Please read here for more details.
• 357: Improve Project Layout and Refactor Controller Package. Note: the PR significantly changed the layout of the project to follow best practices.

• 391: Update default lb-method to be random two least_conn. Note: the default load balancing method is now the power of two choices as it better suits the Ingress Controller use case. Please read the blog post about the method for more details.
• 344: Expose NGINX Plus API/NGINX stub_status on a custom port via the -nginx-status-port command-line argument. Note: For NGINX the stub_status is now exposed on port 8080 at the /stub_status URL by default. Previously, the stub_status was not exposed on any port. The stub_status can be disabled via the -nginx-status flag.
