ABAC 2.1.0
----------
- libcreddy has been merged into libabac and creddy
  id and attribute credential generations are invoking
  libabac to do the work
- 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
- updated to use strongswan 4.6.4
- There are occasional error messages originated
  from Strongswan during access of the attribute
  credentials, but ABAC is still working as it should.
  Those messages are due to libstrongswan not
  handling certain value of authorizedKeyIdentifier
  as expected even though it really should not need
  to process for it (it does not need it).

  Here are sample of messages coming through the 
  stderr pipe,

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

  You might also see messages about authorityCertIssuer
  
  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
