   the issue to our attention.
   [ISC-Bugs #41976]
 
+- The server nows checks both the address and length of a prefix delegation
+  when attempting to match it to a prefix pool.  This ensures the server
+  responds properly when pool configurations change such that once valid,
+  "in-pool" delegations are now treated as being invalid.  During lease
+  file loading at startup, the server will discard any PD leases that
+  are deemed "out-of-pool" either by address or mis-matched prefix length.
+  Clients seeking to renew or rebind such leases will get a response of
+  No Binding in the case of the former, and the prefix delegation with
+  lifetimes set to zero in the case of the latter.
