is this project dead?

[maplant]

It’s not dead, but it’s not being actively worked on. I don’t think I pinned any of the demos to specific package versions so they’re prone to breaking. I’ll try to fix them up if I have some free time today

[maplant]

Just fixed this, master should compile now. Thanks for filling this issue!

[maplant]

My bad, spoke too soon. Seeing some weird errors.

[maplant]

Should be fine now.
