          Upon deeper analysis, you are correct. I was a bit floored by what appeared to be a power curve near the beginning, but after actually plotting, it’s a simple linear trend:

          Data

          Code 
            curl https://www.openssh.com/releasenotes.html \
     | sed -nr '/^<h3><a/s/.*OpenSSH ([0-9.]+).*\(([0-9-]+)\).*/\2\t\1/p' \
     | sort \
     | sed -r 's|([0-9]+)\.([0-9]+)\.([0-9]+)|\1.\2\3|' \
     | column -t -N 'Date,Version' > openssh.dat
  head openssh.dat

          Which yields:

          Date        Version
2000-03-05  1.22
2000-03-24  1.23
...
2025-02-18  9.9
2025-04-09  10.0

          Fit

          Code 
            gnuplot -p -e '
    set xdata time;
    set timefmt "%Y-%m-%d";
    set xlabel "Date"; set format x "%Y";
    set ylabel "Version";
    f(x) = a*x + b;
    a = 1e-10; b = -100;
    fit f(x) "openssh.dat" using 1:2 via a,b;
    set label 1 sprintf("Fit: Version = (%.3e * Date) %.3f", a ,b) at graph 0.05,0.95 left;
    plot "openssh.dat" using 1:2 with points title "Versions", f(x) with lines title "Fit"
  '

          Which yields:

          Predict

          Use Y = (mX) + C, or Version = (9.55651e-09 * Date) -6.75132

          Code

          Note that Date are Epoch timestamps.

          export VERSION="43.2"

date +%Y-%m-%d -d \
 @$(
    export m="9.55651e-09";
    export c="-6.75132";
    ## Use python for better scientific number handling 
    python -c "print(($VERSION - $c)/$m)"
 )

          For OpenSSH version 43.2, the predicted date is:

          2135-08-21

          So, assuming a linear trend and no cataclysmic events that would pause development for a few thousand years, then it’s only 110 years into the future

      I saw a copy of Language of The Birds on a shelf at Amazon Ho Foods.
      Not sure how it got there, but my AI shopping cart drained my account just for looking at the book.
