Hi @bryghtlabs-richard, Thanks for reporting this issue. I have raised the PR to update the nghttp2 module to version 1.68.0. But we are not removing any older API for backward compatibility.

Please feel free to ask any query.

Hi @hrushikesh430 , thank you for looking into this.

I think updating nghttp2 module is a good idea, though it is separate from this request.

This request is about sh2lib, the example wrapper from Espressif showing how to use nghttp2 on ESP chips. What I mean is that the sh2lib code uses deprecated nghttp2 functions, like this one should be updated: https://github.com/espressif/idf-extra-components/blob/master/sh2lib/sh2lib.c#L406
