Major changes in 1.19 (2021-02-01)
----------------------------------

Administrator experience:

* When a client keytab is present, the GSSAPI krb5 mech will refresh
  credentials even if the current credentials were acquired manually.

* It is now harder to accidentally delete the K/M entry from a KDB.

Developer experience:

* gss_acquire_cred_from() now supports the "password" and \ 
"verify"
  options, allowing credentials to be acquired via password and
  verified using a keytab key.

* When an application accepts a GSS security context, the new
  GSS_C_CHANNEL_BOUND_FLAG will be set if the initiator and acceptor
  both provided matching channel bindings.

* Added the GSS_KRB5_NT_X509_CERT name type, allowing S4U2Self
  requests to identify the desired client principal by certificate.

* PKINIT certauth modules can now cause the hw-authent flag to be set
  in issued tickets.

* The krb5_init_creds_step() API will now issue the same password
  expiration warnings as krb5_get_init_creds_password().

Protocol evolution:

* Added client and KDC support for Microsoft's Resource-Based
  Constrained Delegation, which allows cross-realm S4U2Proxy requests.
  A third-party database module is required for KDC support.

* kadmin/admin is now the preferred server principal name for kadmin
  connections, and the host-based form is no longer created by
  default.  The client will still try the host-based form as a
  fallback.

* Added client and server support for Microsoft's KERB_AP_OPTIONS_CBT
  extension, which causes channel bindings to be required for the
  initiator if the acceptor provided them.  The client will send this
  option if the client_aware_gss_bindings profile option is set.

User experience:

* kinit will now issue a warning if the des3-cbc-sha1 encryption type
  is used in the reply.  This encryption type will be deprecated and
  removed in future releases.

* Added kvno flags --out-cache, --no-store, and --cached-only
  (inspired by Heimdal's kgetcred).
