Is there some new support for native images in Spring Boot 3.2.x, or why don't we need this anymore?

[gschlueter-jaconi]

Sadly, no. Since there is no such image yet for Java 21, the only easy way to produce a native image is to use buildpacks. We can think about pushing non-native ARM images though.

[jnodorp-jaconi]

Can we drop this entirely? Should be the default.
