Version 2 Release

[creyD]

• Fixed Rename additonal_data to additional_data #1
• Fixed Inverse partial: bool = False because it is wrong #3

Notes:
You will need to change calls to create_obj_from_data according to #1 (rename additonal_data to additional_data)
You will need to change calls to update_obj_from_data according to #3 (if you supplied partial, you will need to reverse it: true -> false and false -> true)
