0.9.3

Released: July 6, 2017

• [feature] [runtime] Added a new callback hook
  EnvironmentContext.configure.on_version_apply,
  which allows user-defined code to be invoked each time an individual
  upgrade, downgrade, or stamp operation proceeds against a database.
  Pull request courtesy John Passaro.

• [autogenerate] [bug] Fixed bug where autogen comparison of a Variant datatype
  would not compare to the dialect level type for the "default"
  implementation of the Variant, returning the type as changed
  between database and table metadata.

• [bug] [tests] Fixed unit tests to run correctly under the SQLAlchemy 1.0.x series
  prior to version 1.0.10 where a particular bug involving Postgresql
  exclude constraints was fixed.
