📣 Notice
This is the first preview release of 2.11.0! The motivation is to release new features and changes during the development lifecycle. This release is not feature complete for what the final 2.11.0 release will contain. This should only be used in development environments and not production. Additional preview releases will become available in subsequent weeks. Please check it out and give us feedback!
Preview Docker images are available under the synadia/nats-server Docker repo, not the official nats Docker repo.
