One of the nice things about working for Pivotal is that they have a great agile development division called Pivotal Labs. The teams within Labs are big proponents of Lean and XP software methodologies such as pair programming and test-driven development. Their love of testing has had a particular impact on Spring Boot 1.4 as we've started to get great feedback on things that could be improved. This blog post highlights some of the new testing features that have just landed in the latest M2 release.

Spring Boot 1.3.2 has been released and is available now from repo.spring.io and Maven Central.

This maintenance release includes a number of fixes and 3rd party dependency updates.

If you are upgrading from 1.3.1 there is one potentially breaking change; we now only search for messages.properties (and not messages*.properties) to enable auto-configuration of a message source. If you previously had a message file of the form messages_en.properties and you didn't include a default messages.properties file, you will now need to add one.

Over the Thanksgiving weekend a 2014 article called "Why I hate Spring" by Sam Atkinson started doing the rounds on Twitter. It's always interesting to listen to criticisms to see what we can do to improve Spring, much of Spring Boot was born out of listening to people talk about the problems that they faced with the framework.
