Changelog

Fixes and Improvements

Fixes

  • Fixed a detection vector where OpSec didn't whitelist deprecated vanilla keys. Informed by @NikOverflow

Improvements

  • Improved debug alerts to show the packet origin of key payloads and filtering out whitelisted key noises.
  • Server resource pack keys are now resolved through normal vanilla key resolution instead of returning cached values.
