 ## Example use cases
 
+### Setting up a MessageChannel between two renderers
+
+In this example, the main process sets up a MessageChannel, then sends each port
+to a different renderer. This allows renderers to send messages to each other
+without needing to use the main process as an in-between.
+
+```js title='main.js (Main Process)'
+const { BrowserWindow, app, MessageChannelMain } = require('electron')
+
+app.whenReady().then(async () => {
+  // create the windows.
+  const mainWindow = new BrowserWindow({
+    show: false,
+    webPreferences: {
+      contextIsolation: false,
+      preload: 'preloadMain.js'
+    }
+  })
+
+  const secondaryWindow = BrowserWindow({
+    show: false,
+    webPreferences: {
+      contextIsolation: false,
+      preload: 'preloadSecondary.js'
+    }
+  })
+
+  // set up the channel.
+  const { port1, port2 } = new MessageChannelMain()
+
+  // once the webContents are ready, send a port to each webContents with postMessage.
+  mainWindow.once('ready-to-show', () => {
+    mainWindow.webContents.postMessage('port', null, [port1])
+  })
+
+  secondaryWindow.once('ready-to-show', () => {
+    secondaryWindow.webContents.postMessage('port', null, [port2])
+  })
+})
+```
+
+Then, in your preload scripts you receive the port through IPC and set up the
+listeners.
+
+```js title='preloadMain.js and preloadSecondary.js (Preload scripts)'
+const { ipcRenderer } = require('electron')
+
+ipcRenderer.on('port', e => {
+  // port received, make it globally available.
+  window.electronMessagePort = e.ports[0]
+
+  window.electronMessagePort.onmessage = messageEvent => {
+    // handle message
+  }
+})
+```
+
+In this example messagePort is bound to the `window` object directly. It is better
+to use `contextIsolation` and set up specific contextBridge calls for each of your
+expected messages, but for the simplicity of this example we don't. You can find an
+example of context isolation further down this page at [Communicating directly between the main process and the main world of a context-isolated page](#communicating-directly-between-the-main-process-and-the-main-world-of-a-context-isolated-page)
+
+That means window.messagePort is globally available and you can call
+`postMessage` on it from anywhere in your app to send a message to the other
+renderer.
+
+```js title='renderer.js (Renderer Process)'
+// elsewhere in your code to send a message to the other renderers message handler
+window.electronMessagePort.postmessage('ping')

+Subject: M104: Vulkan: Fix garbage collection vs outside-RP-only flush
+
+In https://chromium-review.googlesource.com/c/angle/angle/+/3379231, an
+optimization was implemented such that the excessive recorded texture
+uploads would get flushed early and submitted.  This caused a
+use-after-free bug in the following situation:
+
+* Draw with pipeline A
+* Delete A <--- this puts A in the Context garbage list
+* Upload a lot of data
+
+At this point, the flush threshold could pass and the commands recorded
+outside of the render pass up to this point would be submitted.
+Associated with this submission was the current garbage, including
+pipeline A.  However, the render pass that uses pipeline A is still not
+submitted.
+
+Now if after some time the render pass is still open, but the "completed
+commands" are checked (another set of uploads causing another
+submission, a query status check, etc), the garbage can be cleaned up.
+
+When the render pass closes next and is submitted, the implementation
+attempts to use the pipeline, which is already deleted.
+
+In this change, outside-render-pass-only submissions no longer reference
+the current garbage.  This has the side effect that the temporary
+buffers used for uploading texture data won't be released early.  A
+future optimization may want to separate the garbage list in ContextVk
+to render pass and outside render pass garbage.

+Subject: M104: Vulkan: Fix xfb buffer redefine to smaller size
+
+In 89e11878b275b15735eaf273ababfa6fd43a2e3d, a use-after-free bug was
+fixed where glBufferData redefined a buffer, leading to a change in
+storage.  This was only tested for the case where the new buffer was
+larger than the old buffer.
+
+When the new buffer is smaller however, another issue remains where the
+buffer size as cached by the transform feedback object used the old
+object's size.  This is worked around in this change, with a fix for the
+real issue (that the buffer state is updated after calling into the
+backend instead of before) coming up.

+Subject: Avoid layout roots in subtrees skipped for style recalc
+
+Layout roots are laid out from inner to outer in LocalFrameView. DOM
+mutations may have added layout roots inside size container subtrees
+before style recalc. If we decide to postpone style recalc until layout
+of the size container, it means we may try to layout a root inside a
+subtree skipped for style recalc. That causes a DCHECK and possibly
+other issues.
+
+This also fixes the use-after-poison issue 1365330.
+

+Subject: Add CSSTokenizer-created strings to CSSVariableData's backing strings
+
+When computing the value of a registered custom property, we create
+a CSSVariableData object equivalent to the computed CSSValue by
+serializing that CSSValue to a String, then tokenizing that value.
+
+The problem is that CSSTokenizer can create *new* string objects
+during the tokenization process (see calls to CSSTokenizer::
+RegisterString), without communicating that fact to the call-site.
+
+Therefore, this CL adds a way to access those strings so they can
+be added to the backing strings of the CSSVariableData.
+
+Also added a DCHECK to verify that we don't have any tokens with
+non-backed string pointers.

+Subject: Fix UAF on network::URLLoader
+
+network::URLLoader::SetUpUpload calls NotifyCompleted asynchronously,
+as it can be called in the constructor and we don't want to run
+NotifyCompleted in the constructor.
+
+The problem is that it attaches a raw pointer to the method, which leads to a use-after-free problem if the URLLoader is destructed before
+NotifyCompleted is called.
+
+Use weak pointers instead of raw pointers to avoid the problem.

+Subject: Sanitize default file name in windows select file dialog
+
+On windows, '%' is a special character and can be used for environment
+variables. So if the default file name is '%DATADIR%', it can actually
+refer to another directory and thus causing weird behaviors.
+And '%' cannot be escaped when used in the file dialog. Both "^%" and
+"%%" don't work. This CL mitigates the issue by replacing '%' with '_'.
+This only affects the default file name when showing the dialog. Power
+users can still change the file name by adding '%' if needed.
