v5.1.0

Compatibility release for Spring Boot 4.1 / Spring AMQP 4.1.

Highlights

• Raises the baseline from Spring Boot 4.0.6 → 4.1.0 (Spring Framework 7.0.7 → 7.0.8)
• Fixes a context-load failure on Boot 4.1 caused by the relocation of Spring AMQP's ConditionalRejectingErrorHandler (#112)

Fixed

• AMQP autoconfig on Spring Boot 4.1 — Spring AMQP 4.1 moved ConditionalRejectingErrorHandler and FatalExceptionStrategy from org.springframework.amqp.rabbit.listener to org.springframework.amqp.listener, and the old nested DefaultExceptionStrategy no longer resolves. spring-core built against the old coordinates threw NoClassDefFoundError at context load. Imports now target the new package. (#112)
• FieldNameResolver — migrated off the hibernate-validator internal NodeImpl / PathImpl / ConstraintViolationImpl types (removed in hibernate-validator 9.1.0, pulled in by Boot 4.1.0) to the public jakarta.validation.Path / Path.Node API. Behavior is unchanged.

Breaking Changes

• Requires Spring Boot 4.1+. The relocated Spring AMQP package (org.springframework.amqp.listener) does not exist in Spring AMQP 4.0.x, so this release no longer supports Spring Boot 4.0.x. Applications on Boot 4.0.x must stay on spring-core 5.0.0 or upgrade Boot to 4.1.

Dependency Upgrades

Dependency	v5.0.0	v5.1.0
Spring Boot	4.0.6	4.1.0
Spring Framework	7.0.7	7.0.8
Spring AMQP	4.0.x	4.1.0

---

Upgrade note: If your application overrides the AMQP error handler and imports ConditionalRejectingErrorHandler or FatalExceptionStrategy directly, update those imports from org.springframework.amqp.rabbit.listener to org.springframework.amqp.listener.

v5.0.0

v5.0.0

Major release upgrading to Spring Boot 4, Spring Framework 7, and Jackson 3.

Highlights

• Spring Boot 3.5.0 → 4 / Spring Framework 6.2.7 → 7
• Jackson 2.x → 3.x (tools.jackson package) as primary, with Jackson 2.x retained for Retrofit compatibility
• OkHttp 4.x → 5.x, Tomcat 10.x → 11.x, Testcontainers 1.x → 2.x
• Java module name (ee.bitweb.core) added to JAR manifest
• CI now tests on Java 17, 21, and 25

Breaking Changes

• Jackson 3 package rename: All internal Jackson usage moved from com.fasterxml.jackson to tools.jackson. Applications directly referencing library Jackson types must update imports.
• InvalidFormatValidationException now extends RuntimeException instead of InvalidFormatException
• MDCTaskDecorator removed — use BasicMDCTaskDecorator or SecurityAwareMDCTaskDecorator
• TrimmedStringDeserializer.addToObjectMapper() removed — use createModule() instead
• persistenceException log-level property removed — use entityNotFoundException and conflictException separately
• AMQP: Jackson2JsonMessageConverter replaced by JacksonJsonMessageConverter (Jackson 3)
• Actuator/Security import paths changed (Spring Boot 4 package reorganization)
• Test: AutoConfigureMockMvc moved to org.springframework.boot.webmvc.test.autoconfigure
• ObjectMapper config refactored: Now uses JsonMapperBuilderCustomizer for Jackson 3 and a nested customizer for Jackson 2

New

• Jackson2TrimmedStringDeserializer — Jackson 2 string trimming for Retrofit compatibility
• StringUtil.trim() utility method
• Dual Jackson auto-configuration (Jackson 2 + Jackson 3 configured identically)

Removed

• MDCTaskDecorator (deprecated since 3.3.0)
• persistenceException log-level property (deprecated since 3.1.0)
• OWASP dependency-check Gradle plugin
• Spring version matrix CI workflow
