I am wondering if anyone can inform me about the version of certbot that introduced support for Asynchronous Order Finalization. We have several customers who are still using older legacy CentOS servers. I am concerned that there may be a surge in support requests when the next brownout or rollout of this breaking change occurs.
I'm looking at the code for v0.31.0 (a common version on older distros) and it polls during finalization. I haven't checked earlier versions but they probably do it too.
Thank you two very much for the fast reply. So I guess the older Hosts with old Certbot Versions shouldn't be affected by Asynchronous Order Finalization
Certbot has supported correctly polling orders while waiting for finalization to complete since the very first version that supported ACMEv2 Orders at all:
