Along with bug fixes and component upgrades, all three editions deliver: a resolution to a Cross-Site Request Forgery (CSRF) and Server-Side Request Forgery (SSRF) issue in the Admin Console and REST management interface due to unnecessary passing the REST URL in a servlet request that can otherwise be obtained via session information; and support for overriding methods using the Spring Framework @Transactional annotation on Jakarta Data repository interfaces. Further details on these releases may be found in the release notes for Community Edition 7.2026.6, Enterprise Edition 6.39.0 and Enterprise Edition 5.88.0.
Quarkus
The release of Quarkus 3.37.0 delivers bug fixes and notable changes such as: support for Hibernate ORM 7.4.0.Final, Hibernate Reactive 3.4.0.Final and Hibernate Search 8.4.0.Final; a new experimental extension, JLink, that generates a custom runtime image with jlink that includes only the necessary JDK modules in an application; and enabling reflection-free Jackson serializers by default. More details on this release may be found in the release notes.
WildFly
The first beta release of WildFly 41 ships with bug fixes, dependency upgrades and new features such as: support for handling data in the WildFly Transactions Subsystem during a graceful shutdown; and the ability to enable authentication requests to be signed and optionally encrypted via the request and request_uri parameters within the WildFly Elytron Subsystem. Further details on this release may be found in the release notes.
LangChain4j
The formal release (along with the twenty-seventh beta release) of LangChain4j 1.17.0 provides bug fixes, dependency upgrades and new features such as: a new DebatePlanner class to support the Debate agentic pattern; a new OracleChatMemoryStore class that adds an Oracle database for chat memory; and a new onUnmappedRawEvent streaming callback that allows for exposing raw streaming events that are not mapped by LangChain4j. More details on this release may be found in the release notes.
Eliya JDK
Asymm Systems has introduced Eliya JDK, their downstream distribution of OpenJDK that tracks the quarterly OpenJDK 25 Critical Patch Updates (CPUs) and delivers builds for Linux x86_64 and Linux aarch64. This initial release, version 25.0.3, is based on the Oracle Critical Patch Update Advisory for April 2026. Further details on this release may be found in the release notes and this InfoQ news story.
Hardwood
The release of Hardwood 1.0.0, a parser dedicated to the Apache Parquet file format, ships with notable changes such as: the close() method, one for both the ColumnReader class and the RowReader interface, are now idempotent to resolve a performance regression; an instance of the AvroRowReader class now honors column projections such that the DECIMAL, UUID, UINT_32, and FIXED columns are correctly read; and the entry point for the Hardwood class now accepts an implementation of the HardwoodContext interface for control over decoder thread-pool sizing and the ability to share a context across readers. More details on this release may be found in the release notes and InfoQ will follow up with a more detailed news story.
Endive
The release of Endive 1.0.0 delivers; WasmGC host integration with support for the externref value type as a Java Object such that host functions work naturally with GC types; and an optimization of tail call correctness by eliminating unnecessary stack frame allocation that benefits languages, such as CPython, that adopt tail calls in their interpreter loop.
Edive, a new JVM-native WebAssembly (Wasm) runtime, has its roots from Chicory, created in September 2023 by Benjamin Eckel, chief technical officer at Dylibso, and Andrea Peruffo, principal software engineer at IBM.
Open Source Sustainability Initiative
HeroDevs, the platform that identifies, remediates and prevents end-of-life open source risk, announced that they have joined the Commonhaus Foundation as the founding member of the Open Source Sustainability Initiative (OSSI) to "support sustainable open source ecosystems through improved lifecycle transparency and collaboration between maintainers, foundations, ecosystem partners, and the broader open source community." HeroDevs has already partnered with the Hibernate, Jackson, and Quarkus communities to support enterprises that need assistance in CVE remediation. HeroDevs also plans to partner with other projects under the auspices of the Commonhaus Foundation.
