  • ILP configuration to disconnect on errors to prevent data loss
  • New table writer metrics in the Prometheus metrics endpoint
  • Flag to report JIT compilation status in REST API
  • Icon in the web console that indicates JIT-enabled query execution
  • Optimized query performance for ORDER BY designated timestamp with filters
  • Improved DROP TABLE syntax to use with IF EXISTS
