1.9.0

Released: December 15, 2022

feature

• [feature] [commands] Added new Alembic command alembic check. This performs the widely
  requested feature of running an "autogenerate" comparison between the
  current database and the MetaData that's currently set up for
  autogenerate, returning an error code if the two do not match, based on
  current autogenerate settings. Pull request courtesy Nathan Louie.

bug

• [bug] [tests] Fixed issue in tox.ini file where changes in the tox 4.0 series to the
  format of "passenv" caused tox to not function correctly, in particular
  raising an error as of tox 4.0.6.

• [bug] [typing] Fixed typing issue where revision.process_revision_directives
  was not fully typed; additionally ensured all Callable and Dict
  arguments to EnvironmentContext.configure() include parameters in
  the typing declaration.

  Additionally updated the codebase for Mypy 0.990 compliance.
