Spring Batch DB Cluster Partitioning 3.0.0 — distributed partitioning with just a database, now on Spring Boot 4 & Java 21

spring-batch-db-cluster-core 3.0.0 is live on Maven Central. This is the biggest release of the project so far — a full platform upgrade plus a batch of new capabilities and correctness fixes.

If you haven't seen the project before: it runs partitioned Spring Batch jobs across multiple JVM nodes, coordinated entirely through your existing relational database — no Kafka, no RabbitMQ, no ZooKeeper. The database is the coordination plane. It's Apache-2.0, peer-reviewed and published in JOSS.
