+## 0.18.2 - 2017-09-20
+
+### Fixed
+
+* An issue where Certbot's ACME module would raise an AttributeError trying to
+  create self-signed certificates when used with pyOpenSSL 17.3.0 has been
+  resolved. For Certbot users with this version of pyOpenSSL, this caused
+  Certbot to crash when performing a TLS SNI challenge or when the Nginx plugin
+  tried to create an SSL server block.
+
+More details about these changes can be found on our GitHub repo:
