0.2.2

Released: Mon Mar 12 2012

• [feature] Informative error message when op.XYZ
  directives are invoked at module import time.

• [bug] Fixed inappropriate direct call to
  util.err() and therefore sys.exit()
  when Config failed to locate the
  config file within library usage.

• [bug] Autogenerate will emit CREATE TABLE
  and DROP TABLE directives according to
  foreign key dependency order.

• [bug] implement 'tablename' parameter on
  drop_index() as this is needed by some
  backends.

• [feature] Added execution_options parameter
  to op.execute(), will call execution_options()
  on the Connection before executing.

  The immediate use case here is to allow
  access to the new no_parameters option
  in SQLAlchemy 0.7.6, which allows
  some DBAPIs (psycopg2, MySQLdb) to allow
  percent signs straight through without
  escaping, thus providing cross-compatible
  operation with DBAPI execution and
  static script generation.

• [bug] setup.py won't install argparse if on
  Python 2.7/3.2

• [feature] script_location can be interpreted
  by pkg_resources.resource_filename(), if
  it is a non-absolute URI that contains
  colons. This scheme is the same
  one used by Pyramid.

• [feature] added missing support for
  onupdate/ondelete flags for
  ForeignKeyConstraint, courtesy Giacomo Bagnoli

• [bug] fixed a regression regarding an autogenerate
  error message, as well as various glitches
  in the Pylons sample template. The Pylons sample
  template requires that you tell it where to
  get the Engine from now. courtesy

• [bug] drop_index() ensures a dummy column
  is added when it calls "Index", as SQLAlchemy
  0.7.6 will warn on index with no column names.
