OpenSSH 8.6 released

OpenSSH 8.6 is now available. The "ssh-rsa" signature scheme, which usesthe SHA-1 hash algorithm, will be disabled by default in the nearfuture. "Note that the deactivation of "ssh-rsa" signatures does notnecessarily require cessation of use for RSA keys. In the SSH protocol,keys may be capable of signing using multiple algorithms. In particular,"ssh-rsa" keys are capable of signing using "rsa-sha2-256" (RSA/SHA256),"rsa-sha2-512" (RSA/SHA512) and "ssh-rsa" (RSA/SHA1). Only the last ofthese is being turned off by default."
