News and Updates

SQLAlchemy release 1.3.22 is now available.

An immediate release of 1.3.22 was necessary due to a regression in the Oracle dialect, where the new isolation level feature would result in a connectivity failure for Oracle database connections that do not have access to the v$transactions system view which is a common scenario for Oracle. The new logic will gracefully degrade to the pre-1.3.21 behavior if this view is not available or if any other errors occur while retrieving the default isolation level.

As is the case with all releases, we'd like to thank all the contributors who helped to quickly identify this issue.

Changelog for 1.3.22 is at Changelog.
