nessie-model-jakarta is effectively the same as nessie-model, but it is _not_ a multi-release jar and retains the jakarta annotations in the canonical classes. Please note that this artifact will go away, once Nessie no longer support Java 8 for clients. Therefore, do _not_ refer to this artifact - it is only meant for consumption by Nessie-Quarkus.

There is a newer version: 0.95.0
