+*   **The ability to create an NGINX config including some basic App Protect directives will be removed in the upcoming `0.6.0` release at some stage after June 2021.** Please instead use the [NGINX config role](https://github.com/nginxinc/ansible-role-nginx-config) for this (and much more) functionality. This will include the removal of the following variables: `nginx_app_protect_conf_template_enable`, `nginx_app_protect_conf_template`, `nginx_app_protect_demo_workload_protocol`, `nginx_app_protect_demo_workload_host`, `nginx_app_protect_log_policy_syslog_target`, `nginx_app_protect_log_policy_target`.

+*   **The ability to dynamically create App Protect security and log policies via Jinja2 templates will be removed in the `0.6.0` release at some stage after June 2021 due to relative inflexibility.** The `nginx_app_protect_security_policy_file_enable`, `nginx_app_protect_security_policy_file_*`, `nginx_app_protect_log_policy_file_enable` and `nginx_app_protect_log_policy_file_*` variables should be used instead of the following variables which are to be removed: `nginx_app_protect_security_policy_template_enable`, `nginx_app_protect_security_policy_template`, `nginx_app_protect_security_policy_enforcement_mode`, `nginx_app_protect_log_policy_template_enable`, `nginx_app_protect_log_policy_template`, `nginx_app_protect_log_policy_filter_request_type`.
