Micronaut Framework 4.3.0 Released!
by Sergio Del Amo CaballeroMicronaut Core
Micronaut Core contains several improvements, including performance optimizations and enhancements to the Kotlin Symbol Processing (KSP) integration.
Kotlin 1.9.22
This minor release updates to Kotlin 1.9.22 and KSP 1.9.22-1.0.17.
New Modules
Micronaut Chabots
Micronaut Chatbots eases the creation of ChatBots (in this first release, with support for Telegram and Basecamp).
Micronaut EclipseStore
Micronaut EclipseStore is a new module which adds integration with EclipseStore. Eclipse Store is the successor of the MicroStream project., Technically this project is identical to MicroStream 8, which was the last stable version of MicroStream itself.
EclipseStore is a breakthrough Java-native persistence layer built for cloud-native microservices and serverless apps.
EclipseStore is also great for monoliths and runs on Android mobile, edge, and embedded devices.
Expression Language Support
Micronaut Multi-tenancy
Micronaut Multi-tenancy allows using the current request tenant ID with Micronaut Expression Language.
Micronaut Cache
Micronaut Cache adds support for conditional caching with expression language expressions.
@Cacheable(condition = "#{id.value > 5}")
public String get(Id id) {
return repository.get(id);
}
Moreover, it updates to:
- Infinispan 14.0.22
- Hazelcast 5.3.6
Build Plugins
Native Image Build Tools
Micronaut Gradle Plugin and Micronaut Maven Plugin plugins update to Native Image Build tools 0.10.0.
AmazonLinux:2023 base image
Micronaut Gradle Plugin task buildNativeLambda and Micronaut Maven Plugin goal mvn package -Dpackaging=docker-native -Dmicronaut.runtime=lambda generates a GraalVM native executable inside a Docker container to be deployed in AWS Lambda Custom runtime. They both use amazonLinux:2023 as base image.
Micronaut Gradle Plugin
Micronaut Gradle Plugin improves the docker support – with multi-layer docker files and changes the default base image to gr.dev/chainguard/wolfi-base:latest.
Micronaut Maven Plugin
Micronaut Maven Plugin improves its Java 21 support.
Micronaut Platform BOM
Micronaut Platform Bill of Materials (BOM) inlines all the versions defined in the different modules BOMs, to allow users to override any dependency version by simply overriding the corresponding property. It is noteworthy that this was previously feasible with Micronaut framework 3, and the aforementioned behavior has been restored.
Cloud
Micronaut GCP
Micronaut GCP has added support for Pub/Sub Push subscriptions via a new @PushSubscription annotation. This enables the processing of Push messages using the same programming model as the existing support for Pull subscriptions. With Push subscriptions, the PubSub service pushes messages to your application via HTTP, as opposed to the Pull style of subscription which requires your application to have a continually running background process to receive messages. Push subscriptions are generally required when using one of GCP’s serverless solutions, such as Cloud Run.
