Has this authorization validity period changed recently from 10 months to 1 day? Am experiencing a few issues due to this on my client implementation. Please confirm this and if it is related to following the new ACME draft-04. Is there a way to receive notifications on such changes so that we may modify our independent implementations/integrations of the LE Client, when needed? Often times, we’re only able to identify a breakage on our side due to a modification in the LE server implementation, after the fact. Even if you don’t consider the change to be backwards-incompatible, it may still break something depending on how we’ve integrated the client.
And since ACME is still evolving, we can be sure to expect the server-side to have lots of implementation changes. I would greatly appreciate it if there was an easy way to receive notifications or somehow follow each change made on the LetsEncrypt server side, in order to avoid such situations in the future.
