Welcome to another installment of This Week in Spring! This week, I'm in Barcelona, Spain for the Spring I/O conference.

• Spring Social lead Craig Walls just announced the release of Spring Social Facebook 2.0.1, the first maintenance release in the Spring Social Facebook 2.0 line.
• the good Dr. Syer just published a blog on different ways to bind services in Cloud Foundry
• Spring Security lead Rob Winch just released Spring Security 4.0.1, the first maintenance release in the Spring Security 4.0 line
• This Week's SpringOne2GX Replays are out! Marius Bogoevici shows us how to Build highly modular and testable business systems with Spring Integration, Brian Cavalier talks about Efficient Client-Server Communication with Differential Synchronization and JSON Patch and Topher Bullock and Will Tran review Server-side JavaScript with Nashorn and Spring.
• Were you at JAX London last week? No? Then you missed Domain Driven Design author Eric Evan's talk on bounded contexts with microservices. Check it out!
• Zurelsoft's Sanjay Shah put together a decent, high-level pitch for Spring Boot
• Eberhard Wolff's just perfectly expressed the inertia behind monolithic applications: "Monolithic gravity: A large system will attract new features and changes. In the process it will become larger and eventually collapse."
• My pal Geertjan, who works on Oracle's Netbeans platform, just introduced a very cool contribution from Aggelos Karalias that integrates autocompletion support for Spring Boot's metadata about configuration properties. This support is similar to what's available in the latest STS and IntelliJ IDEA 14.1 releases. Very cool!
• InfoQ's just published a nice post on Spring Security 4.
• Apache Geode (the core of Pivotal's Gemfire distributed datagrid technology) has just passed a vote to be an incubator project in the Apache Software Foundation! Congratulations!
• Our pal David Welch just shared a JDBC-backed MetricRepository that looks mighty useful! Check it out!
