News and Updates

SQLAlchemy 1.1.6 Released


SQLAlchemy release 1.1.6 is now available.

Release 1.1.6 continues to provide bug fixes and some new features within the 1.1 series. As we begin to lead into the development phase for 1.2 and solidify the 1.1 series as "done", additional behavioral improvements will more likely to be targeted at 1.2 rather than 1.1. Nevertheless, 1.1.6 includes a few fairly major behavioral improvements in the area of performance; some significant performance issues within the "joined eager loading" functionality were identified and repaired, which should cut the Python-level latency for such a query roughly in half, as well as an unnecessary SELECT which could emit when using the "eager defaults" feature was repaired.

Changelog for 1.1.6 is at Changelog.
