+
+* **MSIX packages**: If your app is running as an MSIX package (created with [electron-windows-msix][msix-lib] and detected via [`process.windowsStore`](process.md#processwindowsstore-readonly)),

+### Linux

 `desktopCapturer.getSources(options)` only returns a single source on Linux when using Pipewire.
 
 PipeWire supports a single capture for both screens and windows. If you request the window and screen type, the selected source will be returned as a window capture.
 
-`navigator.mediaDevices.getUserMedia` does not work on macOS for audio capture due to a fundamental limitation whereby apps that want to access the system's audio require a [signed kernel extension](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/KernelExtensions/KernelExtensions.html). Chromium, and by extension Electron, does not provide this.
+---
 
-It is possible to circumvent this limitation by capturing system audio with another macOS app like Soundflower and passing it through a virtual audio input device. This virtual device can then be queried with `navigator.mediaDevices.getUserMedia`.
+### MacOS versions 14.2 or higher
+
+`NSAudioCaptureUsageDescription` Info.plist key must be added in-order for audio to be captured by `desktopCapturer`. If instead you are running electron from another program like a terminal or IDE then that parent program must contain the Info.plist key.
+
+This is in order to facillitate use of Apple's new [CoreAudio Tap API](https://developer.apple.com/documentation/CoreAudio/capturing-system-audio-with-core-audio-taps#Configure-the-sample-code-project) by Chromium.
+
+> [!WARNING]
+> Failure of `desktopCapturer` to start an audio stream due to `NSAudioCaptureUsageDescription` permission not present will still create a dead audio stream however no warnings or errors are displayed.
+
+As of electron `v39.0.0-beta.4` Chromium [made Apple's new `CoreAudio Tap API` the default](https://source.chromium.org/chromium/chromium/src/+/ad17e8f8b93d5f34891b06085d373a668918255e) for desktop audio capture. There is no fallback to the older `Screen & System Audio Recording` permissions system even if [CoreAudio Tap API](https://developer.apple.com/documentation/CoreAudio/capturing-system-audio-with-core-audio-taps) stream creation fails.
+
+If you need to continue using `Screen & System Audio Recording` permissions for `desktopCapturer` on macOS versions 14.2 and later, you can apply a chromium feature flag to force use of that older permissions system:
+
+```js
+// main.js (right beneath your require/import statments)
+app.commandLine.appendSwitch('disable-features', 'MacCatapLoopbackAudioForScreenShare')
+```
+
+---
+
+### MacOS versions 12.7.6 or lower
+
+`navigator.mediaDevices.getUserMedia` does not work on macOS versions 12.7.6 and prior for audio capture due to a fundamental limitation whereby apps that want to access the system's audio require a [signed kernel extension](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/KernelExtensions/KernelExtensions.html). Chromium, and by extension Electron, does not provide this. Only in macOS 13 and onwards does Apple provide APIs to capture desktop audio without the need for a signed kernel extension.

+### Behavior Changed: `NSAudioCaptureUsageDescription` should be included in your app's Info.plist file to use `desktopCapturer` (🍏 macOS ≥14.2)
+
+Per [Chromium update](https://source.chromium.org/chromium/chromium/src/+/ad17e8f8b93d5f34891b06085d373a668918255e) which enables Apple's newer [CoreAudio Tap API](https://developer.apple.com/documentation/CoreAudio/capturing-system-audio-with-core-audio-taps#Configure-the-sample-code-project) by default, you now must have `NSAudioCaptureUsageDescription` defined in your `Info.plist` to use `desktopCapturer`.
+
+Electron's `desktopCapturer` will create a dead audio stream if the new permission is absent however no errors or warnings will occur. This is partially a side-effect of Chromium not falling back to the older `Screen & System Audio Recording` permissions system if the new system fails.
+
+To restore previous behavior:
+
+```js
+// main.js (right beneath your require/import statments)
+app.commandLine.appendSwitch(
+  'disable-features',
+  'MacCatapLoopbackAudioForScreenShare'

 ### Behavior Changed: shared texture OSR `paint` event data structure
 
 When using shared texture offscreen rendering feature, the `paint` event now emits a more structured object.

+Subject: Avoid stale iteration in CSSFontFeatureValuesMap
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+To avoid invalid iterator state, take a snapshot of the
+map when creating the iteration source. This addresses
+the immediate problem of iterating while modifying.

+Remaining work tracked in https://crbug.com/483936078

+Subject: [graphite] Handle out of order recording errors
+
+Explicitly handle out of order recording errors to crash just like async
+shader compile failed errors. Also, emit the insert status to an UMA
+histogram at 1% subsampling and log all error statuses at runtime.

+Subject: Ozone/Wayland: Treat DND drop performed with NONE action as a
+ cancellation
+
+According to the Wayland protocol, a "drop performed" event can be
+followed with a `cancelled` event. This is the behavior of compositors
+like KWin.
+
+We were always treating "drop performed" as a completed drop. This
+change corrects the logic to pass `DragResult::kCancelled` in this
+scenario.

+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
+From: Alex Rudenko <alexrudenko@chromium.org>
+Date: Thu, 20 Nov 2025 11:18:30 +0100
+Subject: Fix element tree flickering with node inspection
+
+Regressed in https://crrev.com/c/6888910. The highlighting in the tree
+outline emits the INSPECT_MODE_WILL_BE_TOGGLED on the overlay model
+causing the tree to clear the highlight immediately. This CL
+recovers the logic missed in the https://crrev.com/c/6888910
+to prevent re-entrancy during highlighting.
+
+Fixed: 462120622
+Change-Id: I08af098f7a142085c2fb16511031855623e07c4b
