+## 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.

+# `sandbox` Option
+
+> Create a browser window with a sandboxed renderer. With this
+option enabled, the renderer must communicate via IPC to the main process in order to access node APIs.
+
+One of the key security features of Chromium is that all blink rendering/JavaScript
+code is executed within a sandbox. This sandbox uses OS-specific features to ensure
+that exploits in the renderer process cannot harm the system.
+
+In other words, when the sandbox is enabled, the renderers can only make changes
+to the system by delegating tasks to the main process via IPC.
+[Here's](https://www.chromium.org/developers/design-documents/sandbox) more
+information about the sandbox.
+
+Since a major feature in Electron is the ability to run Node.js in the
+renderer process (making it easier to develop desktop applications using web
+technologies), the sandbox is disabled by electron. This is because
+most Node.js APIs require system access. `require()` for example, is not
+possible without file system permissions, which are not available in a sandboxed
+environment.
+
+Usually this is not a problem for desktop applications since the code is always
+trusted, but it makes Electron less secure than Chromium for displaying
+untrusted web content. For applications that require more security, the
+`sandbox` flag will force Electron to spawn a classic Chromium renderer that is
+compatible with the sandbox.
+
+A sandboxed renderer doesn't have a Node.js environment running and doesn't
+expose Node.js JavaScript APIs to client code. The only exception is the preload script,
+which has access to a subset of the Electron renderer API.
+
+Another difference is that sandboxed renderers don't modify any of the default
+JavaScript APIs. Consequently, some APIs such as `window.open` will work as they
+do in Chromium (i.e. they do not return a [`BrowserWindowProxy`](browser-window-proxy.md)).
+
+## Example
+
+To create a sandboxed window, pass `sandbox: true` to `webPreferences`:
+
+```js
+let win
+app.whenReady().then(() => {
+  win = new BrowserWindow({
+    webPreferences: {
+      sandbox: true
+    }
+  })
+  win.loadURL('http://google.com')
+})
+```
+
+In the above code the [`BrowserWindow`](browser-window.md) that was created has Node.js disabled and can communicate
+only via IPC. The use of this option stops Electron from creating a Node.js runtime in the renderer. Also,
+within this new window `window.open` follows the native behavior (by default Electron creates a [`BrowserWindow`](browser-window.md)
+and returns a proxy to this via `window.open`).
+
+[`app.enableSandbox`](app.md#appenablesandbox) can be used to force `sandbox: true` for all `BrowserWindow` instances.
+
+```js
+let win
+app.enableSandbox()
+app.whenReady().then(() => {
+  // no need to pass `sandbox: true` since `app.enableSandbox()` was called.
+  win = new BrowserWindow()
+  win.loadURL('http://google.com')
+})
+```
+
+## Preload
+
+An app can make customizations to sandboxed renderers using a preload script.
+Here's an example:
+
+```js
+let win
+app.whenReady().then(() => {
+  win = new BrowserWindow({
+    webPreferences: {
+      sandbox: true,
+      preload: path.join(app.getAppPath(), 'preload.js')
+    }
+  })
+  win.loadURL('http://google.com')
+})
+```
+
+and preload.js:
+
+```js
+// This file is loaded whenever a javascript context is created. It runs in a
+// private scope that can access a subset of Electron renderer APIs. Without
+// contextIsolation enabled, it's possible to accidentally leak privileged
+// globals like ipcRenderer to web content.
+const { ipcRenderer } = require('electron')
+
+const defaultWindowOpen = window.open
+
+window.open = function customWindowOpen (url, ...args) {
+  ipcRenderer.send('report-window-open', location.origin, url, args)
+  return defaultWindowOpen(url + '?from_electron=1', ...args)
+}
+```
+
+Important things to notice in the preload script:
+
+- Even though the sandboxed renderer doesn't have Node.js running, it still has
+  access to a limited node-like environment: `Buffer`, `process`, `setImmediate`,
+  `clearImmediate` and `require` are available.
+- The preload script must be contained in a single script, but it is possible to have
+  complex preload code composed with multiple modules by using a tool like
+  webpack or browserify. An example of using browserify is below.
+
+To create a browserify bundle and use it as a preload script, something like
+the following should be used:
+
+```sh
+  browserify preload/index.js \
+    -x electron \
+    --insert-global-vars=__filename,__dirname -o preload.js
+```
+
+The `-x` flag should be used with any required module that is already exposed in
+the preload scope, and tells browserify to use the enclosing `require` function
+for it. `--insert-global-vars` will ensure that `process`, `Buffer` and
+`setImmediate` are also taken from the enclosing scope(normally browserify
+injects code for those).
+
+Currently the `require` function provided in the preload scope exposes the
+following modules:
+
+- `electron`
+  - `crashReporter`
+  - `desktopCapturer`
+  - `ipcRenderer`
+  - `nativeImage`
+  - `webFrame`
+- `events`
+- `timers`
+- `url`
+
+More may be added as needed to expose more Electron APIs in the sandbox.
+
+## Rendering untrusted content
+
+Rendering untrusted content in Electron is still somewhat uncharted territory,
+though some apps are finding success (e.g. Beaker Browser). Our goal is to get
+as close to Chrome as we can in terms of the security of sandboxed content, but
+ultimately we will always be behind due to a few fundamental issues:
+
+1. We do not have the dedicated resources or expertise that Chromium has to
+   apply to the security of its product. We do our best to make use of what we
+   have, to inherit everything we can from Chromium, and to respond quickly to
+   security issues, but Electron cannot be as secure as Chromium without the
+   resources that Chromium is able to dedicate.
+2. Some security features in Chrome (such as Safe Browsing and Certificate
+   Transparency) require a centralized authority and dedicated servers, both of
+   which run counter to the goals of the Electron project. As such, we disable
+   those features in Electron, at the cost of the associated security they
+   would otherwise bring.
+3. There is only one Chromium, whereas there are many thousands of apps built
+   on Electron, all of which behave slightly differently. Accounting for those
+   differences can yield a huge possibility space, and make it challenging to
+   ensure the security of the platform in unusual use cases.
+4. We can't push security updates to users directly, so we rely on app vendors
+   to upgrade the version of Electron underlying their app in order for
+   security updates to reach users.
+
+Here are some things to consider before rendering untrusted content:
+
+- A preload script can accidentally leak privileged APIs to untrusted code,
+  unless [`contextIsolation`](../tutorial/security.md#3-enable-context-isolation-for-remote-content)
+  is also enabled.
+- Some bug in the V8 engine may allow malicious code to access the renderer
+  preload APIs, effectively granting full access to the system through the
+  `remote` module. Therefore, it is highly recommended to [disable the `remote`
+  module](../tutorial/security.md#15-disable-the-remote-module).
+  If disabling is not feasible, you should selectively [filter the `remote`
+  module](../tutorial/security.md#16-filter-the-remote-module).
+- While we make our best effort to backport Chromium security fixes to older
+  versions of Electron, we do not make a guarantee that every fix will be
+  backported. Your best chance at staying secure is to be on the latest stable
+  version of Electron.

-In Electron 14, `worldSafeExecuteJavaScript` will be removed.  There is no alternative, please

-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.
