Version 2 is a complete rewrite of LibreKB, and I think you'll love it!

Tons of new features, really too much to list. But it's a complete rewrite on a modern MVC architecture, with a refreshed interface, overhauled user management, pretty URLs for better SEO, and tons more.
Note: docker support has been removed in v2. If the community really wants to add it back, go ahead, but I don't really see the point - LibreKB is meant to run on a web hosting account or web server.
