Summary
Apache Polaris 1.7.0, released August 2, 2026, focuses on correctness over features, addressing data corruption from network blips during retries. Key changes include idempotent writes for retry-safe table operations, a beta API for semantic models, stricter credential vending and location validation, and improved orphan file cleanup. These fixes matter because catalog bugs corrupt entire tables, not single queries, making this release critical for any team using Iceberg REST catalogs.
