MicroProfile
The release of MicroProfile 7.0 delivers specification updates to: MicroProfile Telemetry 2.0; MicroProfile Open API 4.0; Rest Client 4.0; and Fault Tolerance 4.1.
Major changes in this release include: the move of the MicroProfile Metrics 5.1 specification to the set of standalone specifications; and a dependency on the Jakarta EE 10 Core Profile instead of packaging the individual specifications. These changes are reflected in the specification diagram below.
More details on this release may be found in the release notes and InfoQ will follow up with a more detailed news story.
Quarkus
Quarkus 3.13.3, the third maintenance release, features bug fixes and improvements in documentation. The most significant change is the downgrade of Apache Commons Lang from 3.16.0 to 3.14.0 due to a change in behavior as to the default source of entropy. This had caused some severe issues (including the application completely stalling) with Liquibase in particular. More details on this release may be found in the changelog.
Helidon
Versions 3.2.9 and 2.6.8 of Helidon are bug fix and dependency upgrade releases for the 3.0 and 2.0 release trains, respectively. Notable changes include: a resolution to the getOrdinal() method, defined in implementations of the ConfigSource interface, returning the wrong ordinal value for system property and environment variable configuration sources; and a removal of headers that do not affect CORS decision-making from request adapter logging output. More details on these releases may be found in the release notes for version 3.2.9 and version 2.6.8.
Infinispan
The third development release of Infinispan 15.1.0 delivers notable changes such as: support for nested queries with Ickle, Infinispan's query language; a resolution to a NullPointerException thrown from the acquireKeyFromContext() method, defined in the PersistenceManagerImpl class, when an entry is not found in an instance of the InvocationContext interface; and an improved EmbeddedTransactionManager class to ensure proper communication when throwing an exception for asynchronous operations.
Kotlin
The release of Kotlin 2.0.20 provides bug fixes and many new features such as: improved handling of the '$' character in literals; a change in how compiler features being rolled out are enabled and disabled in the compiler plugin CLI using strong skipping and non-skipping group optimizations; and support for default parameters in abstract and open functions annotated with @Composable. More details on this release may be found in the release notes.
Apache Software Foundation
Apache Maven 3.9.9 ships with big fixes, dependency upgrades and notable changes such as: the addition of contextual information for descriptor warnings that eliminates confusion; and a resolution to a NullPointerException from deploying a plugin.xml file in the presence of tags. More details on this release may be found in the release notes.
JHipster
The release of JHipster Lite 1.16.2, 1.16.1 and 1.16.0 ship with bug fixes, improvements in documentation, dependency upgrades and notable changes such as: the new landscape view; dependency upgrades to Angular 18.2.0 and Typescript ESLint 8.1.0; and a resolution to Cypress configuration issues with Vue.
