Apr 1, 2026April 2026 – Delivered automation, security hardening, and CI reliability improvements for Apache Gravitino. Highlights include: 1) an interactive release manager skill with 7-stage workflow and mock mode; 2) a REST client path segment URL encoding helper with broad application across operations and 29 unit tests; 3) DataSourceUtils updates to block H2 JDBC URLs and drivers with clear errors and 4 tests; 4) a regression fix for JobManager cleanup that caused premature deletion during staging cleanup, resolved by reverting the change and stabilizing CI. These changes reduce release risk, prevent misconfiguration, and accelerate the development and testing cycle.

Dec 1, 2025December 2025—Major quality and velocity boost across data catalog, Spark templates, and release hygiene. Delivered server-side creation modes for Lance-backed tables, added schema-aware rename for ManagedTables, and reinforced drop semantics for lakehouse-generic catalogs with full tests. Launched a built-in Spark job template framework with validation improvements and documentation. Strengthened release and packaging lifecycle with dependabot cadence, release-task improvements, and security dependency updates. Fixed observability gaps by correcting REST logger appender wiring to ensure error traces reach server logs.
