I cannot tell if 2.9 is really needed or not. But since there was no update from 2.4 to 2.6 or 2.8 before moving to 2.9 my gut feeling is that you simply took the latest version you can find upstream.


Your "gut feeling" is incorrect - 2.9 was specifically the first release that had this fix https://github.com/wjakob/nanobind/pull/1124
