9.4.5 update changes ECDSA fingerprint

Hello,
after upgrading omnibus version
gitlab-ce-9.4.4-ce.0.el7.x86_64
to
gitlab-ce-9.4.5-ce.0.el7.x86_64
the

git clone git@hostname:username/reponame.git

starts complaining about unknown host authencity (changed fingerprint):

The authenticity of host 'hostname:username (10.0.0.1)' can't be established.
ECDSA key fingerprint is SHA256:xxxxxxxx.
ECDSA key fingerprint is MD5:yyyyyyyy.
Are you sure you want to continue connecting (yes/no)?

There was no change on my client so it seems something changed on the server.
This seems to be bug to me. Anyone else stumbled upon this?

I’ve got the same issue.
