PuTTY 0.65 supports the newer message type. Additionally, PuTTY snapshots support newer protocols like curve25519 kex and the chacha20 cipher, which are a really good idea. WinSCP should update to at least 0.65, and the WinSCP team should notify the OpenSSH developers of the minimum version number that will support the new message type, so they can limit the blacklist to older versions.
