There are 3 forks of AggPas that I know of, and the one included with
fpGUI is the most maintained version (features and bug fixes).

Ah, that would explain it. That is the original and FINAL release of
AggPas by Milano from many years ago. It doesn't support 64-bit, doesn't
support FreeBSD and had some bugs.
All those issues have been resolved in the AggPas included with fpGUI.

And if you look in the "develop" branch of fpGUI, there is an even later
AggPas version - last updated a month ago.

Yes, it is a bit confusing. No, the original AgPass from the crossgl.com
website is not being maintained for many years.
I think you main a valid point in your other mail about the unit header
comments. I'll update the header comments in fpGUI repository and make
sure that it mentions that it is beyond the origin 2.4-rm3 release.
And if you wondered why I don't have AggPas in its own repository?
AggPas is/has been integrated into fpGUI and is becoming the default
renderer for fpGUI's Canvas class. So it's a critical dependency
(and at the time I didn't know about Git Submodules). At least
I kept all the AggPas code in its own directory, but in hindsight,
I should probably have named that directory "render/aggpas/" and not
"render/software/". Umm, I might just change that before the
next fpGUI release.
