-## Version support policy
-
-:::info
-
-Beginning in September 2021 (Electron 15), the Electron team
-will temporarily support the latest **four** stable major versions. This
-extended support is intended to help Electron developers transition to
-the [new 8-week release cadence](https://electronjs.org/blog/8-week-cadence),
-and will continue until the release of Electron 19. At that time,
-the Electron team will drop support back to the latest three stable major versions.
-
-:::
-
-The latest three *stable* major versions are supported by the Electron team.
-For example, if the latest release is 6.1.x, then the 5.0.x as well
-as the 4.2.x series are supported. We only support the latest minor release
-for each stable release series. This means that in the case of a security fix,
-6.1.x will receive the fix, but we will not release a new version of 6.0.x.
-
-The latest stable release unilaterally receives all fixes from `main`,
-and the version prior to that receives the vast majority of those fixes
-as time and bandwidth warrants. The oldest supported release line will receive
-only security fixes directly.
-
-### Breaking API changes
-
-When an API is changed or removed in a way that breaks existing functionality, the
-previous functionality will be supported for a minimum of two major versions when
-possible before being removed. For example, if a function takes three arguments,
-and that number is reduced to two in major version 10, the three-argument version would
-continue to work until, at minimum, major version 12. Past the minimum two-version
-threshold, we will attempt to support backwards compatibility beyond two versions
-until the maintainers feel the maintenance burden is too high to continue doing so.
-
-### End-of-life
-
-When a release branch reaches the end of its support cycle, the series
-will be deprecated in NPM and a final end-of-support release will be
-made. This release will add a warning to inform that an unsupported
-version of Electron is in use.
-
-These steps are to help app developers learn when a branch they're
-using becomes unsupported, but without being excessively intrusive
-to end users.
-
-If an application has exceptional circumstances and needs to stay
-on an unsupported series of Electron, developers can silence the
-end-of-support warning by omitting the final release from the app's
-`package.json` `devDependencies`. For example, since the 1-6-x series
-ended with an end-of-support 1.6.18 release, developers could choose
-to stay in the 1-6-x series without warnings with `devDependency` of
-`"electron": 1.6.0 - 1.6.17`.

-### 17. Validate the `sender` of all IPC messages
-
-You should always validate incoming IPC messages `sender` property to ensure you
-aren't performing actions or sending information to untrusted renderers.
-
-#### Why?
-
-All Web Frames can in theory send IPC messages to the main process, including
-iframes and child windows in some scenarios.  If you have an IPC message that returns
-user data to the sender via `event.reply` or performs privileged actions that the renderer
-can't natively, you should ensure you aren't listening to third party web frames.
-
-You should be validating the `sender` of **all** IPC messages by default.
-
-#### How?
-
-```js title='main.js (Main Process)'
-// Bad
-ipcMain.handle('get-secrets', () => {
-  return getSecrets();
-});
-
-// Good
-ipcMain.handle('get-secrets', (e) => {
-  if (!validateSender(e.senderFrame)) return null;
-  return getSecrets();

+
+## Supported Versions
+
+_**Note:** Beginning in September 2021 with Electron 15, the Electron team
+will temporarily support the latest **four** stable major versions. This
+extended support is intended to help Electron developers transition to
+the [new eight week release cadence](https://electronjs.org/blog/8-week-cadence), and will continue until May 2022, with
+the release of Electron 19. At that time, the Electron team will drop support
+back to the latest three stable major versions._
+
+The latest three *stable* major versions are supported by the Electron team.
+For example, if the latest release is 6.1.x, then the 5.0.x as well
+as the 4.2.x series are supported.  We only support the latest minor release
+for each stable release series.  This means that in the case of a security fix
+6.1.x will receive the fix, but we will not release a new version of 6.0.x.
+
+The latest stable release unilaterally receives all fixes from `main`,
+and the version prior to that receives the vast majority of those fixes
+as time and bandwidth warrants. The oldest supported release line will receive
+only security fixes directly.
+
+All supported release lines will accept external pull requests to backport
+fixes previously merged to `main`, though this may be on a case-by-case
+basis for some older supported lines. All contested decisions around release
+line backports will be resolved by the [Releases Working Group](https://github.com/electron/governance/tree/main/wg-releases) as an agenda item at their weekly meeting the week the backport PR is raised.
+
+When an API is changed or removed in a way that breaks existing functionality, the
+previous functionality will be supported for a minimum of two major versions when
+possible before being removed. For example, if a function takes three arguments,
+and that number is reduced to two in major version 10, the three-argument version would
+continue to work until, at minimum, major version 12. Past the minimum two-version
+threshold, we will attempt to support backwards compatibility beyond two versions
+until the maintainers feel the maintenance burden is too high to continue doing so.
+
+### Currently supported versions
+
+* 18.x.y
+* 17.x.y
+* 16.x.y
+* 15.x.y
+
+### End-of-life
+
+When a release branch reaches the end of its support cycle, the series
+will be deprecated in NPM and a final end-of-support release will be
+made. This release will add a warning to inform that an unsupported
+version of Electron is in use.
+
+These steps are to help app developers learn when a branch they're
+using becomes unsupported, but without being excessively intrusive
+to end users.
+
+If an application has exceptional circumstances and needs to stay
+on an unsupported series of Electron, developers can silence the
+end-of-support warning by omitting the final release from the app's
+`package.json` `devDependencies`. For example, since the 1-6-x series
+ended with an end-of-support 1.6.18 release, developers could choose
+to stay in the 1-6-x series without warnings with `devDependency` of
+`"electron": 1.6.0 - 1.6.17`.
+
+## Supported Platforms
+
+Following platforms are supported by Electron:
+
+### macOS
+
+Only 64bit binaries are provided for macOS, and the minimum macOS version
+supported is macOS 10.11 (El Capitan).
+
+Native support for Apple Silicon (`arm64`) devices was added in Electron 11.0.0.
+
+### Windows
+
+Windows 7 and later are supported, older operating systems are not supported
+(and do not work).
+
+Both `ia32` (`x86`) and `x64` (`amd64`) binaries are provided for Windows.
+[Native support for Windows on Arm (`arm64`) devices was added in Electron 6.0.8.](windows-arm.md).
+Running apps packaged with previous versions is possible using the ia32 binary.
+
+### Linux
+
+The prebuilt binaries of Electron are built on Ubuntu 18.04.
+
+Whether the prebuilt binary can run on a distribution depends on whether the
+distribution includes the libraries that Electron is linked to on the building
+platform, so only Ubuntu 18.04 is guaranteed to work, but following platforms
+are also verified to be able to run the prebuilt binaries of Electron:
+
+* Ubuntu 14.04 and newer
+* Fedora 24 and newer
+* Debian 8 and newer

+Subject: Reland "Fix noopener case for user activation consumption"
+
+This is a reland of e9828a82b5c182dc9a7fb0ae7226c35ba1726e7d
+
+The MSAN error is from checking status before err in
+content/renderer/render_view_impl.cc .
+https://ci.chromium.org/ui/p/chromium/builders/ci/Linux%20ChromiumOS%20MSan%20Tests/b8821495655905086193/overview
+
+The fix is to split the check for err and kIgnore into two checks,
+and put the err check before kBlocked.
+
+It is probably possible for the browser to consume user activation
+but then eventually mojo returns an error and the renderer doesn't
+consume activation, but that seems pretty marginal.
+
+Original change's description:
+> Fix noopener case for user activation consumption
+>
+>
+> The flow for user activation consumption in window.open was as follows:
+>
+> Renderer: ask the browser to create a new window
+> Browser: consume transient user activation (in the browser, and via RPC
+> to remote frames only)
+> Browser: return success for opener, return ignore for noopener
+> Renderer: consume transient user activation upon success
+>
+> So in the noopener case, the renderer with the local frame where the
+> window.open originated didn't have its transient user activation
+> consumed.
+>
+>
+> The new behavior is to consume user activation in the calling renderer
+> whenever it is consumed in the browser. We accomplish this by returning
+> a distinct value kBlocked to represent failure before the browser
+> consumes user activation.
+>
+> Bug: 1264543, 1291210

+Subject: FSA: Pass File ownership to worker for async FSARFD file operations
+
+We cannot access the backing file as a member of the
+FileSystemAccessRegularFileDelegate since WrapCrossThreadPersistent
+does NOT cancel the task posted to the worker pool if delegate is
+destroyed. Passing ownership to the worker task ensures the file must
+be alive when used. After the operation, ownership of the file is
+passed back to the delegate.
+
+This pattern was already used for the SetLength operation on old Macs.

patches/chromium/disable_compositor_recycling.patch

@@ -6,10 +6,10 @@ 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.
