Changes 1.1.9:
A continuing stream of small regressions is leading us to have to put out \ 
releases every few days at the moment. This release includes a fix to a \ 
regression that was caused by a fix to a regression :), specifically the \ 
sqlalchemy.ext.mutable fix put out in 1.1.8. It also fixes a different \ 
regression in the typing system introduced in 1.1.5, and also has a regular bug \ 
fix for another issue regarding "connectionless" execution.
