[2022] Multiplayer patch 0.9 release date?

Hello, I'm looking foward to play this game since the first announcements but haven't brought it yet because I like to play ARPG with my friend. I've seen that in patch 0.9 probably there will the possibility to play multiplayer, but what I did not found was the release date of this patch, is there one yet or at least an estimate? Thank you
