Hi, Spring fans! Welcome to another installment of This Month in Spring! It’s the week before Thanksgiving and I’ve got some feelings. First: Spring boot 3.4 came out and its amazing! (more on that later). Second: Happy Thanksgiving to those of you who celebrate! This time of year we Americans are meant to take stock in that for which we’re thankful and make no mistake, my friends, I am super grateful for you!
Now then, about that Spring Boot 3.4 release. Remember: Spring projects leave open-source support after a year. So, roughly, when Spring Boot 3.4.0 drops, Spring Boot 3.2.0 and earlier versions won’t be supported anymore. If you want to know where you stand, check the support windows on the various projects’ pages.
- Spring Framework 6.2.0 available now! This foundational piece kicks off our release cycle for the season. Remember: we do new releases of Spring Framework and Spring Boot every six months! Spring Framework 6.2 brings new baseline dependencies, removed APIs, tweaked
Prioritybehavior in the core container, deeper generic type matching,@Fallbackbeans, SpEL updates, smarter resource loading in web applications, messaging updates for JMS message listener containers, improved testing support, support for escaping property placeholder expressions, a new background initialization mode for individual beans, enhanced indexing support in SpEL, bean overriding in tests with@TestBean,@MockitoBean, and@MockitoSpyBean, AssertJ with MockMvc, dynamic property registration in a test’sApplicationContext, constructor data binding to lists, maps, and arrays, data binding from headers, fragment rendering, content negotiation for@ExceptionHandlermethods, URL parsing,UrlHandlerFilterfor trailing slash match, easier reflection hint registration for native applications, and much more! It’s jam-packed with good stuff so check it out! - Spring Security 6.4.0 has gone GA!
