  initial counter. see <https://savannah.nongnu.org/support/?108114>.
* Added gnulib self-tests.
* API and ABI is backwards compatible with the previous version.

Version 1.12.4 (released 2012-06-17)

  This can be used when a single user carries multiple tokens (with
  different OATH secrets) and any of them should be permitted.
