0.6.7

Released: September 9, 2014

• [bug] [mssql] Fixed bug in MSSQL dialect where "rename table" wasn't using
  sp_rename() as is required on SQL Server. Pull request courtesy
  Łukasz Bołdys.

• [feature] Added support for functional indexes when using the
  Operations.create_index() directive. Within the list of columns,
  the SQLAlchemy text() construct can be sent, embedding a literal
  SQL expression; the Operations.create_index() will perform some hackery
  behind the scenes to get the Index construct to cooperate.
  This works around some current limitations in Index
  which should be resolved on the SQLAlchemy side at some point.
