`.
+
+#### `frame.framesInSubtree` _Readonly_
+
+A `WebFrameMain[]` collection containing every frame in the subtree of `frame`,
+including itself. This can be useful when traversing through all frames.
+
+#### `frame.frameTreeNodeId` _Readonly_
+
+An `Integer` representing the id of the frame's internal FrameTreeNode
+instance. This id is browser-global and uniquely identifies a frame that hosts
+content. The identifier is fixed at the creation of the frame and stays
+constant for the lifetime of the frame. When the frame is removed, the id is
+not used again.
+
+#### `frame.name` _Readonly_
+
+A `String` representing the frame name.
+
+#### `frame.osProcessId` _Readonly_
+
+An `Integer` representing the operating system `pid` of the process which owns this frame.
+
+#### `frame.processId` _Readonly_
+
+An `Integer` representing the Chromium internal `pid` of the process which owns this frame.
+This is not the same as the OS process ID; to read that use `frame.osProcessId`.
+
+#### `frame.routingId` _Readonly_
+
+An `Integer` representing the unique frame id in the current renderer process.
+Distinct `WebFrameMain` instances that refer to the same underlying frame will
+have the same `routingId`.

-# `window.open` Function
+# Opening windows from the renderer
 
-> Open a new window and load a URL.
+There are several ways to control how windows are created from trusted or
+untrusted content within a renderer. Windows can be created from the renderer in two ways:
 
-When `window.open` is called to create a new window in a web page, a new instance
-of [`BrowserWindow`](browser-window.md) will be created for the `url` and a proxy will be returned
-to `window.open` to let the page have limited control over it.
+- clicking on links or submitting forms adorned with `target=_blank`
+- JavaScript calling `window.open()`
 
-The proxy has limited standard functionality implemented to be
-compatible with traditional web pages. For full control of the new window
-you should create a `BrowserWindow` directly.
+In non-sandboxed renderers, or when `nativeWindowOpen` is false (the default), this results in the creation of a
+[`BrowserWindowProxy`](browser-window-proxy.md), a light wrapper around
+`BrowserWindow`.
 
-The newly created `BrowserWindow` will inherit the parent window's options by
-default. To override inherited options you can set them in the `features`
-string.
+However, when the `sandbox` (or directly, `nativeWindowOpen`) option is set, a
+`Window` instance is created, as you'd expect in the browser. For same-origin
+content, the new window is created within the same process, enabling the parent
+to access the child window directly. This can be very useful for app sub-windows that act
+as preference panels, or similar, as the parent can render to the sub-window
+directly, as if it were a `div` in the parent.
+
+Electron pairs this native Chrome `Window` with a BrowserWindow under the hood.
+You can take advantage of all the customization available when creating a
+BrowserWindow in the main process by using `webContents.setWindowOpenHandler()`
+for renderer-created windows.
+
+BrowserWindow constructor options are set by, in increasing precedence

+## Planned Breaking API Changes (14.0)
+
+### API Changed: `window.(open)`
+
+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`.
+
+If you were using this parameter to set the title of a window, you can instead use [win.setTitle(title)](https://www.electronjs.org/docs/api/browser-window#winsettitletitle).
+
+### Removed: `worldSafeExecuteJavaScript`
+
+In Electron 14, `worldSafeExecuteJavaScript` will be removed.  There is no alternative, please
+ensure your code works with this property enabled.  It has been enabled by default since Electron
+12.
+
+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.
+
+## Planned Breaking API Changes (13.0)
+
+### API Changed: `session.setPermissionCheckHandler(handler)`
+
+The `handler` methods first parameter was previously always a `webContents`, it can now sometimes be `null`.  You should use the `requestingOrigin`, `embeddingOrigin` and `securityOrigin` properties to respond to the permission check correctly.  As the `webContents` can be `null` it can no longer be relied on.
+
+```js
+// Old code
+session.setPermissionCheckHandler((webContents, permission) => {
+  if (webContents.getURL().startsWith('https://google.com/') && permission === 'notification') {
+    return true
+  }
+  return false
+})
+
+// Replace with
+session.setPermissionCheckHandler((webContents, permission, requestingOrigin) => {
+  if (new URL(requestingOrigin).hostname === 'google.com' && permission === 'notification') {
+    return true
+  }
+  return false
+})
