Announcing Vitess 14

This post announces the general availability of Vitess 14, highlighting key improvements in usability and reliability. It details the GA status of Online DDL and the Gen4 planner becoming the default. Usability enhancements include command-line syntax deprecation warnings, the introduction of the new gRPC API for vtctld (VtctldServer) and its client (vtctldclient) with transition guidance, and the beta release of VTAdmin as a unified cluster management API and UI. Reliability improvements for VTOrc (still experimental) include better integration with Vtctld and federation handling, along with augmented Emergency Reparent Shard capabilities. Performance benchmarks show a ~10% improvement attributed to the removal of internal SAVEPOINT query execution.
