Released: April 4, 2017

• [sql] [bug] Fixed regression released in 1.1.5 due to #3859 where
  adjustments to the "right-hand-side" evaluation of an expression
  based on Variant to honor the underlying type's
  "right-hand-side" rules caused the Variant type
  to be inappropriately lost, in those cases when we do want the
  left-hand side type to be transferred directly to the right hand side
  so that bind-level rules can be applied to the expression's argument.

• [sql] [bug] [postgresql] Changed the mechanics of ResultProxy to unconditionally
  delay the "autoclose" step until the Connection is done
  with the object; in the case where PostgreSQL ON CONFLICT with
  RETURNING returns no rows, autoclose was occurring in this previously
  non-existent use case, causing the usual autocommit behavior that
  occurs unconditionally upon INSERT/UPDATE/DELETE to fail.

misc

• [bug] [ext] Fixed regression released in 1.1.8 due to #3950 where the
  deeper search for information about column types in the case of a
  "schema type" or a TypeDecorator would produce an attribute
  error if the mapping also contained a column_property.
