I am on 4330 and still getting kinda false messages.
'LockOnRockets v0.3.0' is using deprecated hook 'OnActiveItemChanged', which will stop working on Wednesday, 01 January 2020. Please ask the author to update to 'OnActiveItemChanged(BasePlayer player, Item oldItem, Item newItem)'The point is, the plugin in question is already using the hook as suggested in the messsage. I am using the linux artifact.
