About the API Announcements category

Low-volume announcement list for API changes. Watch this category if you maintain an ACME client for use with Let’s Encrypt, or administer a hosting provider that offers Let’s Encrypt integration.

To receive email notifications of announcements, sign up for a forum account and use the ‘Watch’ feature (circle in upper right of the category page). If you’d prefer not to create an account on this forum, you can also subscribe to the RSS feed, or use an RSS-to-email service like IFTTT or BlogTrottr to get updates.

If you want to hear about outages and maintenances that will affect your service, check out our status.io page, which also lets you subscribe. These updates are higher frequency.

We also provide a public Google Calendar as an alternate view of upcoming API changes. We try to keep it up to date, but if there’s a disagreement between what’s on the calendar and what’s posted in this category, what’s posted in this category is authoritative.

Only Let’s Encrypt staff can post to this category. If you’d like to post follow-up questions, please start a new thread in the Issuance Tech category, or any other appropriate category.
