This does indeed seem to be the latest version. From 1995.

It sure seems to be able to do some neat things. Nice 2d and 3d
plots with mutliple images in a window. You can zoom and rotate
plots with the X controls. Nice colour abilities...

The licence is right too. This is copied from README.INSTALL

I took a quick look at the Plot/test_plotmtv.c function and
saw a few undocumented command line switches added by the Tela
folks. 

They have added a -filelist option which will accept data
file names from stdin, and -earlydelete to have plotmtv
delete the files when it's finished with them. This could
be a reasonable approach from octave, expecially since
plotmtv seems to accept binary format files. 

It would be better to be able to talk completely through
pipes. The code looks well organized, and changes should be easy
to make, ...

Just my 2c.
