It hasn't been that long, it's just that it was not actively
maintained for a long time, then recently we added some entries for
important user-visible changes. I don't think it is reasonable to
expect a full list of changes since the last real release of Octave,
or even since the 2.1.73 snapshot. But if there are additional
important changes that could cause trouble for users upgrading from
old versions of Octave, I think it would be good to include entries in
the NEWS file for them. I could also use help in generating those
entries.

Not quite. They still work, but they connect to a separate gnuplot
process from the one that is used by the Matlab-graphics-handle-style
plotting functions.
I've just checked in the following change to the NEWS file.
Thanks,
