How to extract and keep “old” Estuary version as .zip file?

Hello,

I loved Estuary at the state it had around early October, before Wall and InfoWall were changed (https://github.com/xbmc/xbmc/pull/10646).
Today I tested the big overhaul of Estuary and there are just too many changes I am not really happy with – no offense!

So I would like to keep this (lightweight) early October version for future releases.

Is it possible to somehow extract it as .zip file or just download it somewhere so I can manually install it from zip?
I have not been able to find a way yet.

Please help me out…
Thanks!
