- CUPS Filters v2.0.0 release on 22 September 2023
  - The final 2.0.0 Release of the new cups-filters components!

  - universal: Enable application/vnd.cups-postscript as input
    There are filters which produce this MIME type (such as hpps of HPLIP), and if someone uses 
    such driver on a client and the server has an IPP Everywhere/driverless printer, the job 
    fails (Pull request #534, requires libcupsfilters 2.0.0).
