Older releases of Trisquel?

Hello,

I have a project I have been working on for several years. A couple of years ago, to demonstrate part of it, I decided to add all of the Ubuntu .iso files to it. I did not realize how many different Ubuntu releases there were and I have not been able to keep up with them. However, I recently added the gNewSense releases and I would now like to add the Trisquel releases.

I am in the process of downloading Trisquel 2.2.2, 3.0.1, and 3.5. Can anyone tell me what the prior releases of Trisquel were and if there is somewhere I can download the .iso and .md5 files of them?

Thanks
-Scott

The files I have done previously are viewable here, in case anyone is interested:
