SphireOS Release 250.20 (Stable 2)

14 September, 2021

Welcome to SphireOS Release 250.20 (Stable 2)

New Features & Improvements

  • We improved the way that SphireOS handles YouTube and Wikipedia searches. SphireOS will be able to filter and report on searches in these two signatures to School Manager.


  • We found and fixed an exploit where users could manipulate the google image cache to access blocked YouTube videos.
  • We fixed a couple crashes, including one where SphireOS could crash when it encountered a signature with circular dependencies.
  • We found and fixed a memory leak with signature storage.
  • Rules that were supposed to apply at certain times of the day on certain days weren’t always taking effect as they should have.
