Let’s Encrypt is ending support for v1 of their ACME protocol (the thing that actually issues/renews certificates.

Full details: [https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430](https://community.letsencrypt.org/t/end-of-life-plan-for-acmev1/88430)

Key dates:

**November of 2019** : LE will stop allowing new account registrations through our ACMEv1 API endpoint. Existing accounts will continue to function normally.

**June of 2020** : LE will stop allowing new domains to validate via ACMEv1.

**June of 2021** : LE will entirely disable ACMEv1 as a viable way to get a Let’s Encrypt certificate.

First, the good news. Trellis [v1.2.0](https://github.com/roots/trellis/releases/tag/1.2.0) was just released and it includes ACMEv2 support which was added in this PR: [https://github.com/roots/trellis/pull/1114](https://github.com/roots/trellis/pull/1114)

**Existing Trellis sites should continue work for renewing certificates until June 2021**. This is because if you’ve provisioned prior to Nov 2019, your account will already exist.

However, you should try and upgrade to Trellis [v1.2.0](https://github.com/roots/trellis/releases/tag/1.2.0) as soon as possible to avoid any potential issues renewing your certificates. If you don’t want to upgrade and just want the ACMEv2 support changes, you can [apply the patch](https://github.com/roots/trellis/issues/1113#issuecomment-540964639) only.

Hopefully this transition is smooth :smile:

Please let us know if there’s any issues with ACMEv2 in Trellis.
