Changes in Micronaut Core include: a refactoring of the IoC container and compile-time infrastructure (e.g., bean resolution, qualifier handling and annotation processing) for reducing runtime work and improving predictability; nullability support using [JSpecify](https://jspecify.dev/); and support for resilience and context propagation with [programmatic retry](https://docs.micronaut.io/snapshot/guide/#_programmatic_retry) and [circuit breaker APIs](https://docs.micronaut.io/snapshot/guide/#_programmatic_circuit_breaker). [Sergio Del Amo Caballero](https://www.linkedin.com/in/sergiodelamo/), Principal Member of the Technical Staff at Oracle and Committer to the Micronaut and Grails frameworks, described the significance of this release, writing: Micronaut 4 was [introduced]almost three years ago, so Micronaut 5 is both a major framework release and a broad platform refresh across more than 70 Micronaut modules.
