Release candidate of Rails 6.1 is ready for testing.

This change allows for an application to optionally log instead of raise when using strict_loading.

This would come in especially handy for deeper nesting past 2 databases when declaring connections.

Host authorization checks can be skipped for specific requests. This allows for health check requests to be permitted for requests with missing or non-matching host headers.

Allow the application or a railtie to load code after the server start (similar to console and tasks blocks).
