<div dir="ltr"><div>As an old dog in this world, i don't think you should ever take release notes over config tests and further web tests (siege, wrk, ab). Nginx has become such a versatile server starting with web and any proxy , then with openresty and unit etc ...how can you provide proof of an upgrade path. This is work that only you can finish. FWIW, i have only had to change my conf files for my benefit over the 1.14 to 1.17, but if you don't do this yourself, you need to ask yourself why and how you can that is correct for your environment.<br></div><div><br></div><div>Best<br></div><div>Jeff<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Jul 15, 2019 at 8:53 PM Zheng, Qi <<a href="mailto:qi.zheng@intel.com" target="_blank">qi.zheng@intel.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
