I haven't tried with other versions between 1.11.2 (which is the latest version shown in the compatibility section). When we tried to build a package with this included we got:
./modules/echo-nginx-module/src/ngx_http_echo_request_info.c: In function ‘ngx_http_echo_client_request_headers_variable’:

It seems like they changed it to use an ngx_chain_t instead of an array of buffers
https://github.com/openresty/echo-nginx-module/blob/master/src/ngx_http_echo_request_info.c#L180
https://github.com/nginx/nginx/blob/fca26c2e53d46549320a3b23ce0398c5921348dd/src/http/ngx_http_request.h#L312
I think it's probably as straightforward as changing the type based on NGINX version, but I wasn't sure if there was more going on there.
