  1. # Release Notes for v43.5.0
  3. ## Fixes
  5. * Fixed DevTools device metrics overrides persisting indefinitely when a remote debugging client disconnected without clearing them. [#52946](https://github.com/electron/electron/pull/52946) <sup>(Also in [42](https://github.com/electron/electron/pull/53133), [44](https://github.com/electron/electron/pull/52930))</sup>
  6. * Fixed `BrowserWindow.unmaximize()` and `restore()` having no effect on Wayland when the window was maximized immediately after creation. [#53125](https://github.com/electron/electron/pull/53125) <sup>(Also in [42](https://github.com/electron/electron/pull/53126), [44](https://github.com/electron/electron/pull/53124))</sup>
  7. * Fixed `Uncaught illegal access` errors and possible renderer crashes after closing a same-process child window or removing an iframe with `nodeIntegrationInSubFrames` enabled. [#53041](https://github.com/electron/electron/pull/53041) <sup>(Also in [42](https://github.com/electron/electron/pull/53042), [44](https://github.com/electron/electron/pull/53040))</sup>
  8. * Fixed `fs.constants.O_DIRECTORY`, `O_NOFOLLOW` and `O_DIRECT` holding x86 values on Linux arm64 and armv7l, which made opening a directory fail with `EINVAL`, and made `require('trace_events')` behave the same on cross-compiled builds as on native ones. [#53319](https://github.com/electron/electron/pull/53319) <sup>(Also in [42](https://github.com/electron/electron/pull/53318), [44](https://github.com/electron/electron/pull/53320), [45](https://github.com/electron/electron/pull/53321))</sup>
  9. * Fixed `webContents.executeJavaScriptInIsolatedWorld` resolving with `undefined` when `worldId` was not an integer. [#53237](https://github.com/electron/electron/pull/53237) <sup>(Also in [44](https://github.com/electron/electron/pull/53238))</sup>
  10. * Fixed `webContents.print()` honoring `printBackground`, `duplexMode`, and printer default duplex settings. [#53160](https://github.com/electron/electron/pull/53160) <sup>(Also in [42](https://github.com/electron/electron/pull/53158), [44](https://github.com/electron/electron/pull/53159))</sup>

[#53095](https://github.com/electron/electron/pull/53095) <sup>(Also in [42](https://github.com/electron/electron/pull/53094), [44](https://github.com/electron/electron/pull/53096))</sup>
