- HashiCorp Vault support (Experimental)
- Oracle OCI Vault support (Experimental)
- Oracle OCI Object Storage support (Experimental)
- Neo4J support (Experimental)
- Micrometer metrics support (Experimental)
- gRPC native image support

Experimental feature APIs are subject to change.
Users of the current OCI Object Storage extension (helidon-integrations-cdi-oci-objectstorage) are encouraged
to look at the new OCI Object Storage support (helidon-integrations-oci-objectstorage). The old OCI object
storage support will be deprecated in a future release.
Compatibility
2.3.0 is API compatible with 2.2.0.
There is a behavior change related to Java marshalling in gRPC. io.helidon.grpc.core.JavaMarshaller has
been deprecated and disabled by default. It's use is not recommended for production and it will be removed
in Helidon 3.0. If you need to use the JavaMarshaller you can re-enable it by setting the
grpc.marshaller.java.enabled configuration property to true.
