MicroProfile

The MicroProfile Working Group has released MicroProfile 4.1 featuring an update to the MicroProfile Health 3.1 API. New features in Health include: integration of the MicroProfile parent POM; supporting the new Startup Kubernetes probes by adding a @Startup health check group and /health/started endpoint; and clarifying that the property, mp.health.default.readiness.empty.response, which defaults to DOWN, is used only before user readiness checks are processed.

Work has already been underway for the upcoming release of MicroProfile 5.0, scheduled for the fourth quarter of 2021, in which developers may expect updates to all eight home-grown APIs: Config, Metrics, Health, Fault Tolerance, JWT Propagation, Rest Client, Open Tracing and Open API.

Quarkus

Red Hat has released Quarkus 2.0.3, the third maintenance release to Quarkus 2.0, featuring: bug fixes; improvements to the documentation; dependency upgrades to Hibernate ORM 5.5.4.Final and some SmallRye components; fix a continuous testing issue in which the @BeforeAll annotation does not report failures; and fix issues in which Redis breaks on live reload. More details may be found in the changelog and a migration guide is available for developers who wish to upgrade to Quarkus 2.0.

Hibernate

Hibernate ORM 5.5.4.Final was released featuring a new CamelCaseToUnderscoresNamingStrategy class to replace all dots with underscores, replace all camel casing with underscores, and generate all table names to lowercase. This was created in response to the popularity of Spring's SpringPhysicalNamingStrategy class. Other new features include: the ability of Hibernate to obtain IdentifierGenerator interface definitions from the BeanContainer interface when not registered; and running tests on JDK 18 early-access builds.

Hibernate Search 6.0.6.Final was released featuring a bug fix in which an AWS request signing will no longer produce an incorrect signature in specific cases involving a payload with non-ASCII characters.

Spring Framework

The first milestone release of Spring Security 5.6.0-M1 was made available featuring: an AuthorizationManager interface for method security; support for any data type in the OAuth2AccessTokenResponse class; and a separate repository for Spring Security samples.

RefactorFirst

Jim Bethancourt, principal software consultant at Improving, an IT services firm offering training, consulting, recruiting, and project services, has announced the initial release, version 0.1.0, of the RefactorFirst plugin for Maven. This new tool helps identify which classes in an application should be refactored first. There are plans to introduce an equivalent plugin for Gradle.

Apache Tika

Apache Tika has released version 2.0.0 of their metadata extraction toolkit. Formerly a subproject of Apache Lucene, this latest version includes a significant refactoring of the Apache Tika 1.x branch, modularization of the Parser modules, new modules within the Pipes modules, numerous bug fixes and dependency upgrades. More details may be found in the release notes. InfoQ will follow up with a more detailed news story.

Kotlin

Less than a month after the release of Kotlin 1.5.20, JetBrains has introduced the first milestone version of Kotlin 1.5.30, featuring a preview of new features such as: native Apple Silicon support that eliminates the need for the Rosetta Translation Environment; improved CocoaPods configuration with a new DSL format in the Gradle plugin; and improved debugging for Kotlin/JS applications with the new IR backend by generating JavaScript source maps. Developers may install version 1.5.30-M1 and experiment with these new features.

Scala

Shortly after the GA release of Scala 3.0, maintenance releases 3.0.1 and 3.0.2-RC1 were made available featuring a new @experimental annotation that explicitly marks definitions as experimental, improved compatibility in kind-projector mode, better error messages, and several bug fixes.
