psycopg release notes

Future releases

Psycopg 3.3.7 (unreleased) ^^^^^^^^^^^^^^^^^^^^^^^^^^

• Fix segfault fetching arrays of strings or timestamps after closing the connection (:ticket:[#1428](https://github.com/psycopg/psycopg/issues/1428)).
• Fix ~Connection.cancel_safe() failing if the cancel connection is not ready immediately, for instance on a slow network (:ticket:[#1440](https://github.com/psycopg/psycopg/issues/1440)).

Current release

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

• Add support for Python 3.15 (:ticket:[#1245](https://github.com/psycopg/psycopg/issues/1245)).
• Improve performance of async queries by reducing the overhead of the !wait_async() function (:ticket:[#1331](https://github.com/psycopg/psycopg/issues/1331)).

• 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)).
• Better guards dumping large Python !int to binary numeric (:ticket:[#1414](https://github.com/psycopg/psycopg/issues/1414)).

Psycopg 3.3.5 ^^^^^^^^^^^^^

• Discard prepared statements upon :sql:ALTER * or DISCARD * (:ticket:[#1307](https://github.com/psycopg/psycopg/issues/1307)).
• Fix !ProgrammingError when dumping non-!None values with no !NoneType dumper registered in python implementation (:ticket:[#1325](https://github.com/psycopg/psycopg/issues/1325)).
• Fix !wait_selector wait function to not raise !KeyError

Summary by cubic

Updates the psycopg[binary] minimum version in the backend from 3.2.9 to 3.3.6, bringing in fixes for async query performance, query cancellation on SystemExit, and correct handling of prepared statements after DEALLOCATE ALL.

Migration

• None required; the version constraint change only lifts the minimum and uv.lock is regenerated to resolve 3.3.6.

^{Written for commit 21d4dfa. Summary will update on new commits.}
