----------------------------------------------------------------------- Debian Stable Updates Announcement SUA 173-1 https://www.debian.org debian-release@lists.debian.org Harlan Lieberman-Berg October 27th, 2019 ----------------------------------------------------------------------- Package : python-acme Version : 0.28.0-1~deb9u2 [stretch] Importance : high python-acme is part of an implementation of the ACME protocol, as used by the Let's Encrypt certification authority to issue TLS certificates. The ACME protocol has deprecated support for the use of unauthenticated GET requests in favour of authenticated POST requests. On November 1st, Let's Encrypt's staging ACME v2 endpoint will stop supporting the older protocol, with the production endpoint following at a later point. The staging endpoint is used by applications such as certbot in order to perform tests, including when testing renewals with '--dry-run'. This update moves python-acme to use the newer protocol. If you use python-acme, we strongly recommend that you install this update.
