SQLAlchemy 0.4.6 released

SQLAlchemy 0.4.6 is now available at:

http://www.sqlalchemy.org/download.html

This release includes some fixes for some refactorings in 0.4.5,  
introduces a new collate() expression construct, and improves the  
behavior of contains_eager(), a useful ORM option.

The 0.4 series is now in bugfix mode as we put the new features into  
0.5, which is in the current trunk.

changelog:

- orm
     - A fix to the recent relation() refactoring which fixes
       exotic viewonly relations which join between local and
       remote table multiple times, with a common column shared
       between the joins.

     - Also re-established viewonly relation() configurations
       that join across multiple tables.

     - contains_eager(), the hot function of the week, suppresses
       the eager loader's own generation of the LEFT OUTER JOIN,
       so that it is reasonable to use any Query, not just those
       which use from_statement().

     - Added an experimental relation() flag to help with
       primaryjoins across functions, etc.,
