Please note that This Mjolnir version bump technnically is missing some extra stuff that mjolnir claims we should do but it didnt work when i tried it and well my mjolnir deployment has been running this since release day almost and its fine. No errors in log that are unexpected. (Mjolnir throws errors in the log for anyone who wonders for various things that are fine. Like if a protection is off that is an error. Its due to how matrix-bot-lib works.)
