Cong Zhao: "Apache Pulsar 4.0 has officially landed! With Pulsar SQL, revamped storage and security, and streamlined cloud-native deployments, this release pushes the boundaries of messaging and streaming tech. Check it out!"

I think they meant DLQ. Pulsar SQL has been deprecated

How can external community members contribute to it? I tried it but it's beyond my control! if the team can give us the basics for 4.1, we can contribute! @Lari Hotari @sijieg @merlimat

Blog post for 4.1 just went live: https://pulsar.apache.org/blog/2025/09/09/announcing-apache-pulsar-4-1/

I'm talking about the deprecated Pulsar SQL....? 🤔🧐 @Lari Hotari

yes, that must have been a mistake in the old Pulsar 4.0 tweet. The future of Pulsar SQL is in https://github.com/apache/pulsar-sql , however I haven't had a chance to spend any time on it. I hope that other Pulsar contributors could get it going. Pulsar SQL is still maintained in branch-3.0 so it's still usable with Pulsar 3.0.x.
