The behavior of postgresql_ext.BinaryJSONField.contains() has changed.
Previously, passing a string to this method would perform a JSON key exists
check (? operator) instead of JSON contains (@> operator). As of 3.18.0,
this special-case has been removed and the contains() method always uses
the JSONB contains operator (@>). For the old behavior of checking
whether a key exists, use the BinaryJSONField.has_key() method. See #2984 for
discussion.
- Add options to URL-unquote user and password when using the
db_urlhelpers, see #2974 for discussion. - Support using
postgresql://URLs when connecting to psycopg3.
