Jackson 2.21.4 and Logback 1.5.33 landed across spring-amqp and spring-pulsar overnight, while spring-ai ships ChatClient refinements and restores observability for Anthropic models.

The dependency wave is predictable and low-risk: Jackson 2.21.4 [1] [6] and Jackson 3.1.4 [2] are now pinned in spring-amqp and spring-pulsar, paired with Logback 1.5.33 [3] [5] which registers properties file URLs to the ConfigurationWatchList for better file monitoring. Spring-pulsar also bumped spring-release-actions to 0.0.5 [4], a development-only tooling update. The real momentum is in spring-ai: ChatClient docs got overhauled with clarified multi-client patterns and new integration tests [7], while ToolExecutionEligibilityPredicate deprecation was cleaned up across all model implementations [8]. The Anthropic chat model regained HTTP-layer observability [9] by swapping to anthropic-java-core and supplying a custom OkHttp client with Micrometer instrumentation. A new EntityParamSpec fluent API landed [10], letting developers toggle provider-native structured output and schema validation per call. Spring-integration tightened deserialization to use DefaultDeserializer.getClassLoader() instead of reflection [11], and bumped to Spring 7.0.8-SNAPSHOT [12].

Action items

→ Upgrade spring-amqp and spring-pulsar to pick up Jackson 2.21.4 and Logback 1.5.33 in your next build cycle spring-projects/spring-amqp [plan]
→ Review spring-ai ChatClient docs if you're managing multiple models or client instances spring-projects/spring-ai [monitor]
→ Test spring-integration changes against your deserialization pipelines before next release spring-projects/spring-integration [plan]
