Future releases

Psycopg 3.2 (unreleased) ^^^^^^^^^^^^^^^^^^^^^^^^

• Add support for integer, floating point, boolean NumPy scalar types__ (:ticket:[#332](https://github.com/psycopg/psycopg/issues/332)).
• Add !timeout and !stop_after parameters to Connection.notifies() (:ticket:340).
• Add :ref:raw-query-cursors to execute queries using placeholders in PostgreSQL format (1ドル, 2ドル...) (:ticket:[#560](https://github.com/psycopg/psycopg/issues/560)).
• Add psycopg.capabilities object to :ref:inspect the libpq capabilities <capabilities> (:ticket:[#772](https://github.com/psycopg/psycopg/issues/772)).
• Add ~rows.scalar_row to return scalar values from a query (:ticket:[#723](https://github.com/psycopg/psycopg/issues/723)).
• Prepared statements are now :ref:compatible with PgBouncer <pgbouncer>. (:ticket:[#589](https://github.com/psycopg/psycopg/issues/589)).
• Add ~Connection.set_autocommit() on sync connections, and similar transaction control methods available on the async connections.
• Add support for libpq functions to close prepared statements and portals introduced in libpq v17 (:ticket:[#603](https://github.com/psycopg/psycopg/issues/603)).
• Add support for libpq encrypted and non-blocking query cancellation functions introduced in libpq v17 (:ticket:[#754](https://github.com/psycopg/psycopg/issues/754)).
• The !context parameter of sql objects ~sql.Composable.as_string() and ~sql.Composable.as_bytes() methods is now optional (:ticket:[#716](https://github.com/psycopg/psycopg/issues/716)).
• Disable receiving more than one result on the same cursor in pipeline mode, to iterate through ~Cursor.nextset(). The behaviour was different than in non-pipeline mode and not totally reliable (:ticket:[#604](https://github.com/psycopg/psycopg/issues/604)). The Cursor now only preserves the results set of the last ~Cursor.execute(), consistently with non-pipeline mode.
• Add ~Connection.cancel_safe() for encrypted and non-blocking cancellation If possible, use such method internally upon KeyboardInterrupt and Copy termination (:ticket:[#754](https://github.com/psycopg/psycopg/issues/754)).
• Add support for libpq function to retrieve results in chunks introduced in libpq v17 (:ticket:[#793](https://github.com/psycopg/psycopg/issues/793)).
