=========
+- :bug:`2017` OpenSSH 7.7 and older has a bug preventing it from understanding
+ how to perform SHA2 signature verification for RSA certificates (specifically
+ certs - not keys), so when we added SHA2 support it broke all clients using
+ RSA certificates with these servers. This has been fixed in a manner similar
+ to what OpenSSH's own client does: a version check is performed and the
+ algorithm used is downgraded if needed. Reported by Adarsh Chauhan, with fix
+ suggested by Jun Omae.
