1.9.0 - 2014-01-16

  • To discourage bad practices, remove use_https argument from the Yubico class constructor all together. Also update DEFAULT_API_URLS variable to contain full URLs with a scheme (e.g.

    If a user wants to use a custom non-https URL or URLs, they can still do that by passing api_urls argument with custom non-https URLs to the constructor.

  • Replace CA_CERTS_BUNDLE_PATH module level variable with a ca_certs_bundle_path argument which can be passed to the Yubico class constructor.

  • Update requests dependency from 1.2 to 2.2.

1.8.0 - 2013-11-09

  • Modify verify_multi method to throw if otp_list argument contains less than two items

  • Modify max_time_window argument in the verify_multi method to be in seconds (#19)

  • Modify verify_multi method to throw if delta between the first and last OTP timestamp is smaller than zero

  • Allow user to pass api_urls argument to the Yubico class constructor. This argument can contain a list of API urls which are used to validate the token.

  • Depend on newer version (1.2.3) of the requests library.

  • Update code and tests so they also work under Python 3.3

  • Change PyPi package name from yubico to yubico-client.

    This was done to prevent naming collisions and make creation of distribution specific packages (e.g. debian packages) easier.

  • If there are multiple interpretations for a given OTP, first try to find the one which matches the input OTP. If the one is found, use the input OTP, otherwise use random interpretation. -
