That only goes as far back as to version 1.8 from 2015. Electrum's GitHub releases date back to 0.56 from 2012 (https://github.com/spesmilo/electrum/tags?after=0.57a). I am not sure if it's possible to find versions of the software that are older than that. I think anything older than 3.3.4 can't connect to servers anyway.
