* docs: clarify ASAR integrity is supported in MAS builds
Add a note to the ASAR integrity documentation explicitly stating
that this feature is fully supported and recommended in Mac App
Store builds. While MAS-installed apps have system-level protections,
ASAR integrity provides an additional security layer and is important
for MAS builds distributed outside the Mac App Store.

* docs: clarify ASAR integrity support for MAS builds
Updates the ASAR integrity documentation to explicitly mention that
it is supported and recommended in Mac App Store builds. Clarifies
that while MAS-installed apps have system-level protections (Resources
folder owned by root), ASAR integrity is especially important when
distributing MAS builds through other channels like direct download,
since those installations won't have the read-only protections.

Chromium used to only implement pointer lock on Wayland in
Chrome-specific code, and this prevented Electron from making use of it.
This has been fixed on chromium main, so backport this as a patch to
Electron.
* Revert "fix: fix Windows MSIX release build errors (#49613)"
This reverts commit 4b5d5f9dd5.
Co-authored-by: Keeley Hammond <khammond@slack-corp.com>
* refactor: use WRL ComPtr pattern for MSIX to avoid exception handling
The MSIX auto-updater code was using C++/WinRT (winrt::* namespace), which requires exception handling (/EHsc). Mixing exception and non-exception handling code in the same binary is problematic at runtime. This commit refactors electron_api_msix_updater.cc to use an upstream Chromium pattern and eliminates the need for special exception handling build flags

fix: clean up old staged updates before downloading new update
When checkForUpdates() is called while an update is already staged,
Squirrel creates a new temporary directory for the download without
cleaning up the old one. This can lead to disk usage growth when
new versions are released while the app hasn't restarted.
This adds a force parameter to pruneUpdateDirectories that bypasses
the AwaitingRelaunch state check. This is called before creating a
new temp directory, ensuring old staged updates are cleaned up.

docs: Update shell.md: Document that shell.trashItem requires backslashes
In Windows many functions relating to files (e.g. shell.openItem, the Node fs functions, as well as native Win32 APIs) will accept either type of slash / or \ as a folder separator.
shell.trashItem does not work with / as folder separator in Windows. This documentation change explains that.

Starting from Chromium 134.0.6989.0 (Electron 35.0.0-beta.5), the
NativeWidgetMacNSWindow class overrides accessibilityDocument to return
the web content URL from the accessibility tree, but doesn't fall back
to NSWindow's default behavior when that URL is empty.
This broke Electron's setRepresentedFilename() API - the file path was
still set on the NSWindow, but no longer exposed via the AXDocument
accessibility attribute that screen readers use.
This fix adds an accessibilityDocument override in ElectronNSWindow that
checks representedFilename first, falling back to Chromium's behavior
for web content URLs.

In 6399527761 we changed the path strings
that `node_modules.cc` operates on from single-byte to wide strings.
Unfortunately this means that `generic_path()` that the
"fix: ensure TraverseParent bails on resource path exit" patch was
calling was no longer a safe method to call on Windows if the underlying
string has unicode characters in it.
Here we fix it by using `ConvertGenericPathToUTF8` from the Node.js
internal utilities.

* docs(timelines): Correct v40.0.0 stable release date
On the Electron Timelines tutorial page (/docs/latest/tutorial/electron-timelines), there is a clear typo in the release schedule for v40.0.0.
The table currently lists the dates as:
* Alpha: 2025-Oct-30
* Beta: 2025-Dec-03
* **Stable: 2025-Oct-28**
This is logically incorrect, as the 'Stable' release date (Oct 28) is listed *before* both the 'Alpha' (Oct 30) and 'Beta' (Dec 03) dates for the same version.
This appears to be a copy-paste error, as the 'Stable' date (2025-Oct-28) is identical to the 'Stable' date for the v39.0.0 release in the preceding row.
This commit updates the 'Stable' date for v40.0.0 to its correct value, ensuring the timeline is accurate and logical.

trap handlers will be initialized once the user script starts
but before app#ready. Wasm compilation before that phase will
break trap handler registeration due to the check in
v8::internal::wasm::UpdateComputedInformation. For some reason
this issue was only visible in <= 39-x-y when pdf-reader.mjs
was being loaded, maybe some module loading logic changed in >= 40-x-y
which are based on Node.js v24.x. In either case, it is best to
align the loading of wasm module required for the tests in light
of changes to how we are registering the trap handlers for the
main process.

The install process spawn was not capturing its own signal variable,
causing the error check to incorrectly reference the build signal
instead. This could lead to:
- Install termination by signal going undetected
- False positive errors when build was killed but install succeeded
This commit ensures the install signal is properly captured and
checked, matching the pattern used for the build process.
`bringToFront` DevTools message is sent when breakpoint is triggered
or inspect is called and Chromium upon this message activates DevTools
via `DevToolsUIBindings::Delegate::ActivateWindow`:
```
void DevToolsWindow::ActivateWindow() {
if (life_stage_ != kLoadCompleted)
return;
\#if BUILDFLAG(IS_ANDROID)
NOTIMPLEMENTED();
\#else
if (is_docked_ && GetInspectedBrowserWindow())
main_web_contents_->Focus();
else if (!is_docked_ && browser_ && !browser_->window()->IsActive())
browser_->window()->Activate();
\#endif
}
```
which implements: `DevToolsUIBindings::Delegate::ActivateWindow`.
Electron also implements this interface in:
`electron::InspectableWebContents`. However it was only setting
a zoom level, therefore this commit extends it with activation
of the DevTools.
Only supported for DevTools manged by `electron::InspectableWebContents`.
Closes: #37388
If either `npm_config_electron_use_remote_checksums` or
`electron_use_remote_checksums` are set as environment variables, then
force Electron to verify with remote checksums instead of embedded ones.
Fixes#48594.

* chore: bump nan to 2.23.0
* Fix C++ flags passed to C compiler in NAN spec runner
Passing C++-specific flags to the C compiler caused failures building native test modules.
NAN uprgaded the version of node-gyp it uses, triggering a new codepath with the C compiler that didn't occur before. In that new branch, the C++ flags present in the CFLAGS environment variable we were passing in caused the C compiler to error out:
```
error: invalid argument '-std=c++20' not allowed with 'C'
```
The fix is to only pass C++-specific flags to the C++ compiler, and not the C compiler. This is done by separating out the CFLAGS and CXXFLAGS environment variables in our nan-spec-runner.js script.
I'm curious to know more about why each of these flags are necessary, but for now this change restores the previous behavior where native test modules could be built successfully.

Since we haven't touched this in a few years, and since there's a

to restore this flag would be pretty large (~750 lines), I'm going
to try just removing the flag from our source to see if the spec

We overriden the `GetPackageJSON` in Node.js to let us read files
straight from the ASAR file instead of disk. The override works by
providing a JS method with the limitation that it should not throw a
runtime error. However, this invariant was accidentally violated by
`asar.splitPath` that sometimes contrary to its' TypeScript definition
returned `false`.
fix: macOS stop overriding private cornerMask API to fix WindowServer GPU load spike
Electron fetched a custom `_cornerMask` for `ElectronNSWindow` to smooth
vibrancy corners. On macOS 15 (Tahoe) that private hook forces the window
shadow to be rendered from a fully transparent surface, causing the
WindowServer GPU load regression. Remove the `cornerMask` property and
the `_cornerMask` override so we stay on Apple’s default shadow path.

Electron embeds Chromium (rendering) and Node.js (backend) to enable desktop apps with web technologies. The parent directory (`../`) is the Chromium source tree.
### Process Model
Electron has two primary process types, mirroring Chromium:
- **Renderer process** (`shell/renderer/` + `lib/renderer/`): Runs web content in BrowserWindows
### Native ↔ JavaScript Bridge
Each API is implemented as a C++/JS pair:
- C++ side: `shell/browser/api/electron_api_{name}.cc/.h` — uses `gin::Wrappable` and `ObjectTemplateBuilder`
- JS side: `lib/browser/api/{name}.ts` — exports the module, registered in `lib/browser/api/module-list.ts`
- Binding: `NODE_LINKED_BINDING_CONTEXT_AWARE(electron_browser_{name}, Initialize)` in C++ and registered in `shell/common/node_bindings.cc`
- Type declaration: `typings/internal-ambient.d.ts` maps `process._linkedBinding('electron_browser_{name}')`
### Patches System
Electron patches upstream dependencies (Chromium, Node.js, V8, etc.) rather than forking them. Patches live in `patches/` organized by target, with `patches/config.json` mapping directories to repos.
This issue has been automatically marked as stale. **If this issue is still affecting you, please leave any comment** (for example, "bump"), and we'll keep it open. If you have any new additional information—in particular, if this is still reproducible in the [latest version of Electron](https://www.electronjs.org/releases/stable) or in the [beta](https://www.electronjs.org/releases/beta)—please include it with your comment!

### Windows
On Windows, you have to install your app into a user's machine before you can
use the `autoUpdater`, so it is recommended that you use
[electron-winstaller][installer-lib] or [Electron Forge's Squirrel.Windows maker][electron-forge-lib] to generate a Windows installer.
On Windows, the `autoUpdater` module automatically selects the appropriate update mechanism
based on how your app is packaged:
* **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)),
the module uses the MSIX updater, which supports direct MSIX file links and JSON update feeds.
***Squirrel.Windows**: For apps installed via traditional installers (created with
[electron-winstaller][installer-lib] or [Electron Forge's Squirrel.Windows maker][electron-forge-lib]),
the module uses Squirrel.Windows for updates.
You don't need to configure which updater to use; Electron automatically detects the packaging
format and uses the appropriate one.
#### Squirrel.Windows
Apps built with Squirrel.Windows will trigger [custom launch events](https://github.com/Squirrel/Squirrel.Windows/blob/51f5e2cb01add79280a53d51e8d0cfa20f8c9f9f/docs/using/custom-squirrel-events-non-cs.md#application-startup-commands)

`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.
### Linux
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`.
`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.

### 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)
`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.
It is possible to circumvent this limitation by capturing system audio with another macOS app like [BlackHole](https://existential.audio/blackhole/) or [Soundflower](https://rogueamoeba.com/freebies/soundflower/) and passing it through a virtual audio input device. This virtual device can then be queried with `navigator.mediaDevices.getUserMedia`.

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.
It moves the `sharedTextureHandle`, `planes`, `modifier` into a unified `handle` property.
See [here](https://www.electronjs.org/docs/latest/api/structures/offscreen-shared-texture) for more details.
See the [OffscreenSharedTexture](./api/structures/offscreen-shared-texture.md) API structure for more details.
Previously, Electron changed the value of `XDG_CURRENT_DESKTOP` internally to `Unity`, and stored the original name of the desktop session
in a separate variable. `XDG_CURRENT_DESKTOP` is no longer overridden and now reflects the actual desktop environment.

## Setting up `@electron/build-tools` (recommended)
[Electron's Build Tools](https://github.com/electron/build-tools) automate much of the setup for compiling Electron from source with different configurations and build targets. If you wish to set up the environment manually, the instructions are listed below.

Due to Electron's dependency on Chromium, prerequisites and dependencies for Electron change over time. [Chromium's documentation on building on Linux](https://chromium.googlesource.com/chromium/src/+/HEAD/docs/linux/build_instructions.md) has up to date information for building Chromium on Linux. This documentation can generally
be followed for building Electron on Linux as well.
On Ubuntu >= 20.04, install the following libraries:
Other distributions may offer similar packages for installation via package
managers such as pacman. Or one can compile from source code.
Additionally, Electron's [Linux dependency installer](https://github.com/electron/build-images/blob/main/tools/install-deps.sh) can be referenced to get the current dependencies that Electron requires in addition to what Chromium installs via [build/install-deps.sh](https://chromium.googlesource.com/chromium/src/+/HEAD/build/install-build-deps.sh).
