Comparing v42.2.0 -> v42.4.0 | Electron Releases

42.3.0

- Added session support to net module requests from utility process. #51698

42.4.0

- Fixed an issue where the "Toggle Developer Tools" menu item failed to function correctly with BaseWindow. #51903 ^{(Also in 41, 43)}
- Fixed sandboxed preload scripts running a stale cached version after the script was modified without its file size changing. #51933 ^{(Also in 43)}
- Fixed the context menu in a detached DevTools window focusing the inspected page's window instead of the DevTools window. #51864 ^{(Also in 43)}
42.3.3
- Fixed a crash when calling node:wasi functions with fast API calls enabled. #51867
- Improved external resize band positioning and scaling for frameless windows on Windows. #51561 ^{(Also in 41, 43)}
42.3.1
