-### Values sent over IPC are now serialized with Structured Clone Algorithm
-
-The algorithm used to serialize objects sent over IPC (through
-`ipcRenderer.send`, `ipcRenderer.sendSync`, `WebContents.send` and related
-methods) has been switched from a custom algorithm to V8's built-in [Structured
-Clone Algorithm][SCA], the same algorithm used to serialize messages for
-`postMessage`. This brings about a 2x performance improvement for large
-messages, but also brings some breaking changes in behavior.
-
-- Sending Functions, Promises, WeakMaps, WeakSets, or objects containing any
-  such values, over IPC will now throw an exception, instead of silently
-  converting the functions to `undefined`.
-```js
-// Previously:
-ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
-// => results in { value: 3 } arriving in the main process
-
-// From Electron 8:
-ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
-// => throws Error("() => {} could not be cloned.")
-```
-- `NaN`, `Infinity` and `-Infinity` will now be correctly serialized, instead
-  of being converted to `null`.
-- Objects containing cyclic references will now be correctly serialized,
-  instead of being converted to `null`.
-- `Set`, `Map`, `Error` and `RegExp` values will be correctly serialized,
-  instead of being converted to `{}`.
-- `BigInt` values will be correctly serialized, instead of being converted to
-  `null`.
-- Sparse arrays will be serialized as such, instead of being converted to dense
-  arrays with `null`s.
-- `Date` objects will be transferred as `Date` objects, instead of being
-  converted to their ISO string representation.
-- Typed Arrays (such as `Uint8Array`, `Uint16Array`, `Uint32Array` and so on)
-  will be transferred as such, instead of being converted to Node.js `Buffer`.
-- Node.js `Buffer` objects will be transferred as `Uint8Array`s. You can
-  convert a `Uint8Array` back to a Node.js `Buffer` by wrapping the underlying
-  `ArrayBuffer`:
-```js
-Buffer.from(value.buffer, value.byteOffset, value.byteLength)
-```
-
-Sending any objects that aren't native JS types, such as DOM objects (e.g.
-`Element`, `Location`, `DOMMatrix`), Node.js objects (e.g. `process.env`,
-`Stream`), or Electron objects (e.g. `WebContents`, `BrowserWindow`,
-`WebFrame`) is deprecated. In Electron 8, these objects will be serialized as
-before with a DeprecationWarning message, but starting in Electron 9, sending
-these kinds of objects will throw a 'could not be cloned' error.
-
-[SCA]: https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm
-
-### `<webview>.getWebContents()`
-
-This API is implemented using the `remote` module, which has both performance
-and security implications. Therefore its usage should be explicit.
-
-```js
-// Deprecated
-webview.getWebContents()
-// Replace with
-const { remote } = require('electron')
-remote.webContents.fromId(webview.getWebContentsId())
-```
-
-However, it is recommended to avoid using the `remote` module altogether.
-
-```js
-// main
-const { ipcMain, webContents } = require('electron')
-
-const getGuestForWebContents = function (webContentsId, contents) {
-  const guest = webContents.fromId(webContentsId)
-  if (!guest) {
-    throw new Error(`Invalid webContentsId: ${webContentsId}`)
-  }
-  if (guest.hostWebContents !== contents) {
-    throw new Error(`Access denied to webContents`)
-  }
-  return guest
-}
-
-ipcMain.handle('openDevTools', (event, webContentsId) => {
-  const guest = getGuestForWebContents(webContentsId, event.sender)
-  guest.openDevTools()
-})

-### `webkitdirectory` attribute for `<input type="file"/>`
-
-The `webkitdirectory` property on HTML file inputs allows them to select folders.
-Previous versions of Electron had an incorrect implementation where the `event.target.files`
-of the input returned a `FileList` that returned one `File` corresponding to the selected folder.
-
-As of Electron 7, that `FileList` is now list of all files contained within
-the folder, similarly to Chrome, Firefox, and Edge
-([link to MDN docs](https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/webkitdirectory)).
-
-As an illustration, take a folder with this structure:
-```console
-folder
-├── file1
-├── file2
-└── file3
-```
-
-In Electron <=6, this would return a `FileList` with a `File` object for:
-```console
-path/to/folder
-```
-
-In Electron 7, this now returns a `FileList` with a `File` object for:
-```console
-/path/to/folder/file3
-/path/to/folder/file2
-/path/to/folder/file1
-```
-
-Note that `webkitdirectory` no longer exposes the path to the selected folder.
-If you require the path to the selected folder rather than the folder contents,
-see the `dialog.showOpenDialog` API ([link](https://github.com/electron/electron/blob/master/docs/api/dialog.md#dialogshowopendialogbrowserwindow-options)).

-# Patches in Electron
-
-Electron is built on two major upstream projects: Chromium and Node.js. Each of these projects has several of their own dependencies, too. We try our best to use these dependencies exactly as they are but sometimes we can't achieve our goals without patching those upstream dependencies to fit our use cases.
-
-## Patch justification
-
-Every patch in Electron is a maintenance burden. When upstream code changes, patches can break—sometimes without even a patch conflict or a compilation error. It's an ongoing effort to keep our patch set up-to-date and effective. So we strive to keep our patch count at a minimum. To that end, every patch must describe its reason for existence in its commit message. That reason must be one of the following:
-
-1. The patch is temporary, and is intended to be (or has been) committed upstream or otherwise eventually removed. Include a link to an upstream PR or code review if available, or a procedure for verifying whether the patch is still needed at a later date.
-2. The patch allows the code to compile in the Electron environment, but cannot be upstreamed because it's Electron-specific (e.g. patching out references to Chrome's `Profile`). Include reasoning about why the change cannot be implemented without a patch (e.g. by subclassing or copying the code).
-3. The patch makes Electron-specific changes in functionality which are fundamentally incompatible with upstream.
-
-In general, all the upstream projects we work with are friendly folks and are often happy to accept refactorings that allow the code in question to be compatible with both Electron and the upstream project. (See e.g. [this](https://chromium-review.googlesource.com/c/chromium/src/+/1637040) change in Chromium, which allowed us to remove a patch that did the same thing, or [this](https://github.com/nodejs/node/pull/22110) change in Node, which was a no-op for Node but fixed a bug in Electron.) **We should aim to upstream changes whenever we can, and avoid indefinite-lifetime patches**.
-
-## Patch system
-
-If you find yourself in the unfortunate position of having to make a change which can only be made through patching an upstream project, you'll need to know how to manage patches in Electron.
-
-All patches to upstream projects in Electron are contained in the `patches/` directory. Each subdirectory of `patches/` contains several patch files, along with a `.patches` file which lists the order in which the patches should be applied. Think of these files as making up a series of git commits that are applied on top of the upstream project after we check it out.
-
-```text
-patches
-├── config.json   <-- this describes which patchset directory is applied to what project
-├── chromium
-│   ├── .patches
-│   ├── accelerator.patch
-│   ├── add_contentgpuclient_precreatemessageloop_callback.patch
-│   ⋮
-├── node
-│   ├── .patches
-│   ├── add_openssl_is_boringssl_guard_to_oaep_hash_check.patch
-│   ├── build_add_gn_build_files.patch
-│   ⋮
-⋮
-```
-
-To help manage these patch sets, we provide two tools: `git-import-patches` and `git-export-patches`. `git-import-patches` imports a set of patch files into a git repository by applying each patch in the correct order and creating a commit for each one. `git-export-patches` does the reverse; it exports a series of git commits in a repository into a set of files in a directory and an accompanying `.patches` file.
-
-> Side note: the reason we use a `.patches` file to maintain the order of applied patches, rather than prepending a number like `001-` to each file, is because it reduces conflicts related to patch ordering. It prevents the situation where two PRs both add a patch at the end of the series with the same numbering and end up both getting merged resulting in a duplicate identifier, and it also reduces churn when a patch is added or deleted in the middle of the series.
-
-### Usage
-
-#### Adding a new patch
-```bash session
-$ cd src/third_party/electron_node
-$ vim some/code/file.cc
-$ git commit
-$ ../../electron/script/git-export-patches -o ../../electron/patches/node
-```
-
-> **NOTE**: `git-export-patches` ignores any uncommitted files, so you must create a commit if you want your changes to be exported. The subject line of the commit message will be used to derive the patch file name, and the body of the commit message should include the reason for the patch's existence.
-
-Re-exporting patches will sometimes cause shasums in unrelated patches to change. This is generally harmless and can be ignored (but go ahead and add those changes to your PR, it'll stop them from showing up for other people).
-
-#### Editing an existing patch
-```bash session
-$ cd src/v8
-$ vim some/code/file.cc
-$ git log
-# Find the commit sha of the patch you want to edit.
-$ git commit --fixup [COMMIT_SHA]
-$ git rebase --autosquash -i [COMMIT_SHA]^
-$ ../electron/script/git-export-patches -o ../electron/patches/v8
-```
-
-#### Removing a patch
-```bash session
-$ vim src/electron/patches/node/.patches
-# Delete the line with the name of the patch you want to remove
-$ cd src/third_party/electron_node
-$ git reset --hard refs/patches/upstream-head
-$ ../../electron/script/git-import-patches ../../electron/patches/node
-$ ../../electron/script/git-export-patches -o ../../electron/patches/node
-```
-
-Note that `git-import-patches` will mark the commit that was `HEAD` when it was run as `refs/patches/upstream-head`. This lets you keep track of which commits are from Electron patches (those that come after `refs/patches/upstream-head`) and which commits are in upstream (those before `refs/patches/upstream-head`).
-
-#### Resolving conflicts
-When updating an upstream dependency, patches may fail to apply cleanly. Often, the conflict can be resolved automatically by git with a 3-way merge. You can instruct `git-import-patches` to use the 3-way merge algorithm by passing the `-3` argument:
-
-```bash session
-$ cd src/third_party/electron_node
-# If the patch application failed midway through, you can reset it with:
-$ git am --abort
-# And then retry with 3-way merge:
-$ ../../electron/script/git-import-patches -3 ../../electron/patches/node
-```
-
-If `git-import-patches -3` encounters a merge conflict that it can't resolve automatically, it will pause and allow you to resolve the conflict manually. Once you have resolved the conflict, `git add` the resolved files and continue to apply the rest of the patches by running `git am --continue`.

+# Upgrading Chromium
+
+This is an overview of the steps needed to upgrade Chromium in Electron.
+
+- Upgrade libcc to a new Chromium version
+- Make Electron code compatible with the new libcc
+- Update Electron dependencies (crashpad, NodeJS, etc.) if needed
+- Make internal builds of libcc and electron
+- Update Electron docs if necessary
+
+
+## Upgrade `libcc` to a new Chromium version
+
+1. Get the code and initialize the project:
+  ```sh
+  $ git clone git@github.com:electron/libchromiumcontent.git
+  $ cd libchromiumcontent
+  $ ./script/bootstrap -v
+  ```
+2. Update the Chromium snapshot
+  - Choose a version number from [OmahaProxy](https://omahaproxy.appspot.com/)
+    and update the `VERSION` file with it
+    - This can be done manually by visiting OmahaProxy in a browser, or automatically:
+    - One-liner for the latest stable mac version: `curl -so- https://omahaproxy.appspot.com/mac > VERSION`
+    - One-liner for the latest win64 beta version: `curl -so- https://omahaproxy.appspot.com/all | grep "win64,beta" | awk -F, 'NR==1{print $3}' > VERSION`
+  - run `$ ./script/update`
+    - Brew some tea -- this may run for 30m or more.
+    - It will probably fail applying patches.
+3. Fix `*.patch` files in the `patches/` and `patches-mas/` folders.
+4. (Optional) `script/update` applies patches, but if multiple tries are needed
+   you can manually run the same script that `update` calls:
+   `$ ./script/apply-patches`
+  - There is a second script, `script/patch.py` that may be useful.
+    Read `./script/patch.py -h` for more information.
+5. Run the build when all patches can be applied without errors
+  - `$ ./script/build`
+  - If some patches are no longer compatible with the Chromium code,
+    fix compilation errors.
+6. When the build succeeds, create a `dist` for Electron
+  - `$ ./script/create-dist --no_zip`
+    - It will create a `dist/main` folder in the libcc repo's root.
+      You will need this to build Electron.
+7. (Optional) Update script contents if there are errors resulting from files
+   that were removed or renamed. (`--no_zip` prevents script from create `dist`
+   archives. You don't need them.)
+
+
+## Update Electron's code
+
+1. Get the code:
+  ```sh
+  $ git clone git@github.com:electron/electron.git
+  $ cd electron
+  ```
+2. If you have libcc built on your machine in its own repo,
+   tell Electron to use it:
+  ```sh
+  $ ./script/bootstrap.py -v \
+    --libcc_source_path <libcc_folder>/src \
+    --libcc_shared_library_path <libcc_folder>/shared_library \
+    --libcc_static_library_path <libcc_folder>/static_library
+  ```
+3. If you haven't yet built libcc but it's already supposed to be upgraded
+   to a new Chromium, bootstrap Electron as usual
+   `$ ./script/bootstrap.py -v`
+  - Ensure that libcc submodule (`vendor/libchromiumcontent`) points to the
+    right revision
+
+4. Set `CLANG_REVISION` in `script/update-clang.sh` to match the version
+   Chromium is using.
+  - Located in `electron/libchromiumcontent/src/tools/clang/scripts/update.py`
+
+5. Checkout Chromium if you haven't already:
+  - https://chromium.googlesource.com/chromium/src.git/+/{VERSION}/tools/clang/scripts/update.py
+    - (Replace the `{VERSION}` placeholder in the url above to the Chromium
+      version libcc uses.)
+6. Build Electron.
+  - Try to build Debug version first: `$ ./script/build.py -c D`
+  - You will need it to run tests
+7. Fix compilation and linking errors
+8. Ensure that Release build can be built too
+  - `$ ./script/build.py -c R`
+  - Often the Release build will have different linking errors that you'll
+    need to fix.
+  - Some compilation and linking errors are caused by missing source/object
+    files in the libcc `dist`
+9. Update `./script/create-dist` in the libcc repo, recreate a `dist`, and
+   run Electron bootstrap script once again.
+
+### Tips for fixing compilation errors
+- Fix build config errors first
+- Fix fatal errors first, like missing files and errors related to compiler
+  flags or defines
+- Try to identify complex errors as soon as possible.
+  - Ask for help if you're not sure how to fix them
+- Disable all Electron features, fix the build, then enable them one by one
+- Add more build flags to disable features in build-time.
+
+When a Debug build of Electron succeeds, run the tests:
+`$ npm run test`
+Fix the failing tests.
+
+Follow all the steps above to fix Electron code on all supported platforms.
+
+
+## Updating Crashpad
+
+If there are any compilation errors related to the Crashpad, it probably means
+you need to update the fork to a newer revision. See
+[Upgrading Crashpad](upgrading-crashpad.md)
+for instructions on how to do that.
+
+
+## Updating NodeJS
+
+Upgrade `vendor/node` to the Node release that corresponds to the v8 version
+used in the new Chromium release. See the v8 versions in Node on
+
+See [Upgrading Node](upgrading-node.md)
+for instructions on this.
+
+## Verify ffmpeg support
+
+Electron ships with a version of `ffmpeg` that includes proprietary codecs by
+default. A version without these codecs is built and distributed with each
+release as well. Each Chrome upgrade should verify that switching this version
+is still supported.
+
+You can verify Electron's support for multiple `ffmpeg` builds by loading the
+following page. It should work with the default `ffmpeg` library distributed
+with Electron and not work with the `ffmpeg` library built without proprietary
+codecs.

+          document.querySelector('#outcome').textContent = 'Not using proprietary codecs, video emitted source not supported error event.'
+        } else {

+# Upgrading Crashpad
+
+1. Get the version of crashpad that we're going to use.
+  - `libcc/src/third_party/crashpad/README.chromium` will have a line `Revision:` with a checksum
+    - We need to check out the corresponding branch.
+  - Clone Google's crashpad (https://chromium.googlesource.com/crashpad/crashpad)
+    - `git clone https://chromium.googlesource.com/crashpad/crashpad`
+  - Check out the branch with the revision checksum:
+      - `git checkout <revision checksum>`
+  - Add electron's crashpad fork as a remote
+    - `git remote add electron https://github.com/electron/crashpad`
+  - Check out a new branch for the update
+    - `git checkout -b electron-crashpad-vA.B.C.D`
+    - `A.B.C.D` is the Chromium version found in `libcc/VERSION`
+       and will be something like `62.0.3202.94`
+
+2. Make a checklist of the Electron patches that need to be applied
+  with `git log --oneline`
+    - Or view https://github.com/electron/crashpad/commits/previous-branch-name
+
+3. For each patch:
+  - In `electron-crashpad-vA.B.C.D`, cherry-pick the patch's checksum
+    - `git cherry-pick <checksum>`
+  - Resolve any conflicts
+  - Make sure it builds then add, commit, and push work to electron's crashpad fork
+    - `git push electron electron-crashpad-vA.B.C.D`
+
+4. Update Electron to build the new crashpad:
+  - `cd vendor/crashpad`
+  - `git fetch`
+  - `git checkout electron-crashpad-v62.0.3202.94`
+5. Regenerate Ninja files against both targets
+  - From Electron root's root, run `script/update.py`
+  - `script/build.py -c D --target=crashpad_client`
+  - `script/build.py -c D --target=crashpad_handler`
+  - Both should build with no errors
+6. Push changes to submodule reference
+  - (From electron root) `git add vendor/crashpad`
+  - `git push origin upgrade-to-chromium-62`

-      <div>
-        <div>
-          <p>
-            The <code>Menu</code> and <code>MenuItem</code> modules allow you to
-            customize your application menu. If you don't set any menu, Electron
-            will generate a minimal menu for your app by default.
-          </p>
-
-          <p>
-            If you click the 'View' option in the application menu and then the
-            'App Menu Demo', you'll see an information box displayed.

-            <h2>ProTip</h2>
-            <strong>Know operating system menu differences.</strong>
-            <p>
-              When designing an app for multiple operating systems it's
-              important to be mindful of the ways application menu conventions
-              differ on each operating system.
-            </p>
-            <p>
-              For instance, on Windows, accelerators are set with an
-              <code>&</code>. Naming conventions also vary, like between
-              "Settings" or "Preferences". Below are resources for learning
-              operating system specific standards.

-            A context, or right-click, menu can be created with the
-            <code>Menu</code> and <code>MenuItem</code> modules as well. You can
-            right-click anywhere in this app or click the demo button to see an
-            example context menu.
-          </p>
-
-          <p>
-            In this demo we use the <code>ipcRenderer</code> module to show the
