 ### API Changed: `shell.openItem` is now `shell.openPath`
 
 The `shell.openItem` API has been replaced with an asynchronous `shell.openPath` API.

+# Device Access
+
+Like Chromium based browsers, Electron provides access to device hardware
+through web APIs.  For the most part these APIs work like they do in a browser,
+but there are some differences that need to be taken into account.  The primary
+difference between Electron and browsers is what happens when device access is
+requested.  In a browser, users are presented with a popup where they can grant
+access to an individual device.  In Electron APIs are provided which can be
+used by a developer to either automatically pick a device or prompt users to
+pick a device via a developer created interface.
+
+## Web Bluetooth API
+
+The [Web Bluetooth API](https://web.dev/bluetooth/) can be used to communicate
+with bluetooth devices. In order to use this API in Electron, developers will
+need to handle the [`select-bluetooth-device` event on the webContents](../api/web-contents.md#event-select-bluetooth-device)
+associated with the device request.
+
+### Example
+
+This example demonstrates an Electron application that automatically selects
+the first available bluetooth device when the `Test Bluetooth` button is
+clicked.
+
+```javascript fiddle='docs/fiddles/features/web-bluetooth'
+
+```
+
+## WebHID API
+
+The [WebHID API](https://web.dev/hid/) can be used to access HID devices such
+as keyboards and gamepads.  Electron provides several APIs for working with
+the WebHID API:
+
+* The [`select-hid-device` event on the Session](../api/session.md#event-select-hid-device)
+  can be used to select a HID device when a call to
+  `navigator.hid.requestDevice` is made.  Additionally the [`hid-device-added`](../api/session.md#event-hid-device-added)
+  and [`hid-device-removed`](../api/session.md#event-hid-device-removed) events
+  on the Session can be used to handle devices being plugged in or unplugged during the
+  `navigator.hid.requestDevice` process.
+* [`ses.setDevicePermissionHandler(handler)`](../api/session.md#sessetdevicepermissionhandlerhandler)
+  can be used to provide default permissioning to devices without first calling
+  for permission to devices via `navigator.hid.requestDevice`.  Additionally,
+  the default behavior of Electron is to store granted device permision through
+  the lifetime of the corresponding WebContents.  If longer term storage is
+  needed, a developer can store granted device permissions (eg when handling
+  the `select-hid-device` event) and then read from that storage with
+  `setDevicePermissionHandler`.
+* [`ses.setPermissionCheckHandler(handler)`](../api/session.md#sessetpermissioncheckhandlerhandler)
+  can be used to disable HID access for specific origins.
+
+### Blocklist
+
+By default Electron employs the same [blocklist](https://github.com/WICG/webhid/blob/main/blocklist.txt)
+used by Chromium.  If you wish to override this behavior, you can do so by
+setting the `disable-hid-blocklist` flag:
+
+```javascript
+app.commandLine.appendSwitch('disable-hid-blocklist')
+```
+
+### Example
+
+This example demonstrates an Electron application that automatically selects
+HID devices through [`ses.setDevicePermissionHandler(handler)`](../api/session.md#sessetdevicepermissionhandlerhandler)
+and through [`select-hid-device` event on the Session](../api/session.md#event-select-hid-device)
+when the `Test WebHID` button is clicked.
+
+```javascript fiddle='docs/fiddles/features/web-hid'
+
+```
+
+## Web Serial API
+
+The [Web Serial API](https://web.dev/serial/) can be used to access serial
+devices that are connected via serial port, USB, or Bluetooth.  In order to use
+this API in Electron, developers will need to handle the
+[`select-serial-port` event on the Session](../api/session.md#event-select-serial-port)
+associated with the serial port request.
+
+There are several additional APIs for working with the Web Serial API:
+
+* The [`serial-port-added`](../api/session.md#event-serial-port-added)
+  and [`serial-port-removed`](../api/session.md#event-serial-port-removed) events
+  on the Session can be used to handle devices being plugged in or unplugged during the
+  `navigator.serial.requestPort` process.
+* [`ses.setPermissionCheckHandler(handler)`](../api/session.md#sessetpermissioncheckhandlerhandler)
+  can be used to disable serial access for specific origins.
+
+### Example
+
+This example demonstrates an Electron application that automatically selects
+the first available Arduino Uno serial device (if connected) through
+[`select-serial-port` event on the Session](../api/session.md#event-select-serial-port)
+when the `Test Web Serial` button is clicked.

-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.

+Subject: fix: crash creating private key with unsupported algorithm
+
+This patch fixes an issue where some calls to crypto.createPrivateKey
+made with algorithms unsupported by BoringSSL cause a crash when invoking
+methods on their return values. This was happening because BoringSSL
+shims some algorithms but doesn't implement them and so attempted to
+created keys with them will fail (see https://source.chromium.org/chromium/chromium/src/+/main:third_party/boringssl/src/include/openssl/evp.h;l=835-837?q=ed448&ss=chromium)
+
+Node.js returned false in initEdRaw (see: https://github.com/nodejs/node/blob/20cf47004e7801ede1588d2de8785c0100f6ab38/src/crypto/crypto_keys.cc#L1106)
+but then did nothing with the return value, meaning that if no pkey was
+created successfully that a key object was still returned but attempts
+to use the data_ field would crash the process as data_ was never
+assigned. This is fixed by checking the return value of initEdRaw at the
+JavaScript level and throwing an error if the function returns false.
+
+This patch will be upstreamed in some form.
