This is qpdf version 12.1.0. This release features a number of small bug fixes and feature enhancements including new CLI flags --remove-structure and --jpeg-quality for helping to create smaller PDFs. 12.1 is planned to be the last minor release to build with C++-17. We plan on requiring C++-20 starting in 12.2.
