A new Spring Web Flow 2.4.4 maintenance release is now available for download or use from Maven and Gradle builds. This release extends compatibility to Hibernate 5.2 and also includes several mainly JSF related fixes.
In this article we continue the series on Reactive Programming, and the focus is less on learning the basic APIs and more on more concrete use cases and writing code that actually does something useful. We will see how Reactive is a useful abstraction for concurrent programming, but also that it has some very low level features that we should learn to treat with respect and caution. If we start to use these features to their full potential we can take control of layers in our application that previously were invisible, hidden by containers, platforms and frameworks.
