That might be, but configurations regarding that was still possible. With current systems that configuration is an error and ssh fails to work at all. > But of course you can make this change after upgrade - it's client-side. And if you have ssh-with-key-only root on some systems, it is very hard to change that setting in global ssh_config. Why do you bristle that much against documenting that in NEWS.debian.gz where it should be!?

Yea, I still have to have my own debian package of openssh due the fact that debian is _not_ sticking to mainline upstream choices and have some questionable patches in the package. Patches that upstream refused for security reasons. It would be not really more work to enable that too here. However, I also wrote a mail to upstream regarding that decision. I do not only want to only my systems being secure, I want to have that opportunity for others too. If blowfish is dropped from debian package, that would cut many others from using a secure algorithm. And I know many people that do not give a shit for security and just use lower secure algorithms.
