A Preview of DuckDB v2.0

DuckDB v2.0, releasing this fall under the codename "Cyanoptera," introduces major features including DuckDB as a network server via the Quack extension, a new SQL parser, new storage format, triggers, the VARIANT data type, and asynchronous I/O built from over 10,000 commits since v1.5. The release marks a shift toward positioning DuckDB as a server that can serve databases over the network and allow remote connections through a new CONNECT statement, while also supporting query pushdown to PostgreSQL and MySQL. The major version bump includes breaking changes alongside significant new capabilities for both SQL-level features and engine improvements.
