DuckDB v2.0 turns the in-process engine into a networked server
DuckDB v2.0, "Cyanoptera," graduates the embedded database's quack extension to a stable client/server mode: any DuckDB process can now serve databases over the network and route queries straight to PostgreSQL and MySQL. Built on 10,000+ commits, the release also stabilizes extensions with a versioned C API and ABI guarantees. A single-binary analytical engine has quietly become a real database server.
