Even though I'm an "insider", I'm not necessarily in the loop on everything that's going on, so any answer I give will likely be incomplete. But a few things come to mind...most of which are already announced, so they're not really big secrets...just exciting stuff.
* Spring Cloud supports developing applications built around a microservices architecture, enabling microservices to easily discover and consume each other. (There's more to it than that, but as I said, I'm not fully in the loop on that.)
* Spring XD released 2.0.0.M1 recently. Spring XD is a runtime (e.g., server) project that lets you define data flows that pull in data from a "source", optionally transform it, and write it to a "sink". In between, a tap can read the data as it flows through for analysis. It's commonly described as a way to suck in data from various sources into HDFS for big data purposes, but it's also suitable for "small data" integration needs.
* Reactor provides a reactive programming model. I'm less familiar with this project, but becoming very familiar and looking forward to trying it out in a project soon.
And, of course, Spring Boot is (IMO) the most exciting thing that's happened to Spring since...pretty much ever.
