Introspections for JDK 14 Records

    It is now possible to define bean introspections on JDK 14+ record types (note these currently require the flag to the compiler and JVM).

    @Client + Kotlin

    @Client interfaces now support suspend methods!

    Default Environment

    Micronaut 2.1 introduces the concept of a default environment. One or more default environments can be set and they will apply if no other environments are explicitly specified or deduced. See the for information on how to use this new feature.

    @Order Annotation

    The annotation has been added to support supplying bean order for factory methods or for those who prefer the use of annotations over the Ordered interface.

    Kotlin 1.4

    Micronaut now ships with Kotlin 1.4 for those users using Kotlin.

    Build Features

    New Gradle Plugin

    A new Gradle plugin is available that provides a more expressive way to define a Micronaut application and includes awesome new features for GraalVM Native Image and Docker. The minimum required build to build a Micronaut application is now:

    Micronaut Minimal Gradle Build

    Building a Native Image is then as simple as:

    Whilst building a docker image using GraalVM Native Image can be done with:

    Client Binding API

    A new API has been created to allow for binding declarative HTTP client method arguments to an HTTP request. See the for more information.

    Websocket Improvements

    Query parameters are now respected and bindable in the Micronaut websocket support.

    HttpResponse Improvements

    Cookies in HTTP responses from the client side are now retrievable on the HttpResponse. These are the cookies found in the Set-Cookie header.

    Cloud Features

    Support for Oracle Cloud SDK

    A new GraalVM Native Image compatible module for Oracle Cloud SDK has been added allowing you to use any part of the Oracle Cloud SDK with Native Image and also enhancing the SDK with RxJava 2 support.

    Support for Oracle Function

    Support has been added for building Oracle Functions deployable to Oracle Cloud including the ability to compute the functions in native images using GraalVM.

    Support for Google Pub/Sub

    Thanks to Vinicius Carvalho at Google, Micronaut now features dedicated support for for seamless messaging in Google Cloud.

    Support for Google Cloud Log Format

    Thanks to at Google, Micronaut can now output logs in the official JSON format supported by Stackdriver on Google Cloud

    Liveness/Readiness Probes

    Micronaut’s /health endpoint now allows you to distinguish liveness and readiness probes at the URIs /health/liveness and /health/readiness. Micronaut Launch’s Kubernetes support has been updated to generate a Kubenetes descriptor that is configured to with these probe endpoints by default.
