Updated for Minecraft version 1.17.1
Added variables to control if the start message and update messages show when joining servers.
You need to delete config file and load into a world OR add the 2 lines below BEFORE any server information in the config.
# display_start_message=0 # display_update_message=0
Result will look something like this:
You only have to do this if you want to change those settings. The mod will work fine without them. Keep the # in front of the lines for backwards compatibility with older versions of the mod before 1.13.
