SunOS 4.1.4 (aka Solaris 1.1.?(1 maybe?  It's been a long time now.))
was the final release of SunOS 4.  It was basically 4.1.3_U1 with a
couple of other minor fixes merged in.  I spent a very long time
porting software from SunOS  4 to Solaris 2.3|4|5 during that time as
we transitioned from our older Sun4c|m based servers and hosts to
Sun4u (which of course only ran Solaris 2.5 and beyond (or Solaris 4
with patches, but those weren't general release and outside of Sun and
Pixar, I don't know anyone who had access to these)).
