Older certbot + Asynchronous Order Finalization

Hello everyone,

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.

Thank you in advance for your help.

Best regards,

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.


I think it was introduced in the following commit which landed in v0.22.0:

At least, that commit/PR introduced a deadline of 90 seconds when trying to finalize an order I believe, so that sounds like polling, right?


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 :+1:


Certbot has supported correctly polling orders while waiting for finalization to complete since the very first version that supported ACMEv2 Orders at all:
