 # Electron Release Timelines
 
+Special notes:
+
 * The `-beta.1` and `stable` dates are our solid release dates.
 * We strive for weekly beta releases, however we often release more betas than scheduled.
 * All dates are our goals but there may be reasons for adjusting the stable deadline, such as security bugs.
 * Take a look at the [5.0.0 Timeline blog post](https://electronjs.org/blog/electron-5-0-timeline) for info about publicizing our release dates.
 * Since Electron 6.0, we've been targeting every other Chromium version and releasing our stable on the same day as Chrome stable. You can reference Chromium's release schedule [here](https://chromiumdash.appspot.com/schedule). See [Electron's new release cadence blog post](https://www.electronjs.org/blog/12-week-cadence) for more details on our release schedule.
+* Electron 15.0 only will include a special Alpha release. Starting in Electron 16.0, we will release on an 8-week cadence. See [Electron's new 8-week cadence blog post](https://www.electronjs.org/blog/8-week-cadence) for more details.

+# Launching Your Electron App From A URL In Another App
+
+## Overview
+
+<!-- ✍ Update this section if you want to provide more details -->
+
+This guide will take you through the process of setting your electron app as the default
+handler for a specific [protocol](https://www.electronjs.org/docs/api/protocol).
+
+By the end of this tutorial, we will have set our app to intercept and handle
+any clicked URLs that start with a specific protocol. In this guide, the protocol
+we will use will be "`electron-fiddle://`".
+
+## Examples
+
+### Main Process (main.js)
+
+First we will import the required modules from `electron`. These modules help control our application life and create a native browser window.
+
+```js
+const { app, BrowserWindow, shell } = require('electron')
+const path = require('path')
+```
+
+Next, we will proceed to register our application to handle all "`electron-fiddle://`" protocols.
+
+```js
+if (process.defaultApp) {
+  if (process.argv.length >= 2) {
+    app.setAsDefaultProtocolClient('electron-fiddle', process.execPath, [path.resolve(process.argv[1])])
+  }
+} else {
+  app.setAsDefaultProtocolClient('electron-fiddle')
+}
+```
+
+We will now define the function in charge of creating our browser window and load our application's `index.html` file.
+
+```js
+function createWindow () {
+  // Create the browser window.
+  mainWindow = new BrowserWindow({
+    width: 800,
+    height: 600,
+    webPreferences: {
+      preload: path.join(__dirname, 'preload.js')
+    }
+  })
+
+  mainWindow.loadFile('index.html')
+}
+```
+
+In this next step, we will create our  `BrowserWindow` and tell our application how to handle an event in which an external protocol is clicked.
+
+This code will be different in WindowsOS compared to MacOS and Linux. This is due to Windows requiring additional code in order to open the contents of the protocol link within the same electron instance. Read more about this [here](https://www.electronjs.org/docs/api/app#apprequestsingleinstancelock).
+
+### Windows code:
+
+```js
+const gotTheLock = app.requestSingleInstanceLock()
+
+if (!gotTheLock) {
+  app.quit()
+} else {
+  app.on('second-instance', (event, commandLine, workingDirectory) => {
+    // Someone tried to run a second instance, we should focus our window.
+    if (mainWindow) {
+      if (mainWindow.isMinimized()) mainWindow.restore()
+      mainWindow.focus()
+    }
+  })
+
+  // Create mainWindow, load the rest of the app, etc...
+  app.whenReady().then(() => {
+    createWindow()
+  })
+
+  // handling the protocol. In this case, we choose to show an Error Box.
+  app.on('open-url', (event, url) => {
+    dialog.showErrorBox('Welcome Back', `You arrived from: ${url}`)
+  })
+}
+```
+
+### MacOS and Linux code:
+
+```js
+// This method will be called when Electron has finished
+// initialization and is ready to create browser windows.
+// Some APIs can only be used after this event occurs.
+app.whenReady().then(() => {
+  createWindow()
+})
+
+// handling the protocol. In this case, we choose to show an Error Box.
+app.on('open-url', (event, url) => {
+  dialog.showErrorBox('Welcome Back', `You arrived from: ${url}`)
+})
+```
+
+Finally, we will add some additional code to handle when someone closes our application
+
+```js
+// Quit when all windows are closed, except on macOS. There, it's common
+// for applications and their menu bar to stay active until the user quits
+// explicitly with Cmd + Q.
+app.on('window-all-closed', function () {
+  if (process.platform !== 'darwin') app.quit()
+})
+```
+
+## Important Note:
+
+### Packaging
+
+This feature will only work on macOS when your app is packaged. It will not work when you're launching it in development from the command-line. When you package your app you'll need to make sure the macOS `plist` for the app is updated to include the new protocol handler. If you're using [`electron-packager`](https://github.com/electron/electron-packager) then you
+can add the flag `--extend-info` with a path to the `plist` you've created. The one for this app is below:
+
+### Plist
+
+```XML
+  <p>
+  <h5>macOS plist</h5>
+  <pre><code>
+    <?xml version="1.0" encoding="UTF-8"?>
+        <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+            <plist version="1.0">
+                <dict>
+                    <key>CFBundleURLTypes</key>
+                    <array>
+                        <dict>
+                            <key>CFBundleURLSchemes</key>
+                            <array>
+                                <string>electron-api-demos</string>
+                            </array>
+                            <key>CFBundleURLName</key>
+                            <string>Electron API Demos Protocol</string>
+                        </dict>
+                    </array>
+                    <key>ElectronTeamID</key>
+                    <string>VEKTX9H2N7</string>
+                </dict>
+            </plist>
+        </code>
+    </pre>
+  <p>
+```
+
+## Conclusion
+
+After you start your electron app, you can now enter in a URL in your browser that contains the custom protocol, for example `"electron-fiddle://open"` and observe that the application will respond and show an error dialog box.
+
+<!--
+    Because Electron examples usually require multiple files (HTML, CSS, JS
+    for the main and renderer process, etc.), we use this custom code block
+    for Fiddle (https://www.electronjs.org/fiddle).
+    Please modify any of the files in the referenced folder to fit your
+    example.
+    The content in this codeblock will not be rendered in the website so you
+    can leave it empty.

+Subject: fix: sync EVP_get_cipherbynid and EVP_get_cipherbyname
+
+This commit syncs the results of EVP_get_cipherbynid and
+EVP_get_cipherbyname. Node.js logic assumes that calling EVP_get_cipherbynid
+on a NID returned from a call to `getCipherInfo` with the cipher name
+will return the same cipher information - this assumption holds in OpenSSL
+and should also hold in BoringSSL.
+
+This will be upstreamed.

+Subject: chore: add gin::wrappable wrapperinfo crash key
+
+This patch adds an additional crash key for gin::Wrappable, to help
+debug a crash that is occurring during garbage collection in SecondWeakCallback.
+
+The crash seems to be due to a class that is holding a reference to
+gin::Wrappable even after being deleted. This added crash key compares
+the soon-to-be-deleted WrapperInfo with known WrapperInfo components to
+help determine where the crash originated from.
+
+This patch should not be upstreamed, and can be removed in Electron 15 and
+beyond once we identify the cause of the crash.

patches/chromium/disable_compositor_recycling.patch

@@ -6,7 +6,7 @@ Subject: fix: disabling compositor recycling
 Compositor recycling is useful for Chrome because there can be many tabs and spinning up a compositor for each one would be costly. In practice, Chrome uses the parent compositor code path of browser_compositor_view_mac.mm; the NSView of each tab is detached when it's hidden and attached when it's shown. For Electron, there is no parent compositor, so we're forced into the "own compositor" code path, which seems to be non-optimal and pretty ruthless in terms of the release of resources. Electron has no real concept of multiple tabs per window, so it should be okay to disable this ruthless recycling altogether in Electron.
