This update is a 2 parter. Part one Protocol Listener is no longer needed. Part two we can now support 1.20.4. Now we all know there is often a give and take with things the give here is 1.20.4 support the take it 1.20-.1.20.3 support. I didn't test each for sure but can say without a doubt 1.20 will no longer work sorry just update to .4 already
