Unified documentation for Kerberos V5 is available in both HTML and
PDF formats.  The table of contents of the HTML format documentation
is at doc/html/index.html, and the PDF format documentation is in the
doc/pdf directory.

Additionally, you may find copies of the HTML format documentation
online at

    http://web.mit.edu/kerberos/krb5-latest/doc/

DES transition
--------------

The Data Encryption Standard (DES) is widely recognized as weak.  The
krb5-1.7 release contains measures to encourage sites to migrate away
from using single-DES cryptosystems.  Among these is a configuration
variable that enables "weak" enctypes, which defaults to "false"
beginning with krb5-1.8.


Major changes in 1.12.5 (2015-12-16)
------------------------------------

This is a bugfix release.  The krb5-1.12 release series has reached

should prefer the krb5-1.14 release series or later.

Major changes in 1.12 (2013-12-10)
----------------------------------

Developer experience:

* Add a plugin interface to control krb5_aname_to_localname and
  krb5_kuserok behavior.

* Add a plugin interface to control hostname-to-realm mappings and the
  default realm.

* Add GSSAPI extensions for constructing MIC tokens using IOV lists.

Administrator experience:

* Principal entries may now refer to the names of policies which do
  not exist as policy objects in the database.  Policy objects may now
  be deleted whether or not principals reference their names.  A
  principal which references a nonexistent policy name will behave as
  if it does not reference a policy.

* Add support for having no long-term keys for a principal. This can
  be useful if the principal is only intended to be used with PKINIT
  or OTP preauthentication.

* Add collection support to the KEYRING credential cache type on
  Linux, and add support for persistent user keyrings and larger
  credentials on systems which support them.

* Add a FAST OTP preauthentication module for the KDC which uses
  RADIUS to validate OTP token values.

* Add an experimental pluggable interface for auditing KDC
  processing. This interface may change in a backwards-incompatible
  way in a future release.

Performance:

* The AES-based encryption types will use AES-NI instructions when
  possible for improved performance.
