Existing some place where i can see the news url? my preocupation with this in future some vhost in my conf not renew certificates with mod_md because this url is changed.
We generally announce the terms-of-service change in the API Announcements forum category. Here is the post about the change on Nov 15th.
The subscriber agreement URL is only checked at the time of creating a registration. If you already have a certificate/registration it shouldn't affect renewals.
@cpu Having a set of static links to the latest versions of those would be handy for automated retrieval purposes. While we’re at it, plain text copies of all of these documents would be nice.
The ACME protocol already implements two separate future-proof ways to learn the current agreement URL at runtime (from the directory meta element and as part of the new-reg flow). It's an unfortunate design decision that mod_md chose to require users to specify the URL manually.
We also maintain a URL endpoint https://acme-v01.api.letsencrypt.org/terms that returns a Location header to the current agreement URL. This is Let's Encrypt specific and the ACME protocol approaches I mention above are preferable because they will work across other ACME CAs.
We don't want to have a generic "https://community.letsencrypt.org/licenses" URL that works for registration because there is a legal requirement that subscribers indicate the specific subscriber agreement they have read, understood, and agreed to.
