Dear Spring community, I’m pleased to announce that Spring Framework 5.0.5 and 4.3.15 are available now, as another pair of refinement releases which are recommended as immediate upgrades for all users. Our 5.0.5 release is the foundation for the upcoming Spring Boot 2.0.1 release later this week, and 4.3.15 will be picked up by Boot 1.5.11 around the same time. Both framework releases come with plenty of bug fixes but also with a wide selection of refinements, wrapping up before we branch towards Spring Framework 5.1 and turn the 5.0.x and 4.3.x lines into low-volume maintenance mode. Our 5.…
Dear Spring community, I’m pleased to announce that Spring Framework 5.0.3 and 4.3.14 are available now, as another pair of refinement releases which are recommended as immediate upgrades for all users. Our 5.0.3 release is the foundation for the upcoming Spring Boot 2.0 RC1 release next week, and 4.3.14 will be picked up by Boot 1.5.10 around the same time. Spring Framework 5.0.3 comes with fresh support for Kotlin 1.2.20, Reactor Core 3.1.3 and JUnit 5.0.3 and has been successfully tested on the latest JDK 10 early-access builds already.
It also includes fixes for a few recent regressions…
It is about time: The official end of of commercial JDK 6 support is coming up soon, with Oracle declaring December 2018 and IBM declaring April 2018 as the end of their extended support. From a Spring perspective, we take the opportunity to deemphasize JDK 6 support on our end. We'll keep tolerating a JDK 6 runtime in the entire Spring Framework 4.3.x line for all further maintenance releases. However, we won't make compromises for JDK 6 anymore, asking you to upgrade to JDK 7+ for fixes that we'd have to work around specifically for JDK 6 on our end. Even for JDK 7, we expect a recent patch…
Dear Spring community, I'm pleased to announce that Spring Framework 5.0.2 and 4.3.13 are available now, as a pair of refinement releases which are recommended as immediate upgrades for all Spring users.
They will also be part of the upcoming Spring Boot 2.0 M7 and 1.5.9 releases, respectively. 5.0.2 comes with significant tightening-up across the framework, including performance improvements and fine-tuned configuration variants. Many of those changes have been backported to 4.3.13 for streamlined consumption in existing applications. Please note: Our Castor XML support is marked as…
Dear Spring community, It is my pleasure to announce that Spring Framework 5.0.1 is available now, as the first maintenance release in our Spring Framework 5.0 line. In addition to addressing various user-reported bugs, we've applied minor refactorings to clean up unintended leftovers from the 5.0 GA release, e.g. for the reactive codec configurers. This release upgrades Reactor to Bismuth SR3, based on Reactor Core 3.1.1, picking up essential fixes in Reactor Netty. Furthermore, AspectJ 1.8.12 brings some welcome performance improvements to Spring AOP's pointcut expression evaluation at…
Dear Spring community, It is my pleasure to announce that, after more than a year of milestones and RCs and almost two years of development overall, Spring Framework 5.0 is finally generally available as 5.0.0.RELEASE from repo.spring.io and Maven Central! This brand-new generation of the framework is ready for 2018 and beyond: with support for JDK 9 and the Java EE 8 API level (e.g. Servlet 4.0), as well as comprehensive integration with Reactor 3.1, JUnit 5, and the Kotlin language. On top of that all, Spring Framework 5 comes with many functional API variants and introduces a dedicated…
Dear Spring community, It is my pleasure to announce that our fourth and last Spring Framework 5.0 release candidate is available now, aligned with Reactor 3.1 RC1 as well as yesterday's JUnit 5.0 GA, and serving as a foundation for the upcoming Spring Boot 2.0 M4! Spring Framework 5.0 RC4 also comes with first-class support for the final version of the Servlet 4.0 API, provides fine-tuned integration with Hibernate Validator 6.0 and is up-to-date with Jackson 2.9.1 and Kotlin 1.1.4. Our dependency baseline is therefore almost complete, with just Reactor 3.1 GA and a few JDK 9 related updates…
Dear Spring community, I'm pleased to announce that the third Spring Framework 5.0 release candidate is available! This release comes with refined nullability declarations (including the field and bean property level), even stronger Kotlin support (with a declarative bean definition DSL and support for default constructor arguments on Kotlin data classes), as well as several API refinements in Spring WebFlux. Furthermore, Spring Framework 5.0 RC3 ships against Reactor 3.1 M3 and JUnit 5.0 M6 and is fully tested against the recent JDK 9 release candidate. With respect to our remaining roadmap…
Dear Spring community, It is my pleasure to announce that our second Spring Framework 5.0 release candidate is available now. This is a major revision of RC1, with refactorings in our new reactive facilities and in our new path pattern parser, as well as code style refinements all over the framework. This release introduces a formal non-null API declaration for all of our packages, with explicitly nullable arguments and return values annotated as such now (instead of just javadoc'ed). Our nullability annotations are compliant with JSR 305 and specifically supported by IntelliJ IDEA and…
Dear Spring community, It is my pleasure to announce that a feature-complete Spring Framework 5.0 release candidate is available now! We are expecting a further release candidate at the end of May and a final release in late June at this point. As a major revision of the core framework, 5.0 RC1 comes with a Java 8+ baseline and many infrastructure refinements: e.g. our own Commons Logging bridge autodetecting Log4j 2, SLF4J, JUL by default; streamlined use of Servlet 3.1+; and early support for JUnit 5.0 M4. Once again, here are the major Spring Framework 5 feature themes: Reactive programming…
