[How to Downgrade 0AD?]

Hi. I really love 0AD but hate the newest version. Is there anyway I can install an older version on Ubuntu 16.04?

Click the gear icon next to the ai player.

Thanks! I looked all over but missed that. The difficulty level was set to medium.

[New default difficultly level too high]

I really love 0AD but haven't been able to play it since the new version (0.0.20-1) I tried one of the new maps and got slaughtered 5 times in a row. I then decided to play one of the older maps that I've played and won dozens of times.  Usually I can reach level II, build 4+ barracks and a wall before I am attacked, but now I am getting attacked as soon as  i begin building the first two barracks. Is there any to change the difficulty level?
