• Fix segfault fetching arrays of strings or timestamps after closing the connection (:ticket:[#1428](https://github.com/psycopg/psycopg/issues/1428)).

Psycopg 3.3.6 ^^^^^^^^^^^^^

• Add support for Python 3.15 (:ticket:[#1245](https://github.com/psycopg/psycopg/issues/1245)).

• Fix dumping of nested subclasses of lists as arrays (:ticket:[#1398](https://github.com/psycopg/psycopg/issues/1398)).
• Discard prepared statements upon :sql:DEALLOCATE ALL (:ticket:[#1408](https://github.com/psycopg/psycopg/issues/1408)).
