+## 0.18.0 - 2017-09-06
+
+### Added
+
+* The Nginx plugin now configures Nginx to use 2048-bit Diffie-Hellman
+  parameters. Java 6 clients do not support Diffie-Hellman parameters larger
+  than 1024 bits, so if you need to support these clients you will need to
+  manually modify your Nginx configuration after using the Nginx installer.
+
+### Changed
+
+* certbot-auto now installs Certbot in directories under `/opt/eff.org`. If you
+  had an existing installation from certbot-auto, a symlink is created to the
+  new directory. You can configure certbot-auto to use a different path by
+  setting the environment variable VENV_PATH.
+* The Nginx plugin can now be selected in Certbot's interactive output.
+* Output verbosity of renewal failures when running with `--quiet` has been
+  reduced.
+* The default revocation reason shown in Certbot help output now is a human
+  readable string instead of a numerical code.
+* Plugin selection is now included in normal terminal output.
+
+### Fixed
+
+* A newer version of ConfigArgParse is now installed when using certbot-auto
+  causing values set to false in a Certbot INI configuration file to be handled
+  intuitively. Setting a boolean command line flag to false is equivalent to
+  not including it in the configuration file at all.
+* New naming conventions preventing certbot-auto from installing OS
+  dependencies on Fedora 26 have been resolved.
