Read it at the original source: ## Questions this post answers ### What's new in Micronaut Core with the 5.1.0 release? Micronaut Core moves from 5.0.7 to 5.1.10, adding explicit @Introspected.Property, sequenced-collection injection, CDI integration hooks, KSP traversal of Kotlin inner classes, configuration-based logger levels, and per-service client SSL enabled by default. It also fixes request-bean binding, Jackson/introspection properties, AOP proxies, factory beans, and suspend-function type aliases. _daily.dev keeps backend teams current on framework releases before they plan a Micronaut upgrade._ ### What is Open DI and how does it relate to Micronaut? Open DI 1.0.0 is a CDI Lite implementation backed by Micronaut's compile-time dependency injection infrastructure, made possible by the Micronaut 5.1 release. The ODI runtime uses CDI APIs while the build relies on an annotation processor to generate Micronaut bean definitions and proxy classes; applications keep the ODI processor on the annotation processor path and run with the ODI CDI runtime plus the Jakarta CDI API. _Developers evaluating CDI Lite options can track Open DI's evolution alongside Micronaut on daily.dev._ ### Does Micronaut 5.1 support Spring Boot 4.1.0? Yes, Micronaut Spring 6.1.0 updates its Spring Framework dependency to 7.0.8 and adds compatibility with Spring Boot 4.1.0. This is part of the broader Micronaut 5.1.0 release, which also bumped Spring-related and other ecosystem module versions across data, cloud, and messaging integrations. _Teams bridging Micronaut and Spring ecosystems follow compatibility updates like this on daily.dev._ ## Similar posts on daily.dev - [Micronaut 5.0.0-RC1 Released\!](https://daily.dev/posts/micronaut-5-0-0-rc1-released--1t1y548lo) · Micronaut Framework · 0 upvotes · 0 comments - [Micronaut 5.0.0-M3 Released\!](https://daily.dev/posts/micronaut-5-0-0-m3-released--3trxdpoa6) · Micronaut Framework · 0 upvotes · 0 comments - [Introduction to Testing Micronaut With JUnit 5](https://daily.dev/posts/introduction-to-testing-micronaut-with-junit-5-mfe6twizm) · Baeldung · 3 upvotes · 0 comments --- Tags: [#java](https://daily.dev/tags/java), [#microservices](https://daily.dev/tags/microservices), [#kotlin](https://daily.dev/tags/kotlin), [#dependency-injection](https://daily.dev/tags/dependency-injection) [View this post on daily.dev](https://daily.dev/posts/micronaut-framework-5-1-0-released--my2nw0hm7) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Micronaut Framework 5.1.0 Released!","url":"https://daily.dev/posts/micronaut-framework-5-1-0-released--my2nw0hm7","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/micronaut-framework-5-1-0-released--my2nw0hm7"},"datePublished":"2026-07-27T20:26:07.396Z","dateModified":"2026-09-14T06:51:23.858Z","description":"Micronaut Framework 5.1.0 has been released, bringing updates across the entire ecosystem.
