+Due to changes made upstream, both
+[V8](https://chromium-review.googlesource.com/c/v8/v8/+/5587859) and
+[Node.js](https://github.com/nodejs/node/pull/45427) now require C++20 as a
+minimum version. Developers using native node modules should build their
+modules with `--std=c++20` rather than `--std=c++17`. Images using gcc9 or
+lower may need to update to gcc10 in order to compile. See
+[#43555](https://github.com/electron/electron/pull/43555) for more details.
