Summary
  • Fixed a bunch of false positives. Only the minority has been reported properly... Hopefully this can be improved in the future for tracking
  • Fixed a couple of bypasses. Most notably:
  • 3 block Nofall
  • A weird and slow upwards fly
  • Added a new check: Scaffold Type G
  • Added 1.21 support

In conjunction, some other things have been fixed.
Keep in mind that patches are not announced, due to the nature of the rolling releases provided by the loader.
