the :class:`.Numeric` and :class:`.Float` SQL types have been separated out so that :class:`.Float` no longer inherits from :class:`.Numeric`; instead, they both extend from a common mixin :class:`.NumericCommon`. This corrects for some architectural shortcomings where numeric and float types are typically separate, and establishes more consistency with :class:`.Integer` also being a distinct type. The change should not have any end-user implications except for code that may be using ``isinstance()`` to test for the :class:`.Numeric` datatype; third party dialects which rely upon specific implementation types for numeric and/or float may also require adjustment to maintain compatibility.
