Jan 1, 2026January 2026 (apache/gravitino) focused on delivering production-grade deployment tooling for Lance REST and tightening release governance across charts. Key outcomes include a complete Lance REST Helm chart with Kubernetes deployment templates, documented usage, and CI improvements; enhanced chart testing using a local registry; and release automation to synchronize Lance REST chart versioning with core and Iceberg REST charts. These efforts improved deployment reliability, reduced manual steps in releases, and established consistent chart metadata across the portfolio.
