Additional FYI.

I probably need to read the Change Notes - so probably it is not a 
surprise that Putty 0.64 is not (always) working.

I thought I only had one "old cbc" cipher active to support an old SSH 
client.

The surprising part is when sshd_config has this added:
ciphers 
aes128-ctr,aes192-ctr,aes256-ctr,chacha20-poly1305 at openssh.com,aes256-cbc
KexAlgorithms  
curve25519-sha256 at libssh.org,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1
macs hmac-sha2-256,hmac-sha2-512,hmac-sha1-96,hmac-sha1

openssh-7.0p1 sshd does actually ask for the password, rather than fail 
outright with protocol mismatch
(which is what it does without the "backwards-compatible" ciphers, et 
al, above., i.e., never gets to asking for password).
