 - EloquentEncryption now uses `Illuminate\Contracts\Encryption\Encrypter` contract.
 - **BC** If relying on 1.x use `encryptString()` or `decryptString()` functions **if you are using this encryption elsewhere in your application**. As the default encrypt/decrypt function now serialize values automatically, this may cause unexpected errors during decrypting.
