We are all working hard on fixing the remaining issues for delivering a stable Godot 3.0 as soon as possible, but we definitely need a hand to speed up the work!
Because of this, we are re-launching the Hero Wanted campaign, this time it's the ultimate battle!
While most issues require more experience with the codebase, we have marked a good amount of issues with the "Hero Wanted!" tag. They include a description on how the problem can be approached, so it's great for new contributors unfamiliar with the code.
Feel free to join irc (#godotengine-devel) if you need assistance from other devs. We are counting on you!
