It's time to bring the-frey's blood pressure down and banish those night terrors. The time has come to integrate mainline wasmd into juno!
This also means you don't have to use the patched binary supplied by the core team - you can build this update yourself.
More info on the updates in this change can be found on the release page.
The Upgrade is scheduled for block 364000, which should be about 1700 UTC on 2nd February 2022.
For unattended updates, cosmovisor is your friend.
