+
+### Breaking Changes
+
+### Deprecated: `NativeImage.getBitmap()`
+
+The `NativeImage.getBitmap()` function is now deprecated and documented as an alias for `NativeImage.toBitmap()`.
+The two functions both return a newly-allocated copy of the bitmap and are functionally equivalent.
+
+### Deprecated: Extension methods and events on `session`
+
+`session.loadExtension`, `session.removeExtension`, `session.getExtension`,
+`session.getAllExtensions`, and the events `extension-loaded`,
+`extension-unloaded`, and `extension-ready` have all moved to the new
+[`Extensions` object](https://www.electronjs.org/docs/latest/api/extensions-api)
+accessible via the `session.extensions` instance property.
+
+### Removed: `quota` type `syncable` in `session.clearStorageData(options)`
+
+When calling `session.clearStorageData(options)`, the `options.quota` type
+`syncable` is no longer supported because it has been
+[removed](https://chromium-review.googlesource.com/c/chromium/src/+/6309405)
+from upstream Chromium.
+
+### Deprecated: `quota` property in `session.clearStorageData(options)`
+
+When calling `Session.clearStorageData(options)`, the `options.quota`
+property is deprecated. Since the `syncable` type was removed, there
+is only type left -- `'temporary'` -- so specifying it is unnecessary.
+
+### Behavior Changed: `process.exit()` kills utility process synchronously
+
+Calling `process.exit()` in a utility process will now kill the utility process synchronously.
+This brings the behavior of `process.exit()` in line with Node.js behavior.
+
+Please refer to the
+[Node.js docs](https://nodejs.org/docs/latest-v22.x/api/process.html#processexitcode) and
+[PR #45690](https://github.com/electron/electron/pull/45690) to understand the potential
+implications of that, e.g., when calling `console.log()` before `process.exit()`.
+
+### Behavior Changed: `app.commandLine`
+
+`app.commandLine` will convert uppercases switches and arguments to lowercase.
+
+`app.commandLine` was only meant to handle Chromium switches (which aren't case-sensitive) and switches passed via `app.commandLine` will not be passed down to any of the child processes.
+
+If you were using `app.commandLine` to parse app-specific command line arguments, you should do this via `process.argv`.
+
+## End of Support for 34.x.y
+
+Electron 34.x.y has reached end-of-support as per the project's [support policy](https://www.electronjs.org/docs/latest/tutorial/electron-timelines#version-support-policy). Developers and applications are encouraged to upgrade to a newer version of Electron.
