SQLAlchemy 2.0.25 is now available.

This release includes a fix for an issue found in the asyncio system, where an engine that's been disposed using the Engine.dispose() method, as would be done when moving the engine across a process boundary, then used again for new connectivity, would inadvertently use a threading.Lock internally which can cause deadlocks when used in an asyncio context.

The release also includes a "preview" backport of the asyncio-compatible dialect for Oracle using the newly introduced asyncio support in the oracledb DBAPI library.
