Older versions of Cheetah?

I opened an old project from 2 years ago and some things don't seem to be rendering correctly. So I want to check it in the version I used, which would have been in February 2017. I went to the News section, which lists all the Cheetah release versions and found I would most likely have been using one of the 7.0 beta versions before the final 7.0 release on October 2017.

So:
(1) Anyone know what beta version was in circulation in Feb 2017?
(2) How can I download older versions? The site lists older versions but the one for v7.0 actually downloads most (nearly) recent v7.3.3.

NOTE: I also tried beta testers forum but the link there goes to a dead page.
 
Maybe this will help: https://www.cheetah3d.com/forum/index.php?threads/12243/

Frank that one links to 7.3.3 as well. But thanks anyway. I examined my scene more closely and it seems like the issue is with the membrane material, which has a high degree of noise I do not remember getting in the original project. Just wondering if the membrane shader might have changed since then?
 
Thanks Frank. Let me prepare the file. I don't need the entire scene rendered - just want to try and figure out why there is so much noise, and also very long render time.
 
Hi Pegot. I have a whole bunch of 7.0 beta releases, and other early versions of v7, which I can try to upload to my webspace if you like.

Pegot, beta 19 and beta 20 are from January 2017, then it jumps to beta 28, which is September 2017.

Maybe I'll try beta 20 ?
 
ok well I feel a little silly. First off I was working with a slightly wrong file but more importantly I realize now that when I brought the renders into After Effects, I applied a heavy amount of noise reduction from Neat Video - which is what ultimately gave me the look I wanted. And as for animation, looking back on the original renders I see each frame did take about 5 - 6 minutes.
 
Hey Paul I loaded my scene into v7 Beta 20 that you uploaded for me and there actually is a small difference in the rendering. The old beta version is a bit lighter and softer (which I like) and the arrangement of colors from the Particle Picker material are just slightly different.
