+===== Changes in swagger-ui
+NOTE: For non-boot applications `springfox-swagger-ui` is no longer automatically enabled by adding the dependency. It needs to be explicitly register
+using a resource handler configurer (`WebFluxConfigurer` or `WebMvcConfigurer`). Here is how it is configured in
+`springfox-boot-starter`
+
+NOTE: swagger-ui location has moved from `http://host/context-path/swagger-ui.html`  to `http://host/context-path/swagger-ui/index.html`
+OR `http://host/context-path/swagger-ui/` for short. This makes it work much better with pulling it as a web jar and turning it off
+using configuration properties if not needed.
