Version 0.1.6

Features

• ARRAY support. Library now work with enums wrapped inside postgresql arrays
• Logging. Detected changes are being displayed in the console

Bugs

• Type "..." already exists during table creation.
  Enum types generated by alembic are now being converted to postgresql.ENUM(..., create_type=False) to avoid conflicts with lines generated by our library
• op.sync_enum_values does not work on columns that have constraints.
  Explicit definition of SQL operators added to keep constraint checks consistent across the renaming
