+# Chrome Extension Support
+
+Electron supports a subset of the [Chrome Extensions
+API][chrome-extensions-api-index], primarily to support DevTools extensions and
+Chromium-internal extensions, but it also happens to support some other
+extension capabilities.
+
+[chrome-extensions-api-index]: https://developer.chrome.com/extensions/api_index
+
+> **Note:** Electron does not support arbitrary Chrome extensions from the
+> store, and it is a **non-goal** of the Electron project to be perfectly
+> compatible with Chrome's implementation of Extensions.
+
+## Loading extensions
+
+Electron only supports loading unpacked extensions (i.e., `.crx` files do not
+work). Extensions are installed per-`session`. To load an extension, call
+[`ses.loadExtension`](session.md#sesloadextensionpath):
+
+```js
+const { session } = require('electron')
+
+session.loadExtension('path/to/unpacked/extension').then(({ id }) => {
+  // ...
+})
+```
+
+Loaded extensions will not be automatically remembered across exits; if you do
+not call `loadExtension` when the app runs, the extension will not be loaded.
+
+See the [`session`](session.md) documentation for more information about
+loading, unloading, and querying active extensions.
+
+## Supported Extensions APIs
+
+We support the following extensions APIs, with some caveats. Other APIs may
+additionally be supported, but support for any APIs not listed here is
+provisional and may be removed.

+> Query and receive events from a sessions active service workers.
+
+Process: [Main](../glossary.md#main-process)
+
+Instances of the `ServiceWorkers` class are accessed by using `serviceWorkers` property of
+a `Session`.
+
+For example:
+
+```javascript
+const { session } = require('electron')
+
+// Get all service workers.
+console.log(session.defaultSession.serviceWorkers.getAllRunning())
+
+// Handle logs and get service worker info
+session.defaultSession.serviceWorkers.on('console-message', (event, messageDetails) => {
+  console.log(
+    'Got service worker message',
+    messageDetails,
+    'from',
+    session.defaultSession.serviceWorkers.getFromVersionID(messageDetails.versionId)
+  )
+})
+```
+
+### Instance Events
+
+The following events are available on instances of `ServiceWorkers`:
+
+#### Event: 'console-message'
+
+Returns:
+
+* `event` Event
+* `messageDetails` Object - Information about the console message
+  * `message` String - The actual console message
+  * `versionId` Number - The version ID of the service worker that sent the log message
+  * `source` String - The type of source for this message.  Can be `javascript`, `xml`, `network`, `console-api`, `storage`, `app-cache`, `rendering`, `security`, `deprecation`, `worker`, `violation`, `intervention`, `recommendation` or `other`.
+  * `level` Number - The log level, from 0 to 3.  In order it matches `verbose`, `info`, `warning` and `error`.
+  * `sourceUrl` String - The URL the message came from
+  * `lineNumber` Number - The line number of the source that triggered this console message
+
+Emitted when a service worker logs something to the console.
+
+### Instance Methods
+
+The following methods are available on instances of `ServiceWorkers`:
+
+#### `serviceWorkers.getAllRunning()`
+
+Returns `Record<Number, ServiceWorkerInfo>` - A [ServiceWorkerInfo](structures/service-worker-info.md) object where the keys are the service worker version ID and the values are the information about that service worker.
+
+#### `serviceWorkers.getFromVersionID(versionId)`
+
+* `versionId` Number

+Returns [`ServiceWorkerInfo`](structures/service-worker-info.md) - Information about this service worker
+
+If the service worker does not exist or is not running this method will throw an exception.

+### Types of Breaking Changes
 
-The `FIXME` string is used in code comments to denote things that should be fixed for future releases. See https://github.com/electron/electron/search?q=fixme
+This document uses the following convention to categorize breaking changes:
+
+- **API Changed:** An API was changed in such a way that code that has not been updated is guaranteed to throw an exception.
+- **Behavior Changed:** The behavior of Electron has changed, but not in such a way that an exception will necessarily be thrown.
+- **Default Changed:** Code depending on the old default may break, not necessarily throwing an exception. The old behavior can be restored by explicitly specifying the value.
+- **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
+- **Removed:** An API or feature was removed, and is no longer supported by Electron.

+// Deprecated in Electron 10
+crashReporter.getCrashesDirectory()
+// Replace with

+
+### Deprecated: `crashReporter` methods in the renderer process
+
+Calling the following `crashReporter` methods from the renderer process is
+deprecated:
+
+- `crashReporter.start`
+- `crashReporter.getLastCrashReport`
+- `crashReporter.getUploadedReports`
+- `crashReporter.getUploadToServer`
+- `crashReporter.setUploadToServer`
+- `crashReporter.getCrashesDirectory`
+
+The only non-deprecated methods remaining in the `crashReporter` module in the
+renderer are `addExtraParameter`, `removeExtraParameter` and `getParameters`.
+
+All above methods remain non-deprecated when called from the main process.
+
+See [#23265](https://github.com/electron/electron/pull/23265) for more details.
+
+### Removed: Browser Window Affinity
+
+The `affinity` option when constructing a new `BrowserWindow` will be removed
+as part of our plan to more closely align with Chromium's process model for security,
+performance and maintainability.
+
+For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
+
+### Default Changed: `enableRemoteModule` defaults to `false`
+
+In Electron 9, using the remote module without explicitly enabling it via the
+`enableRemoteModule` WebPreferences option began emitting a warning. In
+Electron 10, the remote module is now disabled by default. To use the remote
+module, `enableRemoteModule: true` must be specified in WebPreferences:
+
+```js
+const w = new BrowserWindow({
+  webPreferences: {
+    enableRemoteModule: true
+  }
+})
+```
+
+We [recommend moving away from the remote
+module](https://medium.com/@nornagon/electrons-remote-module-considered-harmful-70d69500f31).
 
 ## Planned Breaking API Changes (9.0)
 
-### `<webview>.getWebContents()`
+### Default Changed: Loading non-context-aware native modules in the renderer process is disabled by default
+
+As of Electron 9 we do not allow loading of non-context-aware native modules in
+the renderer process.  This is to improve security, performance and maintainability
+of Electron as a project.
+
+If this impacts you, you can temporarily set `app.allowRendererProcessReuse` to `false`
+to revert to the old behavior.  This flag will only be an option until Electron 11 so
+you should plan to update your native modules to be context aware.
