Linuxeden开源社区Release 1.4.12 includes a variety of fixes including a SQL caching issue involving certain forms of queries. It also revises the format of the “empty IN” comparison to no longer use subqueries for most platforms which should eliminate compatibility and performance concerns that were reported by users. A fairly wide range of other bugs and regressions are also fixed.
Huge thanks to our users for getting us the information needed for fixes and to our growing development team for the great work!
The complete changelog for 1.4.12 is at Changelog.
SQLAlchemy 1.4.12 is available on the Download Page.
