ABAC 2.1.0
----------
- The API visible to programmers is much richer and should make
  development simpler.  As part of this the libcreddy/libabac
  distinction has disappeared.  All libcreddy functions are now
  available through libabac.
- updated to use strongswan 4.6.4.  Strongswan 4.4.0 had become very
  outdated.
- Added more examples and documentation.
- add a new '--subject-link' option to creddy --attribute to hold the
  linking role
- add --dbdump option to abac_prover_yap to retrieve all prolog clauses
  stored in the db


WARNING
- There are occasional spurious error messages originated
  from Strongswan during access of the attribute credentials.  Those
  messages are due to libstrongswan mishandling certain values of
  authorizedKeyIdentifier in a non-destructive way.  While we are
  working with the strongswan developers to remove these messages, they
  should not affect ABAC in any way.

  Here are sample messages:

  L6 - keyIdentifier:  length of ASN.1 object invalid or too large
  L6 - authorityCertSerialNumber:  length of ASN.1 object invalid or too large

  Do report to us if your ABAC is not behaving as 
  expected and messages like above seem to be a factor..

ABAC 2.0.0
----------
- libabac now can handle RT2 attribute rules
  with dynamic and static constraints
