This is qpdf version 11.4.0. This release contains a few minor enhancements and bug fixes. Highlights include improving annotation flattenening to avoid losing annotations in certain technically incorrect but otherwise usable PDF files, and an enhancement to --optimize-images that allows it to traverse into form XObjects. This release also corrects a packaging error that was causing the MinGW DLL to be about 12 times larger than necessary.
