Version 0.17

~~~~~~~~~~~~

Version 0.16

~~~~~~~~~~~~

- made it possible to pass unicode values to `load_payload` to make it

  easier to debug certain things.

Version 0.15

~~~~~~~~~~~~

- made standalone `load_payload` more robust by raising one specific

  error if something goes wrong.

- refactored exceptions to catch more cases individually, added more

  attributes.

- fixed an issue that caused `load_payload` not work in some situations

  with timestamp based serializers

- added an `loads_unsafe` method.

Version 0.14

~~~~~~~~~~~~

- API refactoring to support different key derivations.

- Added attributes to exceptions so that you can inspect the data even

  if the signature check failed.

Version 0.13

~~~~~~~~~~~~

- Small API change that enables customization of the digest module.

Version 0.12

~~~~~~~~~~~~

- Fixed a problem with the local timezone being used for the epoch

  calculation.  This might invalidate some of your signatures if you

  were not running in UTC timezone.  You can revert to the old behavior

  by monkey patching itsdangerous.EPOCH.

Version 0.11

~~~~~~~~~~~~

- Fixed an uncought value error.

Version 0.10

~~~~~~~~~~~~

- Refactored interface that the underlying serializers can be swapped by

  passing in a module instead of having to override the payload loaders

  and dumpers.  This makes the interface more compatible with Django's

  recent changes.
