 # Changelog
 
+## 0.2.0 (August 27, 2020)
+
+BREAKING CHANGES:
+
+*   The repository names in Debian and RedHat based distros have slightly changed. You may run into some duplication issues when running the role on a preexisting target that already has had NGINX installed using the role. To fix this, manually remove the old repository source.
+
+ENHANCEMENTS:
+
+*   Update Ansible to `2.9.12` and Ansible Lint to `4.3.2`.
+*   Explicitly define `mode` in relevant tasks.
+*   Explicitly define the `nginx-unit` `apt_repository` and `yum_repository` filename in Debian and RedHat based distros.
+
+FEATURES:
+
+*   TravisCI now always uses the latest version of Docker.
+
 ## 0.1.0 (August 19, 2020)
