Not all SSH servers work properly. Various existing servers have
bugs in them, which can make it impossible for a client to talk to
if the server is a version which PuTTY's bug database does not know
about, then PuTTY will not know what bugs to expect.
-The Bugs panel allows you to manually configure the bugs PuTTY
-expects to see in the server. Each bug can be configured in three
-states:
+The Bugs and More Bugs panels (there are two because we have so many
+bug compatibility modes) allow you to manually configure the bugs
+PuTTY expects to see in the server. Each bug can be configured in
+three states:
\b \q{Off}: PuTTY will assume the server does not have the bug.
and terminate with an error along the lines of \q{Received
\cw{SSH2_MSG_CHANNEL_FAILURE} for nonexistent channel 256}.

+The SSH key exchange method that uses Diffie-Hellman group exchange
+was redesigned after its original release, to use a slightly more
+sophisticated setup message. Almost all SSH implementations switched
+over to the new version. (PuTTY was one of the last.) A few old
+servers still only support the old one.
+
+If this bug is detected, and the client and server negotiate
+Diffie-Hellman group exchange, then PuTTY will send the old message
+now known as \cw{SSH2_MSG_KEX_DH_GEX_REQUEST_OLD} in place of the new
+\cw{SSH2_MSG_KEX_DH_GEX_REQUEST}.
+
+This is an SSH-2-specific bug.
