[x3d-public] announce: x3d.py release 4.0.65.0 now deployed on Python Package Index (PyPi)

[John Carlson]

Clarification, Don, are all the archives stored on sourceforge, or just
.x3d files and associated images?  If there’s a whole lot of Python files,
I may hold back on downloading the whole thing from sourceforge and prefer
to do onesy-twosy downloads, from published pages @web3d.org.

I’m guessing the Example Archives and the sourceforge archive remains
separate.  If so, there’s no need to respond.  I’ll just wait a few days
before doing an update.

I also look for a new X3DUOM on sourceforge at that time.

Thanks,

John
