A series of major releases and updates in the Java ecosystem were announced this week, reflecting continued development activity across enterprise frameworks, build tools, and data processing libraries. The roundup for May 18, 2026, includes general availability releases of WildFly 40, Micronaut 5.0, Maven Embedded GlassFish Plugin 8.0, and Apache Fory 1.0, along with the May 2026 edition of Open Liberty and incremental point releases for Gatherers4j, Apache, and Kafka. The seventh milestone of Spring AI 2.0 was also made available.<\/p>\n
WildFly 40, the latest version of the open source application server developed by Red Hat, is now generally available. This release introduces updates to the server’s management console and underlying Jakarta EE components. The new version aims to improve runtime efficiency and developer experience, though the maintainers have not yet published detailed changelogs or migration guides for this specific release.<\/p>\n
Micronaut 5.0, a major update to the JVM based framework for building modular, easily testable microservices and serverless applications, has been released. This version includes enhancements to compile time dependency injection, AOT compilation, and support for GraalVM native images. The release notes highlight improved integration with observability tools and updated module documentation.<\/p>\n
Apache Fory 1.0 reached general availability, marking the first stable release of this new project. Fory is designed to simplify the building of event driven applications on the JVM, although its detailed feature set and intended use cases have not been fully documented in official channels. Separately, the Maven Embedded GlassFish Plugin 8.0 is now available, providing a Maven plugin to run embedded GlassFish servers for testing and development purposes. This version aligns with recent GlassFish 8.x releases.<\/p>\n
The May 2026 edition of Open Liberty, IBM’s lightweight Java runtime, is now available. This update includes fixes for reported issues, as well as support for newer versions of MicroProfile and Jakarta EE specifications. The release notes indicate incremental improvements to startup time and configuration processing.<\/p>\n
Point releases were issued for Gatherers4j, Apache, and Kafka. Gatherers4j, a library for constructing custom stream gatherers, received a maintenance update. Apache, the umbrella project for many open source tools, saw updates to several of its components. Apache Kafka, the distributed event streaming platform, was updated to address specific bugs and performance bottlenecks reported by users.<\/p>\n
Spring AI 2.0 milestone 7 has been released, continuing the evolution of the Spring ecosystem’s artificial intelligence integration framework. This milestone introduces refinements to the API vector store support, and integration with additional large language model providers. The Spring team has indicated that the final 2.0 release is expected later this year, with further milestones planned.<\/p>\n
Developers and enterprises relying on these technologies are advised to review the official release notes and migration guides for each project before upgrading. The next Java roundup is scheduled for May 25, 2026, which will likely include additional updates and the release of further patch versions for the projects mentioned this week.<\/p>\n","protected":false},"excerpt":{"rendered":"
