I pushed an important update for Electrs Pruned which prevents Bitcoin Knots and Bitcoin Knots (BLAKE2b) Companion from getting stuck when you do the next update if you have Electrs Pruned integrated with either of them. Be sure to update Electrs Pruned before updating Bitcoin Knots when the latter update comes out. If you accidentally forget and Knots gets stuck, you can just reboot the server and try again.
