Release notes

Sourced from sqlalchemy's releases.

2.0.48

Released: March 2, 2026

engine

• [engine] [bug] Fixed a critical issue in Engine where connections created in conjunction with the DialectEvents.do_connect() event listeners would receive shared, mutable collections for the connection arguments, leading to a variety of potential issues including unlimited growth of the argument list as well as elements within the parameter dictionary being shared among concurrent connection calls. In particular this could impact do_connect routines making use of complex mutable authentication structures.
