Please add support for the new TLS-ALPN-01 verification standard. According to https://letsencrypt.org/upcoming-features/ that standard was enabled by LetsEncyrpt on July 12th, 2018. Details on the standard can be found at https://datatracker.ietf.org/doc/draft-ietf-acme-tls-alpn/

Hello. Just received a mail as follow from letsenrypt: TLS-SNI-01 validation is reaching end-of-life and will stop working on February 13th, 2019. You need to update your ACME client to use an alternative validation method (HTTP-01, DNS-01 or TLS-ALPN-01) before this date or your certificate renewals will break and existing certificates will start to expire.

I received the same email. Hopefully I won't have to use other methods.

Could you share what happened to close this? What is the resolution?

That feature has been officially deprecated not long after the request was raised - https://letsencrypt.org/docs/challenge-types/, so the update to support it never went ahead.
