Action required: Let's Encrypt certificate renewals

If you received an email titled “Action required: Let’s Encrypt certificate renewals”, this post is for you.

Our initial email didn’t include domain names - after some feedback, we’re planning to send out a second batch of emails that include domain names [edit 2018-01-28: the second batch of emails is out]. Sorry for the trouble!

In the meantime, we’ve got more detailed documentation specifically for Certbot users to upgrade.
