Hi, Spring fans! Welcome to another installment of This Week in Spring! This week, I'm in Marrakesh, Morocco, for the epic Devoxx MA talking about all things Spring and cloud with my friends — Google's Ray Tsang and Microsoft's Bruno Borges. Then tomorrow, it's off to Bern and Zurich Switzerland for the local JUGs there. Also, I'm doing a live training on Safari — "Bootiful Kotlin," too.

As usual, we've got a ton of things to cover, so let's get to it!

• Spring Framework 5.1.3, 5.0.11 and 4.3.21 available now
• Spring Cloud Greenwich.M3 is available

• Wondering what affects availability in Pivotal CF? Denise Yu and Josh McKenty explain in this comic
• The Neo4j team is happy to announce the first release of the Neo4j and Apache Kafka integration.
• Spring Data ninja Mark Paluch has just previewed typesafe Kotlin queries for Spring Data MongoDB

• Hat tip to Michael Hunger: "If you're interested in polyglot (R, python, ruby, js, llvm bitcode, java), execution on GraalVM and the AOT capabilities, this three-hour presentation by Oleg and Thomas from Devoxx is really amazing and full of demos.
• Check out Dieter Hubau's slides for a presentation introducing KNative, Istio, Project Riff, and Spring Cloud Function.

Also, we will continue to support folks using hystrix through Spring Cloud Netflix. Ribbon has been in a similar state for more than two years and we have supported it the whole time."
