I'm happy to announce that preview site for Misago v4, next major release of Misago is now available!
This is VERY early iteration of v4 that I plan to work and improve on. Currently it's very basic forum software with super limited featureset. There are no user profiles, account verification, notifications, attachments or even search. Even theme is placeholder build with Bootstrap 4. I will be implementing proper theme at later time when I have more features in. But there are working foundations, plugin system ("Demo site" message on forum's index is actually a plugin) and GraphQL API.
Please note that preview site will be periodically reset. Use new Misago v4 development category on this forum to offer feedback or report problems or bugs. Thank you!
