Version 0.5.8 is released. Not a big one, has a few bugfixes, including a large improvement to the EXTRACT clause on PG. The upcoming beta of 0.6 is the one to watch for :).
Download SQLAlchemy 0.5.8 at: http://www.sqlalchemy.org/download.html 0.5.8 ===== - sql - The copy() method on Column now supports uninitialized, unnamed Column objects. This allows easy creation of declarative helpers which place common columns on multiple subclasses. - Default generators like Sequence() translate correctly across a copy() operation. - Sequence() and other DefaultGenerator objects are accepted as the value for the "default" and "onupdate" keyword arguments of Column, in addition to being accepted positionally. - Fixed a column arithmetic bug that affected column correspondence for cloned selectables which contain free-standing column expressions. This bug is generally only noticeable when exercising newer ORM behavior only availble in 0.6 via [ticket:1568], but is more correct at the SQL expression level as well. [ticket:1617] - postgresql - The extract() function, which was slightly improved in 0.5.7, needed a lot more work to generate the correct typecast (the typecasts appear to be necessary in PG's EXTRACT quite a lot of the time). The typecast is now generated using a rule dictionary based on PG's documentation for date/time/interval arithmetic. It also accepts text() constructs again, which was broken in 0.5.7. [ticket:1647] - firebird - Recognize more errors as disconnections. [ticket:1646]
