I improved some default values of the config file, but there's no need to delete your old config file. You can see the changes here: https://github.com/Olexorus/WitherAC/commit/158a96f04eeaffa73933346d11427bffc7e8ffb7

Changelog v0.17.1:
- I found out the ping spoof check has been broken and not working, this is fixed now
- increased the speed leniency when receiving knockback and tweaked some other speed values, it should now have less false positives while still detecting everything as good as before
- the packet spoof check was always enabled even if disabled in config or bypassed with permission, this is now fixed
- fixed speed false positives when a dolphin's grace effect expired but the player still had the momentum
- fixed a rare speed false positive when using riptide
- increased the default notification threshold
- added lower thresholds for the boat fly and packet speed check to the default config because those checks have been proven to be very accurate and usually false positive free
- refactored and cleaned up some stuff
