Version 1.0

Unreleased

  • Drop support for Python 2.6 and 3.3.
  • Optimize how timestamps are serialized and deserialized. (#13)
  • base64_decode raises BadData when it is passed invalid data. (#27)
  • Ensure value is bytes when signing to avoid a TypeError on Python 3. (#29)
  • Add a serializer_kwargs argument to Serializer, which is passed to dumps during dump_payload. (#36)
  • More compact JSON dumps for unicode strings. (#38)
  • Use the full timestamp rather than an offset, allowing dates before 2011. (#46)
  • Detect a sep character that may show up in the signature itself and raise a ValueError. (#62)
  • Use a consistent signature for keyword arguments for Serializer.load_payload in subclasses. (#74, #75)
  • Change default intermediate hash from SHA-1 to SHA-512. (#80)
  • Convert JWS exp header to an int when loading. (#99)

Version 0.24

Released 2014-03-28

  • Added a BadHeader exception that is used for bad headers that replaces the old BadPayload exception that was reused in those cases.

Version 0.23

Released 2013-08-08

  • Fixed a packaging mistake that caused the tests and license files to not be included.

Version 0.22

Released 2013-07-03

  • Added support for TimedJSONWebSignatureSerializer.
  • Made it possible to override the signature verification function to allow implementing asymmetrical algorithms.

Version 0.21

Released 2013-05-26

  • Fixed an issue on Python 3 which caused invalid errors to be generated.

Version 0.20

Released 2013-05-23

  • Fixed an incorrect call into want_bytes that broke some uses of itsdangerous on Python 2.6.

Version 0.19

Released 2013-05-21

  • Dropped support for 2.5 and added support for 3.3.

Version 0.18

Released 2013-05-03

  • Added support for JSON Web Signatures (JWS).

Version 0.17

Released 2012-08-10

  • Fixed a name error when overriding the digest method.

Version 0.16

Released 2012-07-11

  • Made it possible to pass unicode values to load_payload to make it easier to debug certain things.

Version 0.15

Released 2012-07-11

  • 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

Released 2012-06-29

  • 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

Released 2012-06-10

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

Version 0.12

Released 2012-02-22

  • 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

Released 2011-07-07

  • Fixed an uncaught value error.

Version 0.10

Released 2011-06-25

  • 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.
