ssh2 vs ssh1

[Dareen Framer]

Hello,

I was curious wether or not there was any great reason for people to
upgrade out of the version 1 series of SSH.  We are running a reasonable
late version of the ssh version 1 series, and have seen problems with other
admins moving on to the version 2 series.

Is there any inherent problems with version 1 or is it just different style
of encryption.

FYI we are using 1.2.25 on most of our servers  (protocol 1.5).
