0.9.6

Released: October 13, 2017

• [bug] [commands] Fixed a few Python3.6 deprecation warnings by replacing StopIteration
  with return, as well as using getfullargspec() instead of
  getargspec() under Python 3.

  References: #458

• [bug] [commands] An addition to #441 fixed in 0.9.5, we forgot to also filter
  for the + sign in migration names which also breaks due to the relative
  migrations feature.

• [autogenerate] [bug] Fixed bug expanding upon the fix for
  #85 which adds the correct module import to the
  "inner" type for an ARRAY type, the fix now accommodates for the
  generic sqlalchemy.types.ARRAY type added in SQLAlchemy 1.1,
  rendering the inner type correctly regardless of whether or not the
  Postgresql dialect is present.

• [bug] [mysql] Fixed bug where server default comparison of CURRENT_TIMESTAMP would fail
  on MariaDB 10.2 due to a change in how the function is
  represented by the database during reflection.

• [autogenerate] [bug] Fixed bug where comparison of Numeric types would produce
  a difference if the Python-side Numeric inadvertently specified
  a non-None "scale" with a "precision" of None, even though this Numeric
  type will pass over the "scale" argument when rendering. Pull request
  courtesy Ivan Mmelnychuk.

• [commands] [feature] The alembic history command will now make use of the revision
  environment env.py unconditionally if the revision_environment
  configuration flag is set to True. Previously, the environment would
  only be invoked if the history specification were against a database-stored
  revision token.

• [batch] [bug] The name of the temporary table in batch mode is now generated
  off of the original table name itself, to avoid conflicts for the
  unusual case of multiple batch operations running against the same
  database schema at the same time.

• [autogenerate] [bug] A ForeignKeyConstraint can now render correctly if the
  link_to_name flag is set, as it will not attempt to resolve the name
  from a "key" in this case. Additionally, the constraint will render
  as-is even if the remote column name isn't present on the referenced
  remote table.

• [bug] [py3k] [runtime] Reworked "sourceless" system to be fully capable of handling any
  combination of: Python2/3x, pep3149 or not, PYTHONOPTIMIZE or not,
  for locating and loading both env.py files as well as versioning files.
  This includes: locating files inside of __pycache__ as well as listing
  out version files that might be only in versions/__pycache__, deduplicating
  version files that may be in versions/__pycache__ and versions/
  at the same time, correctly looking for .pyc or .pyo files based on
  if pep488 is present or not. The latest Python3x deprecation warnings
  involving importlib are also corrected.
