Hi everyone,
The Apache Polaris community is pleased to announce Apache Polaris 1.4.0. Apache Polaris 1.4.0 is our first release post-graduation. It introduces several key advancements in security, cloud integration, and observability. This release significantly enhances credential vending with support for AWS STS session tags, storage-scoped credentials, and principal-based subscoping. Observability is improved with the ability to persist Iceberg metrics directly to the database and refined privilege requirements for metrics reporting. Cloud capabilities are expanded through S3 KMS encryption support and more precise Azure ADLS hierarchical namespace management. Additionally, the release adds CockroachDB support for relational persistence, integrates the Kubernetes Gateway API into the Helm chart, and migrates to a Guava-based rate limiter for improved stability.
