We are still actively working on this CMS and we added a lot of amazing features !
Now you can protect a page or the whole website with basic authentification. (Useful for mockups, private demo) Demo
You can run AQL request on server side then generate a partial with the result. It was doable to run such request before only within components (VueJS, RiotJS, etc...). It should help SEO.
Any change on models are now stored in a git repository ... So we keep any change you made in the CMS.
We are still thinking open sourcing the CMS (core part) when the code will be good enough.
