+PAC transition
+--------------
+
+Beginning with release 1.20, the KDC will include minimal PACs in
+tickets instead of AD-SIGNEDPATH authdata.  S4U requests (protocol
+transition and constrained delegation) must now contain valid PACs in
+the incoming tickets.  If only some KDCs in a realm have been upgraded
+across version 1.20, the upgraded KDCs will reject S4U requests
+containing tickets from non-upgraded KDCs and vice versa.
+
+Triple-DES transition
+---------------------
+
+Beginning with the krb5-1.19 release, a warning will be issued if
+initial credentials are acquired using the des3-cbc-sha1 encryption
+type.  In future releases, this encryption type will be disabled by
+default and eventually removed.
