SQLAlchemy 0.7.2 Released

permalink

SQLAlchemy release 0.7.2 is now available. This release contains many bugfixes for bugs present in both the 0.6 and 0.7 series, as well as some 0.7 only fixes and a few new features.

0.7.2 includes behavioral enhancements to joined- and subquery-eager loading, a new feature to the typing system called with_variant() which allows a single type to act as a different type on selected backends, and improved string displays for several kinds of exceptions. The documentation has also been improved for clarity in many areas.

More features and documentation improvements are on the way for 0.7.3, including some new Declarative features. The current focus of development is on fully standardizing SQLAlchemy documentation and usage patterns on Declarative, with most direct usage of the mapper() function intended for special cases and custom ORM configurational layers, created either in-house or as part of external open source extension layers.

The full changelog for version 0.7.2 is at CHANGES.
