 1) Modified server-side defaults
 
    We've modified some configuration defaults in sshd:
 
-      - PasswordAuthentication defaults to "no".
-
-      - LoginGraceTime defaults to 120 seconds instead of 600.
-
+      - UsePAM defaults to "yes".
       - PermitRootLogin defaults to "no".

-      - X11Forwarding defaults to "yes" (it's a threat to the client,

 2) Modified client-side defaults
 
    We've modified some configuration defaults in ssh:
 
       - CheckHostIP defaults to "no".
+      - VerifyHostKeyDNS defaults to "yes" if built with LDNS.

+5) TCP wrappers
+
+   Support for TCP wrappers was removed in upstream 6.7p1.  We've
+   added it back by porting the 6.6p1 code forward.
+
+6) DSA keys
+
+   DSA keys were disabled by default in upstream 6.9p1.  We've added

+
+7) Agent client reference counting
+
+   We've added code to ssh-agent.c to implement client reference
+   counting; the agent will automatically exit when the last client
+   disconnects.
+
+8) Class-based login restrictions
+
+   We've added code to auth2.c to enforce the host.allow, host.deny,
+   times.allow and times.deny login class capabilities.
+
+9) HPN
+
+   We no longer have the HPN patches (adaptive buffer size for
+   increased throughput on high-BxD links), but we recognize and
+   ignore HPN-related configuration options to avoid breaking existing
+   configurations.
