  1. # Release Notes for v43.7.0
  3. ## Features
  5. * Added `initiatorOrigin` to webRequest and protocol handler requests, `DownloadItem.getInitiatorOrigin()`, and a trailing `frame` argument to the `will-download` and `preconnect` session events. [#53704](https://github.com/electron/electron/pull/53704) <sup>(Also in [44](https://github.com/electron/electron/pull/53703), [45](https://github.com/electron/electron/pull/53700))</sup>
  6. * Added the `ELECTRON_DEBUG_DRAGGABLE_REGIONS` environment variable, which visualizes and logs draggable regions in unpackaged apps to help debug custom title bars. [#53633](https://github.com/electron/electron/pull/53633) <sup>(Also in [44](https://github.com/electron/electron/pull/53627), [45](https://github.com/electron/electron/pull/53626))</sup>
  7. ## Fixes
  9. * File System Access permission requests and the `file-system-access-restricted` event are scoped to the requesting document, grants are reset when the origin's last page closes, and write access works in in-memory sessions. [#53694](https://github.com/electron/electron/pull/53694) <sup>(Also in [42](https://github.com/electron/electron/pull/53695), [44](https://github.com/electron/electron/pull/53691), [45](https://github.com/electron/electron/pull/53690))</sup>
  10. * Fixed `session.setPermissionCheckHandler` receiving the top-level origin and a null `webContents` for `hid` and `usb` checks made from a subframe. [#53689](https://github.com/electron/electron/pull/53689) <sup>(Also in [42](https://github.com/electron/electron/pull/53736), [44](https://github.com/electron/electron/pull/53688), [45](https://github.com/electron/electron/pull/53679))</sup>
  11. * Fixed `webContents.on()`, `removeListener()` and `removeAllListeners()` throwing "Object has been destroyed" for `console-message` listeners after the WebContents was destroyed. [#53496](https://github.com/electron/electron/pull/53496) <sup>(Also in [42](https://github.com/electron/electron/pull/53497), [44](https://github.com/electron/electron/pull/53494), [45](https://github.com/electron/electron/pull/53495))</sup>
  12. * Fixed a crash on Linux when `process.env` was written while another thread was reading the environment, and a memory leak when a worker thread exits. [#53510](https://github.com/electron/electron/pull/53510) <sup>(Also in [42](https://github.com/electron/electron/pull/53511), [44](https://github.com/electron/electron/pull/53509), [45](https://github.com/electron/electron/pull/53508))</sup>
  13. * Fixed a possible crash on Windows when a file dialog was shown for a window that was being closed at the same time. [#53584](https://github.com/electron/electron/pull/53584) <sup>(Also in [42](https://github.com/electron/electron/pull/53585), [44](https://github.com/electron/electron/pull/53583), [45](https://github.com/electron/electron/pull/53586))</sup>
  14. * Fixed a renderer crash when the main process sent IPC to, or a page navigated, a same-process `window.open()` child whose `contextIsolation` differed from its opener's. [#53540](https://github.com/electron/electron/pull/53540) <sup>(Also in [42](https://github.com/electron/electron/pull/53541), [44](https://github.com/electron/electron/pull/53539), [45](https://github.com/electron/electron/pull/53538))</sup>
  15. * Fixed an issue where the browser-side check that blocks drag and drop between cross-site frames of the same page was disabled. [#53750](https://github.com/electron/electron/pull/53750) <sup>(Also in [44](https://github.com/electron/electron/pull/53749), [45](https://github.com/electron/electron/pull/53748))</sup>
  16. * Fixed crashes in `setDisplayMediaRequestHandler` when the granted frame had been destroyed or another tab was granted by id. [#53671](https://github.com/electron/electron/pull/53671) <sup>(Also in [42](https://github.com/electron/electron/pull/53674), [44](https://github.com/electron/electron/pull/53672), [45](https://github.com/electron/electron/pull/53673))</sup>
  17. * Fixed several non-functional DevTools integrations: the Security panel's "View certificate" button, Ctrl+wheel zooming inside DevTools, and DevTools keyboard shortcuts (e.g. F8) while the inspected page has focus. [#53631](https://github.com/electron/electron/pull/53631) <sup>(Also in [44](https://github.com/electron/electron/pull/53630), [45](https://github.com/electron/electron/pull/53471))</sup>
  18. * Internal `<webview>`, `window.close()` and `executeJavaScript` reply IPCs are validated against the sending frame. [#53726](https://github.com/electron/electron/pull/53726) <sup>(Also in [42](https://github.com/electron/electron/pull/53727), [44](https://github.com/electron/electron/pull/53723), [45](https://github.com/electron/electron/pull/53724))</sup>
  19. * `<webview>` without `allowpopups` also blocks links opened into a new window by modifier-click, and such windows navigate as the clicking document rather than as a browser-initiated load. [#53718](https://github.com/electron/electron/pull/53718) <sup>(Also in [42](https://github.com/electron/electron/pull/53719), [44](https://github.com/electron/electron/pull/53721), [45](https://github.com/electron/electron/pull/53717))</sup>
  20. * `getUserMedia` with `chromeMediaSource: 'desktop'` no longer accepts WebContents source ids; use `chromeMediaSource: 'tab'` with `webContents.getMediaSourceId()` or `setDisplayMediaRequestHandler` to capture a WebContents. [#53707](https://github.com/electron/electron/pull/53707) <sup>(Also in [42](https://github.com/electron/electron/pull/53710), [44](https://github.com/electron/electron/pull/53709), [45](https://github.com/electron/electron/pull/53708))</sup>
  21. * `nodeIntegrationInWorker` now applies only to workers created by frames that themselves have Node integration; enable `nodeIntegrationInSubFrames` to keep Node in workers created by subframes. [#53712](https://github.com/electron/electron/pull/53712) <sup>(Also in [42](https://github.com/electron/electron/pull/53713), [44](https://github.com/electron/electron/pull/53711), [45](https://github.com/electron/electron/pull/53706))</sup>
  22. * `openExternal` permission requests started by a frame that has since gone away are attributed to that frame's origin rather than to the navigating page. [#53698](https://github.com/electron/electron/pull/53698) <sup>(Also in [42](https://github.com/electron/electron/pull/53697), [44](https://github.com/electron/electron/pull/53699), [45](https://github.com/electron/electron/pull/53696))</sup>
  23. * `pointerLock` and `keyboardLock` permission requests now report the requesting frame, and `execCommand('paste')` requires user activation in the frame that calls it. [#53701](https://github.com/electron/electron/pull/53701) <sup>(Also in [42](https://github.com/electron/electron/pull/53702), [44](https://github.com/electron/electron/pull/53693), [45](https://github.com/electron/electron/pull/53692))</sup>

  27. * Fixed a renderer crash that could occur when printing from an iframe. [#53761](https://github.com/electron/electron/pull/53761) <sup>(Also in [44](https://github.com/electron/electron/pull/53762), [45](https://github.com/electron/electron/pull/53763))</sup>
  28. * Fixed the app becoming unresponsive when a page has a very large number of `app-region` draggable elements. [#53632](https://github.com/electron/electron/pull/53632) <sup>(Also in [44](https://github.com/electron/electron/pull/53597), [45](https://github.com/electron/electron/pull/53596))</sup>
