Flex ➤ AAC Edition ➤ Flex AAC Edition passed the Alpha Phase!

I would like to thank everyone for supporting this project. We have successfully completed the ALPHA phase and are continuing with the BETA phase. This means that you can now use the config on your server. There will still be a risk that you may have false positives but there will also be a STABLE build soon as possible so you can use that without problems (hopefully). For now you have to do it with this. I'm going to try the next time to further optimize the checks and make clearer the notes of the settings of the checks etc.

The overview will be updated again soon so it will look better!

  • Fly check optimized.
  • Regen check optimized.
  • Jesus check optimized.
  • General section optimized.
  • Criticals check tweaked.
  • Heuristics check tweaked.
