[gdal-dev] GDAL 3.7.0 Proj 6.3.1 strange behavior when performing NAD83(EPSG:4152) to NAD83 HARN(EPSG:4269) realization transformation

[David Klaus]

All,

If I understand correctly. Before we do anything else, we should try to
rebuilt our GDAL solution such that it uses at least Proj4 9.2.0, do I have
that right? Does anyone happen to know the minimum GDAL version compatible
with Proj4 9.2.0?

P.S. I am still working on the code example to repeat the issue I ran into.
