Dear Spring community,

It is my pleasure to announce that a feature-complete Spring Framework 4.3 release candidate is available now! This is a perfect opportunity for you to get involved: Please run your regression tests against it, and of course, feel free to try the new features...

Dependency injection refinements:

* @Autowired injection of Map/Collection beans and self references * @Autowired on configuration class constructors (finally!) * No need for declaring @Autowired on a unique non-default constructor * ObjectProvider as a richer variant of an ObjectFactory handle * InjectionPoint/DependencyDescriptor as an injectable argument for @Bean methods

MVC processing refinements:

* Default processing of OPTIONS, HEAD, Allow and If-Unmodified-Since * Support for custom HTTP Vary configuration and HTTP Range on custom resources * Precomposed @GetMapping, @PostMapping, @RequestScope, @SessionScope etc * @RequestAttribute and @SessionAttribute as handler method arguments * Full support for Jackson 2.7's new type resolution algorithm

Various infrastructural refinements across the framework:

* Wider support for composed annotations and for placeholders/expressions in attributes * Richer programmatic metadata in core container exceptions * Component scanning in manifest-defined classpath entries * A background initialization option for bootstrapping JPA / Hibernate * A 'sync' flag on @Cacheable and support for the Caffeine cache provider

We are working towards an RC2 with some remaining fine-tuning and performance improvements in the meantime, preparing for 4.3's general availability on June 1st!

Cheers, Juergen

We are pleased to announce the second milestone of Spring AMQP 1.6 is available.

Additions since the first milestone include:

• The caching connection factory now exposes cache statistics

• @RabbitListener methods now communicate type information to the message converter for inbound messages. This means, for example, the Jackson2JsonMessageConverter no longer needs a custom class mapper when a message without type information in the headers is received (e.g. from a sender that is not a Spring AMQP app). Instead, the @RabbitListener method parameter type is used in the conversion. In addition, the Method and bean are also made available via message properties to custom converters.
