Spring Framework 5 is here, along with Spring Security 5, Spring Data Kay and Spring Boot 2!

The new Spring WebFlux framework integrates an MVC-like component model for reactive processing as well as functional reactive endpoints. We’ll look at the new Netty-based WebFlux runtime and also discuss the use of reactive programming patterns with existing technologies such as Spring MVC.
