News and Updates

SQLAlchemy 1.4.39 is now available.

Release 1.4.39 fixes a single issue in 1.4.38 which is that a fix to the sqlalchemy.ext.mutable extension involving pickling failed to accommodate for the previous pickling format, which would impact an in-place upgrade of SQLAlchemy from 1.4.37 to 1.4.38 in an application that refers to existing pickled ORM objects, such as if they were stored in a cache. As SQLAlchemy's creator has at times been hit with this issue in production in days very long ago, we are rushing out a fix in 1.4.39 so that the legacy format for the "mutable" construct will remain consumable.

The complete changelog for 1.4.39 is at Changelog.
