ChangeLog

0.2.2

• Fixed: Django admin needs to be able to create blank instances of the fields in order to create a new model. This broke with BaseEncryptedNumberField. (via defrex)
• Fixed: block_type wasn't added to the south rules. (via defrex)
• Fixed: Newer code paths with block_type specified couldn't reuse the cipher object on the field class. to_python was already redefining it before decrypting the value, but get_db_prep_value wasn't before encrypting. The first time you used a model it would be fine, but the second would fail. Thus the tests were passing but the classes were functionally useless in an application. (via defrex)
