SWEET, WikiJs 2 finally went from beta to stable.. Still missing some planned features as "coming soon" but its impressively feature rich and easy to install and manage!

I've been waiting for a good potential replacement to mediawiki better oriented for documentation!

If anyone wants to play around with it you can register account on my own instance here:
