News and Updates

SQLAlchemy release 1.3.0b3 is now available.

Release 1.3.0b3 should hopefully be the last beta release for 1.3, as no additional major changes are planned. This release adds further restrictions on deprecated behaviors, most notably removing most instances of automatic coercion of Python strings that contain SQL fragments into text() objects; this behavior has been emitting warnings since 1.0 so should not be something in use by applications by now; as it has become an obscure feature it starts to look more like a bug rather than a deprecated behavior, so the warnings are now full exception messages.

The release also includes a variety of related improvements in the area of SQL identifiers and quoting, as well as some ORM-specific improvements. Finally, support for the Nose testing framework has been removed; SQLAlchemy has standardized on Py.test for some years now and Nose no longer worked as a test platform under Python 3 in any case.
